9a3c652a51 Get rid of expiration in Capability and Tag and move this to NetworkConfig so it can be set network-wide and reset if needed. Also add NetworkConfig field for this and centralize checking of credential time validity. 2016-08-22 18:06:46 -07:00

38dfebad8c IPv6 NDP emulation flag in NetworkConfig, and implement Docker-friendly
(and other host friendly) IPv6 /80 magic subnetting to allow massive
multicast-free NDP emulated IPv6 networks where each host can have a
/48 worth of IPv6 IPs for internal containers, VMs, etc.

Alan Kay, thou art avenged.

f69454ec98 (1) Make ZT_ naming convention consistent (get rid of ZT1_), (2) Make local interface a full sockaddr_storage instead of an int identifier, which turns out to be better for multi-homing and other uses. 2015-09-24 16:21:36 -07:00

3ba54c7e35 Eliminate some poorly thought out optimizations from the netconf/controller interaction,
and go ahead and bump version to 1.0.4.

For a while in 1.0.3 -dev I was trying to optimize out repeated network controller
requests by using a ratcheting mechanism. If the client received a network config
that was indeed different from the one it had, it would respond by instantlly
requesting it again.

Not sure what I was thinking. It's fundamentally unsafe to respond to a message
with another message of the same type -- it risks a race condition. In this case
that's exactly what could happen.

It just isn't worth the added complexity to avoid a tiny, tiny amount of network
overhead, so I've taken this whole path out.

A few extra bytes every two minutes isn't worth fretting about, but as I recall
the reason for this optimization was to save CPU on the controller. This can be
achieved by just caching responses in memory *there* and serving those same
responses back out if they haven't changed.

I think I developed that 'ratcheting' stuff before I went full time on this. It's
hard to develop stuff like this without hours of sustained focus.

57c7992c78 GitHub issue #191 - kill intra-network multicast rate limits (which were not well supported or easily configurable anyway) -- this is really left over from the old collaborative multicast propagation algorithm. New algorithm (in for a while) has been sender-side replication in which sender "pays" all bandwidth, which intrinsically limits multicast. 2015-06-26 12:36:45 -07:00

03dc823ad7 (1) Back off a little on default max multicast limit since 128 is pretty bandwidth heavy, (2) add a little to default multicast rate limit since new MC algo is fairerererer, (3) decided not to involve netconf masters in multicast so take that out of list of who gets LIKEs. 2014-10-10 12:55:06 -07:00
