A method for recovering state information of a first tunnel endpoint of a point to point connection between the first tunnel endpoint and a second tunnel endpoint, the state information comprising a first state variable comprising a sequence number for sent messages and a second state variable comprising a sequence number for received messages. The method comprises detecting a crash of the first tunnel endpoint with a backup tunnel endpoint of the first tunnel endpoint, sending, from the backup tunnel endpoint, at least one request message to the second tunnel endpoint, and recovering the first state variable and the second state variable of the first tunnel endpoint based on the state variables present in at least one response message from the second tunnel endpoint.

Recovery of state information of a first tunnel end-point

The present invention related to handling of data units in a node of a communication system. The data units are distributed in a plurality of transmission queues based on priority parameters that associate with the data units. The queues are weighted such that the weight of a queue defines the relative share of resources allocated to said queue in relation to the resources that are to be allocated to the other queues. The assigned weights can be adjusted based on information of the amount of logical connections that associate with the respective queue.
