Differences among hubs, switches, routers, reconnections, gateways, and bridges 1. a hub, also known as a HUB, works on the first layer of the OSI Layer-7 structure and is a shared-bandwidth device, receives data broadcast. Generally, the LAN uses a Star Connection topology, and each workstation is connected to a hub. Because of the bandwidth sharing feature of the hub, the network utilization efficiency is extremely low. Generally, the hub is not use

This article mainly introduces the logic judgment of js for IP addresses, subnet masks, and gateways. If you are interested, refer to the js verification for static address configuration, I found a lot of information about ip addresses and masks on the Internet. I didn't have ip addresses, submask, or gateway logic judgments. I wrote my own code for reference. Common knowledge about Gateway addresses: First:And calculate 1 and 1, and 0 are 0, 0 and 0

vswitches above Layer 3 Have VLAN functions and can also be divided into broadcast domains, communication between subbroadcast domains is not allowed, and communication between them still requires routers. (4) A Router provides firewall services. It only forwards data packets of a specific address. It does not transmit data packets that do not support the routing protocol and transmits data packets of the target network, this prevents broadcast storms. 4. Gateway: we have analyzed the three mos

Uid = 3 Do = Blog id = 26 gateway refers to the communication interface device and Program Is an important part of the network connection device, It not only provides routing functions, but also converts between two different protocol sets. To interconnect different networks. For example, a Netware LAN can access the ibm sna network through a gateway, so that a PC using the IPX protocol can communicate with an IBM host on the SNA network. Router (rou

ConceptGateways are in two systems that use different communication protocols, data format structures, languages or systems, computer systems or other devices that act as converters, gateways and bridges are not the same, bridges only pass data between two systems, do not perform conversion operations, the gateway repackage information, or change the syntax of the data. To conform to the requirements of the destination system, the gateway can also be

microservices environment.By 2016, Netflix already had 8300+ subscribers, playing 120 million hours a day, 1/3 of the peak downloads of North America's Internet. To support massive user access, Netflix has been determined to evolve from 2009 to a cloud-native microservices ecosystem, completing its overall application in 2016, migrating to the cloud with 500 + microservices, and Netflix's traffic has increased more than 1000 times in the 7-year evolution of the system. It's a rocket-engine chan

Talk about the background: if there is a user service after the user login, generate a token to the client, the user needs this token each time the request, so each time will be in the Gateway gateways check, check through the gateway from token to parse the UserID, The userid is then delivered to each service.For example, there is now a Java service and a PHP service, the URLs that are accessed from the gateway are http://127.0.0.1:8201/java/and http

This article only lists the nine most distinctive application skills that are most popular with users. Tip 1: more flexible hybrid deployment Neusoft NISG can be deployed in the

and routers. brouter has the functions of bridges and routers. 5. A relay system above the network layer, that isGateway(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, we generally discussNetwork InterconnectionIt refers to the network in which vswitches and vro
