CISCO 828 G.SHDSL ROUTER

Business-Class Features for Small Offices and Teleworkers through the Power of Cisco IOS® Technology

The Cisco 828 G.SHDSL Router provides business-class functionality for small offices and teleworkers through the power of Cisco IOS® technology. It enables service providers and resellers to increase service revenue by supporting features for business-class security, differentiated classes of service, and managed network services with Cisco IOS Software. These value-added features, along with the manageability and proven reliability of Cisco IOS technology, provide the mission-critical networking that businesses require.

Figure 1. Cisco 828 G.SHDSL Router

The newest member of the award-winning Cisco 800 Series Routers, the Cisco 828 G.SHDSL Router, provides small offices and teleworkers the features they need for mission-critical applications. (See Figure 2.) It also gives service providers a platform that allows them to offer high-margin, value-added business services while helping them reduce the cost of deployment and services.

G.SHDSL is the latest version of DSL technology, and it provides businesses a symmetrical service for bandwidth-intensive applications. G.SHDSL can support speeds both upstream and downstream of up to 2.3 Mbps and can reach customers as far as 20,000 feet from the telco/PTT office. G.SHDSL is a standards-based technology, and the Cisco 828 Router supports the ITU G.991.2 standard.

The Cisco Systems portfolio of G.SHDSL customer premises equipment (CPE), all based on Cisco IOS Software, serves all business-customer segments from small offices and teleworkers to branch offices. With the Cisco G.SHDSL CPE, service providers can deploy value-added services to an expanded customer base of users who require advanced, business-class features. Additionally, Cisco and its DSL CPE can help service providers reduce their operational expenses.

BUSINESS CLASS FEATURES FOR VALUE-ADDED SERVICES

The Cisco 828 Router is ideal for users in a small office or for teleworkers, supporting scalable, secure, quality, and proven business solutions such as:

• Business-class security

• Differentiated classes of service

• Managed access with service level agreements (SLAs)

Figure 2. The Cisco 828 Business-Class G.SHDSL Router is ideal for a small office or as a telecommuting solution to provide secure and reliable access to the Internet or corporate offices.

Business-Class Security

To take advantage of the unprecedented opportunities offered by communications and commerce over the Internet, private information must remain secure. With Cisco IOS Software, the Cisco 828 Router provides basic network security features such as standard and extended access control lists (ACLs), generic routing encapsulation (GRE) tunneling, and Network Address Translation (NAT), which hides private IP addresses behind a single public IP address.

With the always-on connection that DSL provides, it is essential to provide perimeter security with a firewall. Beyond simple packet filtering, the Cisco 828 Router provides a stateful inspection firewall with the Cisco IOS Firewall Feature Set. A stateful inspection or dynamic firewall provides a greater level of security intelligence by allowing or preventing network access based on a session's state. The firewall will allow traffic to pass when requested by a user behind the firewall but will prevent unauthorized network access.

Additionally, when using a public network such as the Internet to connect remote offices and teleworkers, additional security measures must be taken to make those connections secure for business communications. Virtual private networks (VPNs) use security encryption and tunneling technology to make connections over a public network secure. The Cisco 828 Router supports VPNs with the strongest form of encryption, 3DES IPSec, to allow businesses to save money by using low-cost connections to the Internet without sacrificing the security that private leased lines provide. Furthermore, firewall and VPN features enable service providers and resellers to offer revenue-generating value-added services beyond simple Internet access.

The Cisco 828 Router supports the Cisco Easy VPN Remote feature which allows Cisco 800 Series routers to act as remote VPN clients. As such, these devices can receive predefined security policies from the headquarters' head-end, thus minimizing the VPN configuration required at the remote location. This cost effective solution is ideal for remote offices with little IT support, or large CPE deployments where it is impractical to individually configure multiple remote devices. For those at remote offices, the Cisco Easy VPN Remote feature can be configured with the Cisco Router Web Set Up tool (CRWS) Web-based GUI. This makes VPN configuration as easy as entering a password, increasing productivity and lowering costs as the need for local IT support is minimized.

