The primary goal of the Gigabit Ethernet project is to provide 1Gbps of bandwidth to backbone networks and to provide natural upgrades to existing Fast Ethernet networks, while leveraging existing network management tools and training as much as possible. In order to maintain the maximum collision area of 200 meters in diameter, the

Channel technology. 8 B10 NRZ (not normalized) encoding method is used to provide a valid baud rate of 1.25Gbaud. Therefore, it can provide a data rate of 1 Gbps at full speed.The 1000BASE-SX series uses low-cost short-wave CDcompact disc, optical disc lasers) or VCSEL (Vertical Cavity Surface Emitting Laser) transmitters, while the 1000BASE-LX series uses relatively expensive long-wave lasers. The 1000BASE-CX series intends to connect high-performan

ObjectiveIn the past few weeks, I have investigated and researched the security of GSM in many aspects, such as the loopholes in GSM communication protocol. In addition, I have a security audit of the most widely used BTS software in the world today. In this article, I'll show you a few of the vulnerabilities I've found in this open source product that will allow an attacker to invade the base station transceiver (BTS) and remotely control its

KM algorithms are generally used to find the best matching of binary graphs.Steps:1. Initialize the feasible benchmark2. Use the Hungarian algorithm to judge the newly added points3. If you are unable to add new, modify the feasible benchmark4. Repeat the 2.3 operation until you find an exact match for the equal sub-graph.Summary of each step:1. Establishment of 2 feasible benchmarks according to the dichotomy chart;LX is the feasible benchmark for X,

GBIC is the abbreviation of Giga Bitrate Interface Converter, is an interface device which converts gigabit electrical signals into light signal. The Gbic design can be used for hot-swappable. The gbic is an interchangeable product that conforms to international standards. Gigabit switches designed with GBIC interfaces are flexible and have a large market share in the market. Cabling Specifications for Gbic ports The following table shows the cabling specifications for the GBIC for Cisco produ
