Abstract

Methods and apparatus are provided for wireless network optimization. Wireless network traffic is optimized by receiving redirected traffic based on one or more configuration rules; and applying the redirected traffic to a protocol optimizer that optimizes the wireless network traffic based on one or more optimization rules. A management interface is optionally provided to manage the network optimization appliance. A process monitor is optionally provided to monitor one or more process threads to determine if the process threads have stalled. The process monitor can monitor other components and can be monitored by at least one other component.

First claim

What is claimed is:

1. A method for improving wireless network traffic, comprising:
receiving selectively redirected traffic of a given session at a network appliance from a network router based on one or more configuration rules that selectively redirect network traffic that matches one or more predefined criteria, wherein said given session comprises a plurality of connections
applying said selectively redirected traffic to a protocol optimizer that improves said wireless network traffic based on one or more optimization rules implemented by a plurality of instances of an optimization process on said network appliance, wherein each of said plurality of instances generates a distinct heartbeat signal on said network appliance, wherein a given instance of said optimization process is associated with a corresponding one of said plurality of connections; and
separately monitoring, at said network appliance, each of said distinct heartbeat signals of said plurality of instances of said optimization process running on said network appliance to determine whether one or more of said plurality of instances of said optimization process within said session have failed and to automatically restart a failed optimization process instance.

2. The method of claim 1 , further comprising the step of providing a management interface to manage said network appliance.

3. The method of claim 1 , wherein said configuration rules specify that at least a portion of said wireless network traffic that is processed by said network appliance is marked.

4. The method of claim 1 , wherein said configuration rules specify a given port where said wireless network traffic should be forwarded for network optimization.

5. The method of claim 1 , wherein said selectively redirected traffic comprises a selected subset of wireless network traffic.

6. The method of claim 1 , wherein said monitoring step further comprises the step of monitoring one or more process threads to determine if said process threads have stalled using a process monitor.

7. The method of claim 6 , wherein said process monitor monitors a plurality of additional components and is monitored by at least one other component.
