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.

This phrase means that the item is an absolute prohibition of this specification. This is the name that will be presented to the user at the top of the root folder screen. Table 2 specifies the order that Resource Allocation requests are forwarded between the resource managers for On Demand services.

Provided for profile “B1. There may be additional HTTP error codes depending upon specific implementation. Each resource manager then modifies the parameters of the request based on the resources that were allocated.

Rules associated with business logic can be translated into parameters of a resource request. Of the Title Asset. Not present for “A25”, “A28” profiles. With billingUnit and account. Indicates the contents of this Child Folder.

While implementing the initial resource selection requests in parallel reduces session setup latency, it also may result in many more resources being reserved by resource managers than is necessary.

Each node keeps a full copy of the topological database. This requires an asset id and provider id. Once the resource managers have reserved resources in response to the RTSP Setup message, the resource commit process starts. The signaling architecture should minimize the number of messages used to set up session and allow as much parallelism as possible between the components involved in setting up the session.


Specified max lengths of logoKey and imageLocation to be char. There are no child folders in SavedPrograms. Applications that receive these response messages MUST be implemented in such a way that they ignore elements and attributes that they are not able to use.

A selectable item is determined by the title asset and the choices of format and language for that title.

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.

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. Table 31 — GetEntitlement Response Table 34 — DeleteSavedProgram Request The format may be modified, e.

Table 13 — Search ActionLink Element When the resource ngos picks a particular resource to use for the session, the comcadt manager commits that resource and frees the others for use in other resource requests.

You will need a free account with each service to share an item via that service. The following table defines the response: The only difference between these interfaces is which components send and receive the messages associated with the interface.

Changes in the topological database are flooded to all nodes in the same topology domain. The construct is considerably extended from the I02 release of this specification.

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. C One could do an evaluation either breadth first or depth first search, determine a path, and then go back and do the reservation. This is illustrated in Figure 4. ENetwork Final Exam Ci Removal of Required Elements and Attributes This is the maximum number of items to be returned.

Each request has a specific response defined with the request. Server processed the request and the NavServerResponse will be in the body. IP networks have traditionally used a distributed approach to both path selection IP routing protocols and managing network bandwidth RSVP.
