ABSTRACT:
A method and device for controlling the transmission across a data link is disclosed. Link Layer protocol formatting in a variation on a "sliding window" protocol is implemented. In data communication equipment, a protocol controller device is described, coupling a first input/output means, for coupling to a local data terminal equipment, to a second input/output means, for coupling said local data terminal equipment to a communication link, comprising: first porting means for transferring information in to and out from said first input/output means; second porting means for transferring said information to and from said second input/output means; switching means coupled to said first porting means for controlling an input/output information transfer path through said porting means; information holding means, coupled to said first porting means and to said second porting means, for pipelining said information through said device; and controlling means, coupled to said holding means and said second porting means, for protocol formatting of said information. The present invention includes a method for controlling data transmission using an open systems interconnection model, comprising: providing link layer sliding window protocol formatting of information to be transmitted such that said protocol provides transmission error control; and providing link layer sliding window protocol formatting of information to be transmitted such that said protocol provides transmission flow control and fully decoded control information.
