Problems solved by technology

[0020] Of course, an operator may choose to only provide a reduced view within the ALTO server, but the document draft-ietf-alto-protocol-04.txt warns against this behavior in section 11.1: In this case, the risk is that the ALTO server does not can no longer assume its role and the deployment of the node network is no longer optimal

Embodiment Construction

[0041] figure 2 The view in is a schematic functional view. It has been intentionally simplified to clarify the description of the principles of the invention.

[0042] It shows a communication structure A connected to a client C. Client C is an application client wishing to use an application distributed across nodes N1 , N2 , N3 . . . N50 of the node network Np.

[0043] As mentioned above, these nodes have different characteristics, especially in terms of network topology. Therefore, they may be located in devices connected to communication fabric A through different access methods (Ethernet, Wifi, 3G, LTE, etc.), each with different characteristics in terms of bandwidth, availability, etc., but they It may also be located in very different geographical areas within different operator networks.

[0044] The application client C may be located in the telecommunications terminal T. It may be a mobile phone, laptop, personal digital assistant or any other device that ena...

Abstract

A system for accessing, by a client (C) connected to a communication fabric (A), an application distributed across a network of nodes deployed on the communication fabric. It comprises: a server (S) compliant with the ALTO standard, having means for providing, when requested by said client, information about a set of nodes of said network (NP) by taking into account the topology of said network within the communication structure installation. It also includes at least one relay device (R) capable of receiving said information and adapted to communicate between said client (C) and said information provided by said at least one relay device (R) At least one intermediate device (M) establishing communication between at least some of the group nodes.

Description

technical field [0001] The present invention relates to applications distributed across a network of nodes deployed on a communication fabric. Background technique [0002] These applications include what is known as "peer-to-peer" (or P2P), but also CDN (Content Delivery Network) networks, which consist of computers networked on the Internet and which cooperate with each other to provide content or data (usually large multimedia content) to the user. [0003] Such a network consists of: [0004] - origin servers, where the content is "injected" into the CDN to be replicated; [0005] - storage nodes (whether permanent or not) geographically distributed in the "edge" of the Internet, where said content is replicated; [0006] - A semantic routing mechanism ("name-based routing") that enables a user request for a piece of content to be served by the "nearest" node in a semantic sense. [0007] These distributed applications also include "computing grids," more generally g...
