Equalized network latency for multi-player gaming

A method is provided for equalizing latency among a group of connections that are being used by the same latency-sensitive application, such as for multi-player network gaming. Delay is added to the packet flow in each connection as necessary at the provider edge router connecting the application server to the network. An NMS connected to the provider edge router continuously monitors the round-trip delay of each connection, determines the additional delay of each connection required to equalize the delays, and informs the provider edge router. The provider edge router buffers traffic on each connection for the respective duration as indicated by the NMS. The NMS may also reroute some of the connections over higher latency resources to reduce the amount of buffering required, which provides the additional advantage of using what might otherwise be less used or economically less valued resources.

Data access method in the network system and the network system

According to this data access method to be used in a network system, while the tag information is read out from the tag memory, the data is speculatively read out from the memory unit in the self node device. When the read out tag information shows that the speculatively read out data is not found in any of the cache memories, such speculatively read out data is sent to the processor in the self node device. When the read out tag information shows that the speculatively read out data is found in one of the cache memories, the data existing in such cache memory is acquired and sent to the processor in the self node device and the speculatively readout data is abolished.

Stable and high speed full range laser wavelength tuning with reduced group delay and temperature variation compensation

A fiber-based ring cavity tunable laser is disclosed in this invention that has full range high speed tuning achieved by combining a optical tunable filter with a period comb-shaped filter with central wavelengths anchored on International Telecommunication Union (ITU) grids. By using segments of dispersion managed fibers with predefined segment lengths the group delay differences are also reduced. The temperature sensitivity of optical transmission is also reduced by arranging the longitudinal axis of different segments of the optical fibers to orient with a relative angular difference, e.g., with an angular difference of ninety degrees.
