Networking

Nearly every organization utilizes some form of networking to accomplish their goal. These networks can vary in complexity from the typical wired local area network (LAN) used in nearly every office environment to networking for embedded systems to very complex wireless ad hoc networks used to communicate with MACH speed aircraft. By implementing the correct network architecture to optimize for your specific topology, it is possible to optimize the throughput and QoS of your network without paying for devices and systems which are not needed.

Network Operating Systems

The LANsEND network operating system from VOCAL provides a framework for application development of network-connected/internet-enabled consumer devices. It is well featured to support TCP/UDP/IP applications in processors with limited resources (memory and MIPS). The programming model is inspired by Berkeley Unix, with a simple non-preemptive task scheduler, as well as supporting socket network access functions. Such a model is ideal as a "Tiny Unix" (TUNIX) for development of inexpensive network devices for cost-sensitive consumer products.
