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 19):
A method, comprising:\n receiving a specific packet by a particular router of a network from a data network; generating, by the particular router, a specific segment routing packet comprising the specific packet encapsulated therein and a segment routing header, the segment routing header including a segment list comprising a plurality of segment identifiers, with the plurality of segment identifiers including a first particular segment identifier and a second particular segment identifier, with the first particular segment identifier being an address of a segment routing and tunnel exchange and including an identification of a downlink segment routing function and a tunnel endpoint identifier, and with the second particular segment identifier including a specific address of an access node; sending the specific segment routing packet from the particular router; receiving the specific segment routing packet by the segment routing and tunnel exchange; generating, by the segment routing and tunnel exchange according to the downlink segment routing function, a specific tunnel packet comprising the specific packet encapsulated therein and one or more headers including a destination address of the specific address obtained from the second particular segment identifier and the tunnel endpoint identifier obtained from the first particular segment identifier; and sending the specific tunnel packet from the segment routing and tunnel exchange.