The Cisco 828 Router also supports the Cisco Easy VPN Server feature in Cisco IOS Release 12.2(8)T, or later releases. This allows a Cisco 800 Series router to act as a VPN head-end device in site-to-site VPNs where the remote office routers are using the Easy VPN Remote feature. Policies can then be pushed down to the remote office routers. In addition to terminating site-to-site VPNs, a Cisco 800 running Cisco Easy VPN Server can terminate VPN tunnels initiated by mobile remote workers running VPN client software on PCs. This flexibility makes it possible for mobile and remote workers, such as sales people on the road, to access their headquarters' intranet where critical data and applications exist.

DIFFERENTIATED CLASSES OF SERVICE

The Cisco 828 Router enables service providers to increase revenue by building differentiated service options based on premium, standard, or best-effort service classes.

It employs quality-of-service (QoS) features such as application-aware networking with IP QoS features and traffic management with ATM QoS features. This enables the router to expedite the handling of mission-critical or delay-sensitive applications, such as enterprise resource planning (ERP) or videoconferencing, while sharing network resources with lower-priority applications such as Web surfing.

By providing QoS features at the edge of the network, applications such as video or IP telephony can more efficiently use network bandwidth, and users of mission-critical applications in remote locations can gain the benefits of traffic management.

APPLICATION-AWARE NETWORKING WITH IP QoS

Through Cisco IOS Software, the Cisco 828 Router supports the following IP QoS features:

• Low Latency Queuing (IP QoS)

• PPP fragmentation and interleaving (PPP QoS)

• Policy-based routing (IP QoS)

• Weighted Random Early Detection (IP QoS)

Using Low Latency Queuing (often called LLQ or PQCBWFQ), the Cisco 828 Router enables service providers and resellers to guarantee or differentiate bandwidth based on a specific application or a specific user. For example, the order entry department traffic can be given priority over the marketing department traffic. The ability of the Cisco 828 Router to restrict the bandwidth of certain applications or users allows service providers and resellers to manage traffic on the basis of application or user requirements.

TRAFFIC MANAGEMENT USING ATM QOS

In addition to IP QoS features, the Cisco 828 Router provides ATM QoS features including:

• Per-virtual-circuit queuing (ATM QoS)

• Traffic management (ATM QoS)

• Class based traffic policing with clp tagging (ATM QOS)

These features enable service providers to manage their core ATM network infrastructures to deliver scalable, cost-effective services with QoS guarantees to their customers. Per-virtual-circuit traffic shaping and queuing allow further optimization of the existing bandwidth between customers and various services. Service Providers can use features to mark and drop traffic that exceed service contract limits which can optimize the network during times of congestion.

MANAGED NETWORK ACCESS WITH SERVICE-LEVEL AGREEMENTS

Service providers can offer small-offices and enterprise telecommuters managed network or Internet access with the Cisco 828 Router, providing service-level agreements (SLAs) and response time. SLAs can be a critical requirement in serving the business market that is accustomed to uninterrupted service with traditional WAN services such as T1 lines or Frame Relay.

When deploying business services with multiple Cisco 828 Router, service providers can use tools to provision and monitor these services. The Cisco 828 Router supports the SA Agent feature in Cisco IOS Software that enables the monitoring of SLAs all the way to the customer site. Additionally, in deploying VPNs with multiple Cisco 828 Routers, service providers can use the Cisco VPN Solutions Center software to set up VPN connections between customer sites.

REDUCED OPERATIONAL COSTS

Because the Cisco 828 Router is based on Cisco IOS technology, service providers and resellers can leverage their training and investments in Cisco IOS Software to reduce their overall costs of doing business. With key management and troubleshooting features, service providers and resellers can cost-effectively deploy and manage the Cisco 828 Router at the business customers' premises, thanks to the following advantages:

• Cisco IOS manageability, including interactive diagnostics/debugging features

• Familiar Cisco IOS command-line interface (CLI)

• Proven reliability

CISCO IOS SOFTWARE MANAGEABILITY

The Cisco 828 Router incorporates the same Cisco IOS technologies used by service providers and enterprises, allowing service providers and resellers to use existing knowledge of Cisco IOS Software to reduce training costs when configuring, installing, and deploying a Cisco 828 Router. Additionally, Cisco IOS Software provides many debug features that allow a service provider to diagnose network problems remotely. This can eliminate costly service calls or truck rolls, as well as reduce customer equipment returns when issues cannot be quickly solved.

