Abstract: Provided is a communication system comprising: a controller; an SR gateway, wherein the SR gateway includes: an advertisement unit which advertises, when path information of the IP network and an SID of a VRF are received from the VRF, an SR policy including the information of VRF to an ED of an NLRI and an SID of the SR gateway to the controller, and the controller includes: a matching unit which matches the VRF and the SR gateway; an identification unit which identifies, by referring to a PFCP session, a UPF and a gNB corresponding to the IP network to which the VRF is connected; and an advertisement unit which advertises path information of the UPF and an SID of the SR gateway to a VRF corresponding to the gNB identified by the identification unit.

Abstract: Provided is a communication system including: a controller; and an SR gateway which converts an SRv6-compliant packet received from an IP network into a GTP-U-compliant packet. The SR gateway includes a notification unit which notifies the controller, and a router connected to an IP network, of a route including an IP prefix including an address of a reachable gNB in NLRI and an SID of the SR gateway in a BGP attribute, and the controller includes a storage unit which stores an IP prefix including the address of the gNB, and a SID of the SR gateway, in association with each other, and an advertisement unit which searches the storage unit by using, as a key, an address of a gNB included in a UE session information in SMF notified when UE is attached, and when a match is found, advertises route information of the UE to the router.

Abstract: A communication system is provided that comprises a MEC site that is connected to an SRv6 network arranged between a mobile network and Internet and that has a controller and a plurality of edge hosts; and a GC that manages a plurality of the MEC sites, wherein the controller includes an allocation unit that allocates a prefix to each of the plurality of edge hosts from an IPv6 prefix allocated by the GC; and a reporting unit that reports to the GC an allocation result by the allocation unit, wherein each of the plurality of edge hosts includes a virtual switch unit that advertises to the SRv6 network a prefix allocated by the allocation unit; and a BGP speaker unit.
