Controlling access to a host processor in a session border controller

Methods and systems for controlling access to a host processor is disclosed. One exemplary method comprises the steps of receiving a plurality of signaling packets and controlling access to a host processor, via a first and a second path, for at least a portion of the packets in accordance with a bandwidth limit for the respective path. An exemplary system comprises: a host processor; and a traffic manager coupled to the host processor via a first path and a second path. The traffic manager is configured to communicate at least a portion of the packets to the host processor via a selected one of the paths. The traffic manager is further configured to regulate traffic along the first path such that the bandwidth limit of the first path is respected, and to regulate traffic along the second path such that the bandwidth limit of the second path is respected.
