Timed packet processing to regulate data transfer between components of a gateway for a constant delay network
In one embodiment, a gateway for a constant delay network identifies a baseband clock that is synchronized by exchanging synchronization messages over a packet switched network. The gateway then generates a strobe by manipulating the identified baseband clock using a custom multiplier that is selected according to transmission variables. The gateway then signals a front end component to process fixed length packets for transfer to a back end component according to the generated strobe, which can reduce or eliminate buffering by the back end component and can improve cable modem operation.
