Actually the usual bus protocols allow to send larger number of requests and the interconnect is allowed to answer them 'out of order' (e.g. AMBA AXI or CHI). But you are free to define you onw protocol and its own rules. The LRM states exactly how to do this. One example can be found at https://github.com/Arteris-IP/tlm2-interfaces which defines the extensions and phases for the AXI/ACE and the CHI protocol.

@plafrattTLM2 is built to allow any protocols you like. The "base protocol" was deemed sufficient for most needs; however, TLM2 was designed specifically to allow alternatives. Furthermore, the standard provides mechanisms to keep the cost of adapters/bridges between protocols simulation efficient. [Plug - ignore if you like] The Doulos course on TLM 2.0 <https://www.doulos.com/training/systemc-tlm-20/systemc-modeling-using-tlm-20-online/> investigates the base protocol and then builds up to a module describing custom protocols.
