An implementation framework, including methodologies and the architecture, for a real-time traffic emulation for packet switched networks. The framework uses extended finite state machines to model the traffic flows that are to be emulated. A simple yet flexible FMS-based scripting language is proposed to describe these flows. An event-driven approach to schedule CPU among flows is also adopted.

Reducing code size of debug output statements

A method and system for storing data in data blocks of predetermined size in an electronic memory (e.g. FLASH memory), particularly data such as updatable record of database transactions. The FLASH operates logically as two stacks where data is pushed into either end of the memory in alternating cycles. Between each push or write cycle, a garbage collection cycle is performed whereby only the most recent transaction performed on any particular record is preserved at one end of the stack, while the rest of the stack is made available for new data. When database being monitored is written to permanent memory, the entire FLASH is again made available for new data. If the database is periodically backed up to permanent memory, it can be restored to RAM by reducing the copy from the permanent memory and modifying it according to the record of database transactions in the electronic memory.
