Yes, my go-to reference is: https://www.sciencedirect.com/science/article/abs/pii/0167637786900672
Type 1: customers are blocked after finishing service. Type 2: customers are blocked before starting service (that is, service only starts once we know they can move on). I think this is difficult to generalise in networks, where the way ahead might get filled up during the service time. Type 3: customers repeat their service until the path ahead is clear.
Type 3 blocking might be possible in Ciw. I have never seen a need for it though, but could be explored.
FYI I asked Are there other types of blocking in queueing networks beyond Type I?. No actions needed. Close issue after reading.
