Abstract
A method for discovering an agent in an IP environment comprising broadcasting router advertisement messages by router, wherein the messages comprise a first data element corresponding to a network prefix which identifies the network visited by a communication device; receiving the messages by the communication device; obtaining, by the communication device, a second data element identifying the agent; and computing an IP address of the agent by the communication device by using the first data element and the second data element.
Claims45
A method of discovering a first network element in a network comprising:
- broadcasting by a second network element advertisement messages, wherein the messages comprise a first data element;
- receiving the messages by a communication device;
- obtaining, by the communication device, a second data element;
- and
- computing an address of the first network element by the communication device by using the first data element and the second data element.
A system for discovering a first network element in a network comprising:
- a second network element for broadcasting advertisement messages, wherein the messages comprise a first data element;
- a communication device for receiving the messages, for obtaining a second data element, and for computing an address of the first network element by using the first data element and the second data element.
A method of discovering an agent in an IP environment, wherein the agent is of a certain type out of a predetermined group of types and the method comprises:
- broadcasting router advertisement messages by access router, wherein such messages include a network prefix;
- receiving the messages by a communication device;
- gaining a suffix identifying the agent from a data element list stored in the communication device, wherein each suffix corresponds to a specific one of the group of types;
- and
- computing an IP address by the communication device by using the prefix and suffix.
A system for discovering an agent in an IP environment, wherein the agent is identified in its network by a suffix and comprises a certain type out of a predetermined group of types, and the network which corresponds to the agent is identified by a prefix, the system comprising:
- an access router for broadcasting router advertisements comprising the prefix;
- and
- a communication device for gaining the suffix from a suffix list stored in it, for receiving router advertisements, and for computing an IP address using the prefix and the suffix, wherein the suffix corresponds to a specific one of the group of agent types.
A method of discovering an agent in an IP environment comprising:
- broadcasting router advertisement messages by access router, wherein such messages include a network prefix and a suffix identifying the agent in its network;
- receiving the messages by a communication device;
- and
- computing the IP address of the agent by the communication device by combining the prefix and the suffix.
A system for discovering an agent in an IP environment, the agent in its network being identified by a suffix, the system comprising:
- an access router for broadcasting router advertisements comprising a network prefix and a suffix identifying the agent in the network;
- and
- a communication device for receiving router advertisements, for identifying the prefix, and for computing the IP address of the agent by combining the prefix and the suffix.
