IP Transit
IP transit is a terminology used to describe the interaction of two network providers. As we all know, the networks all over the globe are connected with each other through the internet. The internet services are provided by companies called the Internet Service Providers (ISPs). The ISPs are classified into three tiers (Tier-1, the aTier-2and Tier-3). Tier-1 ISPs are called the transit providers as they are responsible for internet connectivity around the globe and provide internet access to lower level ISPs. The Tier-2 ISPs sign a Service Level Agreement (SLA) with the transit providers under which they are provided a part of the internet for a pre defined price. The ISPs, in return, charge revenue form their respective customers. The transit providers can provide transit to the network providers of an entire country.
IP Transport
The term IP transport generally comes into light when we talk about the technical aspects of transporting data from one network to another. In the era of the internet, all the small networks are connected to each other. The interconnection of networks requires a considerable amount of equipment and technology. The data that you wish to transport has to travel through multiplle networks which contain various network devices. The interaction of all these networks is achieved through a well structured framework of protocols functioning at different levels of the network. These protocols helps to create a secure passage for data to reach its destination. Also, the data that is send cannot be sent as a whole through the transmission medium. The data have to be broken down into small fragments and transmitted.
Another aspect to IP transport is the transmission medium. The data has to be carried out physically from one the source to the destination. Some of the most widely used transmission media are the co-axial cable, the twisted-pair cable and the fibre optics among others. Each of the transmission medium is limited to a fixed capacity called the bandwidth. Also, to transmit data at a certain rate you need a minimum of bandwidth. For example, to transmit data at 300 mbps you need 1 Gigabit ethernet transport.
Transit vs Transport
IP transit and transport are both cogs of the same wheel. If you want the transmission of data over long distances you want both these to work efficiently.
While the IP transit provides you with access to networks much beyond the reach of your ISPs, IP transport is imperative to transmit the data physically over the network.
