You need to procure the correct public Internet connection for your business. There are several options including broadband Internet, dedicated Internet access, IP Transit<\/a>, direct settlement-free or paid peering arrangements, and others. <\/p>\n\n\n\n

But, enterprises and mid-to-large-sized organizations usually weigh the differences between just two: Dedicated Internet Access (DIA) and IP Transit. This blog takes a closer look at which service might be right for you.<\/p>\n\n\n\n

Starting with the Bottom Line<\/h1>\n\n\n\n

Within Zayo, we often say that DIA is the right service if the Internet is FOR <\/strong>your business (it\u2019s an essential tool that allows your local or national business to run), and IP Transit is the right service if the Internet IS <\/strong>your business (it\u2019s what you sell, you use it to connect to other networks, or it\u2019s the primary gateway for global clients to access your applications and services).<\/p>\n\n\n\n

What is Dedicated Internet Access (DIA)<\/a>?<\/strong><\/h3>\n\n\n\n

DIA \u2013 sometimes also called Fiber Internet or Ethernet Dedicated Internet \u2013 is a premium service that offers a direct and exclusive connection to the Internet. Unlike traditional broadband that shares bandwidth among multiple users, DIA ensures your business gets a dedicated, consistent and reliable connection. Different companies provide DIA differently, so when shopping for a plan, make sure\u00a0you’re\u00a0getting the entire bandwidth you paid for.\u00a0<\/p>\n\n\n\n

Real-World Use Case:\u00a0<\/strong>Amanah Tech<\/a>, a Toronto-based colocation data center, partnered with Zayo to power\u00a0a recent data center expansion.\u00a0Zayo\u2019s underlying DIA network enables Amanah Tech to provide Internet access to its customers without\u00a0the\u00a0need\u00a0to develop complex\u00a0infrastructure\u00a0themselves.\u00a0With Zayo\u2019s high-bandwidth connectivity solutions, Amanah\u2019s clients now\u00a0enjoy\u00a0faster setup times, scalable services, and significant cost savings.<\/p>\n\n\n\n

What is IP Transit<\/a>?<\/strong><\/h3>\n\n\n\n

IP Transit also provides direct connections from a customer’s network to the global Internet. A fundamental element of IP Transit is that the Internet connection occurs in a data center rather than an office location, and is used to connect to specific networks, or autonomous system numbers (ASNs). Each IP Transit provider (like Zayo) establishes peering arrangements with other Transit providers, Tier 1 Internet providers, select Tier 2 providers, and hyperscalers. By connecting to a Tier 1 provider (like Zayo) with IP Transit, you gain access to their global peering exchange points and thereby access to the global Internet.\u00a0As a\u00a0Google Cloud Gold-tier Verified Peering Provider (VPP)<\/strong>, Zayo offers high-performance IP Transit with direct, low-latency access to Google services.<\/p>\n\n\n\n

Example<\/em>: A media provider needs IP Transit to make content easily and readily accessible by end-users. By connecting with a Tier 1 ISP over BGP, they obtain global access and ample capacity through the ISPs other connected networks (like CDNs) to help deliver streamed movies to their end-users. <\/p>\n\n\n\n

Both IP Transit and DIA are designed to provide robust Internet connectivity for businesses. Each offers high-speed, reliable Internet connections that can support a range of business applications. Fundamentally, the difference comes down to the composition of the service.<\/p>\n\n\n\n

Internet Service Providers (ISPs) that offer both differentiate between the services because they cater to different needs and operate in distinct ways. Understanding these differences can help you choose the right service based on your specific business requirements.<\/p>\n\n\n\n

Access Location<\/strong><\/h3>\n\n\n\n

Access location is code for how you use, buy, and consume Internet bandwidth. If you\u2019re a small-to-midsize enterprise whose core business relies on the Internet to reach your customers and applications, you\u2019ll need the reliability of a dedicated Internet connection (read: broadband alone may not be enough). For you, the main considerations of Internet access are:<\/p>\n\n\n\n
