There is provided a radio base station suitable for a wireless communications network. The radio base station is arranged to request a local IP address from a DHCP server the request including a local port number. The radio base station is further arranged to receive a response from the DHCP server comprising a local IP address, an external IP address and port forwarding information. The radio base station is also arranged to send a service record update to a DNS server, the service record update comprising the service capability information of the radio base station, the external IP address, and the port forwarding information.

Connecting radio base stations via a third party network

A source network node performs routing path selection in a communications network by steps that include acquiring a dynamically changing metric value of at least one of a plurality of data routing paths extending from the source network node to a destination network node to which data is to be routed. A determination is made as to which of the data routing paths the data is to be routed on the basis of the acquired dynamically changing metric value of the at least one data routing path in order to satisfy at least one predetermined routing criterion. Routing of the data from the source network node to the destination node is then controlled to be performed over the determined data routing paths.

Routing path selection based on dynamical metric values

The present invention relates to embodiments of nodes and methods in a node in a data telecommunication network. The method and embodiments thereof enables control of data packet traffic belonging to different access technologies to be sent with the same Quality of Service class over an aggregated encrypted Internet Security tunnel, IPsec tunnel. The received data packets are encrypted and encapsulated as payload in an IP data packet to be sent over an aggregated encrypted IPsec tunnel, which header is marked with an access technology index comprising a code for the identified access technology of the one or more received data packets encrypted and encapsulated as payload in the IPsec tunnel and a hash identifier code enabling enhanced scheduling and routing.

Method for enabling control of data packet flows belonging to different access technologies

The present invention relates to method and arrangements to measure connectivity between Two Way Active Measurement Protocol TWAMP entities comprising a session-server () and session-reflectors (-) in a communication network. The method comprises steps like: Dividing in the session-server (), the session-reflectors (-) into at least one defined group (-) of session-reflectors (----); Transmitting a test session (-) from the session-server () to the session-reflectors (--) by using Source Specific Multicasting, said test session comprising at least one test packet (--)being destined to at least one session-reflector (--) in at least one defined group (-); Replying to the at least one test packet (--) by the at least one session-reflector (--).
