Abstract
Abstract Described is a method for switching Transmission Control Protocol (TCP) data streams for a fast delivery of voice, video, image or data, or a combination thereof, from one (or more) system(s) to one (or more) other system(s) based on inventor's TCP switching design. The proposed TCP switching system further provides for the consolidation of multiple data protocols in the conventional five-layer stack of Internet protocols, namely, Physical (layer 1), Data Link (layer 2), Network (layer 3), Transport (layer 4), and Application (layer 5). In this patent, the organization of this modified TCP, called the Fast TCP protocol, and the algorithm for establishing communications between any two or more end-systems through any number of intermediate TCP switches, called the Fast TCP switches, are described. The method of TCP switching is installed in the end-systems and intermediate Fast TCP switches to provide medium-independent communications. The medium of communication can be any medium such as copper, fiber or radio.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
187 words
A method for transmitting data, voice, and video between a source and a remote station wherein data/packets are transmitted using a modified/Switched/Fast Transport Control Protocol (TCP), the method comprising: transmitting a packet to a remote station using said Fast TCP wherein said packet comprises: at least one option which comprises three fields, a Kind field which defines the type of option, a Length field which defines the total length of said at least one option in octets, and a Size/Value field which defines the contents of said at least one option using at least one content identifier which comprises of: a fixed or variable length segment/packet size indicator, a Path Identification Number (PIN), and a Channel Identification Number (CIN) for identifying virtual circuits VCSCs) between systems or nodes, a packet flow control parameter, or a network management parameter which can include packet checksum parameters, wherein each field is a minimum of one octet, said fields are arranged in a predefined manner in the TCP option field, and said at least one option ends on the octet boundary, and receiving and processing said packet at said remote station.
Claim 2
Independent Claim
187 words
A method for transmitting data, voice, and video between a source and a remote station wherein data/packets are transmitted using a modified/Switched/Fast Transport Control Protocol (TCP), the method comprising: transmitting a packet to a remote station using said Fast TCP wherein said packet comprises: at least one option which comprises three fields, a Kind field which defines the type of option, a Length field which defines the total length of said at least one option in octets, and a Size/Value field which defines the contents of said at least one option using at least one content identifier which comprises of: a fixed or variable length segment/packet size indicator, a Path Identification Number (PIN), and a Channel Identification Number (CIN) for identifying virtual circuits VCSCs) between systems or nodes, a packet flow control parameter, or a network management parameter which can include packet checksum parameters, wherein each field is a minimum of one octet, said fields are arranged in a predefined manner in the TCP option field, and said at least one option ends on the octet boundary, and receiving and processing said packet at said remote station.
Claim 3
Dependent Claim
100 words
A method as defined in claim 1 further including (a) broadcasting system look-up or address resolution messages of Fast TCP packets through all system ports or interfaces during system start up wherein said packets comprise: interface addresses, system IP addresses, values for setting up VCS with adjacent systems, VC bandwidths or message delivery priorities, corresponding station interface and IP addresses, and/or acknowledgment messages comprising corresponding source VC identifiers and bandwidth values, (b) completing a three-way VC set up message exchange, and (c) setting up access tables wherein said access tables are used to transmit and receive data/packets on the VCS.
Claim 4
Dependent Claim
32 words
A method for transmitting data using the Fast TCP protocol as defined in claim 1 wherein the Fast TCP is compatible with conventional protocols and has the capability of using IPV6 addresses.
