Blue Share is a collection of applications, daemons, and libraries that work together to provide a robust subsystem for peer to peer network file sharing.

These components are architected to execute in both real and protected modes. In real mode, all components operate in the same address space. In protected mode, some components are separate processes that operate in their own
address spaces, while other components are shared libraries that can be bound to multiple application processes. Components in each process communicate with each other through shared memory.

Blue Share takes advantage of a flexible architecture that allows for maximum function with highest performance and smallest footprint. See the sidebar for a detailed discussion of the Blue Share architecture.
The CIFS Client supports connections to a remote server through NetBIOS or directly through TCP. It also negotiates session parameters, authenticates, mounts shares, dismounts shares and terminates sessions. The CIFS Client maintains a file context and also performs all file operations.

The CIFS Server exports shares to a network and accepts connections from remote clients through NetBIOS or directly through TCP. Authentication can be disabled, or can be offloaded through a GSSAPI interface to an authentication server such as Kerberos.

NetBIOS provides name registration and lookup in Microsoft networks. Name registration or lookup can be performed using broadcast packets on a local network, through a WINS server somewhere on the network or a combination of both.

Blue File is a flexible file API redirector that allows easy integration with the target file systems, provides alternative APIs, and allows support for LAN Manager virtual file components.

The Platform Abstraction layer enables easy ports to any hardware and software platform. Hardware and RTOS abstractions are provided as well as portable utility functions used across Blue Share components.
