I will use the rfc4666 to have a deep looking. From your comment, DE mode IPSP A IPSP B ASPUP---------------> <--------------ASPUP ASK ASPAC----------------> <---------------ASPAC ACK after the message exchange,IPSP B will consider the IPSP A is ready to receive DATA and it's active for some AS. But IPSP A will treat IPSP B as down?there will be 1 direction message flow? br muare On 6/4/07, ZHOU Minggang <[email protected]> wrote: Hello muare, As per rfc4666(rfc3332 is obsolete) said,: When using DE mode, the management of the connection in the two directions is considered independent, it could happen that only one of the two directions is activated or closed, while the other remains in the same state as it was. When using SE mode, only the activation phase (ASPTM) is independent for each of the two directions. In this case, it could happen that the sending of the ASPSM from IPSP-A to IPSP-B could have an effect in the whole communication. Therefore, if you want to two side independent, you should use DE mode.

But there is not enough info about belows: 1) under which situation,the IPSP DE will be used other than SE mode. 2) Or,the different advantage for DE and SE Thanks muare _______________________________________________ Sigtran mailing list [email protected] https://www1.ietf.org/mailman/listinfo/sigtran
