Definition - What does Auto-Partitioning mean?
Auto-partitioning, in networking, is an Ethernet component used as a safety net to prevent corrupt data transmission and data loss while isolating defective devices, ports, or network lines. When a defect is identified, such as a detached port, data collision, defective wiring or a jammed signal, the faulty element is automatically partitioned to prevent further network corruption.
Techopedia explains Auto-Partitioning
Auto partitioning isolates defective data from all device and network traffic and safeguards systems while defects are corrected. For example, a malfunctioning network interface card (NIC) may be partitioned from all interface and communication sources. Another example is a faulty network line or node.
A prime example of a network malfunction is a collision, which occurs when multiple devices in a network attempt to transmit data simultaneously.
