GT 4.2.1: XIO

Globus XIO is an extensible input/output library written in C for the Globus Toolkit. It provides a single API (open/close/read/write) that supports multiple wire protocols, with protocol implementations encapsulated as drivers. The XIO drivers distributed with 4.2.1 include TCP, UDP, file, HTTP, GSI, GSSAPI_FTP, TELNET and queuing. In addition, Globus XIO provides a driver development interface for use by protocol developers. This interface allows the developer to concentrate on writing protocol code rather than infrastructure, as XIO provides a framework for error handling, asynchronous message delivery, timeouts, etc. The XIO driver-based approach maximizes the reuse of code by supporting the notion of a driver stack. XIO drivers can be written as atomic units and stacked on top of one another. This modularization provides maximum flexibility and simplifies the design and evaluation of individual protocols.
