    Abstract: A method for monitoring flow attributes at a network node comprises detecting first information indicative of transmission of a packet through the network node. The first information is discernible from information contained within the packet. The method also comprises determining that the packet is not part of an existing flow and generating, in a flow cache memory, a new flow entry corresponding to the packet. The method further comprises receiving second information associated with the transmission of the packet through the network node. The second information is contained in a forwarding information base (FIB) stored in the network node and cannot be discerned from information contained within the packet. The method also comprises writing, in the flow cache memory, at least a portion of the second information to the new flow entry corresponding to the packet.

    Abstract: Systems and methods for providing service virtualization endpoint (SVE) redundancy in a two-node, active-standby form. An active-standby pair of SVEs register with a cloud-centric-network control point (CCN-CP) as a single service node (SN) using a virtual IP address for both a control-plane and a data-plane. At any given time, only the active SVE is a host for the control-plane and the data-plane. When a failover happens, the hosting operation is taken over by the standby SVE, therefore the failover will be transparent to CCN-CP and the SN.

    Abstract: Methods and apparatus are provided for virtual device context (VDC) integration for network services. VDC integration for network services generally includes mapping a virtual switch, physical ports on the network switch assigned to the virtual switch, a service node and a physical port on a service node to share a common VDC associated with a configuration of the virtual switch. In this manner, the VDC concept is extended to the service node and the network may be easily managed, with a network switch and associated service nodes configured through a single processing system on the network switch or service node.
