Also in the market, Allied Telesis has EPSR or something like that. It

Fortunately, there is hope in this regard. Take a look at ITU G.8032.

There are a number of vendors that are already in the process of
implementing this. It would be good if people find value in it to
"encourage" their particular vendors to implement it as well. This
would help SP's move away from the proprietary ring protection protocols
like: Extreme EAPS, Foundry's MRP, Force10's FRRP, Cisco's REP, etc.
(When you have at least 4 different vendors doing nearly the same thing
in incompatible ways, it's surprising there isn't a standard).
It should be noted that the above is the first "version" of G.8032.
Take a look at p. 13 in that URL for planned enhancement to future
revisions of G.8032.

but that doesn't prevent a network from
running different rings with different vendors, as they all provide
similar performance.
