I will briefly describe this architecture:Generally, for the convenience of maintenance, the servers of the enterprise website are all in their internal data centers, and only two ports 80 and 443 of the Keepalived VIP address are opened, which are mapped out through the Juniper SSG550 firewall, the Internet DNS corresponds to the mapped public IP address. The firewall and network security of this architecture are described as follows: This system arc

China's cluster routers are widely used and the market competition is fierce. Here we will mainly introduce whether there are variables in the development of cluster routers, including the comparison of the main methods to increase the device capacity at the core layer. Although the current market demand for cluster routers has gradually emerged, there are not many equipment vendors that truly master cluster technologies. So far, only Cisco, Juniper,

As the first technical article, may not be written so detailed, the text will not be so elegant, just because of age, writing technical text is only to prevent oneself forget the previous things and write.Recently, there is a branch of the SSG5 problem, replaced the spare parts after the console, the following situation occurs:650) this.width=650; "title=" 1.jpg "src=" Http://s4.51cto.com/wyfs02/M00/7E/6B/wKioL1b_Jh-yWpzSAAJZFG6SXnA275.jpg " alt= "Wkiol1b_jh-ywpzsaajzfg6sxna275.jpg"/>In fact, th

If there are no interfaces for 10.20.1.0/16, 10.20.2.0/16, 10.20.3.0/16, and 10.20.4.0/16, how can I verify the accessibility of these network segments?Verification:Chablis static route:Static 10.20.3.0/24 discardStatic 10.20.4.0/24 receiveStatic 10.20.5.0/24 rejectConclusion:The configuration of Chablis static route next-hop to discard/receive/reject does not affect

When talking with some friends about Nginx + Keepalived technology, although I have successfully implemented the Nginx + Keepaived project for many times, these are all work with a single-master Nginx, since Nginx is only in the backup state for a long time, we want to put both Nginx load balancers in the working state. In fact, Nginx + Keepalived is also easy to implement. This method is applicable to small and medium-sized websites.Generally, for the convenience of maintenance, the servers of

The first time I heard of the term "self-driving network" was about six months ago, when Rami Rahim, chief executive of Juniper Networks, said in an interview that Juniper was working to implement a network with autonomous capabilities. In his words, autonomous network is like a self-driving car, the network itself not only to have high-performance and powerful functions, all network components can provide

Remember the experiment of sunlight through a prism? The white light passes through the prism and is decomposed into a variety of colors that gradually transition to the color spectrum, followed by red, orange, yellow, green, green, blue, purple, and this is the visible spectrum. It is clear that the prism separates the mixed things. Today's wireless network is like a bunch of white light, users do not seem to feel the difference at the end, but if the white light through the prism to decompose

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

Cisco announced it would check whether the software contains backdoor code After Juniper's firewall product NetScreen finds two backdoors, Cisco announced that it would re-examine its software in case it contains backdoor code. The backdoors of Juniper are considered to be hidden in the elliptic curve encryption algorithm, and the backdoors of Juniper are a secret password for managing access permissions.

In the mobile network, the direct traffic of the base station actually goes to the 6to4 tunnel, that is, we can not see the IPv6 address on the public web. On the other hand, the Internet of things research is very slow, basically is to throw money, can a little research results is the world can count of those it oligarchs.

A company named infoexpress believes that dynamic network access control (dnacc) technology can be used to achieve this. Network Access/Access Control Technology (NAC) generally includes hardware infrastructure or client software designed to protect network security. By using the P2P method, DNA c can change this mode, making it easier to deploy, manage, and adjust the network. Infoexpress, a private enterprise, presented its developed DNA c technology at an InterOP Networking Conference in Las

Edge router positioning is the user from the LAN to the WAN, in the LAN and WAN technology is still very different today, the edge routers shoulder a variety of tasks, simply to meet the needs of users of a variety of business, from simple network to complex multimedia business and VPN business. This requires the edge of the router in hardware and software must have a perfect implementation. The equipment providers have therefore launched a fierce competition, derived from a variety of fresh tec
