This is 1 the name comacst is presented at the top of the screen. This can occur due to lost protocol messages or other errors. Count positive integer totalResults attribute? Table 10 — ChildFolder Element Prior to revision I03D04, locality has been implemented as a 3-character value composed of decimal digits, corresponding to the ID of the VOD Server responsible xomcast streaming content to a particular household.

It is then up to the Session Manager to further validate all the selected resources for the session. Table 45 — PlayEligibility Response The Session manager may initiate the request to the resources managers in an implementation specific sequence.


String representing the billing vendor for this customer. Use Open Protocols The architecture should enable the use of open, standardized protocols for resource allocation. If there is no XML data returned this will act as an indication that the request was properly processed. This Setup message will specify an IP transport specification including the data plane address of the Edge Device that was chosen for the session.


Required, one or more occurrences allowed. Max of 6 characters. Note that should a request for a resource of a specific type be unsuccessful the Session Manager must retry up to a pre-configured number of times until it is successful.

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

Upon receiving a resource request ngpd the Session Manager the resource manager will hgod a resource from its resource pool that matches the resource requirements specified in the resource request. One consequence of using the optimistic allocation scheme in a parallel manner is that one of the requested resources may not be granted.

The Future of Cable Business Services. If it is unsuccessful, it returns a RTSP Setup response with the appropriate error code indicating the resource was unavailable.

Concurrent Not in Comcast’s VOD Future

Each request has comcazt specific response defined with the request. Table 35 — SearchValidate Request The following sections include example request and response XML documents for illustrative purposes along with tables describing each request field and response metadata field. The following figure illustrates an application of this process. In some cases if an issue occurs a Nav Server Response may comcaet returned.


While IP networks used for the Internet do not manage bandwidth, many MPLS networks do support intelligent path comczst based on available network bandwidth.

Nav Server Response Messsage 9. Resource selectors should only choose resources where the selected IP source can reach the selected IP destination.

This case is more complicated than the ANY: RSVP has been deployed in complex topologies with large numbers of active sessions.

Resource allocation for On Demand sessions is a multi variable problem. If the IP address of the hostname field does not match the address of the resource manager, then it will appear as an RTSP proxy. This priority can be carried as a parameter within a resource request. While each resource manager may have many resources to choose from for a particular session, there may be a small number of resource combinations that meet the routing and resource requirements for the session.
