Patent Images
1. A method for delivering an incoming packet through a performance enhancing proxy network device to a recipient computing system, the performance enhancing proxy network device coupled in a parallel configuration, the method comprising:
- receiving a data packet having a destination IP address, the destination IP address specifying a recipient computing system on a local network;
diverting the data packet to the performance enhancing proxy network device;
receiving the data packet from the performance enhancing proxy network device, the data packet processed by the performance enhancing proxy network device; and
sending the data packet to the recipient computing system over the local network.

Abstract
A performance enhancing proxy network device is configured to operate in a virtual inline mode, in which selected network traffic is redirected to and through the network device by a router using simple routing policies. In this way, the network device can be coupled to the router in series but can still operate as if it were physically connected inline.

13. A method for handling incoming and outgoing data packets in one or more routers, the method comprising:
-
receiving incoming data packets from a wide area network (WAN), at least some of the incoming data packets having a destination IP address specifying a computing system on a local area network;
receiving outgoing data packets from the local area network (LAN), at least some of the outgoing data packets have a destination IP address specifying a computing system over the wide area network;
diverting the incoming data packets and the outgoing data packets to a network device according to a set of rules;
receiving the diverted data packets from the network device, the diverted data packets retaining their destination IP addresses; and
delivering the diverted data packets according to their destination addresses. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A network system for handling incoming and outgoing packets, the system comprising:
-
a local area network coupled to one or more local computing systems;
a connection to a wide area network;
a performance enhancing proxy network device coupled in parallel to the local area network, the performance enhancing proxy network device configured to receive data packets, perform one or more enhancement processing functions on the data packets, and return the processed data packets to the router; and
a router providing a communication interface between the local area network and the wide area network, wherein the router includes a means for redirecting incoming and outgoing data packets from the local area network and the connection to the wide area network to the performance enhancing proxy network device. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28)
