About VMkernel NICs and vMotion
The VMware VMkernel networking interface provides network connectivity for the host, handling VMware vMotion, traffic management, and fault tolerance. VMware vMotion enables the live migration of running virtual machines from one physical server to another with zero downtime.
TCP/IP vs. Ethernet
Ethernet is a Local Area Network (LAN), while TCP/IP is a protocol suite for internetworking on and between connected LANs. TCP uses a sliding window for flow control.
Benefits of Layering
The division of network protocols and services into layers helps simplify networking protocols by breaking them into smaller, more manageable units and offers greater flexibility for interoperability.
