The source code for this package is located in src/gov/nist/sip/proxy. The proxy is a pure JAIN-SIP application: it does not need proprietary nist-sip classes in addition of those defined in JAIN-SIP 1.1, you can substitute the NIST-SIP stack by another JAIN-SIP-1.1 compliant stack and it should interoperate. he proxy can act as presence server and be able to process NOTIFY and SUBSCRIBE requests. If this parameter is disabled, the proxy will simply forward those kind of requests following the appropriate routing decision.

Jitter is extremely important in systems using PLL-based clock drivers. The effects of jitter range from not having any effect on system operation to rendering the system completely non-functional. This application note provides the reader with a clear understanding of jitter in high-speed systems. It introduces the reader to various kinds of jitter in high-speed systems, their causes and their effects, and methods of reducing jitter. This application note will concentrate on jitter in PLL-based frequency synthesizers.

A self-designed control of PC parallel port communication is introduced in this paper.Taking advantage of the MFC ActiveX technology, it is developed in Visual C++ and offset the scarcity of the control of PC parellel paort communication. An example of frequency measurement shows the detail procedure and application of the control.

MemoryMonitor demonstrates the use of the java.lang.management API in observing the memory usage of all memory pools consumed by the application. This simple demo program queries the memory usage of each memory pool and plots the memory usage history graph. To run the MemoryMonitor demo java -jar <JDK_HOME>/demo/management/MemoryMonitor.jar

The sfloppy sample is a super floppy driver that resides in the directory \\Ntddk\Src\Storage\sfloppy. It is a class driver for Super Floppy disk drives. It sits a level above the port driver (ATAPI, USB, etc) in the driver stack, and brokers communication between the application level and the port driver. The floppy driver takes requests from filesystem drivers and then sends the appropriate SCSI_REQUEST_BLOCK (SRB) to the port driver. It is compatible with x86 and IA64 platforms.
