Cisco WebEx Node for Cisco ASR 1000 Series
Product Overview
The Cisco WebEx™ node is a shared port adapter (SPA) for the Cisco
®
ASR 1000 Series that
integrates transparently with the Cisco WebEx collaboration cloud. The shared port adapter runs
WebEx software that enables the module to act like a private extension of the WebEx service.
The Cisco WebEx node for the Cisco ASR 1000 Series provides enhanced performance and
reduced bandwidth consumption for WebEx web/voice over IP (VoIP)/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 for ASR 1000 is shown in Figure 1.

This capability will allow much of the “heavy lifting,” including voice, video, and desktop sharing,
required for large-scale WebEx meeting application deployments to be moved to the internal side
of the proxy server/firewall infrastructure. This will reduce the load on the proxy server/firewall
infrastructure and will also substantially reduce the peak bandwidth requirements for a large
enterprise. The meeting switching fabric is fully distributed across the WebEx collaboration cloud
and the WebEx node infrastructure within the enterprise. Attendees on the public Internet will still
connect to the WebEx hosted infrastructure. VoIP/video performance and overall latency for the
service will be substantially improved. Figures 2 and 3 compare what the deployment looks like
when deploying WebEx with and without the Cisco WebEx node on the Cisco ASR 1000 Series.
