A technique manages route optimization for one or more groups of links in a computer network. According to the novel technique, each group or “subgroup” of links comprises one or more links, wherein the group may be configured based on various measures, such as, e.g., connectivity (physical or virtual), policies to be applied, per-prefix, per-application (e.g., Internet traffic or voice over IP, VoIP), geographic location, and/or quality-based (e.g., primary links and secondary/backup links). One or more policies may be defined for the groups of links (i.e., where these group policies are to be applied to the group as a whole), in addition to policies that may be defined for individual to links and/or prefixes. Once the link groups are established, traffic over the groups of links (e.g., routes to reachable address prefixes) may be managed and optimized according to the group policies, such as in accordance with Optimized Edge Routing (OER) techniques. |

1. A method for managing route optimization for a plurality of links in a computer network, the method comprising:
associating each of the plurality of links into one or more of a plurality of groups, each of the plurality of groups having two or more links; defining one or more group policies for each of the plurality of groups, wherein the group policies are to be applied to a respective group as a whole, wherein at least one group policy includes a protocol that determines a selection of a particular group of links over which to route traffic for a particular reachable address prefix; and adjusting routes to reachable address prefixes over the plurality of links according to the one or more group policies, by selecting the particular group of links over which to route traffic for the particular reachable address prefix based on the one or more of the group policies and combining at least one of link performance characteristics or link traffic statistics for links of the particular group of links for use in adjusting routes to reachable address prefixes over the plurality of links. |
