If you want to provide an iOS program only for use under WiFi network (Reeder), or to provide offline mode (Evernote) in the absence of network status. Then you will use the reachability to implement network detection.The purpose of writing this article Learn what r
can assign different bandwidths to each application on a connection. In addition, the combination of multiple physical connections can provide sufficient bandwidth without a single physical connection. The technology for dividing a LAN into multiple virtual networks was developed and developed by IEEE (International Institute of Electrical and Electronics Engineers) in 1990s. These technologies have been widely used. The IEEE 802.1q standard defines how a single LAN is divided into multiple vir
TCP is the first packet sent by the host during network connection. It is very small but critical. SYN attacks exploit these packets in large quantities. Because these packages cannot be effectively processed, the host or network device cannot be effectively identified. They often need to spend several seconds trying each type of package before giving up providing a normal response. A package takes several
function, so that the FreeBSD system can be used as a gateway that supports Server Load balancer. Because it is implemented by software, it is easy to support non-standard protocols and application-optimized Load Balancing policies, with great flexibility. 3.2 Experiment and Analysis To test the availability of this implementation, we conduct our testing on the most common HTTP protocol. To differentiate different request types, three different types of tests were designed to test the perfo
Use xinetd to manage network application services ■ Li Yang, computing Institute of the Chinese Emy of Sciences This article focuses on how to use the xinetd (Extended super server) mechanism in Linux to manage network application services, and describes how to add and delete
Many companies are upgrading their wireless networks to 802.11n to achieve higher throughput, wider coverage, and higher reliability, while ensuring Wireless LAN (WLAN) to ensure sufficient network capacity and coverage. Next, we will discuss how to use iPerf to measure network performance. This is a simple and easy-to-use
server itself becomes a service bottleneck.In the address translation gateway that supports Server Load balancer, an external IP address can be mapped to multiple internal IP addresses. Each TCP Connection Request dynamically uses one of the internal IP addresses to achieve the purpose of Server Load balancer [3]. Many hardware vendors integrate this technology into their vswitches as a function of layer-4 switching, generally, the Server Load balancer policy is randomly selected and assigned b
