GT 3.9.5 XIO

Globus XIO is an extensible input/output library for the Globus Toolkit®. It provides a single POSIX-like API (open/close/read/write) that supports multiple wire protocols, with protocol implementations encapsulated as drivers . The XIO drivers distributed with 3.9.5 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.
