摘要： A system and method are disclosed for specifying network address translation for a set of packets. A first set of instructions is sent to a forwarding agent specifying criteria for designated packets that are designated to undergo network address translation. A matching packet is received from the forwarding agent that matches the specified criteria. A network address translation scheme is determined for the matching packet. A second set of instructions are sent specifying the network address translation scheme for packets associated with the matching packet.

摘要： A system and method are disclosed for providing a plurality of network services. The method includes receiving at a forwarding agent a plurality of matching instructions corresponding to a specified flow from one or more service managers and storing the plurality of matching instructions on the forwarding agent having a forwarding agent network interface. A packet for the specified flow at the forwarding agent is received on the forwarding agent network interface. A highest service priority matching instruction stored on the forwarding agent is determined. The packet is processed according to the highest priority matching instruction. A next highest service priority matching instruction stored on the forwarding agent is determined and the packet is processed according to the next highest service priority matching instruction.

摘要： A system and method are described for partitioning a network service among a plurality of service managers. The method includes configuring a first service manager to send a first request to a forwarding agent for packets meeting a first criteria and sending the first request to the forwarding agent. A second service manager is configured to send requests to the forwarding agent for packets meeting a second criteria and the second request is sent to the forwarding agent. Packets are checked at the forwarding agent to determine whether the packets meet the first criteria or the second criteria and packets that meet the first criteria are received at the first service manager; and packets that meet the second criteria are received at the second service manager.

摘要： A system and method are disclosed for providing a network service. A first criteria specifying a first set of flows from a first service manager is received at a forwarding agent. The first criteria specifies an expiration time interval. The first criteria is stored on the forwarding agent. A second criteria is received that specifies a second set of flows from a second service manager at the forwarding agent. The second set of flows includes flows that are in the first set of flows and the second criteria is designated as a lower priority criteria. The second criteria is stored on the forwarding agent.

摘要： 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.
