Attention is currently required from: osmith, neels, dexter. Hello osmith, Jenkins Builder, neels, laforge, fixeria, dexter, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-bsc/+/29751 to look at the new patch set (#5). Change subject: Introduce support for MGW-pinning per BTS ...................................................................... Introduce support for MGW-pinning per BTS This feature allows pinning each BTS to a specific MGW from the configured pool. The pinning can be soft or hard (strict). If strict pinning is not set, the configured MGW is selected with priority, but other MGWs can still be selected during each call setup if the preferred MGW is found not available at that time, hence avoiding denial of service for the entire BTS if that MGW goes down. If strict mode is selected, the call will be refused if the configured preferred MGW is not available at the time the call is set up. It is useful to use this feature when Osmux is configured between the BTS and the BSC and an MGW pool is in use. This way the BSC is capable of grouping all the calls of a BTS towards one MGW, hence taking advantage of the Osmux trunking optimizations to reduce link data usage (AMR payload of several concurrent calls ending up sharing the same underlaying UPD packet). Furthermore, this allows the operator to intelligently spread load over the MGW pool in order to avoid ending up with more than 256 concurrent Osmux circuits on any of the co-located MGWs in the pool (maximum supported at the moment).
