Abstract: A communication device, such as a telephone or a personal computer, controls one or more remotely controlled devices solely over a signaling path, without necessarily establishing an audio path, thus eliminating the need for the remotely controlled device, or its controller, to include DTMF detection hardware or software or an RTP stack. The communication device can include authentication information, which the communication device uses to authenticate itself to the remotely controlled device, so a user of the communication device can remotely control the device without necessarily entering additional authentication information, such as a passcode. The remotely controlled device (or a controller that controls the device) can register with an element that detects user interactions, such as keypad button presses, with the communication device. The registration can identify one or more patterns of user input.

Abstract: Multiplexing data from bitstreams is described. Data status is determined for data of each of the bitstreams. Stream numbers are assigned respectively to the bitstreams, and the data of each of the bitstreams is controllably stored in respective memory. A memory buffer of the memory buffers is controllably selected. The data obtained from the memory buffer selected is parsed to provide an output. The controllably selecting and the parsing are repeated to obtain and parse the data stored in at least one other memory buffer of the memory buffers to provide the output. The output is multiplexed data from the bitstreams respectively associated with the memory buffer and the at least one other memory buffer.

Abstract: The invention relates to a method in particular enabling the computer terminal (T_L) of a local network (RES_L), connected to a gateway (PASS_D) of a remote network (RES_D) by an IPsec tunnel in blocking mode, to launch a print job on a printer (E_L) belonging to the local network. To do this, the gateway (PASS_D) stores the correspondence between the public address (AD_1) of the local router (ROUT_L) providing the connection of the terminal to the Internet, and the private address (ad_3) assigned to the terminal (T_L) in the addressing plan of the remote network (RES_D) during the establishment of the tunnel, and sends the print flow to the local router (ROUT_L), which directs it to the local printer (E_L) by a port translation technique.

Abstract: A data communication method able to transfer data well in real time group communication between one and many communication terminals, which has a communication server system repeatedly judge whether or not each receiving side communication terminal can communicate, postpone the transfer of data to the communication terminals when it judges there is a communication terminal which cannot communicate, and newly transfer the data postponed in transfer to all of the receiving side communication terminals when subsequently judging that the communication terminal judged to be unable to communicate is able to communicate and a communication server system and a communication terminal used in the same.

Abstract: An improved system and method for transmitting a multiplexed service stream over an error prone DVB-H channel. Media IP packets are priority labeled. For each time slice burst, the IP packets are grouped based upon the priority labels. MPE-FEC matrices are made for the different priority labels in each time slice burst. RSDT columns are computed such that the average service bit rate does not overshoot the maximum allowed service bit rate, and the protection increases with priority. The ADT and RSDT of the MPE-FEC matrices are then encapsulated into MPE-FEC sections.

Abstract: A communication system carrying out an isochronous transfer, includes a cycle master node and nodes connected with each other through a system bus. The cycle master node sets a cycle time of the isochronous transfer and transfers a cycle start packet onto the system bus for every the cycle time. Each of the nodes transfers an isochronous packet onto the system bus in response to the cycle start packet.

Abstract: Local Interconnect Network message budget calculation error is reduced by utilizing an eight bit time measurement of the sync byte in the message header. The method determines the header budget separately from the data budget, simplifying the required logic. The sync byte reference time is multiplied by the message data size to determine the data budget.

Abstract: Base stations exchange first information with first users over first wireless communication links. A mobile switching center provides mobile telephone service. An Internet access system provides Internet access service. A data system provides a data service. An Ethernet backhaul system uses an Ethernet format to exchange the first information between the first base stations and the mobile switching center, the Internet access system, and the data system. A second base station exchanges second information with second users over second wireless communication links. A first interface is exchanges the second information with the second base station. A second interface exchanges the second information with the first interface over a cable television distribution network. The Ethernet backhaul system uses the Ethernet format to exchange the second information between the second interface and the mobile switching center, the Internet access system, and the data system.

Abstract: A system for aggregating packet in a Medium Access control layer of a router to improve effective bandwidth of transmission over a network. The system begins by receiving Medium Access Control Service Data Unit packets in a Medium Access Control unit of a router wherein each of the Medium Access Control Service Data Unit packets are addressed to different receivers. The Medium Access Control Service Data Unit packets are then aggregated into one Medium Access Control Protocol Data Unit packet. The Medium Access Control Protocol Data Unit packet is then transmitted to said Physical layer of said router for transmission.

Abstract: An interface switch which presents itself as switch to an enterprise fabric formed of the devices from the same manufacturer as the interface switch and that of a host or node to an enterprise fabric from a different manufacturer. This allows each enterprise fabric to remain in a higher performance operating mode. The multiplexing of multiple streams of traffic between the N_ports on the first enterprise fabric and the second enterprise fabric is accomplished by N_port Virtualization. The interface switch can be connected to multiple enterprise fabrics. All control traffic address mappings between virtual and physical addresses may be mediated and translated by the CPU of the interface switch and address mappings for data traffic performed at wire speed. Since the interface switch may preferably be a single conduit between the enterprise fabrics, it is also a good point to enforce perimeter defenses against attacks.

Abstract: A procedure is provided for transmitting packets of variable length, such as AAL2 packets and permitting the transmission of cells such as ATM cells, in time-division circuits such as E1/T1 frames, each divided into a number of time slots, each occupied by an eight-bit byte. The consecutive eight-bit bytes of each packet of variable length and of each cell are located in the slots of consecutive time of at least one group of time slots of the frames. The first eight-bit byte of a packet or a cell is placed at a time slot marked by a pointer occupying a specific time slot of the corresponding group of time slots.

Abstract: Methods and apparatus are provided for applying color based policing at a network node. Committed information rate (CIR) and peak information rate (PIR) buckets used to monitor transmission rates are augmented using CIR overflow and PIR overflow buckets. The CIR and PIR overflow buckets hold tokens provided to CIR and PIR buckets that exceed the associated burst limits. Based on the availability of tokens and the color associated with a received packet, an action can be applied to the packet that promotes the color associated with the packet.

Abstract: A computer system of a federation coupled to a network including a server having an internal address associated with a first subnet and a network abstraction and isolation layer rules-based federation and masquerading (NAIL RBFM) interface that interfaces the server with the network. The NAIL RBFM interface transforms the internal address between the first subnet and a second subnet for intra-federation communications. The NAIL RBFM interface performs transform and inverse transform operations to convert between internal and external addresses of intra-federation network traffic. The operations may be performed on source and destination addresses, and may be configured in any of several manners, such as modifying at least one bit of an address, replacing at least one octet of an IP address, substituting a prefix of an address, replacing an entire address, etc.
