Overview of the Cisco WebEx Node for
the Cisco ASR 1000 Series Routers

This chapter provides an overview of the release history, features, and MIB support for the Cisco WebEx Node on the Cisco ASR 1000 Series Aggregation Services Routers. The Cisco WebEx Node is a shared port adapter (SPA) that provides enhanced performance and reduced bandwidth consumption for WebEx web, VoIP, and video sessions in a large enterprise.

This chapter includes the following sections:

Overview of the Cisco WebEx Node SPA Environment

The Cisco WebEx Node is a SPA for the Cisco ASR 1000 Series Aggregation Services Routers that integrates transparently with the Cisco WebEx collaboration cloud. The SPA runs WebEx software that enables the Cisco WebEx Node module to act like a private extension of the WebEx service.

The Cisco WebEx Node for the Cisco ASR 1000 Series Aggregation Services Routers provides enhanced performance and reduced bandwidth consumption for WebEx web, VoIP, and video sessions in a large enterprise. This is achieved by extending the hosted Cisco WebEx collaboration cloud into a large enterprise by deploying primary software components of the WebEx platform to an embedded processor within the onsite router.

The Cisco WebEx Node SPA is a full-height SPA that is designed to run an application that is a part of the Cisco WebEx Data Center. The Cisco WebEx Node SPA improves the functionality of WebEx meeting services by adding the meeting servers into the SPA itself. This technology provides the following advantages:

  • Improves performance for users inside the company firewall.
  • Reduces the bandwidth going out of the company firewall (to the WebEx Data Center).
  • Provides better security by reducing traffic outside the company firewall.

Software that runs on the Cisco WebEx Node for the Cisco ASR 1000 Series Aggregation Services Routers includes Cisco WebEx collaboration cloud software components that are integral to meeting collaboration and voice and video conferencing. By moving these components and functions into the Cisco WebEx Node SPA, the Cisco WebEx clients in the enterprise network have to connect only to the Cisco WebEx Node SPA. This reduces the traffic between the enterprise network and the Cisco WebEx Data Center, greatly reducing the customer’s internet bandwidth requirements.

By moving the switching components of the Cisco WebEx collaboration cloud into the Cisco WebEx Node for Cisco ASR 1000 Series Aggregation Services Routers, the Cisco WebEx clients in the enterprise network have to connect only to the Cisco WebEx Node SPA. This reduces the traffic between the enterprise network and the Cisco WebEx Data Center, greatly reducing the customer’s internet bandwidth requirements, as shown in Figure 21-1.

Instead of individual meeting streams from the Cisco WebEx Data Center to the enterprise, the use of the Cisco ASR 1000 Series Aggregation Services Routers to implement some of the Cisco WebEx conferencing functions allows for a single meeting stream from the Cisco WebEx Data Center to support enterprise conferencing traffic.

Figure 21-1 Cisco WebEx Network

 

Each Cisco WebEx Node SPA can be configured to perform either web conferencing or voice and video conferencing, but not both at the same time. Each Cisco WebEx Node SPA uses the same software package that includes both features; but the conferencing feature that actually runs on each SPA is determined by the Cisco WebEx Service Plan that the customer has purchased. The WebEx Data Center retains the Cisco WebEx Node SPA configuration files that the SPA retrieves each time the SPA boots. Multiple Cisco WebEx Node SPAs can be installed on the same Cisco ASR 1000 Series Aggregation Services Router to increase performance or to provide coverage for both media and video or VoIP sessions.

Supported Features

The Cisco WebEx Node for the Cisco ASR 1000 Series Aggregation Services Routers includes basic features:

  • 4-GB RAM
  • 250-GB hard disk drive, with self-monitoring, analysis, and reporting technology (SMART) support for application data and system log storage
  • Faceplate LEDs to indicate SPA status, hard disk drive activity, and system status
  • A Shutdown button to stop hard drive access activity before removing the SPA to prevent data corruption

Restrictions

  • Performance can be affected if there is a slow connection to the WebEx Data Center because communication between different Cisco WebEx Node SPAs has to go through the WebEx Data Center.
  • Before the Cisco WebEx Node SPA is removed, the software and the hard drive should be gracefully shut down, either using the Shutdown button or the hw-module subslot stop command.
  • Either web conferencing or voice and video conferencing are supported, but both are not supported on the same Cisco WebEx Node SPA.
  • The Cisco ASR 1002-X Router was introduced in Release 3.7.0S. This router does not support the Cisco WebEx Node SPA.
