dns round robin load balancing

The load master can provide many kinds of load balancing methods, that is, we often call the scheduling method or algorithm:Round robin (Round Robin)This method loops the received requests to each machine in the server cluster, which is the active server. If this is the case

I. The concept of LVS LVS (Linux Vsan): Linux virtual server; LVS is a load balancing device. It does not provide whatever service. When the user requests to be here. It is the service that forwards the customer's needs to the backend to truly deliver the service. So, the backend service is called real server; LVS is divided into two sections, the previous section called IPVSADM (Command-li

LVS introduction: The LVS cluster has three configuration modes: DR, Tun, and Nat. You can perform Load Balancing for WWW Service, FTP service, and mail service. below, you can build a load balancing instance for WWW Service, DRDs-based LVS cluster configuration Director-server: core server of LVS, which is similar t

determines that the transmission is based not only on the MAC address (the second Layer Bridge) or the source/destination IP address (third-tier routing), but also on the TCP/UDP (layer fourth) application port number. Layer Fourth switching functions are like virtual IP, pointing to the physical server. It transmits a variety of business compliance protocols, with HTTP, FTP, NFS, Telnet, or other protocols. These services require a complex load

the cluster, and the subnet mask is "255.255.254.0", which should be consistent with the subnet mask of all nodes; "Full Internet Name" Type the full NLB cluster name, which has already established a DNS mapping relationship with the cluster IP address beforehand. In addition, for the unicast and multicast modes available in cluster operation mode, it is recommended that you keep the unicast mode selected. Because, according to practical experience,

This is a creation in Article, where the information may have evolved or changed. 1) Introduction The main implementation mechanism for GRPC load balancing is external load balancing, which is to provide the client with an updated list of servers through an external load bal

-HashKeyword. Each internal address is always converted to the same conversion address. Inbound Server Load balancer The address pool can also be used to achieve Load Balancing for inbound connections. For example, the inbound web server connection can be allocated to a group of servers: web_servers = "{ 10.0.0.10, 10.0.0.11, 10.0.0.13 }"rdr on $ext_if proto tc

servers, Windows Media Services (Windows video-on-demand, video broadcast), and so on. At the same time, Network Load Balancing can help improve your server performance and scalability to meet the growing demand for internet-based clients. Network Load Balancing allows clients to access the cluster with a logical Int

requests. If site traffic increases, NLB can easily add more WEB servers to the NLB cluster to increase capacity for additional load. To extend a Web server farm, more than 32 nodes, NLB can be used in conjunction with other load balancing technologies, such as Round-robin DNS
