英语翻译
– General Inter-ORB Protocol (GIOP):ORB-ORB interactions over connection-oriented transport protocol
– Internet Inter-ORB Protocol (IIOP):ORB-ORB communication across the Internet (TCP/IP)
Advantages of Distributed Object Architecture
• •It allows the system designer to delay decisions on where and how services should be provided It is a very open system architecture that allows new resources to be added to it as required
• The system is flexible and scaleable
• It is possible to reconfigure the system dynamically with objects migrating across the network as required
Weakness of Distributed Object Architecture
• Tightly coupled
– Both ends of each distributed computing link had to agree on the details of the API.A code change to a COM object,for example,required corresponding changes to the code accessing that object.
• Proprietary
– Microsoft controlled DCOM
– Implementing a CORBA architecture typically necessitated the decision to work with a single vendor's implementation of the specification
SOA -- Evolution vs.Revolution
• SOA is developed upon the weaknesses of distribute object computing technique.
– Standard-based
• Reliance upon universally accepted standards provides broad interoperability among different vendors’ solutions
– loosely couples
• Separates the participants in distributed computing interactions so that modifying the interface of one participant in the exchange does not break the other.
Summary
• SOA enables dynamic collaboration among loosely coupled,reusable software components through standard Internet protocols.
•
• SOA is driven by both business and technology needs for open collaboration,cost saving and flexibility to dynamic changes.
•
• SOA is developed from other software techniques including distributed object computing,component-based software engineering,and enterprise application integration.
