ZESR/ZESR+ Overview
ZESRZTE Ethernet Smart Ringis a solution for solving the layer 2
loop problem (RFC 3619). Compared with STP, the biggest advan-
tage is that the link will switch and recover quickly when one way
is disconnected and the shortest time is 50ms.
ZESR is applicable with multi-ring area. Multi-ring is designated
that every level is an independent ring and low-level has two entry
points to connect with high-level ring. The highest level ring is
named as major-level ring and others are named as access rings.
Multi-area is named that there are many protection instances on
the same ring suitable to different service vlan. Their logic routes
are different and independent.
ZESR+ , in double nodes double uplinks networking, improves the
current ZESR to meet redundancy protection for uplink and node
at the same time in double nodes double uplinks networking.
