ABSTRACT:
A router for routing packets in a telecommunication network is provided. The router comprises a plurality of inputs for receiving packets and a common processor coupled to the inputs for processing at least part of the packets i.e. the control packets according to one or more routing protocols. At least one packet marker is coupled between a first plurality of inputs of the plurality of inputs and the common processor. The marker marks at least part of the incoming control packets. The marking is provided according to a receiving rate of control packets that are received at the first plurality of inputs and that are to be processed according to a first routing protocol. The incoming control packets are received at one of the first plurality of inputs and are processed according to the first routing protocol. The marker therefore provides marked control packets. The common processor comprises a discarder for discarding or dropping, before the processing of the control packets, one or more of the marked control packets. The discarding is based upon the kind of marking of the marked control packets and is provided according to predefined rules and conditions.
