Consolidating Servers Same motivations for multiprotocol servers Higher risk to use a single, multiservice server, why? Consolidating many services into a single server process reduces the number of executing processes dramatically The total code required

How applications become clients by initiating communication How applications use TCP or UDP protocols to contact a server How they use socket calls to interact with the protocols CSIE, NTUT, Taiwan

Transport layer protocol is to reate a process-to-process communication Provide control mechanisms Provide a connection mechanism for the processes

Introduction This chapter describes the general concept of remote file access and reviews the concepts underlying a particular remote access mechanism Because the remote file access mechanism derives many ideas and details from the underlying OS, the chapter reviews the Linux file system and the semantics of file operations

Introduction X Presents the sequence of steps a programmer takes to first create a conventional program and then divide the program into local and remote components w Uses an example application to show the output from rpcgen and additional code required to create the client and server components of a distributed program that uses rpc
