Abstract: A routing system can provide a Dynamic-Hybrid Forwarding Information Base (DHFIB). A control component of the routing system can build a routing table that includes routing information (e.g., prefixes, addresses, etc.) for use by a first routing component. The routing table can be ordered or ranked based on traffic information from the first routing component. Then, the control component can create the DHFIB from the routing table, wherein the DHFIB is a portion of the routing table and related to the first routing component. As such, the portion of the routing table selected for the DHFIB can be the set of prefixes in the routing table that represent the most frequently routed or most important prefixes in the routing table. Finally, the control component can forward the DHFIB to the first routing component to allow the routing component to route communications.

Abstract: The present invention generally relates to methods of routing packets in a network comprising Autonomous Systems (ASs), next hop determiners for routing packets in such a network, systems for routing packets in such a network, and route indicator feeders for providing modified route indicators. A method of routing packets in such a network may comprise: obtaining route indicators each comprising: an indicator of a network prefix; and an indicator of an AS path for delivering packets to an AS having the network prefix; identifying at least one said route indicator having an AS path indicator comprising a predetermined AS identifier; storing the network prefix indicator of each said identified route indicator; receiving at least one packet having an address indicating a destination; and if the destination address of said packet is within an address range defined by a said stored prefix indicator, transmitting the packet on a non-peering connection to the AS having the predetermined AS identifier.
Abstract translation: 本发明一般涉及在包括自治系统（AS）的网络中路由分组的方法，用于在这样的网络中路由分组的下一跳确定器，用于在这样的网络中路由分组的系统，以及用于提供修改的路由指示符的路由指示器馈线。 在这样的网络中路由分组的方法可以包括：获得路由指示符，每个路由指示符包括：网络前缀的指示符; 以及用于将分组递送到具有网络前缀的AS的AS路径的指示符; 识别至少一个所述路由指示符，其具有包括预定AS标识符的AS路径指示符; 存储每个所述识别的路由指示符的网络前缀指示符; 接收具有指示目的地的地址的至少一个分组; 并且如果所述分组的目的地地址在由所述存储的前缀指示符定义的地址范围内，则在非对等连接上将分组发送到具有预定AS标识符的AS。

Abstract: Dynamic and self-healing optimized traffic rerouting is provided. A system and method are described for determining and implementing optimized traffic routing decision. A route orchestration system monitors network resource performance characteristics information for identifying a traffic redirection triggering event and for determining an optimized traffic control decision based on the network resource performance characteristics information. The decision may include software defined networking (SDN) instructions that may be communicated to one or more network resources (e.g., PE devices, P devices, and/or routers) that may cause traffic to be rerouted the one or more targeted servers. For example, the optimized traffic control decision may be determined to improve load balancing amongst performing servers and other network resources in the network while reducing or minimizing administrative costs. Network resources may include a programmatic component that allows the optimized traffic control decision determined by the route orchestration system to be implemented by the resource.
