Method and arrangement for providing a wireless mesh network

摘要

A method and an arrangement for providing a wire-free mesh network are provided. An approval procedure is carried out in situations in which a subscriber who is registering on the mesh network transmits an MAC address which already exists in the mesh network, such that two different subscribers within the mesh network never have identical MAC addresses.

主权项

1. A communication apparatus comprising:
a first node communicatively connectable to a registering communication entity, the first node configured to respond to a registration message received from the registering communication entity by assessing a registering MAC address of the registering communication entity such that: when the registering MAC address is disjoint of MAC addresses reachable via a subnetwork to which the first node is connected, the first node connecting the registering communication entity in a manner of a station of the subnetwork; and when the registering MAC address is not disjoint of the reachable MAC addresses such that the registering MAC address already is reachable via the subnetwork, the first node implementing an approval procedure with the registering communication entity to prevent two different subscribers within the subnetwork from having identical MAC addresses; wherein the approval procedure comprises:
requesting, by the first node, a first item of check information from the registering communication entity by way of a first route between the first node and the registering communication entity formed for facilitating registration of the registering communication entity;requesting, by the first node, a second item of check information from the registering communication entity by way of a second route such that a communication entity already having the registering MAC address in the subnetwork receives a request for the second item of check information to forward to the registering communication entity; the first node checking a correlation of the first item of check information with the second item of check information after the first and second items of check information are received from the registering communication entity; the first node connecting the registering communication entity in the manner of a station of the subnetwork when at least a specific degree of correlation is achieved between the first item of check information and the second item of check information; and the first node rejecting the registering communication entity when the specific degree of correlation is not achieved.
