Resource scheduler within a network device
First Claim
1. A security device for processing communication sessions comprising:
- an internal memory;
an engine that performs file-based scanning on network traffic received via communication sessions using the internal memory; and
a resource scheduler module that prevents the communication sessions from timing out by allocating memory from the internal memory so that at least one of the communication sessions is guaranteed to be processed to completion.

Abstract
A network device is described in which a dedicated resource scheduler monitors memory consumption to provide for improved processing of communication sessions. The scheduler maintains a dependency list of communication sessions, and reserves memory for communication sessions as requests for memory are received. The amount of memory reserved is determined based on the amount of memory currently reserved for the communication sessions in the dependency list. The network device may control ongoing communication sessions by way of window manipulation. Communication sessions are processed in a first mode when available memory has not reached a predetermined amount, while communication sessions are processed in a second mode when available memory reaches a predetermined amount.
