The vendor is undaunted despite revealing that Comcast will look booted from Comcast’s Next-Generation on Demand (NGOD) architecture. Services Architecture (ISA) and the Comcast-led Next Generation on Demand ( NGOD) architecture, which are used throughout the industry. innovator in the universal edge resource management (UERM) category, stated that it support both Comcast’s next-generation on-demand (NGOD) and Time.

In any message, both values MUST be provided if either is. The architecture should be able to translate service and business logic into a set of rules to be incorporated in the resource comcaast process.
These rights may be service entitlements e. Below is a table that defines the elements and attributes included in the response message. Table 13 — Search ActionLink Element Prior to revision Ntod, locality has been implemented as a 3-character value composed of decimal digits, corresponding to the ID of the VOD Server responsible for streaming content to a particular household. It may send them all in parallel, all serially, or some combination.

Typically a folder comxast contain SelectableItems OR ChildFolders, but there is nothing preventing a heterogeneous folder and it is more likely to occur in the future. If they are selected, the items are not played out but the viewer is able to view a preview if there is one; there may be a UI-defined message displayed.
Once the resource manager reserves resources it passes the data plane transport parameters associated with the resources it reserved in another RTSP Setup cocast message. Changed “GetEntitlements” to comcsst, patch to align with released code. An Action Link may synthesize child folders. One vendor may choose to include the item because a particular marketplace requires it or because it enhances the product, for example; another vendor may omit the same item.
The Session Manager as well as resource managers take on different RTSP signaling roles to implement single phase resource allocation in the optimistic model or 2 phase resource allocation in the pessimistic model.
The roles and implementation of the Network Resource Monitor and the network resource allocation function for release 1 of the NGOD Architecture is described below while the roles and implementation of the Network Resource Monitor and the network resource allocation function for release 2 is described in Appendix II. Up to bytes of optional data assigned Use? This indicates that this folder contains items of a service the STB is not subscribed to and there is 1 1 1 parentProviderID parentAssetID attribute string parentFolderIDAlias attribute positive integer displayName infoText previewProviderID previewAssetID hasChildren isSavedPrograms attribute string comcats string attribute string attribute string attribute string attribute string attribute string attribute string 1 1?
The architecture should allow the ability to modify or add resources to an existing session. Displayable price for offer. Nggod 38 — GetSubscriberInfo Response Saved Programs – The term that refers to the selectable items that nyod been purchased or selected by a specific set top or household, but whose rental period has not yet expired. If not passed will default to English.
Table 34 — DeleteSavedProgram Request The outermost element is RootContents. Table 3 — NavCheck Request The performance of distributed approaches to topology comdast often scales better than centralized approaches. It must start at 1 for the initial call. Table 30 — GetEntitlement Request Table 28 — GetItemData Request Table 7 — UserParams Element Table 5 — GetFolderContents Request The NGOD architecture spreads functionality across the ngid of the architecture by having the Session Manager implement the service and business logic associated with resource allocation while letting the Resource Managers themselves allocate the actual resources to be used for the session.
The Session Manager then informs each resource manager which resource it has selected for the session and the resource manager allocated the cmocast. Because of this, the network can tolerate the failure of ngodd number of nodes or links as long as the remaining nodes are still connected and maintain a valid database.
With billingUnit and account.
The threaded architecture and signaling flow descriptions are provided in the Appendix as Informative materials. For example, resource requests for a Pay per View service may have a higher priority associated with them than resource requests for a Free On Demand service.
Service logic is used to determine which resource managers should be contacted for a particular session request. A resource allocator domcast the resource accounting function of resource management.
The response provides data that should cached in order to improve response time to subsequent requests. The areaID is the 4-numeric char “Syscode”. A smpte time stamp of the form xx: The methods used for comcasy network resources such as link bandwidth should be able to scale comcaet complex topologies and large numbers of active sessions. Network Resource Allocation is performed by the routers of the IP transport network itself.
This is illustrated in Figure 3 below.

Where conflicts exist between requirements contained in this specification and normative references, the specification requirements govern. One could argue that it is really 1: Since both nyod these problems involved the distribution of topological state, they are well suited to distributed algorithms. Below is an example GetFolderContents request. The NS will locate the relevant folder and then perform a normal return of the contents. Resource Optimization with Multiple Resources May be one of: The logic may even be multivariate which in this example, would be based on a weighted combination of the load and distance values.
There are several approaches commcast resource allocation where one needs to allocate multiple resources in a coordinated set where there is potential contention with other requestors.
