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 (A), by a client (C) connected to said architecture, comprising a server (S) in accordance with the ALTO standard, having means to provide, upon said client'"'"'s request, information about a set of nodes of said network (Np) taking into account said network'"'"'s topology within said communication architecture, and further comprising at least one relay device (R) capable of receiving said information and at least one mediation device (M) adapted to establish communications between said client (C) and at least some of the nodes of said set determined from said information provided by the at least one relay device (R).

2. ) An access system according to the preceding claim, comprising at least one processing device implementing one of said at least one relay device(s) and one of said mediation device(s).

3. ) An access system according to one of the preceding claims, wherein said server complies with the ALTO specifications.

4. ) An access system according to the preceding claim, wherein said client transmits said request to said server by means of a client in accordance with ALTO specifications.

5. ) An access system according to one of the preceding claims, wherein said information forms an ordered list of node identifiers.

6. ) An access system according to one of the claims 1 to 5, wherein said information is constituted by associations between node identifiers and cost(s).

7. ) An access system according to one of the preceding claims, wherein said mediation device (M) possesses a cache function for the data transmitted to said application client (C).

8. ) 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 said client transmitting a request to a server in accordance with the ALTO standard, which provides, in response, information about a set of nodes of said network taking into account the topology of said network within said communication architecture, wherein said information is transmitted to at least one relay device, and comprising a step of establishing communications between said client and at least some of the nodes of said set determined based on said information provided by the at least one relay device.

9. ) A software application comprising means for carrying out the steps of the method according to the preceding claim, whenever it is implemented by one or more data processing devices.
