Abstract

Abstract Data packets are delivered through a constellation (11) of nodes (12) to a termination unit (18, 20, 22). The node where a packet leaves the constellation is a terminal node. Each packet includes a routing code. When a node receives a packet, it examines the routing code to determine if that node might be the packet's terminal node. A table look up operation is performed using the routing code as an index to a routing table. The table identifies a link (16) to use in routing the packet away from the node to a neighbor node. The packet is also examined to verify compatibility between packet type and a selected link. When a node concludes that it might be a terminal node for a packet, it evaluates a channel identifier to determine if it is currently serving the party to whom the packet is directed.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 99 words
A method of routing a signal through a switch which serves as one node (12) in a constellation (11) of switching nodes, said method comprising the steps of: receiving a data packet (96) having a routing code (100) therein, said data packet representing at least a portion of said signal; obtaining a link identifier (16) in response to said routing code, said link identifier specifying one of a plurality of communication links useable at said switch in routing said data packet away from said switch; and transmitting said data packet away from said switch over said one communication link.
Claim 2
Independent Claim 199 words
A method of routing a signal through a constellation (11) of switching nodes (12), said signal being delivered between two points that move with respect to said constellation, and said method comprising the steps of: receiving a data packet (96) at a first node of said constellation, said data packet having a routing code (100) and a logical channel identification (LCID) value (102) therein, and said data packet representing at least a portion of said signal; sending said data packet to a second node of said constellation, said second node being identified in response to said routing code; determining (116), at said second node, whether said second node might be a terminal node for said data packet, said determining step being responsive to said routing code; evaluating (134), when said determining step determines that said second node might be said terminal node, said LCID value to determine whether a logical channel identified by said LCID value is served by said second node; and transmitting (148), when said second node does not serve said LCID value, said data packet away from said second node toward a neighbor node over a second communication link determined in response to said LCID value.
Claim 3
Dependent Claim 115 words
A data packet switching node for routing a signal within a constellation (11) of switching nodes (12), said switching node comprising: a receiver (40) configured to receive a data packet having a routing code (100) therein, said data packet representing at least a portion of said signal; means, coupled to said receiver, for obtaining a link identifier (102) in response to said routing code, said link identifier specifying one of a plurality of communication links useable at said switching node in routing said data packet away from said switching node; and a transmitter (42), coupled to said means for obtaining, for transmitting said data packet away from said switching node over said one communication link.
