OOMWorks - Introduction

• OOMWorks is a 3 year old company that provides
  research and development services in the field of
  Distributed, Real-time, and Embedded (DRE)
  applications.
• OOMWorks provides advanced research and value
  added enhancements in middleware platforms. This
  enables the vertical and horizontal integration
  of DRE applications using standards based
  solutions. OOMWorks' expertise allows its
  customers to significantly reduce the
  time-to-market and lifecycle costs of
  applications.
• OOMWorks was formed with the vision of building
  crucial middleware infrastructure for DRE
  applications. By providing next-generation
  distributed computing infrastructure, we enable
  the path for applications of the future.

Real-time CORBA and Dynamic Scheduling

• Fixed Priority Scheduling
• RT-CORBA improves predictability by
• Bounding priority inversions
• Managing resources end-to-end
• Configuration/control resources
• Processor Resources
• Thread pools
• Priority models
• Portable priorities
• Communication Resources
• Protocol policies
• Explicit binding
• Memory Resources
• Request buffering

Distributed Dynamic Scheduling

• Problem
• Tasks in the system may not be known
• Execution time and QoS requirements of tasks
  change dynamically
• Tasks span multiple heterogeneous hosts
• Tasks and hosts they span are not known a priori
• A priori scheduling analysis may not be possible
• Task scheduling requirements may need to be
  propagated across hosts it spans
• Need to support custom scheduling discipline
  plug-ins
• Distributed task cancellation requires
  rescheduling on hosts it spans
• Local schedulers must collaborate to ensure
  global scheduling

• Solution
• RT-CORBA 2.0
• Scheduling Segment is a sequence of code with
  specific scheduling requirements
• Distributable Thread (DT) a programming model
  abstraction for a distributed task
• DT scheduling information passed through GIOP
  Service Contexts across hosts it spans
• Pluggable Scheduler facilitates the use of custom
  scheduling disciplines
• Scheduling Points define places where application
  and ORB interact with the scheduler

Differentiated Services (DiffServ) in TAO

• Provides efficient and flexible setting the DSCP
  codepoints in ORB data packets
• Done by extending the RT-CORBA protocol
  properties
• Setting the DSCP codepoint in the message sent
  and the reply received
• Map RT-CORBA priorities to the DiffServ network
  priorities

QoS Enabled Audio-Video Streaming

• Standard Mechanisms for
• Stream establishment
• Stream control
• Quality of Service
• Multiple flows
• Multiple Protocols
• Incorporates multiple network QoS mechanisms
• RSVP
• DiffServ
• SCTP
• RTP
• SFP

IntServ (RSVP) Reservations for A/V Streaming

• AQoSA targets (RSVP) Resource ReSerVation
  Protocol
• RAPI GQoS
• Allows application to specify and request QoS
  uniformly and portably
• Updates itself based on QoS notifications
• Be notified if the QoS is no longer available

  component assemblies to component servers
• Goal to separate configuration concerns into
  aspects
• Server configuration
• Object/service configuration
• Application configuration
• Object/service deployment
