Abstract
A system and method for providing a network service is described. A fragment criteria is sent from a service manager to a forwarding agent that instructs the forwarding agent how to determine whether a received packet fragment at the forwarding agent matches the fragment criteria. A matching packet fragment is received from the forwarding agent at the fragment service manager. The fragment is assembled into a packet at the fragment service manager and in the event that the fragment completes the packet, a flow identifier specifying a flow is determined from the completed packet and completed packet is sent to a service manager that handles the flow specified in the flow identifier.
