This a script for working with short TCP files with several source nodes, sharing a single bottleneck link. It is used to show how with proper choice of CIR, marking decreases losses of vulnerable packets (syns etc).
自制51編程器
I have build my own programmer. This device can program the AT89C51 and works with it. So it can easily be adapted to programming other devices by itself.
The Atmel Flash devices are ideal for developing, since they can be reprogrammed easy, often and fast. You need only 1 or 2 devices in low cost plastic case for developing. In contrast you need 10 or more high cost windowed devices if you must develop with EPROM devices (e.g. Phillips 87C751).
The LT® 1529/LT1529-3.3/LT1529-5 are 3A low dropout
regulators with micropower quiescent current and shutdown.
The devices are capable of supplying 3A of output
current with a dropout voltage of 0.6V. Designed for use
in battery-powered systems, the low quiescent current,
50mA operating and 16mA in shutdown, make them an
ideal choice. The quiescent current is well controlled it
does not rise in dropout as it does with many other low
dropout PNP regulators.
