    摘要： 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.

    摘要： Methods for use in operation with a signaling path between given entities are disclosed. One such method includes: deriving, from signaling messages between the given entities, a negotiated set of attributes of an expected media session between the given entities; inferring, from the signaling messages and from semantics of another protocol underlying a session initial protocol, an inferred set of one or more non-negotiated attributes of the expected media session; during an actual media session negotiated by the given entities, determining whether the negotiated set and the inferred set of one or more non-negotiated attributes correspond to given attributes of the actual media session; and taking an administratively-defined action if the negotiated set and the inferred set of one or more non-negotiated attributes do not correspond to given attributes of the actual media session.

    摘要： A media control system (MCS) enforces media control policies on systems that conform to the relevant protocol specifications (such as SIP and SDP), for example, by interpreting and potentially modifying or destroying the SDP offers embedded in the SIP signaling messages that traverse it. This enables the MCS to exercise control over SIP-associated media sessions without necessarily inserting itself into the media streams themselves. The MCS can enforce media control policies that are based either directly on information that is explicitly contained in SDP message bodies or on secondary information that can be derived from information that is contained in the SDP messages.
