Client-Server programming over TCP and UDP

Horizon Network Security has extensive knowledge and experience in designing and implementing client-server applications. Some of the most recent projects have included.

NASA

We developed a payload tracking system that is used on all shuttle flights.

Network Attached Storage Company

Working with their internal staff, a client-server configuration process was created that features over 800 discrete functions. It includes Service Advertising Protocols, server-to-server communications, transaction semantics for ensuring complete configuration changes, and advanced self monitoring features that include memory leak detection, system failure interception and recovery and 'call home' abilities to report serious problems.

Phone Company

We worked with the cellular billing department to create a system that tracks a cellular users account activity to ensure accurate billing. This system had the advanced feature of being able to be upgraded while running without any loss of data.

Child Care Company

We developed and deployed a video room monitoring system that allows parents to witness the activities of their children via a web site. The system was deployed over DSL network services using the UDP protocol to avoid scalability issues encountered with TCP.
