Lecture on Operating System and Network System handles network middleware. Network middleware is a distributed software layer that works above the network operating system and below the application layer and abstracts the heterogeneity of the underlying environment. The role of middleware in network systems will become increasingly important, especially in emerging technology areas such as mobile computing where the integration of different applications and services from different wired and wireless networks becomes important. Since middleware is represented with providing useful building blocks for the construction of software component, the lecture will introduce basic principles, architectures, interactions in distributed systems, and a broad sense of content in the computing infrastructure.
