traditional Internet backbone network and achieves high efficiency. Performance Tests on hosts in two supercomputing centers show that the peak rate of UDP packet User datasync Protocol packet reaches 133 Mbit/s, it is very close to the theoretical peak rate of the IP packet transmitted on the ATM OC-3 135 Mbit/s ). In order to reduce network complexity and improve reliability, MCI also plans to change the PVC mesh connection between routers to SVC in 1997.

modules form different components. The implementation model view is primarily intended for use by developers .
The Environment Model view is used to describe the hardware topology of a physical system. For example, the distribution of computers and devices in a system and how they are connected, where computers and devices are collectively referred to as nodes. In UML, the Environment Model view is represented by a deployment diagram. The system de
allocations and releases can cause memory fragmentation.
In C + +, the number created on the heap is accessed using pointers, and memory is allocated with new or malloc.
If the requested buffer is too large, the application may fail.
It is recommended that you use the heap when you do not know how much data will be needed during the run time or when you need to allocate a lot of memory.
May cause a memory leak.
