How vPath Works

Oct 06, 2014
Figure 1. Packet Flow Using vPath


The above figure illustrates the flow of traffic using vPath:

  1. Client sends request to the NetScaler virtual appliance.
  2. The NetScaler virtual appliance encapsulates the client request with a vPath header and sends the updated packet to the server that is selected by the load balancing algorithm.
  3. The VEM (in which the vPath module is embedded) intercepts and decapsulates the packet and forwards it to the server.
  4. Server responds with the required information.
  5. The VEM encapsulates the server response with a vPath header and forwards the packet to the NetScaler virtual appliance.
  6. The NetScaler virtual appliance decapsulates the packet and sends the response to the client.
