Ring Topology
3. Why It Shines (and Struggles) in Local Environments
Generally speaking, ring topology is more commonly associated with Local Area Networks (LANs). Why? Well, ring topology works best in smaller, more controlled environments. In a LAN, the distances between devices are shorter, which means less signal degradation and faster data transmission. Plus, managing a ring network is simpler when all the devices are located in the same physical space.
However, it is worth noting that Token Ring, a specific implementation of ring topology, was once a player in LAN environments, particularly in the 1980s and 1990s. In Token Ring, a special packet called a “token” circulates around the ring. A device can only transmit data if it possesses the token, which helps prevent collisions and ensures fair access to the network.
But, like many tech trends from the past, Token Ring has largely been replaced by Ethernet, a more flexible and scalable technology. Ethernet, with its star topology and collision detection mechanisms, proved to be a better fit for the ever-increasing demands of modern networks. So, while ring topology, and Token Ring in particular, has historical significance in LANs, it’s not as prevalent today.
Think of it this way: ring topology is like a classic car. It’s got its charms, and it worked well in its day, but it’s not quite as practical or efficient as a modern vehicle for everyday use. Ethernet, with its higher speeds and greater flexibility, has become the workhorse of most LANs.
