Can we connect to Tier 1 ISP directly?

Customers can connect to any ISP. Peering is done between equivalent- sized partners (tier 3 to tier 3). Transit or fee-based peering is done where there are unequal traffic flows (tier 2 to tier 1). Peering and transit arrangements may be established directly or at third-party exchange points.

What is the difference between a Tier 1 and Tier 2 ISP?

As alluded to above, the first major difference between Tier 1 and Tier 2 networks (and their respective providers) is scale. Tier 2 providers are thus the primary downstream IP clients for Tier 1s – and in turn, they typically serve as the main source of IP transit for Tier 3 ISPs.

What is Tier 2 and tier 3 support?

Tier 2 staff have the knowledge base and skills to handle more complex customer issues and will often use remote control tools. Tier 3 personnel are involved when the only way to resolve a customer issue is a design change, enhancement, or bug fix that requires a software or hardware update to the product.

What do Tier 1 Internet service providers do?

Traditionally, Wholesale Tier 1 Internet Service Providers have focused on Distributed Denial-of-Service (DDoS) protection in terms of protecting against volumetric attacks. That is, attacks that send large volumes of traffic towards target IP addresses, often from distributed sources.

Why do you need Tier 1 IP transit fabric?

Operating your own Tier 1 IP Transit fabric lends itself to offering Wholesale IP Transit to lower -tier consumers of transit, and in so doing to aggregate demand and drive buying volume up – therefore your own price point down – for the elements involved. The aging of contracts helps in building margin.

What’s the total capacity of IP transit and peering?

In addition to IP Transit we connect services to a number of peers, such as Mega-IX and Any2-IX. The total of upstream IP Transit and peering connectivity is approximately Nx2, where N is the contracted capacity of transit potentially consumable by customers.
