Now this starts to get even more interesting!
We could use MT-based routers (with fast CPUs) to provide resilience for our 100Mbps or Gigabit Ethernet laser links - most people currently use Spanning Tree or Rapid Spanning Tree, which only uses one of the two links "live":
Using EOIP, it should be possible to use both when they are both up (most of the time) and one when the other is down.
Question: Assuming a 3-port router, with one to the user's network, and the other 2 to the resilient "transmission links" (these are just normal ethernet connections, but connected to transparent laser links), what CPU speed is needed (roughly) to make this work?
user network ------ router ======== router ------ user network
where the '===' are 2 parallel ethernet paths over laser links, either 100Mbps (200Mbps aggregate) or 1000Mbps (2Gbps aggregate).
For many users these are LAN-LAN connections, and they seriously DO use the full bandwidths -
(obvious point well understood: there is no 2Gbps interface, so parallel Gigabit links would need 2 separate user ports, or only supply 1Gbps of traffic)
