1. A method of facilitating subscription among at least two nodes in a distributed network, said method comprising the steps of:
- designating one of the nodes as a publisher node;
designating one of the nodes as a subscriber node; and
recording a path between the subscriber node and the publisher node, the path comprising at least one link between the subscriber node and the publisher node;
said recording step comprising the step of recording each distinct link in the path between the subscriber node and the publisher node;
said recording step comprising recording each node in the path between the subscriber node and the publisher node, one node at a time;
wherein a type of each node in the path is ascertained; and
wherein the nodes belong to a distributed multicast network.

Abstract
Methods and arrangements for facilitating subscription among at least two nodes in a distributed network, involving the designation of one of the nodes as a publisher node, the designation of one of the nodes as a subscriber node, and the recordation of a path between the subscriber node and the publisher node. The path includes at least one link between the subscriber node and the publisher node, and the recordation involves recording each distinct link in the path between the subscriber node and the publisher node.

6. An apparatus for facilitating subscription among at least two nodes in a distributed network, said apparatus comprising:
-
an arrangement for designating one of the nodes as a publisher node;
an arrangement for designating one of the nodes as a subscriber node; and
an arrangement for recording a path between the subscriber node and the publisher node, the path comprising at least one link between the subscriber node and the publisher node;
said recording arrangement being adapted to record each distinct link in the path between the subscriber node and the publisher node;
said recording step comprising recording each node in the path between the subscriber node and the publisher node, one node at a time;
wherein a type of each node in the path is ascertained; and
wherein the nodes belong to a distributed multicast network. - View Dependent Claims (7, 8, 9, 10)

11. A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps for facilitating subscription among at least two nodes in a distributed network, said method comprising the steps of:
-
designating one of the nodes as a publisher node;
designating one of the nodes as a subscriber node; and
recording a path between the subscriber node and the publisher node, the path comprising at least one link between the subscriber node and the publisher node;
said recording step comprising the step of recording each distinct link in the path between the subscriber node and the publisher node;
said recording step comprising recording each node in the path between the subscriber node and the publisher node, one node at a time;
wherein a type of each node in the path is ascertained; and
wherein the nodes belong to a distributed multicast network.
