Abstract: The present invention is directed towards systems and methods for providing classification of an encrypted network packet for performing QoS and acceleration techniques. Encrypted packets may be classified by a first classifier at a first portion of a network stack of a device as corresponding to a first predetermined application, and an application identifier may be included with the packet. In some embodiments, the packets may be decrypted in an order dependent on a first classification of the encrypted network packet. After decryption, packets may be reclassified as corresponding to a second predetermined application by a second classifier operating at a second portion of a network stack of the device above the first portion. Thus, network performance may be enhanced and optimized by providing QoS and acceleration engines with packet- or data-specific information corresponding to the application, while avoiding inefficiencies due to a lack of prioritization of decryption.

Abstract: The solution of the present invention provides systems and methods for encoding information into an Internet Protocol identification field (IPID) of an IP layer header of a network packet in a manner acceptable to many or all of the network devices that encounter the encoded packet. In one embodiment, the solution described herein encodes the IP identification field of the IPID header with information to be communicated between devices. Appliances may use the encoded IP field as a signal or a means for a low-bandwidth subcarrier of data between the appliances that is transparent to any intervening network equipment. For example, the encoded field may be used to announce or probe the presence of a device, a functionality or capability of device or to indicate a type or speed of a network connection of a port on a device.
