Benefits of Cisco 826 Router Business-Class ADSL Router

Business-Class Security for Internet and VPN Access

To take advantage of the unprecedented opportunities offered by Internet-based communications and commerce, private information must remain secure. Cisco IOS software provides many features to enable network security and the Cisco 826 Router offers a stateful inspection firewall. It denies or permits WAN traffic based on a session's state, so requests from users behind the firewall can be reached, while presenting 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. These perimeter security features control traffic entry and exit between private networks, intranets, extranets, and the Internet.

Beyond Firewall security the Cisco 826 Router also supports optional data encryption for Virtual Private Networks. VPNs allow secure communications over a public infrastructure such as the Internet. While a firewall provides perimeter network security for give 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 826 Router supports IPSec encryption, which provides the most secure form of data encryption, and prevents hackers from gaining access to corporate information.

To simply the set up of VPNs at remote locations the Cisco 826 Router supports Cisco Easy VPN. The Cisco Easy VPN Remote feature allows 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 remote offices or teleworkers, the Cisco Easy VPN 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 826 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 826 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 826 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

Service providers can offer small business and enterprise telecommuters managed network or Internet access with the Cisco 826 Router, providing service level agreement (SLAs) and response time guarantees. Through Cisco IOS software, the Cisco 826 Router provides complete remote management features, which allow service providers to proactively test the line's uptime and performance. In doing so, service providers can monitor the lines of customers with SLAs and quickly react to any disruption in service.

Reduced Cost of Operations

Cisco IOS Software Manageability

The Cisco 826 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 826 ADSL routers. Additionally, Cisco IOS software provides many debug features that allow a service provider to remotely diagnose network problems. The Cisco 826 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 Cisc 826 Router includes the Cisco Router Web Setup 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 826 Router to be readily installed by non-technical personnel or endusers. The setup tools 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 utilize Configuration 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 826 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.
