IP transit is a service in which an Internet Service Provider (ISP) enables traffic to travel through its network in order to reach a destination. To access all internet routes, you’d require directly connecting to all autonomous systems.
However, doing this isn’t possible all by yourself. You’d require connecting to an ISP who can reach out to any network across the internet in Canada.
An internet service provider offering IP transit services in Canada to users is usually called “going upstream.” The traffic traveling from the internet and destined towards the customer is called “going downstream.”
Tiers Of IP Transit Providers in Canada
There are three tiers of IP transit providers in Canada. Let’s take a look at all of them in detail:
1. Tier 1:
The internet service providers (ISPs) belonging to Tier 1 have an international reach. They form a global network and peer with one another, on which tier 2 and tier 3 ISPs connect. Tier 1 ISPs don’t charge each other for traffic transfer while peering, but they charge the ISPs belonging to lower tiers for transiting traffic to their networks in Canada.
2. Tier 2:
The ISPs of Tier 2 have their reach in about one or two continents along with large networks. They are required to purchase IP transit from Tier 1 ISPs. For avoiding the cost Tier 1 charge for transiting, Tier 2 ISPs peer with one another, usually at no cost, to expand their reach in Canada.
3. Tier 3:
Internet service providers of Tier 3 are local providers having a national reach. They purchase transit from both higher tiers for minimizing the expenses associated with the IP transit prices of Tier 1.
IP Transit and DIA in Canada: What’s the Difference?
DIA is primarily used for general objectives and is the most widely used internet service across the globe. However, IP transit is a better option for organizations with intensive bandwidth functions.
IP transit in Canada is essential for firms dependent on reliable and persistent internet access. For example, IP transit is suitable for manufacturing, eCommerce, healthcare, financial trading, and the banking industry. As such, inadequate events of latency and periodic outages might cost a lot of money.
IP transit in Canada is also ideal for organizations with huge transfers of data. Also, think of eCommerce operations, video files, backup servers, 4K streaming, editing audio, cloud computing storage, and more.
As for DIA, the connection between a customer’s website and the internet is known as Dedicated Internet Access (DIA). It means that a specified amount of bandwidth has been dedicated and sold to a customer for its use.
Even if there’s congestion on the network, a private and dedicated lane will allow you to perform your internet activities with ease.
IP Transit vs. Transport in Canada
While IP transit in Canada refers to connecting internet service providers to broader networks, IP transport directs towards the physical transmission of data among networks. It’s concerned with the protocols’ frameworks required to pass through these multiple networks while prioritizing security.
However, you require IP transit and transport to work efficiently for transmitting data over long distances in Canada.
There’s another consideration that the data cannot be completely received and sent through a single parcel, and has to be fragmented into pieces with bandwidth limits determining the amount of data that can be sent over time.
The physical transmission medium, fiber-optics or co-axial cables, dictates the speed and bandwidth of IP transport.
IP Transit vs. Peering in Canada
Peering is when two or more independent networks directly interconnect to exchange traffic. This is done without charging for the traffic or the interconnection in Canada.
Whereas transit is when an autonomous network conforms to carry the traffic streams between another autonomous network and all the other networks. As no traffic can directly connect to all networks, the network offering transit services delivers some of the IP traffic indirectly using multiple transit networks in Canada.
What is a BGP Community?
A Border Gateway Protocol (BGP) community is a transitive and optional feature identified and passed to other BGP peers. You might see this community as a marker attached to the BGP routes traded among two peers.
Every IP transit internet service provider supplies a set of communities that would be accepted and allow manipulation of traffic in an ISP or in the peers’ relation of the ISP. If not previously agreed upon, other communities will get deprived of the BGP updates.
BGP communities allow users to set local route choices or perform AS-PATH pretending. A customer route can seem less preferred to the peers of ISPs or ISPs themselves.
Here is an example of the BGP community:

You can see that the customer doesn’t want ISP1 to send traffic using the direct connection. However, the customer wants to keep ISP1 as a backup if the ISP2 link goes down.
FAQs – IP Transit in Canada
Is IP Transit Internet in Canada?
IP transit is also known as internet transit or the internet. For adding complexity to the usage of this jargon, IP transit providers are often known as upstream providers in Canada.
What is the difference between IP Transit and peering?
There are multiple differences between IP transit and peering. A key distinction is that networks consenting to peer do not exchange any money. An operator can easily lessen being dependent on upstream transit providers through peering. But, not all operators seek a high number of peers.
What is BGP IP transit?
Various autonomous systems drive traffic and convey route information through a protocol called the Border Gateway Protocol (BGP). IP transit is a service using which networks have access to the complete internet through BGP in Canada.
Is IP Transit layer 2?
A tier 2 network is an ISP engaging in peering practices with other networks and buying IP transit to acquire a part of the internet.
The vast online world, known as the Internet, is a Global Wide Area Network (GWAN) that enables networks to communicate. This is what’s known as IP transit. It occurs only if IP traffic can reach its destination by utilizing a TCP/IP stack.
Comprehending the concept of IP transit in Canada allows users to make smarter decisions about how their customers reach their apps and sites and how their firm accesses the internet.
So, to provide you with a better understanding, we jotted this guide down to learn about the purpose and effectiveness of IP transit.
