A collision fragment, also known as a “runt” frame, is a frame of fewer than 64 bytes in length.

In computer networks, collision fragments occur in Ethernet networks when multiple devices attempt to send data simultaneously and their signals collide with each other. The collision detection mechanism in Ethernet networks is designed to handle these collisions by using the CSMA/CD (Carrier Sense Multiple Access with Collision Detection) protocol.

When a collision occurs, it is detected by the network interface cards of the devices involved. These devices send a jam signal to ensure that all other devices on the network are aware of the collision and stop transmitting. The network devices then wait for a random backoff time before attempting to retransmit the data.

Collision fragments, or runt frames, are frames that are smaller than the minimum Ethernet frame size of 64 bytes (excluding the preamble and start frame delimiter). These fragments are usually discarded by the receiving device as they may not contain complete and valid data. Runt frames can be the result of collisions, transmission errors, or even intentionally created by attackers for various network attacks.

Handling collision fragments is an important aspect of network performance and reliability. Network devices and protocols are designed to minimize collisions and the resulting runt frames to optimize data transmission. Different techniques such as proper network design, implementing appropriate collision detection mechanisms, and using collision avoidance protocols help in reducing collisions and improving network efficiency.
