摘要： A network switching device includes a macroflow sub-plane that performs packet-based routing in the network switching device and a microflow routing module that performs flow-based routing in the network switching device. The microflow routing module is separable from the network switching device and operates to provide a data packet via a software defined network agent to an SDN controller. The data packet is associated with a first unknown flow on the network switching device. The microflow routing module further operates to receive via the SDN agent a flow-based routing rule from the SDN controller and route the data packet based upon the flow-based routing rule.

摘要： A system and method of managing network connections using a link policy is disclosed. In one form, a network link management system can include a link control logic module operable to alter a first link data rate of a first link operable to communicate network traffic. The network link management system can also include a link manager coupled to the link control logic module. In one form, the link manager can be configured to initiate altering the first link data rate to a second link data rate value in response to a first link rate policy entry of the first link. The network link management system can also include a link rate policy accessible to the link manager and operable to store the link rate policy entry of the first link.
