Embodiment Construction

[0028] A communication device or router according to the invention comprises assigning means for assigning a sub-prefix to at least some of the communication devices connected to it.

[0029] figure 2 It is explained how to assign sub-prefixes according to the present invention.

[0030] The initial prefix P is assigned to the first communication device by manual configuration or any other means (this process is outside the scope of this patent application).

[0031] This first device then assigns the sub-prefix SP to at least a subset of the devices it is connected to 1 . The sub-prefix SP 1 Include prefixes P and N 1 part. The N 1 Part is a unique identifier about the device: it distinguishes the devices from each other within this subset of connected devices.

[0032] According to the present invention, the N 1 The size of the section (ie number of bits) depends on the number of devices on said subset of connected devices that have to be assigned a sub-prefix. If ...

Abstract

A communication equipment for an Internet Protocol communication network including a set of interfaces each connected to one or more other communication equipments and having means for receiving an address prefix from a first other communication equipment. It further includes allocation means for allocating to at least a portion of the other communication equipments to which the first other equipment does not belong a sub-prefix formed of the address prefix concatenated with an individual identifier whose length depends on the total number of other communication equipments.

Description

[0001] Cross References to Related Applications [0002] This application is based on French patent application 0450185 filed February 2, 2004, the entire disclosure of which is hereby incorporated by reference and claims priority under 35 U.S.C. §119. technical field [0003] The present invention relates to an Internet protocol type communication network, precisely a communication network based on IPv6 (Internet Protocol-version 6) protocol stack. The invention specifically relates to the automatic configuration of such networks. Background technique [0004] This type of network includes a group of devices, often referred to as "routers," whose role is to route data traffic between senders and destinations. Each network device has one or more interfaces, each interface is used to communicate with one or more other network devices. [0005] in the attached figure 1 , device R A1 With two interfaces I A1 and I A2 . Interface I A2 for use with a single device R D Th...
