摘要
In one embodiment, a Segment Routing gateway receives Segment Routing packets encapsulating native packets. The Segment Routing gateway stores the Segment Routing encapsulating headers. The native packets are communicated to a service function (or other device). Upon return, Segment Routing packets are generated including the returned native packets using correspondingly stored Segment Routing encapsulating headers, possibly updated with new policies. Segment Routing includes, but is not limited to, SRv6 and SR-MPLS. In one embodiment, the native packet is sent from a physical interface of the SR gateway to the service function, and returned to the SR gateway on one of its physical interface(s). In one embodiment, shared storage is accessible to both the SR gateway and the service function (or other device), so references (e.g., memory locations or pointers) are communicated between the SR gateway and the service function (or other device).
