Striiming

Striiming is a data streaming technique intended to improve delivery over variable networks by interleaving data into stripes and reassembling it at the receiver. The term blends streaming with striation, reflecting the data layout that allows parallel transmission and selective recovery. It is discussed mainly in media delivery and real-time data contexts.

Etymology and concept: The word is a portmanteau of stream and striation. The approach arose from attempts to mitigate jitter and burst losses by spreading data units across multiple transmission opportunities rather than sending large chunks consecutively. Striiming can be viewed as a stripe-based variant of chunked streaming with explicit stripe indices.

Mechanics: The sender partitions the stream into stripes, each containing a small, coherent unit such as a video slice or a set of updates. Stripes receive sequence numbers and stripe indices. A scheduler orders stripes based on network estimates, and the receiver buffers and reorders them to reconstruct the original sequence. Optional parity data can improve resilience.

Benefits: Striiming can reduce tail latency and improve resilience to burst losses by decoupling delivery from individual chunks. It enables partial recovery, allowing unaffected stripes to contribute when others are delayed or lost.

Limitations and adoption: The technique adds encoding and decoding complexity and requires synchronized timing and metadata. It is not widely standardized, which can hamper interoperability and tooling. Adoption tends to be domain-specific, appearing in research prototypes and some proprietary systems.
