RE: Is an xxUA SGP capable of serving multiple SGs

Hello SIGTRAN Community!
   
  Let me reformulate my initial question. 
   
  I am after the following case. Imagine two overlapping sets of SGPs 
  S1 = {SGP1, SGP2, SGP3}, 
  S2 = {SGP2, SGP3, SGP4}, 
  and let's assume set S1 is serving SG1, while set S2 is serving SG2.
   
  Is this situation possible?
   
  I think it would have impacts both on SG as well as ASP implementations. 
  Is it so?
   
  Thank you,
  Joe

  Brian,

Good point. "1 SG supporting multiple networks" is an equally valid way to express the idea.

I nevertheless contend that "multiple SGs in an SGP" is a valid concept. I find it an easy way to conceptualize the
setup that I described below, sort of a mirror image of "multiple ASs in an ASP".

Barry,

I would call that 1 SG supporting multiple networks, not an SGP
belonging to multiple SGs.
