  • Publication number: 20190288941
    Abstract: In one embodiment, segment routing network processing of packets is performed, including using segment routing packet policies and functions providing segment routing processing signaling and packet forwarding efficiencies in a network. A segment routing node signals to another segment routing node using a signaled segment identifier in a segment list of a segment routing packet with the segments left identifying a segment list element above the signaled segment identifier. A downstream segment routing node receives the segment routing packet, obtains this signaled segment identifier, and performs processing of one or more packets based thereon. In one embodiment, a provider edge node replaces its own segment identifier in a received customer packet, with a downstream customer node using the replaced (signaling) segment identifier (of a provider edge node/segment routing function) for accessing a return path through the provider network.

  • Publication number: 20190288873
    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).

  • Publication number: 20190288940
    Abstract: In one embodiment, segment routing network processing of packets is performed on segment routing packets to use engineered segment routing reverse reply paths which provide efficiencies in communicating packets in a network. In one embodiment, a source node selects a segment identifier of a destination node, with the segment identifier specifying a function value of a dynamic return path segment routing function in order to invoke this function on the destination node. The source node then sends a segment routing packet to the destination address of this segment identifier. Reacting to receipt of this packet and the function value of the dynamic return path segment routing function in the destination address or current segment identifier of the packet, a receiving node generates a responding segment routing packet including the segment identifiers from the received packet in reverse traversal order.

  • Patent number: 10285155
    Abstract: Aspects of the disclosed technology provide ways to report User Equipment (UE) device locations in a 5G network for the purpose of redirecting application traffic from proximately located Data Networks (DNs). In one aspect, the disclosed technology encompasses a process for conveying User Equipment (UE) information to an Application Function (AF), the process includes steps for receiving, at an intermediate-User Plane Function (I-UPF) entity, User Equipment (UE) uplink data from a Radio Access Network (RAN), determining if sharing of location information or application information associated with the UE is restricted, and encapsulating first location metadata or application metadata in an SRv6 packet if the sharing of location information or application information is not restricted. Systems and machine-readable media are also provided.

  • Publication number: 20180375764
    Abstract: In one embodiment, a third-party client network access device sends Internet Protocol (IP) encapsulating packets with a predetermined destination address of a node of the network client service provider (NCSP), with these IP encapsulating packets encapsulating original data packets. These IP encapsulating packets are communicated through the ISP network being used by the NCSP in providing its network services. The predetermined destination address, which is typically also a segment identifier, causes network service processing (e.g., according to a corresponding segment routing function) of the received packet by the node of the NCSP. This processing typically includes creating a segment routing packet encapsulating the original packet (extracted from the received IP encapsulating packet) with its segment list(s) being populated with segment identifier(s) according to a current NCSP segment routing policy reflective of a sequence of forwarding and service chaining operations of the NCSP service offering.

  • Publication number: 20180375684
    Abstract: 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).

  • Publication number: 20180375763
    Abstract: In one embodiment, Ethernet Virtual Private Network (EVPN) is implemented using Internet Protocol Version 6 (IPv6) Segment Routing (SRv6) underlay network and SRv6-enhanced Border Gateway Protocol (BGP) signaling. A particular route associated with a particular Internet Protocol Version 6 (IPv6) Segment Routing (SRv6) Segment Identifier (SID) is advertised in a particular route advertisement message of a routing protocol (e.g., BGP). The SID includes a locator of a particular router and a function encoding representing a particular EVPN end function of the particular router, with the particular SID including a routable prefix to the particular router. The particular router receives a particular packet including the particular SID; and in response, the particular router performs the particular EVPN end function on the particular packet. In one embodiment, the particular packet includes a Segment Routing Header (SRH) including the particular SID as the currently active SID.

  • Publication number: 20180375766
    Abstract: In one embodiment, new Segment Routing capabilities are used in the steering of packets through Segment Routing nodes in a network. A Segment List includes a set of one or more Segment List (SL) Groups, each of which identifies one or more Segments contiguously or non-contiguously stored in the Segment List (or stored across multiple Segment Lists) of a Segment Routing packet. Each SL Group typically includes one Segment that is encoded as a Segment Identifier, and may include Segments that are Extended Values. The steering order of SL Groups is not required to be the same order as they are listed in the Segment List, as the value of Segments Left may be increased, remain the same, or decreased (possibly to skip a next SL Group) and possibly based on the result of an evaluation of a conditional expression.
