摘要： A process is performed by a controller in a split-architecture network. The controller monitors congestion of traffic groups across the split-architecture network and executes the process to provide delay based data rate control to alleviate congestion of the traffic groups. The process includes configuring an ingress switch and egress switch for each traffic group to collect delay measurement data for data packets of each traffic group as they arrive at the ingress switch and egress switch. The delay measurement data is received from the ingress switch and egress switch of each traffic group. A check is made whether a minimum data packet delay for any traffic group exceeds a defined threshold value. A throttling rate is calculated for each traffic group in the split-architecture network, in response to the defined threshold value being exceeded.

摘要： A method implemented in a Software Defined Networking (SDN) network for flow table lookup parallelization is disclosed. The SDN network contains at least a SDN controller and at least a forwarding element and the SDN network utilizes a plurality of flow tables to perform lookup for forwarding traffic. The method starts with determining dependency of flow tables within the forwarding element using a set of dependency determination rules. A dependency graph is then constructed based on determined dependency of flow tables. A dependency degree count for each flow table within the forwarding element is determined based on the dependency graph. Based on the dependency degree count determination for each flow table, a plurality of parallel lookup groups (PLGs) for the forwarding element is formed, where each parallel lookup group contains one or more flow tables having a same dependency degree count.

摘要： A controller performs network-wide congestion control in a split architecture network. The controller receives flow statistics from switches for each entity that communicates via the network. The controller chooses a most congested link as a bottleneck link based on a packet loss rate that is derived from the flow statistics and estimated for each entity on each link of the network. The controller identifies a target path in the network that passes through the bottleneck link and carries the most traffic, and calculates a throttling probability for each sharing entity that shares the target path based on the capacity of the bottleneck link, capacity of the first link of the target path, bandwidth consumption and packet loss rate of each sharing entity. The controller then transmits the throttling probability of each sharing entity to the ingress switch of the target path to reduce the congestion on the bottleneck link.

摘要： A system and method for placing inline services having multiple instances in a service provider network. In one implementation, a topology of the service provider network and services to be placed therein are defined, wherein a network node may include a data forwarding functionality and a control plane functionality. Using service chaining policy requirements, the number of service instances, etc. as input, services and their multiple instances are placed within the network such that an overall network metric is optimized for all subscriber data flows.

摘要： A method implemented in a network for placing services at network devices is disclosed. The network contains a plurality of network devices and offers a set of services to subscribers. Subsets of the set of services are included in ordered service chains for subscribers. The method starts with determining a list of bandwidth consumption entities of a service for each service within the set of services, where each bandwidth consumption entity is based on one or more chains of services. Then a weight of each service is calculated based on the list of bandwidth consumption entities of the service and a service with a highest weight within the group of one or more services that have not been placed is selected. The selected service is then placed at a network device based at least partially on calculating bandwidth impacts to the network by the service.
