Abstract
A method of metering bandwidth allocation on a server using credits is disclosed. The method may receive a request for data from a client, respond to the request for data and determining if the request for data for the client exceeds a current data allocation credit limit for the client. Using the round trip time, the method may calculate a connection throughput for a client and may increase the current data allocation credit limit for the client if the server has resources to spare, the client is actively using the current pipeline depth allowed and network connection latency and bandwidth indicate a deeper pipeline is necessary for saturation. The method may decrease the current data allocation credit limit for the client if the server does not have resources to spare.
