点对多点网络中网络编码存储的调度优势

Scheduling Advantages of Network Coded Storage in Point-to-Multipoint Networks

Ulric J. Ferner, Parastoo Sadeghi, Neda Aboutorab, Muriel Medard

摘要:

我们考虑使用网络编码存储(NCS)的点对多点(PMP)存储区域网络(SAN)的调度策略。特别是,我们提出了一个简单的SAN系统模型,PMP网络的服务器调度算法,和内部和外部阻塞概率的解析表达式。我们指出,选择调度的优势,在NCS系统在正常的操作条件下,内容请求可以暂时拒绝,由于有限的系统容量从驱动器I/O访问或存储冗余限制。由于增加了即时调度选项,NCS可以提高吞吐量和阻塞概率,并补充其他有据可查的NCS优势,如再生,并可用作未来存储系统设计的指南。

英文摘要:

We consider scheduling strategies for point-to-multipoint (PMP) storage area networks (SANs) that use network coded storage (NCS). In particular, we present a simple SAN system model, two server scheduling algorithms for PMP networks, and analytical expressions for internal and external blocking probability. We point to select scheduling advantages in NCS systems under normal operating conditions, where content requests can be temporarily denied owing to finite system capacity from drive I/O access or storage redundancy limitations. NCS can lead to improvements in throughput and blocking probability due to increased immediate scheduling options, and complements other well documented NCS advantages such as regeneration, and can be used as a guide for future storage system design.
