Re-mapping a location-independent address in a computer network
First Claim
1. A method for changing a location-independent address in a network of nodes, the method comprising:
- a first node in the network sending a first message, wherein the first message is addressed to the location-independent address, wherein a second node hosts an instance of the location-independent address, wherein the first message comprises a request to host an instance of the location-independent address;
the second node receiving the first message; and
the second node sending a response message to the first node, wherein the response message grants permission to the first node to host an instance of the location-independent address;
wherein the location-independent address comprises a role.

Abstract
A system and method for re-mapping location-independent addresses in a computer network. A first node may send a first message addressed to a location-independent address, where the first message comprises a request to host an instance of the location-independent address. A second node with which the location-independent address is associated may receive the first message, possibly after the first message was propagated through a path of intermediate nodes. The second node may send a response message to the first node, where the response message indicates whether the second node is granting permission to the first node to host an instance of the location-independent address. The response message may also specify whether the second node is giving up its own instance of the location-independent address.

27. A system comprising:
-
a network; a plurality of nodes coupled via the network, wherein each node includes a processor and memory; wherein the plurality of nodes includes a first node operable to send a first message, wherein the first message is addressed to a location-independent address, wherein a second node in the plurality of nodes hosts an instance of the location-independent address, wherein the first message comprises a request to host an instance of the location-independent address; wherein the second node is operable to receive the first message and send a response message to the first node, wherein the response message grants permission to the first node to host an instance of the location-independent address; wherein the location independent address comprises a role. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36)
