question about PCEP FSM: OpenWait state

Dears,

 

We participate in a project called CARRIOCAS (www.carriocas.org).

We take part in a group responsible for the Formal Model of PCEP
as well as the test of PCEP implementations.
Our strategy is the automatic generation of test cases based on the formal model.

 

One of our questions consists in identify scenarios that exemplify the following cases:

 

CASE 1 : OpenWait State. The PCEP receives an OPEN message, without errors but "the session characteristics are unacceptable and NON negotiable"

 

CASE 2: OpenWait State. The PCEP receives an OPEN message, without errors but "the session characteristics are unacceptable BUT negotiable" ?

 

For instance, if we receive the OPEN message with parameters "KeepAlive =0" and "DeadTimer > 0" could it be considered an example for CASE 1?

 

We're looking forward to hearing from you,

 

Regards,

Elisangela.

Hi Elisangela,

"Unacceptable" means "values that the receiver is not willing to use on the
session." It does not mean "illegal" or "invalid."

Cheers,
Adrian
