Kronosnet, often referred to as knet, is a network abstraction layer designed for High Availability use cases, where redundancy, security, fault tolerance and fast fail-over are the core requirements of your application.

Kronosnet is the new underlying network protocol for Linux HA components (Corosync), that features ability to use multiple links between nodes, active/active and active/passive link failover policies, automatic link recovery, FIPS compliant encryption (nss and/or openssl), automatic PMTUd and in general better performances compared to the old network protocol.
