paths that have a high

bandwidth-delay product In data communications, the bandwidth-delay product is the product of a data link's capacity (in bits per second) and its round-trip delay time (in seconds). The result, an amount of data measured in bits (or bytes), is equivalent to the maxim ...

. Such protocols are needed because standard TCP does not perform well over paths with high bandwidth-delay products. Tsunami was developed at the Advanced Network Management Laboratory of

. Tsunami effects a file transfer by chunking the file into numbered blocks of 32 kilobyte. Communication between the client and server applications flows over a low bandwidth TCP connection, and the bulk data is transferred over UDP.
