OctoCAST is a reverse HTTP proxy, sometimes referred to as an HTTP accelerator or a caching server. It stores files or fragments of data in memory, allowing them to be served quickly. It is designed for modern hardware, modern operating systems, and heavy workloads.

OctoCAST is also a flexible tool. The OctoCAST configuration language is powering up fast and allows the administrators to express their wanted policy. OctoCAST has proven its effectiveness on both large and expensive servers as well as small infrastructures.

Its focus is performance and flexibility and it is designed to run on 64-bit architectures.

OctoCAST bridges local area networks by repackaging selected multicast traffic on an enterprise network as unicast and sending across WAN connections to one or more destinations. It can also be used to duplicate a single video stream to multiple unicast destinations, to enable private sessions or secure content to be shared with entities around the world. An advanced traffic shaping algorithm ensures the quality of service (QoS) reflecting video payload on any network while maintaining consistent bandwidth utilization.
