Abstract: Disclosed is segment routing for load balancing. A network path identification device can receive a first service request identifying a first service. The first service request can originate from a first client device. The network path identification device can select, from a Source Routing (SR) list, a first service node to provide the first service and a first network path to reach the first service node. The SR list can include a set of service nodes that provide the service and one or more network paths to reach each service node from the set of service nodes. The network path identification device can then transmit a response message to the first service request. The response message can identify the first service node and the first network path so that the first client device can use the first network path to request the first service from the first service node.

Abstract: A method is provided in one particular example and may include obtaining routing information for a plurality of Internet Protocol (IP) addresses in a first network that natively supports a first Internet protocol, the routing information for the plurality of IP addresses in the first network further comprising an additional IP address in the first network and an indication that the additional IP address in the first network is to be used as a tunnel endpoint within the first network for receiving data destined to any of the plurality of IP addresses in the first network; and sending data destined to any one of the plurality of IP addresses in the first network to the additional IP address in the first network.

Abstract: A method is provided in one particular example and may include obtaining routing information for a natively supported Internet protocol of a first network that uses a first routing policy; identifying a route with a tunnel endpoint using the routing information, where the tunnel endpoint supports transitioning between a plurality of Internet protocols; generating tunnel information for the route; and sending the route and the tunnel information to a network element in a second network that uses a second routing policy.
