OACE Product Standards

• Goal is for portability of Application Programs
• Strongly prefer interoperable standards-based
  real-time products
• Not clear how far standards will take us
• Some Tech Areas do not have mature standards
• Distribution middleware - Group Ordered
  Communication
• Resource Management
• Initial OACE specification approach is to
• Utilize standards where mature standards have
  proven worth
• Specify infrastructure products where needed
• Migrate towards standards as they mature
• Utilize adaptation layers where this aids
  portability
