Introducing Zenlayer Cloud Router – Layer 3 Networking Made Easy

We recently added Zenlayer Cloud Router – a layer 3 full mesh networking product – to zenConsole as part of our suite of cloud networking services to help you streamline your business operations.


What is a layer 3 network and why do I need one?

While layer 2 networks (point-to-point networks) have their use and are generally fine for data transfers between a few nodes, they’re not built to scale and can become a nightmare for IT teams to manage as your business operation grows. Layer 3 networking enables an easily scalable, full mesh network that reduces operating costs while simplifying IT infrastructure and improving resource management. Plus, layer 3 networks are inherently more efficient at data transmission due to automatic routing.

Reduce operating costs

If your business operates multiple nodes (data centers, clouds, offices, retail stores, or other locations with internet connectivity) that are spaced out geographically, trying to connect them using layer 2 networks can get very costly, very quickly.

For instance, say your business is headquartered in California and you have four offices located in four other states (see Layer 2 network above). Connecting the four out-of-state offices to your headquarters in California requires four point-to-point connections at a minimum. Even then, transferring data from one out-of-state office to another requires routing traffic from the origin office to your headquarters, then from the headquarters to the destination office. Not efficient.

In contrast, a single layer 3 network can cover all five nodes (see Layer 3 network above) and provides the best paths for traffic between your connected nodes, reducing your operating costs and improving data transmission efficiency.

Simplify IT infrastructure

The full mesh structure provided by a layer 3 network also makes fixes, updates, and general maintenance to your infrastructure easier to perform. Rather than updating each of your nodes separately like you would on layer 2 networks, you can roll out updates to all your connected layer 3 nodes at once.

Improve resource management

Similarly, because a single layer 3 network connects all your available resources together, you’ll be able to instantly access them anywhere within your network, from any one of your connected nodes.
