1. A method for routing a packet from over a network including multiple nodes, said method comprising steps of:

  • receiving a packet from a sender node over said network, wherein said packet is intended for at least one destination node having a plurality of defined characteristics, said plurality of defined characteristics being determinable by said sender node, and wherein said packet includes information on said plurality of defined characteristics;

    said receiving step occurring at said at least one destination node having said plurality of defined characteristics;

    wherein said plurality of defined characteristics is a subset of or a total set of multiple, arbitrary characteristics describing aspects of said multiple nodes in said network;

    discovering a topology of said network based on said total set of multiple arbitrary characteristics, wherein said network couples said sender node, said at least one destination node, and at least one routing node, and wherein said discovering step is performed proactively before said packet is sent from said sender node and before said packet is received at said at least one destination node;

    forwarding to said sender node a routing table including entries based on said particular characteristics of each node in network portions, wherein said routing table is not configured at each routing node; and

    sending a copy of said packet based on said entries in said routing table.
