Editing HyperTransport (section)

=== Router or switch bus replacement ===
HyperTransport can also be used as a bus in [[Router (computing)|router]]s and [[Network switch|switches]]. Routers and switches have multiple network interfaces, and must forward data between these ports as fast as possible. For example, a four-port, 1000&nbsp;[[Mbit]]/s [[Ethernet]] router needs a maximum 8000&nbsp;Mbit/s of internal bandwidth (1000&nbsp;Mbit/s × 4 ports × 2 directions)—HyperTransport greatly exceeds the bandwidth this application requires. However a 4 + 1 port 10&nbsp;Gb router would require 100&nbsp;Gbit/s of internal bandwidth. Add to that 802.11ac 8 antennas and the WiGig 60&nbsp;GHz standard (802.11ad) and HyperTransport becomes more feasible (with anywhere between 20 and 24 lanes used for the needed bandwidth).
