What are Tier 1 and Tier 2 Providers? < back to blog

23 Sep 2016

The Internet is a powerful tool that has accelerated the modern age and expanded significant global communication. From computers and televisions, to tablets and mobile phones, accessing the Internet has become a daily activity whether we are in our homes or in our workplace. Internet Service Providers (ISPs) are at the centre of that access. These providers evaluate the most efficient ways to achieve quality service with the best budget for their users. It’s important to understand the difference between Tier 1 and Tier 2 providers to find the best fit for your needs.

The technical meaning of a Tier 1 provider is being a supplier whose network is transit-free. This tier level can reach every network on the Internet without purchasing IP transit, and they are typically made of large national or international ISP, such as Sprint or Verizon. Directly connected to the backbone of the Internet, they offer the highest speed connections and most reliable networks. Another advantage of having service from a larger Tier 1 ISP is that solving any difficulties can be much simpler with only one company to deal with.

Tier 2 providers purchase their Internet service from a Tier 1 ISP, and they usually cover a specific region. Typically, these providers will pair with businesses to provide personal attention, though they may have lower quality networks and slower speeds than Tier 1 ISPs. Tier 2 peers with some networks, but also requires IP transit to reach some portions of the Internet. Tier 2 providers are most common, due to the simplicity of purchasing transit from a Tier 1 network than it is to peer with them. When you are searching for an ISP in Ireland, it’s best to understand their differences before deciding on the type of provider that will suit your needs.
