Network of Nodes

The Waku Network

Typical Network Topology

Note:
Let’s take a look at what a network of Waku nodes might look like.  
It may be too intricate for a clear understanding on first glance, but we’ll look into each feature in detail next.  
For now it’s important to have a high-level understanding of what each element represents:

• the shaded circles represent Waku Nodes contributing at different levels to the network

• the shading itself represents that node’s capabilities/resource availability (we’ll look at this concept next)

• the colored, dotted lines represent different pubsub topics. Remember that a specific contribution always belongs to a specific pubsub topic, hence the separate pubsub topics represent separate sub-networks.

• the solid arrows represent some request/response protocols, such as store, filter, or lightpush

• the dotted boxes show what content topics (i.e. applications) a node is interested in. A node that is purely providing a service to the network might not care.

• there are also dashed lines to “auxiliary networks”. These represents breakouts from the Waku network to auxiliary protocols, such as bridging to Waku v1, DNS used for discovery, etc.
