15 Claims

1. A system for adapting to topology changes in a proxy, comprising:

a processor configured to:

intercept a plurality of communications;

match a communication signature for a topology update in a communication of the plurality of communications;

identify topology update information in the communication;

update at least one listener based on the topology update information, comprising to:

add a listener on a port for a new node identified in the topology update information before sending translated topology information to a client, the translated topology information including an address for the listener for communicating with the new node;

translate the topology update information; and

send the translated topology information to the client; and

a memory coupled to the processor and configured to provide the processor with instructions.

2. A system for adapting to topology changes in a proxy, comprising:

a processor configured to:

intercept a plurality of communications;

match a communication signature for a topology update in a communication of the plurality of communications;

identify topology update information in the communication;

update at least one listener based on the topology update information, comprises to:

delete an existing listener for a removed node that is removed from the topology update information;

translate the topology update information;

remove the existing listener before sending the translated topology update information to a client; and

send the translated topology information to the client; and

a memory coupled to the processor and configured to provide the processor with instructions.

3. A system for adapting to topology changes in a proxy, comprising:

a processor configured to:

intercept a plurality of communications, comprising to:

identify a topology connection based on a matching of a communication signature; and

intercept a plurality of topology communications on the topology connection;

provide a data connection separate from the topology connection;

match the communication signature for a topology update in a communication of the plurality of communications;

identify topology update information in the communication;

update at least one listener based on the topology update information;

translate the topology update information;

send translated topology information to a client;

provide the topology communications for the topology connection from an Open Systems Interconnection OSI Layer 4 data agnostic dispatcher to an OSI Layer 7 topology service;

perform the match, identify, update and translate by the OSI Layer 7 topology service; and

provide data communications for the data connection from the OSI Layer 4 data agnostic dispatcher to an OSI Layer 7 data service;

a memory coupled to the processor and configured to provide the processor with instructions.
