Multicast routing protocol for computer networks

A method for a multi-casting routing protocol for a router including a condition check comprising the steps of:

• providing a network of routers communicably linked using Distance Vector Multicasting Routing Protocol;
• interpreting data at a Distance Vector Multicasting Routing Protocol DVMRP table at a multicast source router and determining a maximum value to reach all destination routers from the multicast source router thereby defining a pseudo-diameter based on the source router location;
• and
• forming a truncated broadcast tree, by incorporating at a receiving router a pseudo-diameter based conditional check for forwarding of copies of the first packet by the receiving router during broadcasting based on the multicast source router location as a condition for packet forwarding.

A method for a multi-casting routing protocol for a router including a condition check comprising the steps of:

• providing a network of routers communicably linked using Distance Vector Multicasting Routing Protocol;
• interpreting data at the Distance Vector Multicasting Routing Protocol DVMRP table at the multicast source router and determining a maximum value to reach only those routers which are connected to hosts with group members from the multicast source router thereby defining a super pseudo-diameter based on the source router location;
• and
• forming a pruned tree by incorporating at a receiving router a super pseudo-diameter based conditional check for further forwarding of packets by the receiving router.

A network of routers having a multi-casting routing protocol comprising:

• a network of routers communicably linked by a Distance Vector Multicasting Routing Protocol DVMRP;
• a Distance Vector Multicasting Routing Protocol DVMRP table electronically stored at a multicast source router, where the table includes a maximum value to reach all destination routers from the multicast source router thereby defining a pseudo-diameter based on the source router location;
• a broadcast tree having a domain defined as the pseudo-diameter, by incorporating at a receiving router a pseudo-diameter based conditional check for forwarding of copies of a first packet by the receiving router during broadcasting based on the source router location as a condition for packet forwarding;
• said Distance Vector Multicasting Routing Protocol DVMRP table at the multicast source router where the table includes a maximum value to reach only those routers which are connected to hosts with group members from the multicast source router thereby defining a super pseudo-diameter based on the source router location;
• and
• a pruned broadcast tree having a domain defined as the super pseudo-diameter based conditional check for further forwarding of packets by the receiving router.
