MESSAGE SYNCHRONIZATION OVER A STOCHASTIC NETWORK

摘要

Methods and apparatus to communicate between a local component (210) and a remote component (230), where the local component (210) is connected to the remote component (230) using a non-deterministic communication link (220). A local clock (216) is synchronized with a remote clock (236) to within a maximum offset. A rate message (226) from the remote component (230) is received at the local component (210), where the rate message (226) includes a first time stamp. A data rate is adjusted using the rate message (226) when the time of the local clock (216) substantially matches a time determined using the first time stamp. A data message (222) is sent to the remote component (230) using the adjusted data rate, where the data message (222) includes a second time stamp for use in processing data in the data message (222). In some implementations, the time determined using the first time stamp is also determined using information about a communication link delay and/or a clock offset.
