Subject: [9fans] critique of sockets API
Date: Tue,  9 Jun 2009 14:49:44 -0400	[thread overview]
Message-ID: <Pine.LNX.4.64.0906081807350.385@tank.cs.indiana.edu> (raw)

Interesting read:
http://cacm.acm.org/magazines/2009/6/28495-whither-sockets/fulltext

If I am right, the filesystem based networking interface offered by Plan 9
has the three limitations discussed here:
* performance overhead: app requesting data from a socket typically needs
to perform 2 system calls (select/read or alt/read)
* lack of an "kernel up-call API": which allows the kernel to inform an
app each time network data is available
* hard to implement "multi homing" with support for multiple network
interfaces

Any thoughts/comments?

Thanks,
-Bhanu
