What is gateway? gateway is also called the inter-network connector and Protocol converter. The gateway is the most complex network interconnection device on the transport layer to achieve network interconnection. It is only used for different network interconnection between two high-level protocols. The structure of the gateway is similar to that of the router. The difference is the Interconnection layer. Gateways can be used for both Wan and LAN int
dynamically as auto-scaling or upgrades occur. In summary, like other service clients in the system, API gateways need to use the system's service discovery mechanism, either server-side discovery or client discovery. The next article will describe service discovery in more detail. Now, note that if the system uses client-side discovery, the API gateway must be able to query the service registry, which is
. Infrastructure services, such as message brokers, typically have a static location that can be specified through an OS environment variable. However, determining the location of an application service is not so simple. The location of application services is dynamically allocated, and a set of instances of a single service can change dynamically as auto-scaling or upgrades occur.In summary, like other service clients in the system, API gateways need
This article gives you a detailed description of how to configure Static Routing using multiple gateways and what operations should we perform? The following article will give us a detailed answer.
Our school has the following network environment. The 450 nodes in the school are divided into five subnets, and the network numbers of each subnet are 192.168.1.0 ~ 192.168.5.0 and all gateways are 192.168.1.1.
Enable a computer with two NICs to have two gateways)
First, we need to declare that it is impossible for a computer with two NICs to have two gateways, because the default gateway can only be one.
Install two NICs for the server, with different IP addresses and gateways (intranet and Internet) respectively. The Internet can be accessed through the Internet Nic,

Gateways: Gateways can be used as a type of translator, abstracting a way to reach resources. A gateway is a binder between a resource and an application.
Like web proxies and gateways that convert between different versions of HTTP, they perform complex logic to communicate between endpoints. But because they are using the HTTP protocol on both si

mirroring and sniffer.For example, when both A and B hosts are connected by a multi-hop router, the gateways are set correctly and a can bePingb, but not on B.PingPass A. You can pass theSwitchDo the mirror, and use sniffer to find out where the ICMP message terminates, what the message content is, you can find the source IP address in the ICMP message is not expected, it is easy to imagine that the NAT function of the router, it is possible to gradu

How can I configure multiple gateways in windows? First, you must write routes in the Windows installation directory.
ProgramThe "route. Bat" file contains the following content:
Route add Target 1 mask subnet mask gateway 1
Route add destination 2 mask subnet mask gateway 2
Route add 0.0.0.0 mask 0.0.0.0 Default Gateway
Destination 1 is the first network number of the route, and destination 2 is the second network number of the route. The subn

How can I configure multiple gateways in a Windows system? First, under the Windows installation directory, write the routing program "Route.bat" file, which reads:
Route Add target 1 mask subnet Mask Gateway 1
Route Add Target 2 mask subnet Mask Gateway 2
Route add 0.0.0.0 mask 0.0.0.0 default gateway
Goal 1 is the first network number for the route, and Goal 2 is the second network number for the route. The subnet mask is a subnet mask of tw
In the more complex network environment, users need to access different network servers through different gateways, for example, when users use ADSL at home, they need to switch different gateways when they use LAN. With the Windows System Control Panel in the configuration of the network, although you can configure multiple gateways, but really effective only on
