collision domain


Also found in: Medical, Wikipedia.

collision domain

A group of nodes in a shared Ethernet network that compete with each other for access. Typically confined within a subnet, if two or more devices attempt to transmit at the exact same time, a collision will occur. In a switched Ethernet environment, each transmitting-receiving pair of nodes is essentially its own collision domain, except that no collision can occur because there is no sharing of bandwidth. See broadcast domain and CSMA/CD.

In a shared-media environment, multiple source collision domains communicating with the same destination or one source collision domain communicating with many destinations--negates the entire switching advantage, because of the way switching works.
3u/D3) defines maximal diameters for a collision domain (equal to the maximal allowed half-duplex network span) in meters:
The sleek, compact design of the AsanteFAST hubs provides unique stackability to 358 ports in a single Fast Ethernet collision domain.
The NuHub, which offers 8 100Base-TX ports, can also be connected to another 100Base-TX switch to provide a maximum of 16 100Base-T ports on the same collision domain at a very cost-effective price-per-port.
The 100/100 Bridge is the industry's first product which allows users to bridge two 100 Mbps segments and extend their Fast Ethernet network beyond the collision domain limitation of 205 meters.
The FastHub 300 Series' Class II design allows customers to scale a solution up to 254 ports within a single collision domain by directly cascading two stacks together and to distribute and connect hubs in separate wiring closets - without requiring a bridge, router or switch.
Each segment becomes an independent 10Mbps collision domain shared by fewer users and network devices.
This represents a total of 358 ports and the largest Fast Ethernet collision domain on the market.
Since both ends of the link can be configured to full duplex, worrying about the collision domains is not necessary, and 10/100 media converters are not needed, unless network administrators see the possibility of downgrading the link speed to 10 Mbps.
