Abstract
A constant-to-variable cache router is situated between a constant bit-rate network and a variable bit-rate network. A monitor within the variable bit-rate network measures the available bit-rate within the variable bit-rate network and communicates the available bit-rate to the constant-to-variable cache router. When data is received from the constant bit-rate network at the constant-to-variable cache router, the constant-to-variable cache router determines if the available bit-rate is large enough to support the delivery of the data from the constant bit-rate network at the constant bit-rate. If not, then the constant-to-variable cache router caches the data and delivers it at a rate dependent on the available bit-rate of the variable bit-rate network.
