Active call context reconstruction for primary/backup resource manager servers |
摘要 |
A method and apparatus for network server recovery maintains an ongoing call by reconstructing its call context from a server-state attribute (SSA) that is generated by a first server, recorded in separate storage and retrieved by a second server in the event that a connection to the first server is interrupted. The SSA encodes call data that can be used to enable a server to maintain the call. The separate storage is preferably associated with a network access server (NAS) that does not itself use the SSA.
