迁移工作流系统中MI间的通信研究

Study on communications between MIs in migrating workflow system

提出了一种新的迁移实例(MI)间的消息通信机制,该通信机制简化了寻址步骤,解决了邮件的失效处理以保证邮件的可靠性,而且通信阶段不再限制MI的自主移动。同时还支持MI邮件的保序,并基于邮箱分离策略实现了MI迁移状态邮件的异步处理,在对邮件进行正确性及完整性验证的基础上,支持错误邮件的重新传送。

A new message communications mechanism between MIs was brought forward. The communications mechanism can simplify the address searching procedure and solve the invalidation of the mails to keep the accuracy of the mails so that the MIs can move on their own without being limitted at the communications phase. It also can keep the sequence of the MIs＇ mails, and based on the mailboxes＇ separation the mails can be dealt with while the MIs are moving. Furthermore, the inaccurate mails can be sent again through verifying the accuracy and integrality of the mails.
