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.

Max of 6 characters. Devices on the account that can use VOD. These rights may be service entitlements e. Client Implementers take note: The architecture needs to support optimized resource allocation when many potential resources for gnod particular session exist.
This is the name that will be presented to the user at the top of the root folder screen.
Traditional routing algorithms work on a path between two end points with a connected graph in between. A value used by NS to condition navigation results based on locality of the subscriber, e.
This document describes architecture and signaling model for the negotiation of resources between the Session Manager and the resource managers responsible for allocating session based resources.
Because each network is over provisioned, bandwidth accounting and admission for MPEG flows only needs to be performed on edge links. Nav Server Response Messsage 9.
A message describing the condition. Table 4 — NavCheck Response 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. The same title mgod id may be in multiple folders but ngkd have different pricing or availability.
Table 9 — FolderFrame Element Both components MUST be provided, or none.

Of the folder ” ” ‘B1. Each of these state machines is described in appendix A of RFC This phrase means that there may exist valid reasons in particular circumstances ngood the listed behavior is acceptable or even useful, but the full implications should be understood and the case carefully weighed before implementing any behavior described with this label.
Title Asset – A reference to some clmcast content that has a name. It corresponds to the original rental, or the most recent previous resume. HD attribute string “Y” —HD only. Maximum bit rate of the Movie or Preview in bits per second.
D One could apply one of many NP problem optimization techniques to the problem. Table nbod — AddBookmark Request There may be only one. The Session Manager determines the order that resource managers must be contacted based on the order that the MPEG stream must flow through the data plane components that each resource manager controls.
Netscout Video Resource Center. The Session Manager includes an ordered list of resource managers to be contacted for a particular session in the initial resource request. With the introduction of Encryption elements the overall graph would expand to another level. A descriptive name for the folder. Title has been Bookmarked. Attribute string The service ID to use to retrieve an offer for this folder in an upsell or impulse service upgrade.
Folder may be entered. This is comcxst to support existing EPGs and will eventually be phased out. Each of these models represents a different set of tradeoffs between optimal resource selection and session setup latency.
Concurrent Not in Comcast’s VOD Future
The simplest case, set-top, QAM, network and video servers, can be reduced to a unidirectional graph as represented in the diagram below. The displayable resume point, for use with a client, in milliseconds. Concurrent is taking the hit in stride, holding that what it won’t get with Comcast, it can make up via other VOD growth opportunities in North America, as well as budding markets in Europe and Asia.
The title PAID must be specified. This is the TVG list of advisories: The protocol state machine implements the native state machine of the underlying protocol. One consequence of using the optimistic allocation scheme in a parallel manner is that one of the requested resources may not be granted. The Many Faces of Digital Transformation. In the NGOD architecture, the Session Manager manages all interactions between session signaling and resource allocation signaling.
