Hello,Is there an update to the ACM TOCS 2000 Click Modular Router document that includes Click developments accumulated since that document was published 11 years ago? For example, the wiki provides information about an experimental Multi-threaded Click, which contradicts some statements in the tocs00 document. Also, the performance numbers cite a 700Mhz PIII, and hardware has certainly evolved since then.
The tocs00 document focuses on the in-kernel implementation, and suggests that use of the userlevel interface should be regulated to testing. I am curious to know whether the userlevel driver has improved significantly since that document was published, and whether "real" applications that use Click Modular Router do their business in kernel-space or in user-space.
This is significant for me because I am using Click as a harness for a Network Coding Engine (*) my colleagues and I have developed. Although our Network Coding Engine follows a very Click-like architecture, it works independently of Click and integrates with other environments like the OPNET Network Simulation environment. We haven't actively designed our software to run in kernel-space, and we'd like to know if it is inadvisable to generate performance numbers using Click's userlevel engine. If anyone has any docs/reports regarding experience/use/gotchas/etc of userlevel Click as a production platform, that would be great.
I'd be interested to hear your collective thoughts on the future directions for Click too.
Thanks! Armen(*) For more info on Network Coding, see http://en.wikipedia.org/wiki/Network_coding
