[kamailio/kamailio] async sleep with millisecond precision (#2006)

by Paweł Pierścionek

Hi, I've implemented a ringless millisecond async sleep using sorted linked list and 1 millisecond timer. Timer queues tasks that are due for execution with async_task_push. https://github.com/urtho/kamailio/tree/microsleep If this is worth including in the master then I can do comments, docs, better naming and millisecond async_route version. Coupled with a leaky bucket algorithm (eg via HTTP microservice in GO) this gives me a nice SIP INVITE shaping functionality where I can evenly space request bursts per customer without any dropped calls. No more per customer or per group spikes or rate limit drops. SIPP load testing shows now memory leaks nor other unexpected behaviour for multiple 250 req/s parallel streams. -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] rtpengine: hashing algorithm not offering a good enough distribution (#1911)

by Ionut Ionita

We are having problems in our environment with the way rtpengine distributes RTP sessions. It doesn't provide a good enough distribution among RTP nodes and this is mostly because the current algorithm is quite simple, doing the sum of the characters in the callid and after that applying a 0xFF mask over this(which contributes even more to the distribution of this algorithm). This may affect our systems under heavy load and we've been looking for an alternative. To have something to compare I have designed a tesing application in which I generate CallIds, apply a hashing algorithm and assign the result to a set/node. For example I have 10 nodes each of weight 10. Let's say hash value is 125 I do 125 mod (10 * 10) = 25 therefore the hash will go to node 3. I've been running some tests over various hashing algorithms such as: SHA 256, jenkins(simple hashing algorithm found on wikipedia), md5, sha1, ripemd, crc32 and the one used in the rtpengine. For each algorithm I test from 1000 randomly generated callids to 10 million with a multiplyer of 10(5 tests for each algorithm). The callIds have 16 randomly generated bytes and 16 fixed bytes which are always the same. This way I'm trying to reproduce the way callIds are generated most of them containing a randomly generated part and a fixed part. >From the results I can tell for sure that multiple rounded hashing algorithms from libssl(md5, sha1, ripemd, sha 2) offer a much better distribution than a trivial hashing function so we're looking to change the current algorithm with SHA 1 because SHA 2 takes more time without significant improvement. It would be nice to push this upstream, but there are some issues. First, using these functions, rtpengine module will depend on libssl. What is your opinion about this? I've looked if we can copy any of the algos from libssl into the code but this is not as easy as it seems. Secondly, if you agree to replacing the algorithm, how would you approach the issue: only replace the current one or add the posibility for the user to select between multiple algorithms? Any suggestion of testing scenarios or hashing algorithms that we've not considered is much welcome. The results of the tests are attached to his post.
