 For the 1st packet within a network session, although the traffic
redirection scheme is different, but the packet flow is similar.
 Traffic redirection bases on Port-profile-to-VSG binding and flow
entry lookup in the Service Data Path (SDP)
 Processing of internet  VMs and Inter-VMs traffic are
normalized. Different firewall policies will be applied to these traffic
strictly based on source/destination attributes defined in the policy

 After VSG has done the policy evaluation against the first packet of
a network section, a flow-entry cache is established in SDP, which
off-loads the processing of the rest of packets to SDP
 The flow-lookup done in SDP would be able to identify the current
state of the flow, thus SDP can process the subsequent packets
based on the actions stored at the flow entry
