    摘要: An example method includes disengaging a target node from a cluster, where the disengaging comprises: selecting an inheritor; migrating flows from the target node to the inheritor; informing a migration manager that the target node is disengaged from the cluster; and broadcasting to peer nodes of the target node that the target node is replaced by the inheritor. In particular implementations of the present disclosure, the cluster can include a first layer of a network topology including a forwarding engine that implements hash-based packet forwarding; a second layer of the network topology comprising the target node and the inheritor, where the target node and the inheritor implement flow-based packet forwarding; and a third layer including service nodes configured for packet processing in a network.

    摘要: 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.

    摘要: An example method is provided and includes configuring a service appliance to offload network control plane and network data plane operations to a switch; establishing a communication channel between the service appliance and the switch; and communicating control messages between the service appliance and the switch over the communication channel. In more particular embodiment, the method can include communicating data messages between the service appliance and the switch over the communication channel.

    摘要: Methods and apparatuses for automating return traffic redirection to a service appliance by injecting forwarding policies in a packet-forwarding element are disclosed herein. An example method for automating return traffic redirection can include: establishing a communication channel between a service appliance and a packet-forwarding element; and transmitting an out-of-band message over the communication channel to the packet-forwarding element. The message can include a forwarding policy that requests the packet-forwarding element to forward predetermined packets to the service appliance.