PROVEN RELIABILITY

Because Cisco 800 Series routers are based on the same proven Cisco IOS technology used on 80 percent of the Internet and because Cisco IOS Software is the industry-standard application for mission-critical enterprise networks, small-business and enterprise telecommuters can depend on them day after day, year after year.

EASY DEPLOYMENT AND SET-UP

The Cisco 828 Router includes the Cisco Router Web Setup tool (CRWS), a Web-based configuration tool that allows users to self-install the router quickly without needing a working knowledge of Cisco IOS Software. Because CRWS is Web-based, no additional software needs to be installed on a user's PC. The user simply needs to point a browser to the router and follow a few simple steps to get the router up and running quickly.

Additionally, Cisco offers its free Configuration Express, a Web-based e-commerce system and customized in-line manufacturing process, for Service service-provider partners who buy directly from Cisco where Cisco ships preconfigured routers to the end user. Service providers can use Configuration Express to save on the cost of deployment logistics, time, and warehousing of products. Cisco Configuration Express is an example of a Cisco e-business application that empowers service providers to deploy products more efficiently while reducing costs and decreasing lead times.

CISCO/라우터 & 라우팅 시스템 2007/05/04 00:54

Cisco 827H ADSL Router

Business Class ADSL Access through the

Power of Cisco IOS® Technology

The Cisco 827H ADSL Routers provides business-class functionality for small offices ands corporate teleworkers through the power of Cisco IOS technology. The Cisco 827H Router enables service providers and resellers to increase service revenue by supporting features for business-class security, differentiated classes of service, and managed network access. These value-added features, along with the manageability and proven reliability of Cisco IOS technology, provide the mission-critical networking that businesses require.

Figure 1:

Cisco 827H ADSL Router

The Cisco 827H ADSL Router enables value added services including managed, secure Internet and VPN access for small remote offices, teleworkers and small to medium sized businesses. At the same time, the Cisco 827H Router helps reduce operational costs for business, resellers and service providers with simplified set up and remote management and troubleshooting tools provided by Cisco IOS software (see Figure 1).

Value-Added Services

The Cisco 827H Router is ideal for a small business or remote office or as an enterprise telecommuting solution. It has an integrated four port hub for up to four devices or with an external hub or switch support additional users (recommended up to 20 users). This Cisco 827H Router supports scalable, secure, and proven business solutions such as:

Benefits of Cisco 827H Router Business-Class ADSL Router

Business-Class Security for Internet and VPN Access

To take advantage of the unprecedented opportunities offered by Internet-bases communications and commerce, private information must remain secure. Cisco IOS software provides many features to enable network security and the Cisco 827H Router includes a stateful firewall. It denies or permits WAN traffic based on a session's state, so requests from users behind the firewall can be received, whie preventing unauthorized access. Additionally, Cisco IOS software includes additional perimeter security features such as standard and extended access control lists (ACLs); Lock and Key (dynamic ACLs); router and route authentication; generic routing encapsulation (GRE) tunneling; and Network Address Translation. The perimeter security features control traffic entry and exit between private networks, intranets, extranets, or the Internet.

Beyond Firewall security the Cisco 827H Router also supports optional data encryption for Virtual Private Networks. VPNs allow secure communication over a public infrastructure such as the Internet. While a firewall provides perimeter network security for a given location, VPNs protect data when sent from one site to another, such as a branch office to corporate headquarters. VPNs use data encryption and secure tunnels to protect the integrity and confidentiality of data traveling over these public connections. The Cisco 827H Router supports IPSec 3DES encryption, which provides the most secure form of data encryption, and prevents hackers from gaining access to corporate information.

To simplify the setup of VPNs at remote locations the Cisco 827H Router supports Cisco Easy VPN. The Cisco Easy VPN Remote feature allows a Cisco router with a static or dynamic IP address to automatically establish and maintain a VPN tunnel to a Cisco VPN server or concentrator. This allows the same ease of configuration and ongoing policy management of VPNs as VPN software clients. This cost effective solution is ideal for remote offices with little IT support, or large CPE deployments where it is impractical to individually configure multiple remote devices. For those at remote offices or teleworkers, the Cisco EasyVPN Remote feature can be configured with the Cisco Router Web Set Up tool (CRWS), a Web-based GUI. This makes VPN configuration as easy as entering a password, increasing productivity and decreasing support costs.

