A system and method relating to techniques to efficiently update data transmissions, and more particularly to a system and method for using patch enabling Web traffic or Web Internet transmissions, using existing infrastructure so that “difference” information can be sent to an application rather than a complete updated data set, therefore increasing the effective bandwidth along the transmission medium / channel. A proxy server tracks previous versions of content being sent to various clients. In the case where this is new data to the requesting client, then the proxy server sends back the most recent version of this data to the client. If the requested data is an updated version of something already stored in cache on the client side (i.e., data already known to be sent to the client), then the proxy server runs a differencing algorithm and generates a binary patch file identifying steps to perform to update the information. If there is no version of the requested information already on server side and client side, then the entire information packet is sent to the client. Both the server and client must be “patch-enabled”.

In an embodiment, an arbiter may implement a deficit-weighted round-robin scheme having a delayed weight-reload mechanism. The delay may be greater than or equal to a ratio of the fabric clock to a slower clock associated with one or more sources that have no transactions but that have unconsumed weights (or another measure of difference in transaction rate). If a transaction is provided from the one or more sources during the delay, the reload of the weights may be prevented. In some embodiments, the arbiter may be augmented to improve usage of the bandwidth on an interface in which some transactions may be limited for a period of time. The arbiter may implement a first pointer that performs round robin arbitration. If the first pointer is indicating a source whose transaction is temporarily blocked, a second pointer may search forward from the current position of the main pointer to locate a non-blocked transaction.
