Naming conventions and links IDs

When new links are added do not forget to warn GGUS team to have them modifying the links ID in the TTS.

The MTUs in this section are given as the maximum size of packet (IP MTU) or frame (L2 MTU - often ethernet MTU) that can be transmitted without fragmentation.

Responsibilities for links

  • For T0 - T1 link responsibilities are on T1's side.
  • For T1 - T1 link default responsibilities are depicted on the table of T1 - T1 links. They can be changed as soon as more precise details about an outage are known.
  • For internal's T1 links, responsibilities is of course on hosting T1s.
