Display as a normal folder. This is the name that will be presented to the user for navigation. 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 ngoe.

The proxy signaling model enables resource managers to efficiently negotiate the optimal set of resources to be used for a session using a minimal number of message exchanges.

This indicates that this STB is not subscribed to the service this item is a part of. Not comxast in profile “B1.

In the threaded architecture, the resource selection function is distributed to the resource managers themselves.

Since the resources are typically spread over a narrow concast, then the probability of simultaneous requests are low. Table 31 — GetEntitlement Response Maximum bit rate of the Movie or Preview in bits per second. Table 16 — RentalInfo Element The NGOD architecture spreads functionality across the components 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 comcwst used for the session.

A QP comprises parameters that condition the results of a query.

For example, it may be more important to fulfill resource requests for sessions associated with a pay per view movie service than for sessions associated with a free On Demand Service. Of the Title Asset String indicating the location of the client.

This results in an architectural goal to use a single protocol for all resource signaling between the session manager and resource managers. Comcast is not responsible for any liability of any nature whatsoever resulting from or arising out of use or reliance upon this specification by any party. This is the maximum number of SelectableItems that will be returned. Table 33 — DeleteBookmark Request 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.

To simplify implementation and migration to future releases, IP addresses for head end components in release 1 should be allocated from a single address pool independent commcast the number of disconnected networks that are provisioned. This is an indication that some condition occurred that prevented the expected response from being returned.

It is suggested that they receive all ActionLinks, and use the values provided to decide whether or not to present a particular action link to the user. If absent, English audio and no sub-titles. When a routing protocol such as OSPF is run in an environment such as this, there will be a separate link state database maintained for each network.

These rights may be service entitlements e. The protocol state machine implements the native state machine of the underlying protocol.
