A network aggregator has interconnects with multiple carriers (network operators). These interconnects give them “layer 2” access to the carrier’s network, with bandwidth passing over the aggregator’s network. An aggregator does not have any physical kit in exchanges.
What is aggregation in network architecture?
Network architects can implement aggregation at any of the lowest three layers of the OSI model. Examples of aggregation at layer 1 ( physical layer) include power line (e.g. IEEE 1901) and wireless (e.g. IEEE 802.11) network devices that combine multiple frequency bands.
What is Ethernet link aggregation?
But standard Ethernet link aggregation never chops up the packet and sends the bits over different links. The official IEEE standard for link aggregation used to be called 802.3ad, but is now 802.1AX, as I will explain later. However, several vendors have also developed their own proprietary variants.
