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 24):
The method of  claim 23 , comprising:\n receiving, by the segment routing and tunnel exchange, a second specific segment routing packet comprising a second specific packet encapsulated therein and a second segment routing header, the second segment routing header including a second segment list comprising a second plurality of segment identifiers, with the second plurality of segment identifiers including a third particular segment identifier and a fourth particular segment identifier, with the third particular segment identifier being an address of the segment routing and tunnel exchange and including an identification of the downlink segment routing function and an argument comprising a second tunnel endpoint identifier, and with the second particular segment identifier including an access node address; generating, by the segment routing and tunnel exchange according to the downlink segment routing function, a second specific tunnel packet comprising the second specific packet encapsulated therein and one or more headers including a destination address of the access node address obtained from the second particular segment identifier and the second tunnel endpoint identifier obtained from the first particular segment identifier; and sending the second specific tunnel packet from the segment routing and tunnel exchange.
