Abstract
A service is applied in a packet switching device to both directions of a flow of packets through the packet switching device, with the application of this Layer-4 to layer-7 service to one direction requiring state information shared from the application of the service to packets traversing in the other direction. The service (e.g. firewall, network address translation) can be applied by different processing complexes which do not share memory; thus, state information is communicated between the processing complexes. When the service is applied by a single processing complex, packets can be directed explicitly to the single processing complex. The inline application of services in a packet switching system typically eliminates the need to change a packet's path through the packet switching system to that through a dedicated application server, and may eliminate the need for a dedicated services card or blade server.
