US 7,257,116 B2 · Disabling header compression over point-to-point protocol (PPP)

Abstract

A method and system for manipulating packet header compression parameters, by substituting at least one instruction set associated with a PPP negotiation packet at the PPP layer of a protocol stack, the at least one instruction set for use in establishing a communication protocol and channel between a pair of correspondents. The method includes the steps of a software module coupled to a first correspondent examining all PPP negotiation packets from a second correspondent; the software module determining whether a first instruction set is present in the PPP negotiation packet; the software module discarding said first instruction set and replacing the first instruction set with a second instruction set; and at the second correspondent receiving the second instruction set associated with a communication protocol information.

Dependent claims

A method for disabling header compression of TCP/IP headers during an establishment and configuration of a communication protocol and communication channel between an initiating correspondent and a responding correspondent, said method including the steps of:

an initiating correspondent transmitting at least one PPP negotiation packet having at least one acceptable TCP/IP header compression option type, said option type being associated with a first instruction set for said establishment and configuration of said communication protocol and channel;
a software module coupled to said responding correspondent intercepting and examining said at least one PPP compression request packet before said at least one PPP compression request packet reaches said responding correspondent's PPP layer;
said software module modifying said acceptable option type to an unacceptable option type and transmitting said modified PPP negotiation packet to said responding correspondent's PPP layer;
said responding correspondent's PPP layer receiving said modified PPP negotiation packet and rejecting said unacceptable option type;
said software module receiving said PPP negotiation packet having said unacceptable option type;
and
said software module modifying said unacceptable option type to said acceptable type and transmitting said PPP negotiation packet to said initiating correspondent.
