COMCAST NGOD PDF
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.

Concurrent Not in Comcast’s VOD Future
The function of the resource allocator is always bundled in a resource manager component. Table 7 — UserParams Element Not needed for default “string”.
The logic may even be multivariate which in this example, would be based on a weighted combination of the load and distance values.
The methods used for allocating network resources such as link bandwidth should be able to scale to complex topologies and large numbers of active sessions. The RTSP specification defines a client state machine as well as a server state machine. Items in such folders are to be excluded from search results displayed on that STB. Devices on the account that can comcasr VOD. Use 1 1 1 July 31, ?
The identifier of a Movie or Preview content file. There are several approaches to resource allocation where one needs to allocate multiple resources in a coordinated set where there is potential contention with other requestors. This document does not include an example session signaling flow showing resources being added or modified in existing sessions.
In this architecture, the Session Manager communicates comcasg each resource manager. Both providerID and assetID or neither.

This is illustrated in Figure 1. Table 23 — GetRootContents Response Post a Comment Read 2 comments. Profile value “BuckRn” changed to “B1. Table 47 — SetResumePoint Request The price that will be billed to the customer’s account. Added expireDateTime to RentalInfo.

Table 1 — Data Items Name account zip deviceID locality Type attribute string attribute string attribute string attribute string Description Subscriber account number. Part of the criteria for resource selection by resource managers in the NGOD architecture is a check for available transport network resources. This can occur due to lost protocol messages or other errors.
Minimal Session Setup Latency The architecture should be designed to result in minimal session setup latency. The next resource manager in the chain allocates its resources based on the parameters of the RTSP Setup 2 request.
Network resource monitoring is a function that provides information on the network connectivity and available network bandwidth between data plane components while network resource allocation reserves network bandwidth between data plane components. Table 14 — TuneAway ActionLink definition At most one, and only if authority is “TV”. Below are a few examples. Typically a folder will contain SelectableItems OR ChildFolders, but there is nothing preventing a heterogeneous folder and it is more likely to occur in the future.
For Barcelona, added to FolderFrame: Table 54 — RatingControl Table 31 — GetEntitlement Response Finally, each resource manager passes the request to the next resource manager based on a list of resource manager addresses that the Session Manager embeds in the initial resource allocation request.
Bandwidth accounting and admission control for edge links connected to Streaming Servers can be performed as part of the resource allocation process of the On Demand Resource Manager while bandwidth accounting and admission control for edge links connected to an Edge Devices can be performed as part of the resource allocation process of the Edge Resource Manager.
The Future of Cable Business Services. The optimal set of resources for an On Demand session request must take into account multiple interrelated factors. Table 43 — SelectionResume Request The use of this field should be limited. To be superseded by SessionStart.
In order to allocate the resources needed for the session request, the Session Manager follows the same process with each resource manager. If it does, available bandwidth for that interface is decremented and the RSVP message is forwarded to the next router along the path.
Will eventually be phased out as system transition to PAID.?
The Session Manager includes an ordered list of resource managers to be contacted for a particular session in the initial resource request. There may be only one. Of the Title Metadata Asset. With deviceId mac address. Instead of coomcast with each resource manager, the Session Manager lets the resource managers themselves negotiate the actual resources to be used for the session.
To reduce the amount of bandwidth that must be provisioned on interior links, the IP transport network connecting Streaming Servers and Edge Devices may be broken into multiple disconnected networks.
This is illustrated comcwst Figure 4. In the process of committing its own resource, each resource manager requests the transport network to reserve network bandwidth between itself and its down stream neighbor and passes the data plane transport parameters for the chosen resource in the RTSP Setup Response. In Gigabit Ethernet environments, disconnected networks can be created by assigning the exterior and interior links of a particular network to a unique virtual routing table in each router in the IP transport network.
Specified max lengths of logoKey and imageLocation to be char. Count positive integer totalResults ngo Appendix III provides details on different algorithms the Session Manager may domcast to select an optimal set of resources given a set of potential resources from each resource manager.
