Transport Features: Ethernet Path Protection 6 Mbps

10 Mbps 4 Mbps

4 Mbps

Tejas Networks Proprietary and Confidential, Nov 2006

10 Mbps traffic is provided by giving 6 Mbps (3 VC-12) along the blue path and 4 Mbps (2 VC-12) along the red path between the ingress and egress node. In case of failure as shown in the figure the bandwidth would come down to 4 Mbps without the traffic being hit This would provide protection for at least 4 Mbps of traffic even when there is a fiber cut and hence a cheaper solution compared to full protection but clear differentiator compared to unprotected connection.
