    摘要： A method and system for configuring an optical circuit switch is provided. Configuring includes sampling for demand estimation at buffers of an electrical packet switch that is either directly connected to the optical circuit switch, or is dynamically routed to a physical port that is connected to the optical circuit switch. Configuring is performed based on the demand estimation at a port on the electrical packet switch exceeding a first dynamic threshold. The optical circuit can be released based on the demand estimation at the port on the electrical packet switch receding a second dynamic threshold, and the second dynamic threshold is less than the first dynamic threshold.

    摘要： Embodiments of the present invention provide methods, computer program products, and systems for fulfilling a service chain request. Embodiments of the present invention can be used to collect network data of a plurality of instances of services and connections between the plurality of instances of services and redefine service chains to direct flow to an alternative instance of a service responsive to determining that an instance of a service in a service chain has become inaccessible. Embodiments of the present invention can be used to fulfill a service chain request and avoid one or more instances of services (and/or connections there between) that could cause a delay between transmitting data packets through the service chain.

    摘要： Systems and methods for forwarding data packets in a communications network, the method comprising: providing information included in a first portion of a data packet to a network policy unit, in response to a forwarding device receiving a data packet to be forwarded over one or more network routes; forwarding the data packet according to a flow policy, in response to the forwarding device receiving the flow policy from the network policy unit, wherein the flow policy applied to the data packet by the forwarding device is determined by the network policy unit based on the network policy unit performing an analysis of the information included in the first portion of the data packet in view of policy information provided to the network policy unit.

    摘要： Propagating a flow policy within a software defined network (SDN) includes sending a route path request for a flow from a first forwarding node to an SDN controller of the SDN, receiving route path information specifying a route path for the flow from the SDN controller, and generating, using a processor of the first forwarding node, a control packet including the route path. The control packet is communicated from the first forwarding node to a second forwarding node.
