From the users own network maintenance and management, the traditional private network requires the user to maintain a wide area network, high quality and complex equipment and multi-line maintenance and management may also increase the complexity and difficulty, and the heavy workload, the technical staff requirements are very high. In the wide area network users need to invest great energy building, or even a few senior engineers need to invest a lot of work time. But the advantage is that users can control their own routing, network simplicity, reliability, bandwidth is guaranteed. With the reduction in green fees, bandwidth, the result is cheaper for those who have certain technical personnel and funds large and medium business users, the Internet is the main demand for the internal network, combined with network security, performance, reliability, may have higher requirements, They may still choose DDN, FR, ATM and other dedicated networking in order to obtain greater autonomy. Meanwhile, for those very few or even just point to point access point for users to communicate, one or two affordable rental DDN or FR circuit, or even ADSL access network ATM PVC circuit idea is regarded as a simple, a wise choice.
Travel - the shape of Venus with GPS module 55 103 22 mm design, weighing only 22 grams. Positive nearly 2 / 3 are covered by a solar receiver screen, the receiver than the average mobile phone screen screen need to be bigger, so supply of electricity is not a problem. Travel - Venus GPS module size larger than similar products, and therefore also affect the body, after soaring to its portability. In the back of the fuselage with the base ion magnet to avoid turning or braking module will fall. Travel - Venus also uses GPS module SiRF Star III chip generation of efficient, equipped with 4MB Cache can record satellite data. The machine supports wireless transmission distance of 10 meters, and with smart power saving function, that is offline when the Bluetooth interface, more than 20 minutes, the power will automatically shut down. In addition, the aircraft can be an external antenna, and is waterproof to adapt to harsh environments or weather. The new Brocade Data Center architectures to further improve efficiency, reduce costs and greatly reduce the risks of system interruption Brocade announced the Brocade Data Center Fabric architecture to meet the companies want their data centers more efficient, reliable, more adaptable strong urgent needs.
