Frederic-Philippe Metz	fd3e2342c1	Implemented redis notification according to RTPENGINE-64 Thoughts on that topic so far: There's one thing to keep also in mind. What do we do if the call changes (streams) and the backup node is notified ? Currently we only know (by subscribing to the 'notifier-' prefix that in fact it has changed, but we don't know what has changed in detail. Subscribing to everything would lead to the problem that we have to take care about synchronising the the new streams with the old ones. Without having a look at the code that might be a lot of effort and ... I guess that's why richard likes to ... have clean states of the calls. Synchronizing is always a mess. Easier to delete and setup new. I thought about the following solution for makes things more abstract and easier to understand: 1. Whenever that call on a backup node (foreign call) has seen a packet (also timers are started then), we do not process any notification by a redis notification for this call (caus' the RTP-IP has already been switched). More precise and abstract that means: If a node has taken over the responsibility for that call (by having seen a packet), it assumes that notifications from the former node to be dropped. The call will be deleted when either the timer fires or (for other companies) the control channel address has also been switched and via that channel the call is deleted. 2. If a call has not seen a packet (inactive call on the backup node, seen as not responsible for that call but could become so), we accept all commands for that call on the backup node in the same way as on the original node. That means also deletions in-between and so on. I mean if the original node does it, why not accepting to do the same way on the backup node ?	10 years ago

Frederic-Philippe Metz	541e2999a9	Implemented redis-notification base feature. Currently, every rtpengine will subscribe to redis-keyspace notification so it will receive a notification when an call is inserted. If the call is not already handeled by the rtpengine, the call will be restored. The reason for this is to have in-place redundancy. Imagine you have multiple rtpengines running, eachone will have all calls of the others. When one rtpengine fails somehow, infrastructure guys use BGP in order to 'move' the IP address from one rtpengine to another. Thisone can handle the new calls instantly since they're already recovered by redis-notification feature. Next step is internally identify those calls in order to prevent some timers to delete the calls where no RTP flows. Second will be something we call 'partitioning'. It means that the subscription to a redis notify will only be for the keyspace a dedicated rtpengine writes to. This leads to the point that you can make redundancy groups (partitions) of the rtpengines.	10 years ago

Richard Fuchs	6d3865b971	Mass update - manual merge of rfuchs/socket-rework branch This brings master up to date with branch `rfuchs/socket-rework` at commit `b1bcc096b7`. The branches have diverged too much for a proper merge, so this is a manual (squashed) merge. The old master before this merge can be found in branch `old-master-before-socket-rework` (commit `82199216b2`). This is a complete rewrite of all socket handling routines. The most important functional change is that sockets aren't indiscriminately bound to INADDR_ANY (or rather in6addr_any), but instead are always bound to their respective local interface address and with the correct address family. Side effects of this are that in multi-homed environments, multiple sockets must be opened (one per interface address and family) which must be taken into account when considering RLIMIT_NOFILE values. As a benefit, this change allows rtpengine to utilize the full UDP port space per interface address, instead of just one port space per machine. The socket abstraction also makes it possible to support RTP over TCP in the future. Change-Id: If6cf4f42136229490186d2d2482fb4fc140c2b53	10 years ago
