    Abstract: In one embodiment, Segment Routing Internet Protocol Version 6 (SRv6) micro segments (“uSIDs”) are included in destination addresses, and possibly in other Segment Identifiers (“SIDs”), of packets transported through a network, and invoking corresponding network behavior, including, but not limited to, realization of corresponding network slices. In one embodiment, network nodes are configured to perform differential network slice realization functionality based on values slice-representative value(s) provided by global and/or local uSIDs of packets. This configuration may be defined by a controller in the network and/or routing protocol advertisements. Responsive to a received packet, a network node identifies and performs the corresponding network slice realization functionality based on slice-representative value(s) provided by one or more global and/or local uSIDs of the destination address of the received packet. Various encodings within an IPv6 Destination Address of the encapsulating packet are disclosed.

    Abstract: In one embodiment, a network comprises a first forwarding domain using a first data plane forwarding protocol and a second forwarding domain using a second data plane forwarding protocol different than the first data forwarding plane forwarding protocol. The first forwarding domain includes a first path node and a particular border node. The second forwarding domain includes a second path node and the particular border node. The particular border node performs Segment Routing or other protocol interworking between the different data plane forwarding domains, such as for transporting packets through a different forwarding domain or translating a packet to use a different data forwarding protocol. These forwarding domains typically include Segment Routing (SR) and SR-Multiprotocol Label Switching (SR-MPLS). Paths through the network are determined by a Path Computation Engine and/or based on route advertisements such associated with Binding Segment Identifiers (BSIDs) (e.g., labels, Internet Protocol version 6 addresses).

    Abstract: Aspects described herein include a method for use with a software-defined network controller, as well as an associated computer program product and system. The method comprises assigning a segment identifier to an endpoint node within a destination domain of a plurality of domains. Adjacent domains of the plurality of domains are connected via a respective set of two or more domain border routers. The method further comprises assigning a respective segment identifier to each domain. Each domain border router advertises the segment identifiers of the respective two adjacent domains. The method further comprises, responsive to a request from a headend node within a source domain of the plurality of domains, computing a path from the headend node to the endpoint node. The path includes (i) the segment identifiers of any domains between the headend node and the endpoint node, and (ii) the segment identifier of the endpoint node.

    Abstract: A method is disclosed for use by a network element coupled with an optical transport network. The method comprises calculating an optical path from a first packet-terminated optical interface of the network element to a second packet-terminated optical interface of a destination network element coupled with the optical transport network, and signaling the optical transport network to create the optical path. The method further comprises creating an Ethernet interface corresponding to the first packet-terminated optical interface, and adding the Ethernet interface to an Ethernet bundle interface. The method further comprises communicating across the optical path using addressing of the Ethernet bundle interface.
