SYSTEMS AND METHODS FOR MULTI-LEVEL QUALITY OF SERVICE CLASSIFICATION IN AN INTERMEDIARY DEVICE

摘要

The present invention is directed towards systems and methods for providing multi-level classification of a network packet. In some embodiments, network performance may be enhanced and optimized by providing QoS and acceleration engines with packet- or data-specific information. In addition to source and destination IP addresses and port numbers, packet- or data-specific information can include direction of traffic (client to host or server; server or host to client; or both), Virtual LAN (VLAN) ID, source or destination application or associated application, service class, ICA priority, type of service, differentiated service code point (DSCP), or other information. Some or all of this information may be used to classify the network packet at a plurality of layers of a network stack, allowing for deep inspection of the packet and multiple levels of granularity of classification.

主权项

1. A method for providing classification of a packet, the method comprising:
(a) receiving, by a second classifier of a device, a packet classified by a first classifier to have an application identifier of a first predetermined application; (b) classifying, by the second classifier, the packet as corresponding to a second predetermined application; (c) determining, by the second classifier, that the second predetermined application is a more granular classification than the first predetermined application; and (d) modifying, by the second classifier responsive to the determination, the packet to use the second predetermined application as the application identifier instead of the first predetermined application.
