NORDUnet Nordic infrastructure for Research & Education Global Video Alliance An overview of the GVA Service Model – a work in progress Presented to the Internet2 Spring Member meeting April 25, 2012 Washington, DC US Jerry Sobieski Director, International Research Initiatives NORDUnet
Nordic infrastructure for Research & Education What is GVA? “Global Video Alliance” Objective: A global, high-quality, video-conferencing service – High quality, multi-party, “tele-presence” (human interaction) capabilities – An intuitive user interaction with the service – Reliable, consistent, dependable, scalable, secure, manageable – Global reach – Global shared resources – Global interoperability – Open framework and standards based
NORDUnet Nordic infrastructure for Research & Education Why is this necessary? We need a common scalable Service Model. – Existing technical video standards do not address a shared global Service Model resource integration and federated authorization mechanisms, advanced scheduling, accounting, common user model, and other non-video but essential service issues. – Existing technical standards compete, overlap, conflict… We need a cannonical video service architecture The R&E community is key: – We have the global network and IT infrastructure – We have a culture of collaborating – finding common ground, essential to global adoption – We have substantial video assets and local, regional services already in operation. – We have an immediate and urgent requirement : Collaboration.
NORDUnet Nordic infrastructure for Research & Education The Global Video Alliance The Global Video Alliance mission is to develop that common global video services model. – An Open (but managed) process to define the service specification and underlying mechanisms to realize it… – Standards track – making the service model technology and vendor independent. And THE GVA will promote and coordinate the activities necessary to field and mature such a global service: – Develop a formal service architecture specification – Sharing developmental tasks – Fostering the common/federated policy that is required among participants – Identifying operational service processes: support, problem resolution, management, accounting, etc. – Engineering of the [global] video infrastructure to enable high quality ubiquitous video services – Feedback operational experience into standards

NORDUnet Nordic infrastructure for Research & Education Start with User Service Model The basic GVI User Service Model adopts a commonly understood “Meeting” paradigm The Meeting object includes attributes: – “attendees” (individual participants) – “venue(s)” conference rooms (group participants) – Scheduling parameters – date/time, duration,… – Features such as capture or streaming, privacy, etc. The user can easily manage the meeting: – Schedule the meeting, – Choose a meeting format (Interactive Class? Group meeting? Conf call? Concert?) – Notify/invite attendees; or otherwise announce the meeting… – Reserve appropriate meeting venue(s) – Record or stream/broadcast the meeting, – Live mgmt: Convene, recess/adjourn, and/or conclude the meeting…

NORDUnet Nordic infrastructure for Research & Education The Provider Service Interface The Provider service interface allows automated agents to locate and reserve the resources required for a meeting from a globally distributed resource pool. The User does not see or deal with the technical aspects of the global multi-party video provisioning. Operational agents and GUIs may be developed using the basic PSI that can allow service providers or other agents to interact with the service infrastructure, to monitor and manipulate the state of their resources.
NORDUnet Nordic infrastructure for Research & Education Resources As seen by the user: – Directory- sites and people – Schedule – Virtual Meetings Behind the scenes: – Universal dialing translation – MCUs, transcoders, etc – Capacity between sites – Resource brokers
NORDUnet Nordic infrastructure for Research & Education GVI Basic Service Processes User Interface (UI) – This is a basic component of the GVI framework, but it interacts with the GVI “service” via a set of standardized interface primitives and service concepts – Thus every local organization may have a unique User Interface, but all will support the GVA framework and Basic User Service Elements – This allows organizations to tailor the UI to their specific constituents’ needs, and software developers to implement innovative and differentiating value-added features … while maintaining compatibility with the global service model.
NORDUnet Nordic infrastructure for Research & Education Technical Issues TBD For a globally distributed system to interoperate, the “coin of the relm” is the Video Meeting Identifier. The VMID consists of two parts: – A globally unique “Video Service Provider” identifier that identifies the provider that is compiling the resources – And a local identifier that uniquely identifies the meeting within the Provider’s scheduling system/domain. Thus, by inspecting the VMID, a remote agent can determine which service provider is responsible for organizing the meeting. The primary Video Service Provider is responsible for acquiring/negotiating all the resources necessary to realize the video conference. The resources may be assembled from many service providers, and all such resources are linked to the VSP’s VMID.
NORDUnet Nordic infrastructure for Research & Education Other GVA Processes Resource Manager Responsible for allocating local video assets to meeting requests The resource manager is responsible for announcing local resources that are available to support multi- domain meeting provisioning. Resource Broker Responsible for locating and reserving physical resources required for a GVA meeting. It is assumed these resources may be drawn from any participating domain - under appropriate authorization policies.
NORDUnet Nordic infrastructure for Research & Education Roadmap Short Term – Develop a wire-frame UI proof of concept – Apply the wireframe service to a few urgent activities – Begin the formal process of defining the service requirements Mid term – Initial spec for common service concept (CY2012-Q4 ?) Includes mapping existing standards into the service architecture. – Software design/prototypes for key backend and user processes – in parallel with Service framework: End of 2013-Q1. Long Term Objective: – Broad based adioption on GVA Service Model – A set of standards documents that describe an architecture/framework for a globally scalable, secure, and interoperable video conferencing service – Drive multi-vendor implementations and demonstrate global interoperability – Continuing process to incrementally enhance the GVA Service Model
