We are connected to Valencia University that belongs to RedIris, and RedIris |
46 |
connects via Geant to Ablilene. |
47 |
That is my question, why connecting via Internet2(Geant<-->Abilene) we have |
48 |
that low bandwidth?? Any problem with the routing? |
49 |
|
50 |
We have configured the sysctl like this to solve some problems whith the |
51 |
routing as recommended by some gentoo stuff. |
