	Kronosnet is a new network topology designed by ~~Red Hat~~ to provide highly adaptable, redundant and secure networking over both high and low-speed links.		Kronosnet is a new network topology designed by [[Fabio M. Di Nitto]] and [[Federico Simoncelli]] to provide highly adaptable, redundant and secure networking over both high and low-speed links.

	In a sense, kronosnet is similar to a VPN in that connections between nodes are on a common [[subnet]]. Unlike traditional VPNs though, kronosnet can ~~be configured to~~ use up to eight ~~physical~~ interfaces. While operating, the kronosnet daemon, <span class="code">kronosnetd</span>, will keep track of the latency between links. This allows for the fastest link to always be chosen. ~~This approach means that dead links need no special handling as they will have an infinite latency~~ and ~~thus never be used. When the link finally recovers, it will "just work", as it's latency will suddenly be reasonable again~~.		In a sense, kronosnet is similar to a VPN in that connections between nodes are on a common [[subnet]]. Unlike traditional VPNs though, that run on a point to point or point to multipoint setup, kronosnet is designed to run multipoint to multipoint, and can use up to eight links between each node. Multiple kronosnet interfaces can be configured on any given node. While operating, the kronosnet daemon, <span class="code">kronosnetd</span>, will keep track of the latency between links. This allows for the fastest link to always be chosen. Link failures are automatically accounted for and recovery is done automatically.

	This means that, so long as at least one link is up, communication to the host will work, regardless of what happens to the underlying network links!

All of this will the minimal of configurations. Once finished, kronosnet communication will be also encrypted.
