面向容器级多变体的Mimicveth网卡设计与实现

Design and Implementation of Mimicveth Network Card for Multi-variant Containers

聚焦于容器级多变体执行(MVX)过程,针对容器级多变体系统分发时存在容器不能一对多通信、报文信息不匹配和TCP协议握手失败的问题,以及表决时存在报文时序乱序和报文分段分片问题,提出一种基于Mimicveth网卡的多变体系统网络输入输出(I/O)分发表决方案。该Mimicveth网卡为分发代理、执行体、表决器之间建立一对多双向传输通道。实验验证,依托该Mimicveth网卡能够有效实现容器级多变体系统分发和表决,改善容器级多变体系统可用性,为后续面向容器的多变体系统研究发展提供了原型基础。

Focusing on the multi-variant execution process for the container,a network input/output(I/O)distribution and voting scheme for container-level multi-variant systems based on Mimicveth network cards is proposed to solve the issues of one-to-many communication between containers,mismatched message information,and TCP protocol handshake failure during distribution,as well as the problems of packet timing disorder and packet segmentation and sharding during voting.This Mimicveth network card establishes a one-to-many bidirectional transmission channel between the distribution agent,the executor,and the voter.The experiment verifies that this Mimicveth network card can effectively realize the distribution and voting of container-level multi-variant systems,and improve the availability of container-level multi-variant systems,which provides a prototype basis for the subsequent research and development of container-oriented multi-variant systems.
