The resource manager determines its role in the signaling flow and attempts to allocate the requested resource. Use 1 1 iconID attribute number 1 queryID attribute number 1 5. RSVP has been deployed in complex topologies with large numbers of active sessions.

The identifier of a Ngood or Preview content file. The Session Manager examines the resource descriptors in the SARR message which determine which type of resource managers need to be consulted in the resource allocation process.

Table 50 — GetUpsellOffer Request Future release the NGOD architecture distributes the function of network resource reservation using RSVP as a signaling protocol to reserve network resources. For each Title, a SelectableItem element will be present. Please refer to the Nav Server Response definition later in this specification. This is a based on a breadth first search. To achieve this goal, it is best to design then architecture in such a way that functionality and the resulting processing requirements are divided as evenly as possible between components.

Must be 1 present and at least one of the attributes must be present. When pessimistic resource allocation is implemented in the threaded architecture, both resource allocation and resource selection are implemented in the resource managers. Note that should a request for a resource of a specific type be unsuccessful the Session Manager must retry up to a pre-configured number of times until it is successful.

Added presentationType to FolderFrame Barcelona only. If it does, available bandwidth for that interface is decremented and the RSVP message is forwarded to the next router along the path. In some cases if an issue occurs a Nav Server Response may be returned. The providerID of the title asset to be resumed.

Rules associated with business logic can be translated into parameters of a resource request. If the IP address of the hostname field does not match the address of the resource manager, then it will appear as an RTSP proxy. In a single transaction it specifies the resource and the resource manager either denies the resource request or completes the implicit reservation and commits the resource. Network Resource Allocation is performed by the routers of the IP transport network itself.

VOD Navigation Messages 2. RatingControl Element If an STB has parental control values set, then folders that may contain items with ratings more restrictive than those control values should be inaccessible and “grayed out” for that STB.

One consequence of using the optimistic allocation scheme in a parallel manner is that one of the requested resources may not be granted.

Required if the attribute startAt is present. If it is unsuccessful, it returns a RTSP Setup response with the appropriate error code indicating the resource was unavailable. Display as New “P”: There are a couple different models that can be used to implement resource allocation. Table 21 — Chapter Element A TVG source id.

Value is zero if parent is the root folder. Common Elements and Attributes Added “account” and “zip” as optional elements in several requests. The Session Manager uses interface S2 to obtain authorization for the request and to obtain the list of assets and the required bandwidth for the session from the Purchase Server.

Behind the Scenes at Sprint’s 5G ‘Split’. No final decisions have been made but, unlike wine, VOD gear doesn’t improve with age. This is the TVG list of advisories: Client Implementers take note: The displayable resume point, for use with a client, in milliseconds.

The models used to implement resource allocation algorithms for the Next Generation On Demand architecture must take these inter-related dependencies into account.
