A method and a mesh node () for enabling communication of packets in a wireless mesh network with multiple mesh nodes. When receiving () an original advertisement message with a Bloom filter initiated by an original gateway (), it is detected that a predetermined maximum fill rate is reached in the received Bloom filter. The mesh node () starts to act as an intermediate gateway and creates a new advertisement message () comprising a new initiated Bloom filter with a reduced fill rate. The new advertisement message is then transmitted () with the new Bloom filter while indicating that the new advertisement message originates from said original gateway ().

Method and mesh node for enabling communication in a wireless mesh network

Using an authentication server to program network elements, such as a network node, in accordance with software-defined networking techniques in order to establish a traffic flow rule for a communication device or user of the communication device. After successfully authenticating a communication device or user, the authentication server and/or network node may use an identifier received at the authentication server in connection with the authentication procedure in order to obtain a traffic flow rule for the communication device. The traffic flow rule may be established at the network node or forwarded to a second network node configured to receive network packets from the communication device. The first identifier may be any one of a user identifier identifying a user, an application identifier identifying an application, and a device identifier unique to the communication device.

Systems and methods for routing traffic originating from a communication device

A method performed by a machine-to-machine, M2M, server for managing communication with a M2M device is disclosed. The method comprising configuring the M2M device with a finite number of predetermined states and predetermined transitions for moving the M2M device into one of its predetermined states, and sending a message to the M2M device for executing at least one of the predetermined transitions.

Management of communication between M2M device and M2M server with finite state transitions created by the M2M device

A method of providing packet routing information comprises: encoding routing information from a source node to one or more destination nodes into a compact representation of set membership; and putting the compact representation of sets into a header of a packet that is to be sent from the source node to the destination node(s). The compact representation may be obtained by: generating d representations of a set of identifiers; generating d candidate compact representations of set membership from the d representations of the identifiers; and selecting one of the candidate compact representation of set membership. The selection may be made on the basis of which of the candidate compact representations has the lowest rate of returning false positives.
