content providers such as Google and Facebook, and end users, since 99% per cent of these end-user home routers were developed based on the IPV4 protocol. While transitioning to IPV6, Boko is also deploying load balancers, providing IPV6 translations to public services and retaining IPV4 connections in the internal network. So far, the majority of clients applying for IPV6 services are from education and government departments, especially university research laboratories and government agenci

In the previous articleJuniperSSG140Use PBRAchieve dual-line accessIn this document, we completed dual-line access at SSG140 by enabling the PBR function. However, it was recently discovered that a subsidiary of China Unicom can only establish a VPN with the China Telecom line of the company. As we all know, the communication between China Telecom and China Unicom is not very good, so the VPN delay established in this method is very large, and the maximum latency detected can reach 200 ms.Troubl

, we like this method very much, because after risk and vulnerability analysis is introduced, we can create a unified network topology with best practices for analyzing and fixing solutions. We installed Red Seal software on a Dell server running Windows XP. Once the server is installed and started, the client is installed immediately. After logging on using the client application, we can access a fully functional GUI console server. Both the network consultant and vulnerability consultant must

ASA5585 firewall IDC Data room mounting notes Preface:Currently, online gaming companies use ASA5520. When web websites are often attacked by others, 0.28 million connections are used up, resulting in abnormal services. This problem must be solved immediately. According to the network architecture of many Internet companies, changing the firewall is a good solution. Two brands were proposed to the leader for approval, one cisco ASA and one juniper SR

The news that Apple launched a cheap iPhone to occupy the market is rampant. The Wall Street comments that the next sales boom will be concentrated on relatively cheap smartphones, which puts apple in the dilemma of catering to low-end users or focusing on a few high-end customers; high-end businesses have the largest profits. Apple is the first to release Samsung, the annual flagship Galaxy S4, which has been sold out of stock in the US, according to foreign media reports.Juniper research, a m

Software Introduction Cisco device module gns3v0.7.2 all-in-one tool software, excellent Cisco simulation software, and centralized Juniper simulation!Gns3 is a graphical network simulator that allows you to simulate complex networks. To make the complete simulation, gns3 is closely related to the following software:Dynamips, the core program, allows Cisco IOS simulation.Dynagen. The text-based frontend ends with dynamips.Qemu, general-purpose and

For small and medium-sized enterprises, there are many free open-source router and firewall solutions, and there are even several solutions for large enterprises. Many of them also provide other LAN services, such as virtual private network VPN) servers, hotspot gateways, and forced Network portal captive portals ). This article will introduce some free and open router projects, including those suitable for small and medium-sized enterprises, and even some solutions comparable to Cisco and

What kind of software is Nipper? In fact, Nipper is short for Network Infrastructure Parser. It should be said that it is a Network architecture Parser. Nipper is an open-source network device security audit tool. The advantage of open source is of course its free nature. Previously called CiscoPars, Nipper has a simple interface, but is powerful and easy to install and use. It can accurately complete the promised tasks. Nipper can process network device configuration files, perform security aud

Today we recommend a good open source routing operating system---Vyos, is also my personal favorite of a soft router. Vyos is based on the Debian Gnu/linux, which provides similar operations to other Junos-like iOS, Juniper, and is particularly comfortable to configure, especially with commands such as compare, rollback, etc. Easy to compare configuration and error rollback, won my heart.As a result of the use of Mikrotik RouterOS, in the process of u

providers are developing some technologies and establishing partnerships to help network administrators master IT energy management tools. Both Juniper and Cisco have established partnerships with JouleXr, a non-Agent Energy Management supplier, to monitor, analyze, and control the energy consumption of IT infrastructure and other enterprise devices. JouleX integrates Juniper's Junos Space SDK to monitor and analyze the energy consumption of any devi
