You need to scale the network to handle increasing traffic and ensure the required service quality.
There are two methods for balancing surging user traffic – GeoDNS and BGP Anycast (a brief description of these technologies).
We'll examine how large companies tackle this task.
Let's move on to how you can solve these problems yourself, using open utilities and route information data.
Following this, we'll discuss an approach for expanding the BGP Anycast network.
For a global network expansion, two key questions arise:
- Where (in which country) should a new node be installed?
- Which local provider should it connect to for optimal service quality?
To answer the first question, we'll utilize the RIPE Atlas public toolkit to create an RTT map, highlighting regions with maximum network delays. This reveals the weak points in our current network.
To answer the second question, we'll describe a method based on analysing route information, which can be used to select the best providers in the region.
Simplistically, the method can be described as follows:
1. We gather route information from some BGP collector (e.g., RIPE, Route Views, PCH)
2. Using this data, we identify major players in the market – regional leaders, employing various metrics (a brief overview of these metrics and the algorithms behind them is provided).
3. We create a rating of the most promising providers for connection and select candidates from this rating.
This systematic approach swiftly identifies optimal locations for new node installation, enabling effective network development.
