Method, topology and point of presence equipment for serving a plurlaity of users via a multiplex module

摘要

A number of users interface with a network via a multiplex module, on a communication path established between the multiplex module and a point of presence. Some users may be served by one or more first channels of the communication path while one or more remaining users may be served by one or more additional channels of the communication path. Users having a basic service level agreement may be served by the first channels while users having an extended service level agreement may be served by the one or more additional channels. Allocation of users to distinct channel types based on their service level agreements may apply at a primary point of presence or may apply at a redundant point of presence.

主权项

1. A method of providing redundant connections to N users interfacing with a network via a multiplex module, comprising:
detecting, at a point of presence (POP), a communication failure between the multiplex module and a peer POP; serving via a channelizer N−M of the N users via S first channels of a communication path established between the POP and the multiplex module, the communication path having K+S installed channels; and serving via the channelizer M remaining users via K second channels of the communication path, wherein the POP comprises at least one of:
a database for storing a service level agreement (SLA) parameter value for each of the N users and for providing the SLA parameter values to the channelizer, the SLA parameter values indicating a normal service level for the N−M users and a preferred service level for the M remaining users; anda time division multiplexer for sequentially assigning a bandwidth of the S first channels of the communication port to the N−M users.
