Managing network access server group using multichassis multilink point-to-point protocol involves network access server registration/deregistration so address list of server always has current state of servers in group

摘要

The network access server group management method involves each network access server (ZS1-ZSN) of the group managing an address list of the remaining network access servers of the group. The registration and/or deregistration of a new network access server (ZSN+1) in or from the group is caries out so that an address list of a server always has the current state of the servers in the group. An independent claim is also included for a network access server.
