Introduction
COTS (Commercial offtheshelf) middlewares: CORBA, RMI, COM+ Businessoriented QoS requirements: Data persistence, confidentiality, and transactional support. DRE (Distributed Realtime Embedded) systems: Processor allocation, network latency, jitter, bandwidth

Key Technical issues for DRE
Reducing the complexity of managing largescale DRE software Component middleware Realtime QoS requirements Statically: task prioritization, communication bandwidth reservation Dynamically: runtime reallocation reprioritization for handling bursty CPU load.

Component Middleware
Reusable services, create applications rapidly CORBA Component Model CCM Interfaces for collaboration Component strategies via metadata (XML) Persistence Event notification Transaction Load balancing Security

Limitation of DOC
DOC (Distributed Object Computing):
CORBA 2.x (DOC middleware standard) limitations:
Distributed computing + Objectoriented design
Lack of functional boundaries Lack of generic server standards Lack of software configuration and deployment standards
05/16/09
Reza Eftekhari
Component Middleware addresses DOC limitations
Virtual boundary around app component, welldefined interfaces Standard container mechanism, generic component servers Infrastructure to assemble, package, deploy
CORBA Component Model CCM

Limitations of Component Middleware for DRE
Endtoend QoS provisioning
Component server for some resources (thread pools)
Many interacting components
Conflicting policies: high throughput, low latency
Component implementation not right level for QoS provision Endtoend QoS context a priori
Solution: Separating programming and QoS concerns Functional paths: flows of information QoS systemic paths: endtoend interaction, failure detection, recovery
05/16/09 Reza Eftekhari
Static QoS Provisioning
Fixed set of QoS demand Tightly bounded for predictability system functionality Simplest solution available
+ QoS provisioning integral part of component + Decouple QoS provisioning from component functionality Aspectoriented techniques Crosscut multiple interacting components, endtoend QoS behavior
05/16/09 Reza Eftekhari
Static QoS Provisioning with CIAO
QoSenable implementation of CCM Extends TAO (The ACE ORB), support component, endtoend QoS at system assembly Application assembly descriptor QoSenabled containers CPU resources: priority models, priority levels Communication resources: reserving and allocating communication resources, RSVP protocol
Usage: decouple QoS provisioning functionality Compose static QoS provisioning capabilities into the application via the component assembly and deployment phases
05/16/09 Reza Eftekhari
Dynamic QoS Provisioning
Allocation and management of resources at runtime Events triggers reevaluation and reallocation of resources
Dynamic QoS middleware capabilities: Monitor DRE system, detect changes Adapt to change, adjust the resource usage Dynamic QoS abstractions and mechanism for DRE systems Design formalisms: level of service, measured QoS Runtime capabilities: adapt behavior Management mechanisms: dynamic control of resources
