My guess is that it improves throughput by combining like packets into larger packets up to the MTU of the connection, and eliminating the header overhead of the combined packets. I.e. if your application sends 'HELLO' as five packets, each containing one byte, each of those packets has a header which includes the source address, destination address, source and destination ports, protocol, sequence numbers, blah blah blah. If you send the data as one packet containing five bytes, you only send one lot of header information. If the header is, say, 20 bytes long, then sending 1 x (20 + 5) instead of 5 x (20+1) results in far less bandwidth used. Bear in mind that ADSL is presented as IP packets encapsulated in PPP encapsulated in ATM. This trebles the header overhead. By packing ATM packets up to the MTU of the connection, atleast one layer of this wastage can be reduced. Of course, it may be something entirely different. That's just my guess. Nothing is going to improve on the raw bit rate that your telecoms provider is supplying. How this helps downstream traffic, I don't know. Presumably you'd have to have something like this at both ends of the bottlenecked connection. (Or have I missed the boat here?) Jim |
