Customer Routers

The naming convention used for routers on customer's premises is as follows:

CUST-NAME.(upstream_router_type).(locode).twdx.net

CUST-NAME is capitalized string of the customer name. It is truncated at 11 characters.
upstream_router_type and locode signify the upstream TOWARDEX router providing connectivity to that customer.

Network Interface for Settlement-Free Interconnection (SFI)

The naming convention used for routers on the peer network's premises is as follows:

(network_name)-px.twdx.net

network_name: specifies name of the network that is interconnecting with TOWARDEX.
-px: stands for Private Exchange (PX) to signify a Private Network Interconnect (minimum speed 10GE).
