Over the past few decades, firewalls have been a port-based guardian of the Internet. 　　Now vendors are scrambling to roll out so-called "next-generation firewalls" because these "application-aware" firewalls can monitor and control access based on application usage. In addition, many firewalls have added more and more features to try to discover the 0 attacks, including intrusion prevention systems (IPS), web filtering, VPN, data loss protection, malware filtering, and even threat detection sandbox. For a separate IPs, because of its application control, it may be called "Next Generation IPs" ...

In this article, we will introduce users in the data center cabling project encountered 10 problems and Wu, Zhang Yi and Chen Yutung and other experts to answer. 　　1. Q: On the construction of cable across long distance I encountered this situation in the unit, the office building is too wide, and the Internet access point in the most left of the building, to achieve every floor has Internet access, but also fast, how to solve? Chen Yutung: The balance twisted pair is 100 meters in support of data application, which is defined by international standards. In more than 100 meters of ...

The information construction of petroleum industry has developed rapidly in recent years, and there are up to dozens of kinds of systems including OA, mail, video conferencing and professional application system.　　And the enterprise that carries these businesses internal wide area network mostly uses the special line way with each subordinate branch organization to carry on the networking, for some limited well field as well as some overseas branches also uses the satellite to carry on the networking. Enterprise's reliance on information is more and more high, internal application system and load of data more and more, and the network of special line and satellite is often limited by the bandwidth and the quality of networks, and bandwidth increase ...

Agilent Technology has announced that the Pna-x Network Analyzer's signal source correction noise factor measurement function extends to 43.5 GHz and continues to maintain the highest measurement accuracy of noise coefficients in the industry. 　　The signal source correction technology is built directly on the Agilent Pna-x, providing a comprehensive single connection multiple measurement function to help development and manufacturing engineers develop and test low-noise transistors, amplifiers, frequency counters and transmit/receive modules. Need to perform accurate noise for equipment requirements in aerospace/defense and wireless communications systems.

Tape storage is currently the most affordable, cost-effective storage medium-more backup data, no disk cache. 　　Here are 5 points to improve the performance of tape storage. One of the most important aspects of understanding your tape drive to achieve good tape storage performance is to understand the tape storage drives that you use during the backup process. 　Most modern tape drives are part of a streaming tape drive, meaning they are used to transmit data at a specific rate, so in order for the tape storage drive to work correctly, you must understand its rate and keep its flow state during backup and recovery. ...
