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 the following figure.
