Want to test the cache server to run 2G of traffic to see. Try to let your IP scheduler to the server on the original basis, add 20% weights, so the request will be more on the original base of more than 20% of the amount. Originally the whole machine is basically floating in 800m-900m. So you have to use another network card to run, do not want to bind. This time, because of the new regulation, it has been monitoring its performance.
It's obvious that the back is getting bigger and
determine whether the filter is to be executed. We can use this method to specify the effective range of the filter.
Run: The specific logic of the filter. In this function, we can implement the custom filtering logic to determine whether to intercept the current request, not to follow the route, or to do some processing after the request route returns the result.
Zuul defines four different filter types by default, overwriting an external HTTP request to the API
in the daily work and life, some friends will buy back the router generally have to change the default gateway, this is also for security reasons. Today we are working together to discuss the method of changing the default gateway 192.168.1.1 to 192.168.0.1.
1, landing router Web management interface, ie browser in the input of 192.168.1.1, the User name and password box will be pop-up, the default is gen
502 Bad Gateway Causes
A server (not necessarily a Web server) is a gateway or proxy to meet customer requirements, such as a Web browser or our Checkupdown robot, to access the requested URL. This server received an invalid response from an upstream server to fulfill its requirements.
Meaning
This usually does not mean that the upstream server has been shut down (no response
With the continuous development of the network, the manufacturing industry is also out of the traditional business model, the network has become the core of enterprise operation. The manufacturing industry can use the network platform, not only can realize the enterprise internal information exchange and the sharing, but also may use the network power, the application in the production, thus greatly enhances the production efficiency. However, in the continuous expansion of the network architect
Recently wrote some articles about the gateway, said to be written, rather than copy, before the firewall, encryption machine, network gate, VPN security gateway and other related equipment, can say just heard, nothing in-depth understanding. This time, in order to write a cryptographic machine operating norms, and the network gate operating norms, it is a charge of the strength of the breast. Finally, it's

Some people often ask me this question "how to enter the intranet" and how to answer it. In summary, it is a sentence "break through the gateway and use port redirection to enter the intranet ".
The first choice is to break through the gateway (GetWay), which is easy to understand, because an intranet must always access the internet through the gat

Article title: Build a WAP gateway on Linux (basic ). Linux is a technology channel of the IT lab in China. The most popular technology that includes desktop applications, Linux system management, kernel research, embedded systems, open source, and other basic categories to implement mobile services is Wireless Application Protocol (WAP ). The open-source gateway for WAP implements protocol conversion betwe
From: http://www.kelenao8.cn/u/space.php?uid=3do=blogid=26 Gateway (gateways) refers to the communication between different networks of equipment and procedures, is an important component of network connectivity equipment, It not only has the function of routing, but also can transform between two different protocol sets, so that different networks are interconnected. For example, a NetWare LAN can access IBM's SNA network through a
In the market economy, the contradictions in the field of information security are particularly prominent. Viruses and anti-virus, hackers and anti-hackers, spam and anti-spam messages are always intertwined, and this is a long way to push the safety industry wheels forward.
With the continuous application of cloud computing and virtual technology, spam Mail has broken through the traditional form of transmission, and gradually locked the target in the enterprise mailbox. In the face of such a

Generally, all hosts in the same CIDR block have the same default route with the gateway as the next hop. When the gateway fails, all hosts that use the gateway as the default route in this segment cannot communicate with the external network.

Introduction
1. About the SIP protocol
Currently, there are three basic communication protocols based on VOIP: H 323, SIP, and MGCP. The following describes the comparison between the H 323 protocol and the SIP protocol.
H.323 was proposed by ITU. It attempts to regard IP phones as well-known traditional phones, but the transmission mode is changed from circuit switching to group switching, just like analog transmission to digital transmission, and coaxial cable transmission to optical fiber tra

The security technology of IPv6. Although IPv4 network security is a common problem, it is also a problem to be asked. Now let's talk about the IPv6 Security Gateway information. Now let's take a look at the specific content.
IPv6 provides many transition technologies to achieve this gradual process. These transition technologies mainly focus on solving two types of problems: IPv6 isolated island communication technology-to achieve interconnection bet

So what exactly is a gateway? A gateway is essentially an IP address of a network to another network. For example, network A and network B, network A's IP address range is "192.168.1.1~192." 168.1.254 ", the subnet mask is 255.255.255.0; The IP address range for Network B is" 192.168.2.1~192.168.2.254 "and the subnet mask is 255.255.255.0. In the absence of a router, TCP/IP communication between the two net
