US 2016/0366052 A1 · COMMUNICATION WITH SEGMENT ROUTING IN A CABLE MODEM NETWORK ENVIRONMENT

Abstract

An example system and method for facilitating communication with segment routing in a cable modem network environment is provided and includes receiving, at a remote physical device (RPD) in a network, a PW control packet including segment routing information including a PW segment identifier (PW SID) for establishing a data session between the RPD and a network element over a packet switched network, the PW SID indicative of a segment in the packet switched network to be used for communicating PW data packets of the data session, the PW control packet and the PW data packets being emulations of a point-to-point connection between the RPD and the network element, and writing into a segment table of the RPD a mapping between the PW SID and the data session. In specific embodiments, the network element comprises a Converged Cable Access Platform (CCAP) Core of a cable network.

A method comprising:

receiving, at a remote physical device (RPD), a pseudowire (PW) control packet comprising segment routing information including a PW segment identifier (PW SID) for establishing a data session between the RPD and a network element over a packet switched network, the PW SID indicative of a segment in the packet switched network to be used for communicating PW data packets of the data session, the PW control packet and the PW data packets respectively carrying control information and data, and comprising emulations of a point-to-point connection over the packet switched network between the RPD and the network element;
and
writing into a segment table of the RPD a mapping between the PW SID and the data session.

Non-transitory tangible computer readable media that includes instructions for execution, which when executed by a processor of a RPD, performs operations comprising:

receiving, at the RPD, a PW control packet comprising segment routing information including a PW SID for establishing a data session between the RPD and a network element over a packet switched network, the PW SID indicative of a segment in the packet switched network to be used for communicating PW data packets of the data session, the PW control packet and the PW data packets respectively carrying control information and data, and comprising emulations of a point-to-point connection over the packet switched network between the RPD and the network element;
and
writing into a segment table of the RPD a mapping between the PW SID and the data session.

An apparatus, comprising:

a memory element for storing data;
and
a processor, wherein the processor executes instructions associated with the data, wherein the processor and the memory element cooperate, such that the apparatus is configured for:
receiving, at the apparatus, a PW control packet comprising segment routing information including a PW SID for establishing a data session between the RPD and a network element over a packet switched network, the PW SID indicative of a segment in the packet switched network to be used for communicating PW data packets of the data session, the PW control packet and the PW data packets respectively carrying control information and data, and comprising emulations of a point-to-point connection over the packet switched network between the RPD and the network element;
and
writing into a segment table of the apparatus a mapping between the PW SID and the data session.
