Reliable Low Latency Streaming With SRT: Now Available in Wowza Streaming EngineAugust 28, 2017
From user-generated content to online gaming; from financial trading to security platforms; today’s streaming apps and services are highly interactive experiences, facilitated by low-latency streaming delivery. But achieving low latency, with high reliability and security simultaneously can be a challenge, especially when delivering over the public internet.
With the latest update to our award-winning Wowza Streaming Engine™ software, you can deliver the experiences your audience demands. Version 4.7.2 offers the ability to ingest video over SRT (Secure Reliable Transport): an open-source video transport protocol that enables the low-latency delivery of high-quality, secure video across sub-optimal networks. SRT offers an open source alternative to expensive, and often proprietary, video transport technologies.
Recently, Wowza’s engineering teams performed benchmark tests of SRT, and the results showed greater reliability of throughput and packet loss, and improved bandwidth utilization when encountering network bandwidth fluctuations. During a number of long-haul tests, from Germany to Australia using a consumer DSL connection, the results showed a 7.5x increase of throughput with SRT, compared to RTMP connections over TCP.
SRT offers seamless delivery across the technology stack, even when conditions are less than ideal. It provides an alternative to TCP connections through a reliable UDP transport solution for low-latency video, along with:
- Packet loss recovery.
- End-to-end security with AES encryption.
- Network health monitoring between endpoints.
- Simplified firewall traversal.

At Wowza, we are committed to incorporating SRT throughout our technology offerings; its inclusion in Wowza Streaming Engine is just the beginning. We’re a founding member of the SRT Alliance, announced at the 2017 NAB Show, and have teamed up with Haivision to bring this technology to content distributors.
