Abstract:
In one embodiment, a segment routing and tunnel exchange provides packet forwarding efficiencies in a network, including providing an exchange between a segment routing domain and a packet tunnel domain. One application includes the segment routing and tunnel exchange interfacing segment routing packet forwarding (e.g., in a Evolved Packet Core (EPC) and/or 5-G user plane) and packet tunnel forwarding in access networks (e.g., replacing a portion of a tunnel between an access node and a user plane function for accessing a corresponding data network). In one embodiment, a network provides mobility services using a segment routing data plane that spans segment routing and tunnel exchange(s) and segment routing-enabled user plane functions. One embodiment uses the segment routing data plane without any modification to a (radio) access network (R)AN (e.g., Evolved NodeB, Next Generation NodeB) nor to user equipment (e.g., any end user device).

Claim (Index 22):
The method of  claim 20 , including particular update operations in a user equipment handover from using the access node and the segment routing and tunnel exchange to using a second access node and a second segment routing and tunnel exchange, with said update operations including:\n updating, by the particular router in response to an update notification from a Session Management Function (SMF) or a Mobility Management Entity (MME), the specific address to be an address of the second access node, and updating the first particular segment identifier to be a second address of the second segment routing and tunnel exchange with the second address including an identification of a downlink segment routing function of the second segment routing and tunnel exchange and including the tunnel endpoint identifier; and receiving, by the second access node, the particular IP destination address that is an address of the second segment routing and tunnel exchange, with the particular IP destination address identifying an uplink segment routing function of the second segment routing and tunnel exchange.
