- Efficient Dbuffer Model

The buffer model is designed to reduce the frequency of memory copying. At present, there are two famous Buffer models, mbuf (a 2 tires scheme, used in FreeBSD) and STREAMS (a 3 tires scheme). The Juphoon Dbuf (Data buffer) model is designed more efficient for protocol process, and it provides two different buffers for data and structure respectively. The result of using Juphoon Dbuf is, there would be no real memory copy while data is passed between different protocol layers.

- Safe & Efficient Memory Bucket

Juphoon Memory Bucket, which features high performance and stable request, is designed for memory management, especially for that of an embedded system. The Bucket object can allocate memory blocks of different sizes to satisfy the requirements of upper applications and set magic data in the memory blocks to prevent invalid memory usage at software development phase. It can also prevent the underlying OS from allocating and freeing memory.
