The exemplary distributed scheduling process may be easily implemented with a low-rate control or by sacrificing the throughput by a small amount. Simulation results also showed that this distributed scheduling process can provide very good delay performance for different traffic patterns. The exemplary distributed scheduling process may therefore be a good candidate large-scale high-speed switching systems. | 2012-05-24 |

In one embodiment, there is presented a system for processing data. The system comprises a first circuit and a memory. The first circuit receives transport packets carrying the data. The memory stores data and comprises at least one context. The first circuit maps the data associated with at least one channel to the at least one context. | 2012-05-24 |
20120128009 | SUBSET CODING FOR COMMUNICATION SYSTEMS - A method for data encoding and associated decoding is based on the concept of batches that allows transmission of a large data file from a source node to multiple destination nodes through communication networks that may employ network coding wherein sparse matrix codes are employed in a network setting. A batch is a set of packets generated by a subset of the input packets using sparse matrix encoder. A sparse matrix encoder can be called repeatedly to generate multiple batches. The batches are generally independent of one another. During the transmission in a communication network, network coding can be applied to packets belonging to the same batch to improve the multicast throughput. A decoder recovers all or at least a fixed fraction of the input packets using received batches. The input packets can be pre-coded using a pre-code before applying sparse matrix codes. The data file can then be reconstructed by further decoding the pre-code. | 2012-05-24 |
20120128010 | MINIMIZING NETWORK LATENCY IN INTERACTIVE INTERNET APPLICATIONS - A method and system that enhances a user's performance while interacting with an interactive internet application such as a Massively Multiplayer Online (MMO) game is provided. The network latency experienced by users participating in the MMO game is minimized by dynamically determining an optimal transmission action for a message generated by the MMO game. In one embodiment, determining the optimal transmission action for a message includes dynamically determining the optimal number of redundant Forward Error Correction (FEC) packets to add to a message prior to transmitting a message to a receiving device. The optimal number of FEC packets is determined based on a wide range of varying network conditions. | 2012-05-24 |
