Abstract

System for access to an application distributed over a network of nodes deployed on a communication architecture (A), by a client (C) connected to this architecture. It comprises a server (S) having means for providing on the request of the client information about a set of nodes of the network (Np) taking into account the topology of the network within the communication architecture. It furthermore comprises at least one relay device (R) able to receive the information and at least one mediation device (M) suitable for establishing communications between the client (C) and at least some of the nodes of the set which are determined on the basis of the information provided by the relay device or devices (R).

Claims

1. A system for accessing an application distributed across a network of nodes deployed on a communication architecture, by a client connected to said architecture, comprising:

a server in accordance with the ALTO standard, configured to provide, upon a client'"'"'s request, information about a set of nodes of a network taking into account said network'"'"'s topology within a communication architecture,

said information is constituted by associations between node identifiers and cost;

at least one relay device configured to receive and transmit said information; and

at least one mediation device configured to establish communications between said client and at least some nodes of said set of nodes, the nodes of said set of nodes determined from said information transmitted by the at least one relay device.

2. The system according to claim 1, comprising at least one processing device implementing one of said at least one relay devices and one of said mediation devices.

3. The system according to claim 1, wherein said client transmits said request to said server by means of a client in accordance with ALTO specifications.

4. The system according to claim 1, wherein said information forms an ordered list of node identifiers.

5. The system according to claim 1, wherein said mediation device possesses a cache function for the data transmitted to said application client.

6. A method for accessing an application distributed across a network of nodes deployed on a communication architecture, by a client connected to said architecture, comprising:

a step of a client transmitting a request to a server in accordance with the ALTO standard, which provides, in response, information about a set of nodes of a network taking into account the topology of said network within a communication architecture,

wherein said information is constituted by associations between node identifiers and cost, and

said information is transmitted to at least one relay device; and

a step of establishing communications between said client and at least some nodes of said set of nodes, the nodes of said set of nodes determined based on said information transmitted by the at least one relay device.

7. A non-transitory computer readable storage medium, embodying a computer program comprising means for carrying out the steps of the method according to claim 6, whenever the computer program is implemented by one or more data processing equipment.
