Abstract: A method for providing an update package to a node in a mesh network comprising a set of nodes and a gateway node arranged to provide access to an update server via a second network. The gateway node collects package information from each set node, including a first node. Each package identifies a respective node and its package version. The gateway node may query the update server based on the package information. The update server may respond to the gateway node with an updated package for the first node. The gateway node broadcasts the updated package into the mesh network as a sequence of mesh messages. Each of a first plurality of nodes of the set may forward the mesh messages to other nodes. The first node stores the mesh messages so as the sequence of mesh messages is received, assemble the updated package.

Abstract: An analysis device for analysing a communication network comprising a plurality of communication devices, the communication network being configured such that transport of packets through the network is provided by the communication devices in the network listening for and relaying packets, the analysis device being configured to: receive a traffic statistics log from a profile device, the traffic statistics log comprising a traffic statistics message from each of the plurality of communication devices, each traffic statistics message comprising data defining at least one reception property of the reception of at least one probe message at the respective communication device; and identify, based on the at least one reception property, at least one restriction point communication device from the plurality of communication devices that is a restriction point in the network.
