Previous: The Flow Timeout Parameter
The flow methodology is not only interesting for measurement
applications, it has also been discovered by protocol designers. As
already mentioned in the introduction, flows can be used to accelerate
switching and routing. To ameliorate the effectiveness that ``
flow switching'' has, protocol designers have started developing
special flow-oriented protocols. In the ``IPng'' (Internet Protocol
Next Generation, IPv6) protocol for example e a special field in the
header has been reserved for future flow based applications. Another,
more concrete development is Ipsilons flow management protocol, which
is used to exchange flow-based routing policies between Ipsilon
switches.
