![]() ![]() ![]() We can examine the differences with a network flow diagram demonstrating patterns in a small virtual private network.Īll VPNs work in part by exploiting the bi-directional nature of network tunnels. If node A is right next to node Z, the mesh won't arbitrarily route all of its traffic through node M in the middle-it'll just send them from A to Z directly, without middlemen or unnecessary overhead. In sharp contrast, a mesh network understands the layout of all its member nodes and routes packets between them intelligently. All VPN traffic has to flow through that central server, whether it makes sense in the grander scheme of things or not. A conventional VPN is much simpler than a mesh and uses a simple star topology: all clients connect to a server, and any additional routing is done manually on top of that. ![]() The biggest selling point of Nebula is that it's not "just" a VPN, it's a distributed VPN mesh. Today, we're going to dive a little deeper into how you can set up your own Nebula private mesh network-along with a little more detail about why you might (or might not) want to. ![]() Further Reading Nebula VPN routes between hosts privately, flexibly, and efficientlyLast week, we covered the launch of Slack Engineering's open source mesh VPN system, Nebula. ![]()
