Overview

Inter.link offers a Pan-European 100G/400G network with high-quality connectivity to carriers, content providers, and internet exchanges. A three-digit number of peerings enables Inter.link to provide outstanding reach and low latency.

If you want to experience that low latency for 30 days, reach out for our free IP Transit trial.

In addition, BGP communities for traffic engineering, support for BGP FlowSpec, and fast service delivery (under 48 hours on average) add compelling value to Inter.link’s service.

Inter.link IP Transit service delivers best-in-class performance due to the breadth and depth of the Inter.link backbone network’s connectivity to a variety of networks, including smaller regional networks. By contrast, many Tier 1 and Tier 2 ISPs don’t peer with smaller and regional networks. Inter.link’s commitment to in-depth peering relationships means that customers can gain the best performance to the widest set of networks and users.

  • Larger networks available on request
  • Internet Access with BGP Session(s)

Components

VLAN
Requires a port
IP Transit can be handed over on a tagged VLAN, which can be defined by the customer, or VLAN untagged.

Specifying a VLAN ID is optional when ordering services on Inter.link ports, but there can only be a maximum of 1 service per port without a VLAN (there can be up to 4094 services with a VLAN ID).

Prefix(es)
Requires Port+VLAN(s); can be configured at the VLAN level only, this includes the untagged VLAN.
Prefix can be IPv4 or IPv6, ranging up to /32 and /128.

BGP Session(s)
Requires IPv4 Prefix for IPv4 BGP Session & IPv6 Prefix for IPv6 BGP Session
BGP Sessions, IPv4 and/or IPv6.

    Billing for IP Transit

    • The Committed Data Rate (CDR) must be at least 10% of the port line rate
    • Billing is on a 95/5 percentile basis with burst billed at the same CDR price per Mbps
    • Aggregated billing over multiple ports is now enabled on our portal but please speak to your sales rep if you need more detail

    Complete information on Inter.link pricing can be found in the Pricing section of the knowledgebase.

    Generalized TTL Security Mechanism (GTSM)

      The Generalized TTL Security Mechanism (GTSM) is a solution to mitigate BGP spoofing. It protects a BGP session by comparing the TTL value in the IP header of incoming BGP packets against a valid value. If the TTL value equals 255 it’s considered valid and the packet is accepted. If not, the packet is discarded.

      If you want to enable GTSM on your BGP session with Inter.link, please contact support@inter.link.

      Flowspec rules

      With FlowSpec, on a separate BGP session, customers can announce FlowSpec filter rules which will be installed in our network. This way, easy and customer-controlled filtering can help to mitigate DDoS attack before they reach the customer network.

      We are planning on adding additional filtering capabilities into the Inter.link Portal for customer’s whose equipment doesn’t support BGP FlowSpec.
