Abstract: An apparatus includes first agents configured to transfer transactions using an ordered protocol, as well as second agents configured to transfer transactions using a protocol with no enforced ordering. The apparatus may also include input/output (I/O) interfaces coupled to respective ones of the first agents and configured to enforce the ordered protocol. The apparatus may further include a communication network including a plurality of network switches. A particular one of the network switches may be coupled to at least one other network switch of the plurality. The apparatus may also include a network interface coupled to the second agents, to the I/O interfaces, and to the particular network switch. This network interface may be configured to transfer data transactions between the second agents and the particular network switch, and to transfer data transactions between the I/O interfaces and the particular network switch.
