摘要： A system and method are described for gathering statistics about packets. The method includes determining at a service manager statistics that are to be gathered for a flow and sending instructions to a forwarding agent from the service manager detailing how to gather statistics for the flow. The forwarding agent is implemented on a network device and the forwarding agent is operative to receive statistics gathering instructions for a flow from the service manager. A report is received at the service manager of statistics gathered at the forwarding agent according to the instructions sent by the service manager.

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 controlling access to a server. Instructions are sent to a forwarding agent that instruct the forwarding agent to forward packets to a service manager from clients attempting to establish a client connection to the server. A client connection is established with the client. A server connection is established from the service manager to the server and data is transferred from the server connection to the client connection.

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 network is disclosed that includes a first tier of forwarding agents connected to a first tier of network devices. A second tier of forwarding agents is connected to a second tier of network devices. A service manager is configured to receive a packet from one of the forwarding agents; determine the tier of the forwarding agent; and send an instruction to the forwarding agent directing the forwarding agent to forward the packet to a network device connected to the tier of forwarding agents that includes the forwarding agent.
