Abstract: The present technology pertains to a group-based network policy using Segment Routing over an IPv6 dataplane (SRv6). After a source application sends a packet, an ingress node can receive the packet, and if the source node is capable, it can identify an application policy and apply it. The ingress node indicates that the policy has been applied by including policy bits in the packet encapsulation. When the packet is received by the egress node, it can determine whether the policy was already applied, and if so, the packet is forward to the destination application. If the egress node determines that the policy has not be applied the destination application can apply the policy. Both the ingress node and egress nodes can learn of source application groups, destination application groups, and applicable policies through communication with aspects of the segment routing fabric.

Abstract: The techniques described herein relate to a method including: generating a first network policy and a second network policy at a forwarding device within a network, wherein the first network policy is applied to a first traffic classification and the second network policy is applied to a second traffic classification; obtaining first traffic from an endpoint device; classifying the first traffic with the first traffic classification; applying, at the forwarding device, the first network policy to the first traffic; obtaining, at the forwarding device, an indication of a network event within the network; obtaining second traffic from the endpoint device; classifying the second traffic with the second traffic classification in response to obtaining the indication of the network event; and applying, at the forwarding device, the second network policy to the second traffic.
