Here are Belshe's results curated into a nice graph: Load time/bandwidth vs. Load time/latency Load time/bandwidth vs. Load time/latency It should be clear that increasing site speed by increasing bandwidth is not the most effective way to achieve better performance. On the other hand, by reducing RTT (round-trip-time) or latency, we can see consistent improvements in page load time . Networks vs Internet Peering vs Transit To better understand our topic, we need to start with the basics of Internet topology. At its core, the global Internet is made up of multiple global, regional and local networks. As of 2018, there are over 60,000 ASs (Autonomous Systems). These networks belong to governments, universities, ISPs.
Among them, we distinguish Tier 1, Tier 2 and Tier 3 networks. These Buy Bulk SMS Service levels represent the independence of each network on the Internet as a whole. Tier 1 networks are independent, meaning they don't have to pay to connect to anywhere else on the Internet. Tier 2 networks have peering agreements with other ISPs, but they also pay for transit. Level 3 networks, the lowest level, connect to the rest of the Internet by purchasing transit from higher levels. They are basically like consumers who have to pay to access the Internet. Peering relationship means that two networks exchange traffic on an equal basis, so that neither pays the other for transit. The main benefit of peering is drastically lower latency.
How web requests traverse the hierarchical network of ISPs How web requests traverse the hierarchical network of ISPs In the image above, we see a classic scenario, where the request goes through the hierarchical network of Tier 1, Tier 2 and Tier 3 ISPs in order to retrieve a website hosted in a data center in a remote location. The arrows represent the path of the web request. The dotted arrows represent transit connections and the solid arrows represent peering connections. Once you reach the Tier 1 provider, your relationship with another provider on the same tier is an equal relationship. Tier 1 networks connect to others and route their requests exclusively through peer partners.
