The energy efficient connectionless routing method with simple lookup includes determining a label sequence which will allow the message packet to traverse a plurality of MPLS domains and affixing the label sequence to the header of the message packet. This allows the message packet to traverse a plurality of MPLS domains without requiring a subsequent IP address lookup at every MPLS domain boundary. The energy efficient connectionless routing method with simple lookup is particularly useful for reducing power consumption associated with TCAM operations during IP address lookups. In addition, a Label Sequencing Edge Router is disclosed for performing the method. | 2013-03-28 |
20130077631 | METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING OF THE OBJECT-BASED AUDIO CONTENTS - The present invention relates to a system for transmitting and receiving audio, particularly, to a method and apparatus for transmitting and receiving of object-based audio contents, which packetizes audio objects having the same characteristic. To achieve the above, the present invention includes filtering a plurality of ESs according to common information, adding a packet header to the respective filtered ESs and generate ES packets, aggregating all the generated ES packets and then adding a multi-object packet header to the aggregated ES packets to generate an object packet, and multiplexing the generated object packet, packetizing the multiplexed object packet according to a transmitting media and transmitting the packetized object packet. | 2013-03-28 |
20130077632 | BUFFER CONTROLLER CORRECTING PACKET ORDER FOR CODEC CONVERSION - A buffer controller has a buffer for holding plural sets of data contained in a packet entered from a telecommunications network, a codec converter and a controller. When receiving a packet, the buffer controller has the controller put data, in the packet, in a storage position in the buffer corresponding to the sequence number of the packet, and makes a decision as to whether or not the codec conversion is to be performed. If packets are out of sequence, lost or dropped during communication, the buffer controller can correct the packet order and compensate the packet loss with the minimum delay. | 2013-03-28 |
20130077633 | COMMUNICATION SYSTEM AND ITS DEVICE - A transmission device uses transmission delay time of reciprocation with the terminal and time information of the transmission device to create a correction value of time information of the terminal and transmits it to the terminal. The terminal includes expected arrival time information based on the time information of the terminal and the correction value received from the transmission device in a frame transmitted to the transmission device. The transmission device compares reception time of the frame with the expected arrival time information in the frame. If they match, the time information of the terminal synchronizes with the time information of the transmission device. If they do not match, the transmission device transmits a new correction value to the terminal. The terminal transmits a frame including expected arrival time information using the new correction value to the transmission device. | 2013-03-28 |
20130077634 | Systems and Methods of Providing Outside Plant Transport Gateway - In example embodiments of systems and methods of outside plant transport gateway provided herein, instead of locating the gateway/media converter inside the customer premises, the gateway/media converter is located outside the customer premises and may be configured to provide access/media conversion for multiple homes. In previous systems, the gateway/media converter is located in the customer premises. However, the customer premises must be entered to perform maintenance or other work. Moving the gateway/router outside of the customer premises offers easier maintenance at the gateway level. | 2013-03-28 |
20130077635 | System and Method for Dynamically Configurable Multi-Window Divergent Protocol Bridge - A bridge interfaces a first network protocol and a second network interface protocol. Each of a plurality of mapping windows is defined by corresponding mapping parameters defining a space in the first protocol and defining the mapping window translation rules to the second network protocol. Transaction requests in the first network protocol are selectively associated with the mapping windows. | 2013-03-28 |
20130077636 | Time-Preserved Transmissions In Asynchronous Virtual Machine Replication - The method includes determining a timestamp corresponding to a received data packet associated with the virtual machine and releasing the data packet from a buffer based on the timestamp and a time another data packet is released from the buffer. | 2013-03-28 |
20130077637 | HIGH SPEED FIBRE CHANNEL SWITCH ELEMENT - A high-speed Fibre Channel switch element in a Fibre Channel network is provided. The Fibre Channel switch element includes, a rate select module that allows a port in the Fibre Channel switch element to operate at a rate equal to and/or higher than 10 gigabits per second (“G”). The port may operate at 20 G, 40 G or at a rate greater than 40 G. Also, a cut status is provided for cut-through routing between ports operating at different speed. Plural transmit and receive lines are used for port operation at a rate equal to or higher than 10 G. | 2013-03-28 |

20130077639 | EXPLOITING CLUSTER AWARENESS INFRASTRUCTURE THROUGH INTERNET SOCKET BASED APPLICATIONS - Provided are techniques related generally to computer communication and, more specifically, to techniques that provide legacy applications with access to a cluster infrastructure. A pseudo interface layer provides applications with internet protocol (IP) family sockets access to cluster awareness protocols in a manner that may be transparent to both the application and the cluster awareness layer of a kernel. | 2013-03-28 |
20130077640 | SYSTEM AND METHOD FOR COMMUNICATING OPTICAL SIGNALS VIA COMMUNICATION CABLE MEDIUM - A data communication system is disclosed including a cable medium and modulator adapted to carry data and power between a high speed data source and a high speed data sink. Relatively high speed data (e.g. the TMDS data of an HDMI interface) may be carried on optical waveguides in the cable medium. Relatively low-speed data (e.g., DDC data and clock, and CEC of an HDMI interface) may be carried on a separate set of optical waveguides or wire mediums. The optical waveguides allow for substantially less signal distortion of the high-speed data, thereby allowing the cable medium to achieve much higher lengths without significantly affecting the high-speed signaling. | 2013-03-28 |
