Aggregaatioverkko

Aggregaatioverkko, often translated as aggregation network, refers to a part of a computer network that aggregates traffic from multiple lower-bandwidth sources into a higher-bandwidth link. These networks are typically found in the access layer or distribution layer of a network hierarchy. Their primary function is to collect data from many individual user devices or smaller network segments and forward it towards the core of the network.

The purpose of an aggregation network is to provide a cost-effective way to manage network traffic. Instead of each individual device or segment requiring a high-bandwidth connection all the way to the core, they connect to an aggregation device. This device then combines their traffic onto a single, more robust link. This reduces the number of high-cost interfaces needed at the core and simplifies network design.

Common devices used in aggregation networks include switches and routers. These devices are capable of handling multiple incoming connections and forwarding the aggregated traffic efficiently. Examples include enterprise networks where access switches aggregate traffic from end-user devices and connect to distribution switches, or telecommunication networks where aggregation points collect traffic from multiple cell towers or customer premises equipment. The design and capacity of an aggregation network are critical for ensuring adequate performance and avoiding bottlenecks.
