Re: OT: QOS on Signaling Traffic for Mobile operators, SIGTRAN,

Pseudowires as vendors call them are just standardized approach to
doing TDMoIP and all of them suffer from the same issue. The point is
that IP is inheretly asynchronous, while "GSM" requires synch between
BTS's in order to hand over clients between them. When pressed about
these issues, every single vendor will reply with the same answer:
Yeah, it's an issue, but you can use adaptive sync. When pressed more:
Yeah, we know. Use GP$.

Unfortunately, working for Vodafone (Iceland), I know this all too well :-)
