What is Electricity metering data exchange : the DLMS/COSEM suite. Part 8-20, Mesh communication profile for neighbourhood networks about?

This part of IEC 62056 specifies a DLMS/COSEM communication profile that can be used in a smart metering system in which the Neighbourhood Networks (NN) are mesh networks. This profile may be considered as an adaptation and extension of the UDP/IP communication profile specified in IEC 62056-9-7:2013. As in that standard, the PHY and MAC layers are out of the Scope. This Technical Specification specifies a number of features essential to the efficient operation of a large scale AMI using mesh NNs. These features include: identification of the DLMS/COSEM client and server participating in an application association (AA) with their system title, so that this identification does not change when the IP address of the server changes, see Clause 6; a mechanism to inform the client of the binding between the server’s system title and its current IP address(es), see 5.5.3; the use of the DLMS/COSEM UDP based transport layer, that allows keeping DLMS/COSEM AAs open for long periods, while the device may leave and join the mesh NN and/or its IP address may change, see 7.2.2; DLMS/COSEM application layer and application process level security features that can be used in a mesh
