This course provides an overview of the

networking solutions for Huawei NGN earer

network !central office and re"ote office# $

focusing on the e%uip"ent selection and

networking configuration of the central office

networking. The central office is the core of the

NGN earer network and has high securit$ and

reliailit$ re%uire"ents on networking

structure. The networking structures involved

in this course are "ature solutions that have

stood stringent selection and tests& and have

een put into application.

+ua",P"ane Structure of the NGN -P Backbone

It is reco""ended that the ackone of the NGN I earer network adopt a private network with the

dual*plane structure. 9hen planning the network topolog$& design two planes sharing the active*

stand$ relation. Each plane is an independent network and is connected to the other plane through

connection links. In addition to the dual*plane design& deplo$ proper technical "easures& such as I

2-- and interface ackup& to guarantee fast convergence of the network in case faults occur.
