RSTP implementation status

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

Hi all.
I'm interested in RSTP implementation (and maybe in contributing to it).

I read this [] message, and I had a look on the ongoing RSTP project hosted at []. Is this project still running?

I noticed that such a ongoing project is based on rstplib []. By taking a brief look at the code, it seems to me that such a code is based on the obsolete 802.1w specification, while the newest specification for RSTP is contained in 802.1D-2004; and such a specification (beside incorporating compatibility with STP) is radically different from 802.1w (e.g., different set of states on state machines...), and it is not easy to understand the amount of interoperability between the two.

I think that a serious issue in implementing network bridging/routing protocols is to proper validate and testing it. For example, I know that there are companies that offer commercial validation system for network protocol. As some RSTP implementations as been put in the past in the kernel, and STP is already in it, are such implementations have been tested and validated? How?
