Problems solved by technology

[0009] An important disadvantage of the hitherto known assignment update messages is that they do not provide for a structured transmission of information by which the representation of multiple assignments of the represented node with respect to (imVerhöltniszu) its proxy nodes is allowed. update at the same time
Furthermore, the hitherto known assignment update messages do not allow an update of the assignment information concerning the represented node assigned to a proxy node different from the proxy node which sent the assignment update message

Embodiment Construction

[0024] figure 1 A fragment of an exemplary implementation of a mesh network MSN is shown, comprising a first mesh edge node MAP1 , a second mesh edge node MAP2 and a third mesh edge node MPP. The mesh edge nodes MAP1, MAP2, and MPP are characterized in that besides connections with other (not shown) mesh nodes, the mesh edge nodes also have Network MSN connection. In this embodiment, the mesh edge nodes MAP1, MAP2, MPP also function as proxy nodes MAP1, MAP2, MPP. The proxy nodes MAP1 , MAP2 , MPP do not necessarily have to be mesh edge nodes MAP1 , MAP2 , MPP.

[0025] Connections that do not belong to the mesh network MSN (more precisely also referred to as “assignments”) are maintained in particular to nodes outside the network, in particular to nodes STA11 , STA12 , STA21 , STA21 , STA22, DEV1, DEV2. The last-mentioned nodes STA11 , STA12 , STA21 , STA22 , DEV1 , DEV2 are not directly part of the mesh network MSN and are therefore also referred to as “external nodes” S...

Abstract

According to the invention it is provided for use according to the standard IEEE? Allocation update messages for 802.11s mesh networks. Advantageously, the assignment update message according to the invention provides the possibility of setting multiple assignments in the assignment update message and thus ensuring simultaneous updating of multiple assignments of the represented node with respect to its proxy nodes (proxy meshes). The inconsistencies that would occur according to the prior art are thus eliminated when only one transmission of the allocation update message is provided per allocation update. The proxy information field according to the present invention includes a flag field of a plurality of flag fields. The marker field advantageously enables a variable, ie, transmitted information-related structuring of the proxy information field, which also includes the possibility of avoiding redundant information in the proxy information field. .

Description

technical field [0001] The invention relates to a method for updating assignments in mesh networks, in particular according to standard IEEE802.11s. Background technique [0002] The standard IEEE 802.11s, still in draft, is a sub-spec of standard 802.11, which regulates the industry standard for wireless network communication. The goal of IEEE 802.11s is to create specifications for establishing wireless networking networks, also known in the art as wireless mesh networks or mesh networks. Mesh networks can be built and configured largely independently. [0003] From the document IEEEEP802.11s / D3.02: "DraftStandardforInformationTechnology–TelecommunicationsandInformationExchangebetweenSystems–LocalandMetropolitanAreaNetworks–SpecificRequirements–Part11:WirelessLANMediumAccessControl(MAC)andPhysicalLayer(PHY)Specifications–Amendment10:MeshNetworkingol), the so-called "Protocol" protocol is known in the Proxy Described in Section 11C.9.5 of said document. The term "ProxyPr...
