9490b1f136 Try prioritizing cluster-send over direct send in cluster mode -- may improve cluster relaying reliability. 2015-11-06 13:38:56 -08:00

c9e6e60c09 Handle ZeroTier-RFC4193 IPv6 address NDP queries inline by spoofing responses if the addressing scheme matches -- this allows multicast-free instant lookup of local IPv6 for better performance and reliability. 2015-11-03 10:46:41 -08:00

f692cec763 Change how cluster relays packets -- just PROXY_UNITE and then send packet via normal ZeroTier front plane -- more efficient and eliminates fragmentation issues. 2015-10-27 14:04:12 -07:00

Adam Ierymenko
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

85b90f122a Final std::map<> from Switch, and add some smallish default values for hash size. 2015-09-04 15:35:43 -07:00

3f567a07ca Save a little bit of RAM by getting rid of overkill CMWC4096 non-crypto PRNG and replacing it with a simple non-crypto PRNG that just uses Salsa20. 2015-07-07 10:49:50 -07:00

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

Adam Ierymenko
d9006712f6 Completely factor out "desperation" from the core. I thought of a significantly simpler way to move all of this logic entirely into the containing service, liberating the core from any concern over the nature of its pipe to the outside world. 2015-05-21 15:58:26 -07:00
Adam Ierymenko
a1005ca858 Do not unite() peers across different IP scopes as this would pretty much never work. 2015-04-26 16:03:16 -07:00

5e331d6733 Restrict unite() to desperation==0 since NAT-t only works right now with direct links. 2015-04-10 10:13:50 -07:00

Adam Ierymenko
a69e1876f1 The concept of link desperation (escalating to less desirable transports) simplifies a ton of stuff. Loads of spaghetti logic can die since we no longer have to make these decisions down in the core. 2015-04-02 17:54:56 -07:00

2c8321be1f Pull logic to always send new multicasts to supernode since we need to do that differently, re-add support for active bridges, and remove some gratuitous use of std::set where not needed. 2014-10-04 13:15:02 -07:00
Adam Ierymenko
e7c81ef34e Turns out that needed to be a list after all. Also clean up Multicaster::gather(). 2014-10-03 22:03:19 -07:00

e1882b614b Some cleanup, Multicaster now sends multicasts as it gets additional members. 2014-10-01 14:05:25 -07:00
Adam Ierymenko
ae082c3cb8 Yay... now everything compiles! Getting close to testing on this. Still have not added backward compatibility support for relaying of multicasts to 0.9.X clients yet but that will be easy. Will test with heterogenous 1.0.0 clients only first. 2014-10-01 12:41:48 -07:00

282114e96c Makefile changes, and make Topology::getBestSupernode() return the "next" supernode if I am a supernode. Also some comment cleanup. 2014-08-19 10:09:21 -07:00
Adam Ierymenko
8a804b5257 (1) Disable firewall openers (its easy to re-enable), (2) Do some prep work for making supernode topology hot-updatable. 2014-08-05 14:05:50 -07:00
Adam Ierymenko
88bdb81791 Keep track of basic aliveness for peers regardless if direct or indirect connectivity and use this for multicast propagation. Also consolidate adding of active bridges via the same functor as regular multicast next hops. 2014-06-30 11:31:04 -07:00
Adam Ierymenko
458f6ae7c3 Only add active bridges to top of MC propagation list if they are alive. Otherwise a dead active bridge might kill multicast for us. 2014-06-26 18:13:48 -07:00

b117ff5435 Probable fix for GitHub issue #63 - do not unite() if either path is TCP, since doing so can result in asymmetric failed NAT-t over UDP if one side has a firewall that permits outgoing UDP but not incoming. 2014-04-10 11:17:54 -07:00
