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.

Clients representing STBs must migrate to a 5-character value which suffixes the 2-character peer group designator. Work with Heterogeneous Transport Networks The architecture should support video comdast networks that are not fully connected. Nav Server Response Messsage 9. Post a Comment Read 0. In this signaling example, each resource manager has more than one resource to select from for the resource request.

As the RTSP Setup Response is passed back through the cimcast, each resource manager examines the resources that were committed by its up stream neighbor. It will serve as a basis for testing requirements. Each of these models represents a different comcasg of tradeoffs between optimal resource selection and session setup latency. If any ngo along the path does not have enough bandwidth to service an RSVP request, the router fails the request and the message is returned along the same path that it was originated from, tearing down existing state long the way.

Comcsat time for display Run time for calculations – format is HH: The NS response to a message is conditioned by the profile value, i. This can occur due to lost protocol messages or other errors.

Corrections and clarification on “Geo” element GetSubscriberInfo. Flexibility to incorporate new Resources, Resource Managers The architecture should make it possible to incorporate new classes of resources along with new comcazt managers without having to make major modifications to other components of the system.


Of the folder ” ” ‘B1. To allow the NRM to understand bandwidth availability, the IRP must include bandwidth availability as part of the link state attributes that are flooded. 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.

Nfod listing EPG data is not included. This indicates the customer is not allowed to view this item.

Once the comcsat manager determines its role in the signaling flow, it examines the parameters of the RTSP Setup message it received to determine which resources it needs to allocate for the session. The id number of the predefined query.

N, where the set-top is the end point and the other is a set of video servers. These parameters include the optional elements in the response schema that be included in the actual response and the maximum number of items to be returned.

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.

Table 2 specifies the order that Resource Allocation requests are forwarded between the resource managers for On Demand services. This indicates the user can watch this item freely. Scale with Large Networks As On Demand Services become more popular, the number of potential resources that may be used in a particular session may grow very large. Table 16 — RentalInfo Element Table 32 — AddBookmark Request Where conflicts exist between requirements contained in this specification and normative references, the specification requirements govern.


The following examples illustrate several of these. Must be supplied if the account is supplied. Added presentationType to FolderFrame Barcelona only. Added element GlobalAlias to SelectableItem. A folder may have rights associated with it that limit a client’s ability to view or select the contained. Value is zero if parent is the root folder.

Profile value “BuckRn” changed to “B1. Threaded Signaling for Pessimistic Resource Allocation This section provides example signaling flows based on the threaded architecture. The list of Streaming Server ports and QAMs that nfod be used for this request may be further reduced when the connectivity and available bandwidth of the IP transport network is taken into account.

Where the probability of success is ntod high, then Optimistic Allocation schemes can provide a faster allocation scheme than a pessimistic scheme. The provider id of the preview asset if applicable. If present, values are ‘UA’ or ‘UD’. Since AssetIDs are always char. One of the functions of ngdo component called the Session Manager is to determine which resource managers are required for a particular session request and to communicate with the resource managers to allocate the resources required for the session.
