    I don't immediately see a reason why the other side (BSC) would have to use a "distinct" port. […]

    I also think this sentence is too generic or not accurate.
    The problem here comes from that fact that we implement this using 1-to-1 SCTP sockets, which may pose some limitations on the IP addresses + local port that can be assigned in several different ASPs.
    If we implemented 1-to-many sockets, we'd internally have 1 socket which means could be shared by several ASPs sharing the local addresses, and find out the ASP based on remote addresses. But since we are creating 1 socket per ASPs, the kernel doesn't allow re-creating another socket with the same IP address + local port (I think even if the local addresses are different, but I'd need to test it).

    So maybe simply documenting this feature may be better than simply writing that the port must be unique.