Differentiated Classes of Service

The Cisco 827H business-class ADSL router enables service providers to increase revenue by building differentiated service options based on premium, standard, or best-effort service classes.

It employs quality-of-service (QoS) features such as application-aware networking with IP QoS features and traffic management with ATM QoS features. This enables the router to expedite the handling of mission-critical or delay sensitive applications, such as enterprise resource planning (ERP) or videoconferencing while sharing network resources with lower-priority applications such as Web surfing.

Application-Aware Networking with IP QoS

Using Class-Based Weighted Fair Queuing (CBWFQ), the Cisco 827H Router enables service providers and resellers to guarantee or differentiate bandwidth based on a specific application or a specific user. For example, the order entry department traffic can be given priority over the marketing department traffic. For real time applications explicit low latency can be added using the low latency queuing, (LLQ) providing low delay and guaranteed bandwidth to real-time applications while providing the same differentiated bandwidth support as CBWFQ.

Traffic Management Using ATM QoS

In addition to IP QoS features, the Cisco 827H Router provides ATM QoS features that enable service providers to manage their core ATM network infrastructures to deliver scalable, cost-effective services with QoS guarantees to their customers. Per-virtual-circuit traffic shaping and queuing allow further optimization of the existing bandwidth between customers and various services. For congested ATM networks the router provides support for traffic policing with Cell Loss Priority (CLP) tagging options to allow the ATM network to drop all the cells from packets that exceed the policy or that have been identified as having less priority than other traffic.

Using the following features, service providers can offer true QoS and cater to applications with special requirements:

•Per-virtual-circuit queuing (ATM QoS)

•Traffic management (ATM QoS)

•Class-Based Weighted Fair Queuing (IP QoS)

•Policy-based routing (IP QoS)

•Weighed Random Early Detection (IP QoS)

Managed Network Services with Cisco IOS Software

Service providers can offer small business and enterprise telecommuters managed network or Internet access with the Cisco 827H Router, providing service level agreement (SLAs) and response time guarantees. Through Cisco IOS software, the Cisco 827H Router provides complete remote management features, which allow service providers to monitor the lines of the customers with SLAs and quickly react to any distruption in service.

Reduced Cost of Operations

Cisco IOS Software Manageability

The Cisco 827H Router incorporates the same Cisco IOS technologies used by service providers and enterprises, allowing service providers and resellers to use existing knowledge of Cisco IOS Software to reduce training costs when configuring, installing, and deploying Cisco 827H ADSL routers. Additionally, Cisco IOS Software provides many debug features that allow a service provider to remotely diagnose network problems. The Cisco 827H router supports centralized administration and management via Simple Network Management Protocol (SNMP), HTTP, Telnet, or local management through the router console port. The world-class support offered by the Cisco Technical Assistance Center (TAC) provides unparalleled support services.

Easy to Deploy and Setup

The Cisco 827H Router includes the Cisco Router Web Set Up tool, a Web-based configuration tool for simplified installation and setup. To configure the product, users simply point a Web browser to the IP address of the router and follow a few simple steps. This allows the Cisco 827H Router to be readily installed by non-technical personnel or end users. The setup tool allows a user to enable security, such as packet filtering, as well as the Cisco IOS Software Firewall Feature Set.

Additionally, Cisco offers at no additional cost, Cisco Configuration Express for direct purchase partners which allows Cisco to ship pre-configured routers to end users. Service Providers, System Integrators and Enterprises can utilized Conguration Express to save on the cost of deployment logistics and warehousing of products. Cisco Configuration Express also enables true plug and play deployments of Cisco 827H Routers without the need for any configuration tools through custom loaded configurations.

Proven Reliability

Because Cisco 800 Series routers are based on the same proven Cisco IOS technology used on 80 percent of the Internet and because Cisco IOS Software is the industry-standard application for mission-critical enterprise networks, small business and enterprise telecommuters can depend on them day after day, year after year.
