Intelligent Caching, Content Delivery, and Wide Area File Services for Cisco Routers
Figure 1. Cisco 2600, 2800, 3600, 3700, and 3800 Series Content Engine Network Module
The Cisco® 2600, 2800, 3600, 3700, and 3800 series Content Engine Network Modules (NM) offer the industry's first and only router-integrated application platform for accelerating data center-based applications, enabling consolidation of infrastructure into the data center.
The Content Engine Network Modules can be deployed with the following software options:
• Cisco ACNS (Application and Content Networking System) Software-Cisco ACNS software helps organizations of all sizes to reduce costs, increase productivity, and increase revenue by extending strategic applications and content from the data center to the branch. Cisco ACNS provides the following benefits:
– Web Application Acceleration-Accelerating delivery of enterprise application data to the enterprise edge
– Secure Web Content Access Management-Edge security, antivirus, and filtering capabilities stop unwanted traffic before it traverses the WAN
– Business Video-Eases the pains of delivering rich media (eLearning, webcasts) to remote users
• Cisco WAFS (Wide Area File Services) Software-Cisco WAFS provide users with LAN-like performance when accessing centralized file storage over the WAN. Through advanced protocol optimizations, intelligent data and metadata caching, and WAN optimizations, Cisco WAFS enables file storage consolidation into the data center, thereby providing significant reduction in the total cost of ownership (TCO) of storage, storage management, and data protection. Cisco WAFS provides the following benefits:
– File and Print Server Consolidation-Remove costly and difficult to manage file and print servers from the remote office
– Remote Branch Data Protection-With data consolidated into the data center, data can be protected centrally, eliminating the need for branch office backup systems
– File Access and Collaboration-Centralized file storage enables true global collaboration and minimizes the number of redundant copies of files in the enterprise
– Software Distribution-Advanced file caching techniques integrate seamlessly with software distribution systems that utilize CIFS for package delivery, eliminating the need for branch office software distribution servers
INTEGRATED APPLICATION ACCELERATION AND BRANCH-OFFICE ROUTING
By offering integrated application acceleration and branch-office routing in a single package, Cisco Systems® reduces the complexity and costs of value-added services, while optimizing WAN bandwidth and reducing operational costs. Organizations can take a phased approach, starting small with fewer services and incrementally adding services. For example-an organization can start with a simple service, such as accelerating security patch distribution or URL filtering, and then add video-based e-learning or corporate communications.
Compared to standalone appliances, the Content Engine Network Module in the branch-office router offers the following advantages:
• Physical Space Savings-The Content Engine uses a single network-module slot in a modular Cisco Integrated Services Router or legacy Cisco router
• Simple Power and Cable Management-The module takes advantage of the router power options, including DC power and redundant power
• Common Management Interface-The module can be configured and managed from the Cisco IOS® Software command-line interface (CLI)
• Choice of Network Interfaces for Maximum Flexibility-The internal Fast Ethernet interface on the router backplane provides seamless integration. The external Fast Ethernet interface provides maximum performance when connected to an external LAN switch such as the Cisco Catalyst family or Cisco Express family
• Separate Processor for the Content Engine Network Module Maximizes Availability-A service interruption on the Content Engine Network Module does not affect services on the router
• Lower Operational Costs-The module is covered under Cisco maintenance service for the router, minimizing network operational costs and complexity
The Content Engine Network Module provides a separate processor to run application acceleration and WAN optimization software within the Cisco 2600, 2800, 3600, 3700, and 3800 series routers. The Content Engine Network Module software communicates to the Cisco IOS Software in the router through the internal Fast Ethernet interface (Figure 2). The Cisco IOS Software can establish a console session to the Content Engine Network Module console through the service-module content-engine<slot>/0 session command. Module status is available with the Cisco IOS Software service-module content-engine<slot>/0 status command.
