[0056] Dynamic allocation: PCIe switch integrated circuits support dynamic allocation of bandwidth and resources, adjusting the communication rate dynamically based on the communication needs and priorities between devices. This dynamic allocation mechanism ensures the effective utilization of system resources and improves overall performance.

[0057] NTB technology: PCIe switch integrated circuits support NTB technology, allowing direct communication between two or more systems. NTB technology improves data transfer efficiency by configuring endpoint instances to expose the memory range on a remote machine as a base address register (BAR) and supporting features such as direct memory access (DMA).

[0058] Peer-to-Peer communication PCIe switch integrated circuits support peer-to-peer communication, allowing devices to exchange data directly without going through a host. This communication method further improves the efficiency and flexibility of data transmission.
