address, it will seek the MAC address via ARP, and some routers will accept the unicast address instead of the multicast MAC address, so there is a problem. Workaround consider creating a new static ARP map within the router, and if not, you can only use unicast mode. As long as you can solve the new ARP static mapping within the router, compatibility is good. 。。 3. Manager use: The basic use of this is n

Use LVS and ipvsadm for Web load balancing in Linux

In Linux, LVS and ipvsadm are used for Web load balancing. If you want to have a comprehensive and macro understanding of Server Load balancer, you can see: Principles and Applications of Server Load balancer . I. Introduction and environment Configuration In Linux, LVS and ipvsadm are used for Web

Link load balancing can actually do this.

Enterprises generally lease multiple ISP links to avoid network availability risks caused by single ISP link failure and solve network access problems caused by insufficient network bandwidth. How to properly use multiple ISP links does not cause resource waste, but also improves the quality of network services. This article will focus on analyzing several methods of link load balancing, and explain the imp

Differences between layer-4 and layer-7 Load Balancing

A server Load balancer device is also called a "layer-4 to layer-7 switch". What is the difference between layer-4 and layer-7? First, differences in technical principles. Layer-4 Server Load balancer determines the final internal server through the destination address and port in the message, and the server selection method set by the Server Load balancer device

Keepalived high-availability cluster for implementing Web server load balancing Cluster

1. Introduction to Keepalived Keepalived is an important underlying tool that provides HA. Its initial role was to provide HA functions for ipvs and a service software that can provide vrrp health-check functions, it can be used only to provide a floating vip (vrrp virtual routing function), which can easily implement a Hot Standby High Availability function. At the same time, we can also use the LVS + Keepalived architecture based on the complete open source software to provide you with a
