大型多协议服务器的优化网络调度模块设计

Optimization of Large-scale Multi-protocol Server Network Scheduling Module Design

针对多服务器中协议过多,没有形成统一调度方式,传统的网络调度模块存在延迟与冲突的问题,提出一种用于多协议服务器的网络调度模块设计方法。研究了多协议服务器的特征,详细论述了该网络调度模块硬件和软件设计过程。针对多协议造成的网络调度模型发生混乱的问题,运用一种分层约束方法,对不同的底层协议进行分析。实现不同协议服务器的前端测试设备参数约束;再引入一种数据融合方法对多协议服务器外扩FLASH、SRAM、SDRAM存储器芯片和网络控制芯片DM8168进行融合,保证调度的一致性。系统测试结果表明:该模块可以较好地完成多协议服务器的任务调度,网络模块的吞吐量与传统的调度方法提高了13%,模块延迟与冲突下降了5%。

In view of multiple servers in the agreement too much, not form a unified scheduling, traditional net- work scheduling module without delay and conflict problem. A kind of used for multi-protocol network scheduling module design method of the server it is put forward. The study of the characteristics of the multi-protocol server, the network scheduling module was described in detail the hardware and software design process, aiming at multi- protocol network scheduling model of chaos caused by the problem, using a method of hierarchical constraints on different underlying protocol are analyzed. Implement different protocol server constraints on the front end of the test equipment parameters, and a data fusion method is introduced for multi-protocol server extended FLASH, SRAM, SDRAM memory chips and network control chip DM8168fusion, ensure consistency of scheduling. The system test results show that the module can be better finish multi-protocol server task scheduling, network modules throughput increased by 13% , and the traditional scheduling method module delay and conflict fell by 5%.
