packet tracer network design

This article describes the design and implementation of QoS support in Linux 2.4.x kernel, and detailed analysis of the default packet scheduling mechanism pfifo. In traditional TCP/IP routers, all IP data packets are transmitted using a FIFO (first-in-first-out) mechanism. In the early days when the network data volume and key business data volume were not larg

Article Title: design a Secure Linux network. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. As a system, its security should be carefully considered when planning the network topology to formulate security policies. After th

switches from the backbone layer and the aggregation layer of the initial Network center to the access layer of the network edge.first, the third layer of exchange technology1, three-layer switching conceptThe third layer of switching technology, also known as IP switching technology or high-speed routing technology, is relative to the traditional concept of exchange proposed. As we all know, the tradition

. You can also use layer-2 networking for certain functional partitions. Device High Availability design Equipment reliability is the most basic guarantee of system reliability. It is particularly important to ensure the reliability and stability of the equipment in the core exchange area of the data center. Although the failure probability and impact scope of core equipment can be reduced by adjusting and optimizing the architecture, strategy, and co

Java Socket Network programming heartbeat design Concept1, generally used to determine the other side (equipment, process or other network elements) is normal movement, the general use of timing to send a simple communication packet, if not received in the specified time period of response, the other side has been take

SPC gateway interfaces through normal routing. According to the design process, packets entering the network outside the wireless network will be routed according to the destination address, and will inevitably be routed to a SPC gateway interface. In summary, when SPC receives an IP packet, it processes the

First, rewrite the buffer on the C # side to verify that the C # display control is normal. See figure 2 for debugging.
