A system and method for facilitating communication with segment routing in a cable modem network environment may be provided. A pseudowire (PW) control packet including segment routing information including a PW segment identifier (SID) for establishing a data session between the RPD and a network element over a packet switched network is received at a remote physical device (RPD). The PW SID may be 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 are emulations of a point-to-point connection between the RPD and the network element. A mapping between the PW SID and the data session is written into a segment table of the RPD.
