Abstract
Abstract In the transfer of information packets in a network the information (7) is transmitted by the sending terminal station (1A) provided with a destination address field (9). The destination address field (9) comprises references or codes of the input lines/output lines or connection lines which are to be used when the information packet is retransmitted from nodes (5) in the network. In the corresponding way each information packet is in a node provided with address information in a return address field (11) indicating the connection line or combined input line/output line on which the information packet arrived to the node (5). Thereby the information packet, in a simple way, is provided with a return address and it may be utilized by the receiving terminal station (1 B ) for instance for the transfer of a receipt message.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
106 words
In a network comprising terminal stations, intermediary nodes, and connection lines connecting each terminal station to an intermediary node, a method of transferring information packets, comprising the steps of: addressing an information packet to an intended recipient terminal or node in a destination address portion of said information packet; transmitting said information packet to and receiving said information packet at an intermediary node other than said intended recipient terminal or node; adding to said information packet an indication of which connecting line said intermediary node received said information packet on; and retransmitting said information packet from said intermediary node toward said intended recipient terminal or node.
Claim 2
Dependent Claim
106 words
In a network comprising terminal stations, intermediary nodes, and connection lines connecting each terminal station to an intermediary node, a method of transferring information packets, comprising the steps of: addressing an information packet to an intended recipient terminal or node in a destination address portion of said information packet; transmitting said information packet to and receiving said information packet at an intermediary node other than said intended recipient terminal or node; adding to said information packet an indication of which connecting line said intermediary node received said information packet on; and retransmitting said information packet from said intermediary node toward said intended recipient terminal or node.
Claim 3
Dependent Claim
115 words
The method of claim 1, wherein said step of adding to said information packet further comprises adding said indication in a field of said information packet designated as a return address portion, and comprising the further steps of: receiving said information packet at and retransmitting said information packet from one or more additional intermediary nodes; and at each intermediary node adding to said information packet in said return address portion an indication of which connection said intermediary node received said information packet on, such that respective indications of respective intermediary nodes are arranged in said return address portion in an order reflecting an order in which said information packet was received at said intermediary nodes.
Claim 4
Dependent Claim
96 words
The method of claim 1 wherein said step of addressing an information packet further comprises designating in said destination address portion of said information packet, for each intermediary node expected to receive said information packet, in an order that reflects an order in which said intermediary nodes are expected to receive said information packet, a respective connection line on which each respective intermediary node is to retransmit said information packet, and wherein said retransmitting step further comprises retransmitting said information packet from each respective intermediary node on said respective connection line designated for that intermediary node.
Claim 5
Dependent Claim
49 words
The method of claim 3 wherein said retransmitting step further comprises first removing from said destination address portion of said information packet a designation for an intermediary node retransmitting said information packet of said respective connection line on which each respective intermediary node is to retransmit said information packet.
Claim 6
Dependent Claim
119 words
A network for transferring an information packet comprising terminal stations, intermediary nodes, and connecting lines connecting each terminal station to an intermediary node, wherein each terminal station comprises: means for addressing said information packet to an intended recipient terminal or node in a destination address portion of an information packet; and means for transmitting said information packet on a connecting line; and each intermediary node comprises: means for receiving said information packet on a connecting line; means for adding to said information packet an indication of which connecting line said intermediary node received said information packet on; and means for retransmitting said information packet from said intermediary node toward said intended recipient terminal or node on a connecting line.
Claim 7
Dependent Claim
119 words
A network for transferring an information packet comprising terminal stations, intermediary nodes, and connecting lines connecting each terminal station to an intermediary node, wherein each terminal station comprises: means for addressing said information packet to an intended recipient terminal or node in a destination address portion of an information packet; and means for transmitting said information packet on a connecting line; and each intermediary node comprises: means for receiving said information packet on a connecting line; means for adding to said information packet an indication of which connecting line said intermediary node received said information packet on; and means for retransmitting said information packet from said intermediary node toward said intended recipient terminal or node on a connecting line.
Claim 8
Dependent Claim
41 words
The apparatus of claim 5, wherein said means for adding appends said indication to the end of a list of indications, in a return address portion of said information packet, of other intermediary nodes that have previously received said information packet.
Claim 9
Dependent Claim
65 words
The apparatus of claim 5 wherein said means for addressing designates in said destination address portion of said information packet, for each intermediary node expected to receive said information packet, in an order that reflects an order in which said intermediary nodes are expected to receive said information packet, a respective connection line on which said respective intermediary node is to retransmit said information packet.
Claim 10
Dependent Claim
31 words
The apparatus of claim 7 wherein said means for retransmitting retransmits said information packet on a connection line designated for said intermediary node in said address portion of said information packet.
Claim 11
Dependent Claim
44 words
The apparatus of claim 8 wherein said means for retransmitting further comprises means for first removing from said destination address portion of said information packet a designation of a connection line designated for said intermediary node in said address portion of said information packet.
