Hardware: Gateway 1: China Unicom ADSL route, wanl port connected to the Internet, Lan1 connected to the switch, and the Intranet ip address of the route: 192.168.20.1 Gateway 2: it is a China Telecom ADSL route. The wanl port is connected to the Internet, Lan1 is connected to the

1. Preface: When the number of hosts in the production environment reaches a certain scale, how to manage them securely requires special attention. Generally, the Secure Gateway product is used before the office environment or the Internet reaches the production environment. I have been using CheckPoint and Juniper for nearly 10 years. The related enterprise-level products of these two brands have a long history and have comprehensive functions. They have been proved professional by many users.

Python gets native IP in a number of ways, each of which has its limitations.Using the Netifaces module to obtain information such as a native IP gateway, you need to install the Netifaces module, whether Windows or Linux can be common.First, the procedure:#!/usr/bin/envpython2#-*-coding:utf-8-*-#实现本地网卡IP # need to install Netifaces module def Getnetworkip (): #获取本地网卡IP地址 importnetifaces #routingGateway =netifaces.gateways () [' Default '][netifaces.af_inet][0] #网关 routingnicname=netifaces.gat

functions of bridges and routers. 5. A relay system above the network layer, that is, a gateway ). When the relay system is a forwarder, it is generally not called network interconnection, because it only expands a network, and it is still a network. High-level gateways are rarely used due to their complexity. Therefore, network interconnection generally refers to the network in which vswitches and vrouters are interconnected. This article describes

system. This is similar to the facade pattern in object-oriented design mode. The API Gateway encapsulates the architecture of the internal system and provides APIs to individual clients. It may also have functions such as authorization, monitoring, load balancing, caching, request fragmentation and management, and static response processing. Shows an API gateway that adapts to the current schema.　　Richardson-microservices-part2-3_api-gatewayThe API Gateway is responsible for service request ro

ObjectiveIt is a long time not to write a blog, recently for a new job, relatively busy, so did not take out too much time to pay attention to my fans write some dry, someone asked me how recently did not update the blog, here to everyone sorry.So, in this article, let's explore the role of API gateways in the entire microservices distributed architecture.BackgroundWe know that in the MicroServices architecture style, a large application has been spli

Gateways aggregate players by region(reprint please indicate the column from Jin Qing)At present, the gateway in the online game system has only played the function of isolating the network and forwarding, at least the journey and KOK3 are the same.According to Yun Hongchun's design concept, the gateway also has a regional aggregation function.Regional aggregation means that many events in the scene are broadcast in the region,The scene server does no

A simple method to configure multiple gateways in WindowsIn a complex network environment, users need to access different network servers through different gateways, such as laptop users using ADSL at home, when using a LAN, you need to switch between different gateways. However, although multiple gateways can be confi

1. Gateway Gateway gateways, English Gateway, gateways differ from routers, gateways can move data between different protocols, and routers (router) move data between different networks. For example, for a voice gateway, it can connect to PSTN networks and Ethernet, which is equivalent to VoIP, which converts analog signals from different telephones to digital si

Label:With its native Oracle 12c installed, the company's platform needs to support both Oracle and SQL Server, often with the need to synchronize data from Oracle to SQL Server. The purpose can be achieved through the SQL Server link server, but because SQL Server is a 64-bit version, it has failed many times. Installing 32-bit SQL Server is also too lazy to toss.Because Oracle is 12c, the gateways installed is also 12c. An attempt was made to instal

For this reason, a simple VPN is used to simulate it. VPN basics:In a private network, the port number can be pulled to the specified server and connected to the specified server in a LAN. After

clients. For example, the Netflix API gateway runs client-specific adapter code that provides the client with the most appropriate API for its needs. The API gateway can also implement security, such as verifying that a client is authorized to make a request. ExampleNetflix API Gateway ResultsUsing API gateways has the following benefits: Hides to the client how the app is partitioned into microservices Provide optimal API to each clien

What are IP addresses, subnet masks, routes, and gateways? Often friends ask me, indeed these terms are often seen by us, today to the people to talk about the meaning of these terms:1.IP Address:The IP address has a 32-bit connection address, consisting of 4 8-bit fields, a 8-bit field called a 8-bit group, and each 8-bit group is separated by a dot to identifyTCP/IP host. Each IP address contains two parts: the network ID and the host ID, the networ
