One other point about the AIPs relative to the HSSI/DSU ; you may not be interested in this feature , but the AIPs implement traffic shaping- ie
You can
set Peak and Average rates and burst size; you could use this to subrate your traffic -should you be in a situation where this is desirable.
While this is true, I would caution the novice that TCP sources don't really benefit from rate shaping and the sort of burst capability you get with VBR. TCP appears to work with the explicit rate control of ABR, but there are some concerns in the research community that it might not work because both TCP and ABR are working the congestion management problem simultaneously and there may be pathological or even common situations where these congestion management schemes conflict or degrade each other. Time will tell. To date, we know that TCP works well with UBR and large buffers. Large is defined by TCP and the path length and works out roughly to twice the bandwidth delay product on the longest path. --Kent - - - - - - - - - - - - - - - - -
