  Two-line access technology for Cisco Routers In some cases, we need to implement dual-line access to ensure stable operation of the network and ensure reliable service quality. The following steps can be taken: 1. Configure the IP address of the

I won't talk about the configuration. Read the previous blog!1. propagation of CE and pe vrf private networksThe IPV4 route in the CE global route table is transmitted to the corresponding VRF route table of PE through the routing protocol (such as

If you want to connect to the Internet through the LAN of the FAST router through a cat, the main device is the router. A router can be divided into a wired router and a wireless router. The biggest difference between the two is that a wireless

The "vro mode" and "NAT mode" in the router connected to the optical fiber have been working for a long time today, which wastes a lot of time and is stuck in the working mode of the WAN interface of the router. WAN: optical fiber, static IP address.

We should all know about VoIP. This low-cost network communication method has always been favored by everyone. As a support for this service, the security of the VoIP protocol is extremely worrying. At present, there are four major security issues

In the previous article, we have explained how to install the Telnet server. Here we will analyze the process of installing the Telnet client. First, let's take a look at the specific environment for running this operation. Install the Telnet Client

We also talked about the SIP Protocol and related SIP protocol stack. In this paper, we propose a software structure and design implementation scheme of the software telephone based on the SIP protocol. this solution is based on the embedded Windows

Network protocols are the foundation of the Internet. Therefore, we need to understand network protocols in many ways and from multiple perspectives. Because of the large number of network protocols, each protocol has its own functions and functions.

DHCP Server Load balancer is particularly concerned in some enterprises. Here, we will provide the Cisco DHCP Server Load balancer solution and provide you with the following reference. In large-scale data exchange over networks, especially for

Google's Gmail has been open for a long time. Its feature is its large capacity, which is now 2 GB. It is a waste of such a large capacity to receive and send emails. Some people who are interested have already used the Gmail plug-in to convert

I. Several networking strategies involved in network convergence Although 3G has been under construction in foreign countries, and some of them are in commercial use and quasi-commercial use, the development of 3G in China and abroad is quite

Over the past few years, the penetration rate of VoIP systems in both the enterprise and residential markets has been greatly improved. VoIP integrates data and voice services into a unified network, which can greatly save costs for enterprise IT

The increasing requirements on network transmission capacity have promoted the further development of the 10 Gbit/s system. The IEEE Institute of Electrical and Electronics Engineers (IEEE) provides a description of the system configurations in LAN)

Over the past decade, the optical fiber industry has made great progress. However, there are a lot of end-to-end technologies, products, processes and programs to choose from. It is very difficult to choose a suitable solution in the application, at

Because the USB signal of the computer is transmitted by cable, the communication distance is difficult to extend, generally not more than 30 meters. The scheme in this paper overcomes the shortcomings of USB signal short distance transmitted by

I read an article about Virtualization of Linux servers over the weekend. This paper tests the performance of several major open-source virtual products, just in line with the isolation performance of several different virtual technologies that I

Hyper-V 3 limits the CPU utilization of virtual machines. Windows Server 2012 is coming soon. The latest Hyper-V 3 brings us more surprises, in the next three blog posts, we will learn about the virtual machine CPU competition mechanism. Part 1: CPU

Home Integrated Wiring management systems are becoming more and more popular. The article focuses on specific construction instances, preparations in the early stage, and precautions during construction, this article comprehensively analyzes how to

This article mainly describes the influence of off-line crosstalk on data center cabling. The out-of-Line crosstalk of twisted pair wires is not a new thing. As early as 10 years ago, some people proposed this concept. At that time, due to the

The development of the network puts forward new requirements for Optical Fiber No matter how the next generation network develops, it will surely reach three levels: the IP address world at the service layer, the light world at the transmission
