    摘要： A method includes receiving an indication of at least one detected security issue at a network device. The indication is received at a security manager processor from a security agent. The method includes selecting, via the security manager processor, at least one executable security object responsive to the indication. The security manager processor verifies compatibility between the at least one executable security object, the network device, and communication media. The method also includes sending the at least one executable security object to the network device via the security manager processor to provide a protective security measure to the network device against the at least one detected security issue upon execution of the at least one executable security object.

    摘要： A system and method are disclosed for monitoring communications of an individual in a packet network. A system that incorporates teachings of the present disclosure may include, for example, a network monitor having a communications interface coupled to a packet network, and a controller. The controller can be programmed to receive a request from a third party to monitor communications associated with an individual, convey to the third party information monitored on a group of one or more permanent virtual circuits (PVCs) of the packet network associated with the individual, detect an update in the group of one or more PVCs, determine new set of one or more PVCs associated with the individual, and convey to the third party information monitored from the new set of one or more PVCs.

    摘要： A communications system is described for enforcing a service level agreement for a specified customer on a network. The communications system includes a router to receive at least one packet containing data. A management system is in communication with the router, where the management system provides access control commands to the router for the specified customer based upon an agreed upon codec and an agreed upon packet length. A detection system is in communication with the router. The detection system extracts a codec information and a packet length information from the packet. If the codec matches the agreed upon codec and the packet length matches the agreed upon packet length, then the packet is allowed to proceed. Otherwise the packet is dropped from the network.

    摘要： A deficit round-robin scheduler including a round-robin table configured to store a plurality of cycle link lists, wherein each cycle link list includes a head flow identification (FLID) value identifying a first flow of the cycle link list, and a tail FLID value identifying a last flow of the cycle link list. A flow table is provided having a plurality of flow table entries, wherein each of the flow table entries is associated with a corresponding flow, and therefore has a corresponding FLID value. A packet queue is associated with each flow table entry, wherein each packet queue is capable of storing a plurality of packets. The deficit round-robin scheduler also included an idle cycle register having an idle cycle entry corresponding with each of the cycle link lists, wherein each idle cycle entry identifies the corresponding cycle link list as active or idle.

    摘要： A frame relay data rate RFR for a VoIP call is determined based on a particular packetization time interval TS and its associated sample data size BS for a particular CODEC, a size BHT of at least one of a frame relay header and a frame relay trailer, and a size BIP of an IP header. A number of VoIP calls NUMVOIP that can be supported by a frame relay access link is determined based on a bandwidth of the frame relay access link that is to be allocated to VoIP traffic, and the frame relay data rate RFR. At least one network parameter is determined based on NUMVOIP. Bandwidth in an asynchronous transfer mode (ATM) network is allocated for the VoIP traffic based on the at least one network parameter.

    摘要： A switch queue predictive protocol (SQPP) includes a packet switching system including: a switch fabric having a cross-point switch, and a plurality of line cards, each coupled to the switch fabric. A cross-point buffer is located at each cross-point of the cross-point switch. The switch fabric also includes a plurality of actual available queue space tables (AAQSTs), each identifying the actual queue space available in a row of the cross-point buffers. Each of the line cards includes an input buffer, an output buffer, and a predicted available queue space table (PAQST) identifying predicted queue space available in a corresponding row of the cross-point buffers. Packet information is transmitted from a source line card to the switch fabric only if available queue space is predicted by the corresponding PAQST. The switch fabric uses the AAQST to update the PAQST after packet information is transmitted to a destination line card.
