摘要： A network element disposed in a network, where the network element implements a process to manage load distribution across a plurality of network interfaces of the network. The network element redirects traffic flow directed toward the plurality of network interfaces in response to changes in configuration of the plurality of network interfaces, where each traffic flow is a set of protocol data units (PDUs), having an ordered delivery requirement, and where the PDUs are transmitted across the network between a source node and a destination node. The redirection process minimizes data traffic flow disruption when the load distribution is determined using a set of load distribution tables instead of a hashing algorithm.

摘要： A network element acting as a forwarding plane within a software-defined network to reduce negative effects of slow-path packet processing is described. The network element, upon receiving a first packet, determines whether it matches any flow entry within a set of flow tables. When the first packet does not match any flow entry of the set of flow tables, the network element performs a miss procedure including inserting at least a portion of the first packet into a packet miss table of the network element, which is accessed by a controller. The controller may access the packet miss table using a pull mechanism. The miss procedure may also include accessing a configurable default rule table of the network element, which includes rules enabling limited forwarding for those packets that do not match any entry of the set of flow tables.
