摘要： A method is performed by a controller node to support network element (NE) data migration. The controller node is part of a cluster of controller nodes in a software defined networking (SDN) network. The method includes detecting that a peer controller node in a same replication zone as the controller node has failed, where the peer controller node is a master for data associated with an NE and the controller node is a backup for the data associated with the NE, transitioning a state of the NE to a migration state, transferring the data associated with the NE from backup storage (Zb) of the controller node to dead storage (Zd) of the controller node, receiving a request for the data associated with the NE from a requesting controller node, and transferring at least a fragment of the data associated with the NE to the requesting controller node.

摘要： Methods and apparatuses for autonomous relay of statistics from a network device to a network controller of a software-defined networking (SDN) network are described. The network controller is operative to transmit a message including a statistics profile, where the statistics profile includes a type of data to be collected associated with a behavior of a flow at the network device and a set of one or more criteria; where the message causes the network device to transmit a statistics message associated with one or more flows when the one or more flows satisfy at least one criterion from the set of one or more criteria, where the statistics message includes data collected at the network device associated with a behavior of the one or more flows as identified by the type of data to be collected included in the statistics profile.
