Regardless if cloud connectivity is accomplished over the internet or through leased lines, there is bound to be some level of impairments due to continuous loss and occasional link failures. To mitigate continuous loss, reactive and repairing technology such as retransmission (commonly known as ARQ) is typically applied. With more reliable connections available, forward-error correction (FEC) can be used instead. To handle link failures, technologies like hitless protection and bonding of multiple connections can also be applied. Both of which can be paired with FEC or retransmission for utmost reliability.
Therefore, ingesting content into public cloud environments requires a toolbox that consists of retransmission, FEC and link bonding. This toolbox makes up the foundation of Net Insights Emmy Award-winning Nimbra-based cloud ingest solution.
But to complicate matters further, there is not one single retransmission technology that everyone uses. There is a multitude of different options available, with the top three being the standards-based Reliable Internet Stream Transport (RIST), the open source Secure Reliable Transport (SRT) and the widely industry adapted Zixi protocol. The reality today is that different cloud environments and different cloud-based applications support different retransmission technologies. That’s why the Nimbra cloud ingest solution has taken an open approach and supports all three retransmission solutions, letting you to pick the technology that is compatible with your cloud environment and cloud applications.
