1 overview In the actual network, many not the same location of the local area network need interactive information, in order to realize the Special wireless network (data chain) and the interconnection between the LAN, and developed the following functions of the gateway. First, IP-level interconnection: That is, the IP datagram of a LAN after the conversion of the gateway through the wireless network to

504 Gateway time-out issues common to Web sites that use Nginx as a Web serverI met this problem when I was upgrading the Discuz forum.In general, this situation may be due to the Nginx default fastcgi process response buffer is too small, which will cause the fastcgi process to be suspended, if your fastcgi service is not good for this suspend processing, then it is very likely to cause 504 Gateway Time-ou

1. The router is also called the IP gateway, and the Gateway Protocol is the protocol for exchanging routing information between gateways.2. Autonomous systems:(1) Autonomous system is connected by the homogeneous gateway of the Internet, autonomous system within the gateway to perform internal

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, and the IP address range for Network B is" 192.168.2.1~192. 168.2.254 ", the subnet mask is 255.255.255.0. In the absence of a router, TCP/IP communication between the two networks is not possible, even if two networks are connected on the same sw

Connect to Sybase through Oracle transparent gateway The transparent gateway technology proposed by Oracle can be used to interconnect with other types of databases to establish connections between different types of data, which is convenient for users to query. Recently, during the implementation of a project in the company, developers need to access some tables in the Sybase Database, and they want to cre

Computer default gateway How to set? This is also a common network setup problem that most new users will encounter, the default gateway of a computer can not be casually specified, must be specified correctly, or a computer will send the packet to a computer that is not the gateway, so that it cannot communicate with other network computers.

RADVISION recently announced that the video interoperability between SCOPIA video gateway for Microsoft Lync and Microsoft Lync 2010 and Microsoft Office Communications Server 2007 R2 has passed Microsoft's qualification. SCOPIA video gateway is fully qualified for compatibility with Microsoft UC Video Solutions. SCOPIA video gateway allows Microsoft Lync 2010 an

, any WAN is much slower than a LAN. This means that the network used by the mobile local client differs greatly from the performance characteristics of the server-side Web application's LAN. A server-side web app can send a large number of requests to the back-end service without impacting the user experience, but the mobile client can only send a small number of requests.• The number of service instances and their location (host + port) are dynamically changed.The service may change over time,

Some websites that run on Nginx sometimes appear "502 Bad Gateway" errors, even when they occur frequently. The following is a small compilation of some of the Nginx 502 error troubleshooting methods, for reference:The reason for Nginx 502 error is more because of a problem with the backend server in proxy mode. These errors are generally not the problem of nginx itself, be sure to find the reason from the back end! But Nginx put these mistakes are in

CenOS gateway encountered a problem when our company used PacketiXVPN. After a long time, I did not solve the problem, so I found out the problem by looking for their technical staff to completely simulate our network environment. it is representative and I will share it with you. Network environment... CenOS gateway problems A problem occurred when we used PacketiX VPN. After a long time, I did not solve

First, the concept of the Gateway: Gateway, also known as the Inter-Network connector, protocol converter. The gateway realizes network interconnection above the network layer, is the most complex network interconnection device, only for two high-level protocol different network interconnection. Gateways can be used for both WAN interconnection and LAN interconne

it?Let's start with some of the things that this architecture needs to do and the shortcomings that exist: first, It destroys the service stateless Feature. In order to ensure the security of the external services, we need to implement the access control of the service, and the Open service control mechanism will run through and pollute the entire open services business logic, This will bring the most direct problem is that the service cluster of the rest API stateless Features.
