Hi folks,
Writing up an article which is near ready to publish and I want to make sure
the terms I seek to elaborate upon are as accurately conveyed as possible.
To that end, my current task is to understand "totem" vs "token" and how this relates to
Quite user friendly description of Totem and Token is
https://discourse.ubuntu.com/t/corosync-and-redundant-rings/11627
the protocol for consensus in modern Corosync (Post-RHEL 6), as distinct
(if I grok) from the transport protocol "kronosnet".
kronosnet from corosync pov is "just" another transport protocol.
Corosync (historically) supported udp multicast, udp unicast and
infiniband for sending/receiving packet to/from wire. Kronosnet is used
same way - for sending/receiving packets.
Could someone help me out by shedding light on the difference between the "token" in
circulation, whether a "totem" concept of some sort is still valid, and how this all
relates to modern Pacemaker-Corosync HA clusters?
There is really no difference from very high level of view.
Honza
Thanks,
Mik
