RPC over advanced network technologies: evaluation and experiences

This paper describes measurements and experiences with remote procedure call (RPC) over different network technologies, and with different levels of functionality. The major basis is the RPC of the OSF Distributed Computing Environment. We first discuss performance based on local area networks; also including secure RPC features. We then present performance results over WAN connections via the Internet and compare them with our findings in LAN settings. Another major focus area is the investigation of the RPC behavior using an ATM network as a basis for transmission. Major limitations and further requirements of client/server interactions in high performance networks are illustrated. The RPC is also evaluated in mobile environments using a cellular, GSM-based WAN. In this domain, various additional requirements have to be considered as discussed in the paper. Finally, steps towards a new integrated and enhanced request-response protocol are pointed out as a conclusion.
