It was written by Carl Fredrik Hammar who was mentored by -Richard Braun. - - -## Outline - -*libchannel* was intended to be used to cleanly and efficiently -implement *channel* translators that would correspond to character -device files. In other words, translators for input devices, sound, -network and the like. - -There are many cases where one wishes to stack translators over one -another. Take networking as an example, you may wish to have a pseudo -network device that balance traffic over two real devices. - -The problem with stacking translators this way is that it's -inefficient, for every RPC to the balancer a RPC is made to each of -the real devices. Now a RPC isn't really *that* expensive, but in a -more complex example with more layers the overhead of these RPC's makes -such a stacking infeasible. - -However, by using *libchannel* a translator can provide a description -of what it does (i.e. the code and data it uses), which a translator -layered untop can fetch and use directly. Now only strictly required -RPC's needs to be sent. - - -## Result - -By the end of GSoC 2007, *libchannel* had mostly reached the initial -goals. There some code missing, most notably the code for -transferring channels via RPC, but similar code was already present in -*libstore* and can be trivially adapted for *libchannel*. It also -needed more debugging. - -Despite these minor deficiencies, the project was considered a -success, never the less. - - -## Future directions - -However, while *libchannel* matched the original specifications. It's -believed that it's too inflexible to make use of in many specific -cases and that a more general solution is desired. While the -discussion isn't over yet, it seems *libchannel* will become a support -library to implement specialized channel libraries, e.g. *libaudio* -and *libnetwork* or similar. - -So work on *libchannel* will continue, in one form or another. |
