Abstract: The claimed subject matter is directed to novel methods and systems for a network topology wherein an Internet Protocol (IP) network is partially integrated and enhanced with a relatively small number of Software Defined Network (SDN)-Openflow (SDN-OF) enabled network devices to provide a resilient network that is able to quickly recover from a network failure and achieves post-recovery load balancing while minimizing cost and complexity. The SDN-OF Controller, or a management node, determines such a minimum set of SDN-OF enabled devices and establishes IP tunnels to route traffic from nodes affected by failure to designated SDN-OF switches and finally to the final destination without looping back to the failed link or node. By combining SDN-OF enabled switches with IP nodes such as routers, a novel network architecture and methods are described herein that allows for ultra-fast and load balancing-aware failure recovery of the data network.

Abstract: A controller having an application optimally routing traffic to balance fluctuating traffic loads in a SDN network. A processor is configured to control the data plane to establish routing through the plurality of routers, wherein the processor is configured to establish hybrid routing comprising both explicit routing and destination-based routing. The processor utilizes a set of traffic matrices representing the fluctuating traffic load over time. A destination-based multi-path routing algorithm is configured to improve load balancing of the traffic load based on the set of representative traffic matrices. The destination based routing is calculated based on linear programming. The processor comprises a traffic categorization algorithm configured to identify a set of key flows, wherein the processor is configured to explicitly route the set of key flows. The processor is configured such that the set of key flows consume a small fraction of a ternary content-addressable memory (TCAM), and such that the set of key flows provide a routing decision for a large portion of the traffic load.

Abstract: A segment based switching architecture with hybrid control providing flow control in software defined networking (SDN). An SDN controller controls top tier macro-flows and virtual segment backbone connections in a network, and an SDN network edge device controls and manages micro-flows that are attached to the SDN network edge device. The SDN network edge device controls and manages the micro-flows locally without using a southbound API. The SDN network edge device learns flow information such as source information and incoming port information for all unknown micro-flows belonging to defined segments, and builds a virtual segment topology database for each segment. The SDN network edge device employs flow computation algorithms and micro-flow management in a distributed fashion. The virtual segment backbone connections are naturally exposed to the SDN controller through provisioning.
