Abstract:
Message oriented middleware is being used as an advanced enterprise application integration tool. It can establish reliable asynchronous communication sessions between distributed application objects. In such enterprise communications, guaranteed message delivery is critical. In this paper, we consider message queuing communication on an MPLS VPN. In client VPN sites, a large amount of data is generated by computers and it is stored in the local message queue. Then data is processed, filtered, and sent to the remote message queue in the server VPN site. In the server VPN site, stored messages are dequeued and sent to the business application or database servers in the server VPN site. The data generating processes in the local VPN sites may be different. Data may be generated explosively during a short period in some local VPN sites. It is necessary to utilize the message queue resources in the whole VPN efficiently in order to avoid an overflow of messages and to guarantee the messa
ge delivery during such a bursty period. This paper describes a traffic control scheme that can adaptively change the rate at which data is sent from the local message queue in the VPN site to the remote message queue in the server VPN site. We created a OPNET simulation model that can precisely simulate the above control scheme on an MPLS VPN and showed its effectiveness through simulation studies.
