To make it work, communication had to be open
between all the different networks. This lead to
some of the first Tier 1 networks.

What is a Tier 1 network?
Why do we still think of this as the backbone
of the Internet?
12
Each network on the Internet is represented by a
unique number. The quantity of networks connected
to the Internet has exploded in recent years

This is primarily due to the desire to improve
performance by connecting to multiple providers.

Even when connecting to multiple providers,
getting data from one network to another still
relies on transiting multiple Tier 1 networks.

Smart networks have discovered that bypassing the
Tier 1 networks by peering directly with other
networks you can save money or improve
performance.

Peering refers to the free exchange of traffic
between two different networks. Peering can be an
effective strategy for reducing IP transit costs,
as well as a way to improve performancebut
generally not both.

Mzima has taken the performance-based approach to
broadband peering to the next level.

This gives Mzima an unequaled number of options
to route performance-sensitive traffic.
22
Mzima peers directly with over 500 networks
around the world.

Mzima peers directly with over 500 broadband ISPs
and regional network providers around the world
in most cases at multiple locations a very
large donut indeed! Connectivity to multiple
Tier 1s is important this gives us
options Bypassing them wherever possible is
even more important skip the old, poorly-suited
backbone and take the content straight to the
users! Mzima is the first and only network that
since its very founding has used donut peering
to improve performance, not save money.
