摘要: In one embodiment, ports of a network device are assigned to virtual service domains (VSDs). The ports are coupled to a virtual Ethernet module (VEM) of the network device. Each VSD is associated with one or more virtual service engines (VSEs) in a particular order. Each VSE is configured to apply a particular service to traffic traversing the VSE. Traffic received at a virtual Ethernet module (VEM) of the network device that is destined for a particular VSD, and is received on a port that has not been assigned to the particular VSD, is forwarded to the particular VSD via the one or more VSEs associated with the particular VSD such that the traffic traverses the one or more VSEs in the particular order.

摘要: In one embodiment, layer-2 (L2) ports of a network device may each be assigned to a particular virtual service domain (VSD). One or more virtual service engines (VSEs) may also be assigned in a particular order to each VSD, where each VSE is configured to apply a particular service to traffic traversing the VSE between ingress and egress service ports. Interconnecting the L2 ports and the ingress and egress service ports is an illustrative virtual Ethernet module (VEM), which directs traffic it receives according to rules as follows: a) into a destination VSD via the one or more correspondingly assigned VSEs in the particular order; b) out of a current VSD via the one or more correspondingly assigned VSEs in a reverse order from the particular order; or c) within a current VSD without redirection through a VSE.
