Abstract

To provide proxy address neutrality, in particular for mobile server devices, a server application can register its network address with a discovery application. Whenever the server application acquires a new network address, the server application updates the discovery application. A client application providing proxy services for the server application can invoke calls to the server client using the network address for the server application that is currently stored in the client device. If the current network address is invalid, the client application obtains an updated network address from the discovery application.

Claims13

Dependent claims

A method for providing a proxy service for a distributed application comprising at least one client application, at least one server application and at least one discovery application having a stable network address, the method comprising:

distributing the distributed application comprising:
establishing the at least one client application on a first mobile device;
establishing the at least one server application on a second mobile device;
establishing the at least one discovery application on a third device;
and
configuring the at least one client application and the at least one server application with the stable network address of the at least one discovery application;
establishing, by the at least one server application, a server context for at least one service of the at least one server application at the second mobile device;
establishing, by the at least one client application, a client context at the first mobile device as a proxy for the server context at the second mobile device;
performing a remote call from a proxy service of the at least one client application to a service of the at least one server application executing on the second mobile device;
obtaining a network address for a server from the at least one client application;
determining if the network address is valid;
if the network address is not valid, retrieving an updated network address from the at least one discovery application;
and
performing the remote call using the updated network address.

11 more elements

A system for providing proxy address neutrality, comprising:

a discovery application of a distributed application, wherein the discovery application has a stable network address and at least one server application and a client application are each configured with the stable network address of the discovery application;
a server device comprising at least one server processor and an operatively associated server memory, the at least one server processor configured to execute the at least one server application of the distributed application, the at least one server application comprising:
a server context comprising a network address and configured to register the network address with the discovery application;
and
at least one server service;
and
at least one client device comprising at least one client processor and an operatively associated client memory, the at least one client processor configured to execute the client application of the distributed application, the client application comprising:
a client context;
and
at least one proxy service of the at least one server service;
wherein the client context is configured to:
retrieve the network address from the discovery application;
perform a remote call from at least one proxy service to the at least one server service;
obtain a network address for a server of the at least one server service from within the client context;
determine if the network address for the server is valid;
if the network address for the server is not valid, retrieve an updated network address from the discovery application;
and
perform the remote call using the updated network address.
