What protocol is primarily used for communication between NSX components?

The primary protocol used for communication between NSX components is TCP/IP. This protocol suite is fundamental for networking, as it enables reliable and ordered delivery of messages between devices across a network. In the context of NSX, which operates as a virtual networking and security platform, TCP/IP is essential for the communication between various NSX components such as the NSX manager, NSX controllers, and transport nodes.

The TCP protocol, as an integral part of the TCP/IP suite, provides the guarantees that are crucial for the functioning of these components, including error correction, retransmission of lost packets, and ensuring that packets are delivered in the correct sequence. This is particularly important in a complex and dynamic environment like NSX, where configurations and state information need to be consistent and accurately reported among different NSX nodes.

While other protocols like HTTP/HTTPS can also facilitate communication, especially for web-based management interfaces, they rely on TCP as their transport protocol. Thus, TCP/IP remains the foundational layer that enables all such communications in NSX environments.
