ZESR Configuration
ZESR Overview
ZESR Introduction
With the integration of data, voice , video and IP, the demand for
network reliability and network fault convergence time are raised
in the recent years. To shorten the time of network fault conver-
gence, ZTE provides ZESR (ZTE Ethernet Smart Ring).
ZESR is based on EAPS (RFC 3619) and improved on it. ZESR
checks if the ring is proper and ensures that there is only one
logical link between any two nodes, which effectively prevents the
broadcast storm caused by data loop. When there is a fault on
link or device of Ethernet ring, logic route will be switched quickly
to ensure the service recover soon. ZESR protocol is more simple
