Abstract
Abstract This disclosure relates to a system and method for the synchronization of variable-length messages being transmitted between stations of a local area contention network where the messages are made up of a variable number of fixed-length packets. This sytsem is adapted for automatic address assignment of different stations of the network so that the network may be expanded or contracted by adding stations and removing stations respectively. In this manner, a very reliable network is provided in that the failure of any particular station does not interfere with the functioning of the other stations in the network or the network itself. In addition, the system includes provision for associating various server station with a given procedure so that a client station may broadcast a request for a procedure and corresponding server stations will send the response to the client station containing the network identification of the server station. If two or more stations contain the particular procedure called for, the first one to respond to the client station is selected.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
79 words
A station in a communications network including a communications channel for the transmission of packets of information, and a plurality of stations coupled to said channel, said stations being adapted to implement different processes, said a station comprising: means to receive a process name request from another station and to compare said process name with names of processes implemented in said a station; and means to transmit said a station's address to the requesting station when a comparison occurs.
Claim 2
Dependent Claim
79 words
A station in a communications network including a communications channel for the transmission of packets of information, and a plurality of stations coupled to said channel, said stations being adapted to implement different processes, said a station comprising: means to receive a process name request from another station and to compare said process name with names of processes implemented in said a station; and means to transmit said a station's address to the requesting station when a comparison occurs.
Claim 3
Dependent Claim
23 words
A station according to Claim 1 further including: means to receive a request-to-send process from said another station and to execute said process.
Claim 4
Dependent Claim
78 words
A station in a communications network including a communications channel for the transmission of packets of information, and a plurality of stations coupled to said channel, said stations being adapted to implement different processes, said a station comprising: means to transmit to all other stations in the network, a process name request packet; means to receive a packet from another station containing a process name; and means to compare the received process name to the process name requested.
Claim 5
Dependent Claim
78 words
A station in a communications network including a communications channel for the transmission of packets of information, and a plurality of stations coupled to said channel, said stations being adapted to implement different processes, said a station comprising: means to transmit to all other stations in the network, a process name request packet; means to receive a packet from another station containing a process name; and means to compare the received process name to the process name requested.
Claim 6
Dependent Claim
23 words
A station according to Claim 3 further including: means to successively transmit said process name request packet until a name comparison is obtained.
Claim 7
Dependent Claim
20 words
A station according to Claim 4 further including: means to halt said successive transmission after a finite period of time.
Claim 8
Dependent Claim
74 words
In a station in a communications network including a communications channel for the transmission of packets of information, and a plurality of stations coupled to said channel, said stations being adapted to implement different processes, the method comprising: receiving a process name request from another station and comparing said process name with names of processes implemented in said a station; and transmitting said a station's address to the requesting station when a comparison occurs.
Claim 9
Dependent Claim
74 words
In a station in a communications network including a communications channel for the transmission of packets of information, and a plurality of stations coupled to said channel, said stations being adapted to implement different processes, the method comprising: receiving a process name request from another station and comparing said process name with names of processes implemented in said a station; and transmitting said a station's address to the requesting station when a comparison occurs.
Claim 10
Dependent Claim
20 words
A method according to Claim 6 further including: receiving a request-to-send process from said another station and executing said process.
Claim 11
Dependent Claim
72 words
In a station in a communications network including a communications channel for the transmission of packets of information, and a plurality of stations coupled to said channel, said stations being adapted to implement different processes, the method comprising: transmitting to all other stations in the network, a process name request packet; receiving a packet from another station containing a process name; and comparing the received process name to the process name requested.
Claim 12
Dependent Claim
72 words
In a station in a communications network including a communications channel for the transmission of packets of information, and a plurality of stations coupled to said channel, said stations being adapted to implement different processes, the method comprising: transmitting to all other stations in the network, a process name request packet; receiving a packet from another station containing a process name; and comparing the received process name to the process name requested.
Claim 13
Dependent Claim
21 words
A method according to Claim 8 further including: successively transmitting said process name request packet until a name comparison is obtained.
Claim 14
Dependent Claim
18 words
A method according to Claim 9 further including: halting said successive transmission after a finite period of time.
