Coding Join the Alliance Upcoming Events SVA Streaming 2.0 Open Caching Can Improve Streaming Video Delivery for Everyone OTT operators, CDNs, ISPs, and everyone involved in streaming can benefit by embracing Open Caching. Featured Presentation Watch or reach about the latest presentation given on Open Caching. In this presentation, Jeff Budney of Verizon talks about delivering content through Open Caching at the edge. Most notable are the performance numbers measured by Verizon on real-world traffic. Jeff Budney, Manager Core Network Planning Streaming with Open Caching on the ISP Edge The delivery of high quality streaming video via the Internet presents serious challenges for Content Providers, Content Delivery Networks and Internet Service Providers. This presentation will cover industry trends in streaming media, how Verizon has traditionally received streaming traffic, the efforts within industry organizations to improve the streaming video experience through Open Caching and the results seen at Verizon from deploying Open Caching at a nationwide scale. Measurements will be presented for buffering, video start failures and other key metrics from a production streaming video service.

Open Caching Logging Requirements Specification Specifies requirements for Open Caching System (OCS) for Logging data to help track data acquisition and delivery of it to the end user Open Caching Logging Requirements Specification Specifies requirements for Open Caching System (OCS) for Logging data to help track data acquisition and delivery of it to the end user Open Caching Performance Measurement Specification This document specifies measuring Key Performance Indicators (KPI) of the Open Caching Nodes (OCN), specifically, both at the ingress and egress points of OCN within an ISP environment Open Caching Performance Measurement Specification This document specifies measuring Key Performance Indicators (KPI) of the Open Caching Nodes (OCN), specifically, both at the ingress and egress points of OCN within an ISP environment Open Caching Relayed Token Authentication This document specifies relayed token authentication for open caching to support generic workflow for CDN Uniform Resource Identifier (URI) signing use the relayed tokenization mechanism Open Caching Relayed Token Authentication This document specifies relayed token authentication for open caching to support generic workflow for CDN Uniform Resource Identifier (URI) signing use the relayed tokenization mechanism Open Caching Content Management Operations Specification This document specifies Open Caching Content Management interface and the functionality requirements from the ISP Open Caching system and interface between the SP Open Caching Controller and the CDN Open Caching Content Management Operations Specification This document specifies Open Caching Content Management interface and the functionality requirements from the ISP Open Caching system and interface between the SP Open Caching Controller and the CDN Open Caching Content Management Operations Specification This document specifies Open Caching Content Management interface and the functionality requirements from the ISP Open Caching system and interface between the SP Open Caching Controller and the CDN Open Caching Content Management Operations Specification This document specifies Open Caching Content Management interface and the functionality requirements from the ISP Open Caching system and interface between the SP Open Caching Controller and the CDN The Components Of An Open Caching Network The architectural diagram above describes the flow of traffic through Open Caches in an Open Caching Network, illustrating the interoperability between Content Owner, ISP, and CDN. Driving that interoperability are the core components, connected through APIs, which enable the fundamental capabilities to mange delivery, caching, logging, and more. Provisioning Configuration Interface Content Management Logging Request Routing Control Plane Open Caching Technical Specifications The SVTA’s Open Caching is a series of functional requirements and specifications. The functional requirements define the network architecture and functionality, while the specifications define the functionality through API operation. The SVTA LABS initiative then codifies the specifications into working reference code. All of the functional requirements and specifications can be found below. They are available free to the public.
