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.
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.
