Self-Routed Layer 4 Packet Network System and Method
First Claim
Patent Images
1. In a multi-node, connection oriented packet data network, a method of routing a label switched path on demand between a transmitting computer at a first node and a receiving computer at a second node comprising:
- the exposing of a single, optimized path right-of-way from the first node to the second node in response to a request by the transmitting computer, where the right-of-way traverses at least one intermediate node;
the building of a label switched path along said right-of-way from the second node to the first node in response to the acceptance of the request by the receiving computer; and
the transmission of data along said label switched path.

Abstract
The embodiment discloses a connection oriented packet network using an MPLS-type label switching technology. The network uses a very fast hardware-oriented self-routing protocol that can expose a path right-of-way and program a connection between a calling and called party at wire speed. The embodiment requires no provisioning and is well suited for mobile and ad-hoc networks. The system and method taught can be applied to other data networks where performance guarantees are important.

7. In a multi-node, connection oriented packet data network, a method of routing a multicast label switched path on demand between a transmitting computer at a first node and at least two receiving computers at a second and at least a third node comprising:
-
the exposing of a single optimized path right-of-way from the first node to the second node and at least the third node in response to a request by the transmitting computer, where the right-of-way traverses at least one intermediate node; the building of a label switched path along said right-of-way from the second node and at least the third node to the first node in response to the acceptance of the request by the receiving computers; and the transmission of data along said label switched path. - View Dependent Claims (8, 9, 10, 11, 12)
