....and application components, such as the following defined in CORBA 3.0: # A global Scheduling Service [7, 9, 12] that distributed applications can use to manage and schedule distributed resources via fixed priority analysis and scheduling techniques. 5 # An Audio Video (A V) Streaming Service [13] that facilitates the creation of data, video, and audio streams between two or more media devices. # A Fault Tolerance service [14] that defines a standard set of interfaces, policies, and components to provide robust support for applications requiring high availability. These services augment ....

.... ROUTER EDGE NETWORK B QOSAPI Figure 5: End to end QoS Architecture end to end QoS architecture shown in Figure 5 allows applications to obtain network level QoS guarantees via standard distribution middleware and middleware services, such as CORBA ORBs and the CORBA A V Streaming Service [13]. Moreover, this architecture simultaneously leverages other important middleware benefits, such as platform and protocolindependence. In addition, a middleware centric QoS API can provide additional functionality, such as coordinating the binding of QoS to designated application media streams ....

....a concurrency strategy and an I O strategy. These strategies are decoupled from the protocol handler using the Adapter [4] pattern. In JAWS, this component implements the parsing and handling of HTTP 1.0 request methods. The abstraction allows for other protocols, such as HTTP 1. 1, DICOM, and SFP [18], to be incorporated easily into JAWS. To add a new protocol, developers simply write a new Protocol Handler implementation, which is then configured into the JAWS framework. Protocol Pipeline: This framework allows filter operations to be incorporated easily with the data being processed by the ....

....can perform well over (1) standard Internet protocols, 2) upper layer protocols such as IIOP that are based on the Internet protocols, and (3) off the shelf hardware software. TAO has been used to develop a number of real time applications, including a real time audio video streaming service [59] and a real time ORB endsystem for avionics mission computing [36] The avionics application manages sensors and operator displays, navigates the aircraft s course, and controls weapon release. To meet the scheduling demands of real time applications, TAO supports predictable scheduling and ....
