Peering Policy
DSM (GB) (AS48070) operates an open policy and will generally welcome all requests for peering.
We do not require a signed agreement but are happy to do so where the agreement is reasonable.
Guidelines
- Hot-potato routing is implied. MEDs are not honoured.
- Settlement free peering.
- Neither party should ever establish a gateway of last resort configured towards the other party’s network.
- A minimum of 5 Mbit/s is generally recommended but not required.
- We reserve the right to refuse peering with any party.
