BT Exact has verified the non-stop routing functionality on the Alcatel 7450 Ethernet Service Switch (ESS). Alcatel engaged the professional services of BT Exact to assist in the test and evaluation of the Alcatel 7450 Ethernet Service Switch (ESS-7) for high-availability features.
The BT Exact tests were designed to stretch the challenging conditions at the edge of large IP/MPLS networks by simulating hundreds of peers, thousands of routes and SLA-based services. Tests verified non-stop services during a control plane switchover, which demonstrated the Alcatel 7450 ESS’s service awareness and routing protocol reconvergence performance. Another test verified the platform’s ability to continue processing topology routing updates during a control plane switchover, thereby ensuring customer traffic was always forwarded over a valid route. In addition, the tests demonstrated that Alcatel’s non-stop routing implementation is transparent to and fully interoperable with adjacent routers from other vendors.
