    9199The first issue is how to add 10GigE (GbE) without a switch using low cost dual port GigE cards. Create a four node loop using [http://www.linuxfoundation.org/collaborate/workgroups/networking/bridge#Bridge_priority Ethernet Bridge]. A simple loop will require a Spanning Tree Protocol, but that cuts a link and introduces one 2-hop route, two 1-hop routes, and three 0-hop routes. If one of the bridges is replaced by a [http://www.linuxfoundation.org/collaborate/workgroups/networking/bonding bonded link] in "mode 0" (round robin) then there are ''effectively'' four 1-hop routes and two 0-hop routes, but no route ''effectively'' takes more than "1-hop" in terms of latency and bandwidth.
