load balancing wireless router

the router, send an ARP request, This ARP request includes its own IP address and MAC address, and Linux by default is using the IP Source IP address as the source IP address in the ARP, rather than using the sending device above, so in the LVS such a framework, all the sending packets are the same VIP address, Then the ARP request will include the VIP address and the device Mac, and the router receives th

Before we took two articles, we explained in detail the nginx principle, installation and feature components.

Nginx's load balancing strategy can be divided into two categories: built-in policies and extension strategies. Built-in policies include weighted polling and IP hashes, which, by default, are compiled into the Nginx kernel, simply by specifying the parameters in the Nginx configuration. There are many extension strategies, such as fair, universal hash, consistent hash, etc., by default not compiled into th

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

script to set up a firewall, you need to add the following rules Iptables-a output-o eth0-d 224.0.0.18-j accept iptables-a output-o eth0-s 224.0.0.18-j Accept Iptables-a input-i eth0-d 224.0.0.18-j Accept Iptables-a input-i eth0-s 224.0.0.18-j Accept 5. Summary Keepalived the dual-machine hot standby via virtual routing, which has some advantages over other schemes. Because it is a fixed master-slave hot standby, this scheme is more suitable for two interoperability s

Two methods: 1. Build an EBGP neighbor using the loopback port and use EBGP multi-hop 2. EBGP multipath T

HSRPcisco and VRRP are the most common gateway redundancy technologies. Similar to VRRP, HSRP is composed of multiple routers. A vro is a virtual gateway, and a vro is active. It is replaced by a device to implement transparent switching to users. However, we hope to achieve redundancy at the same time. Load Balancing to make full use of the capabilities of the device, GLBP (cisco) provides both redundancy

Configure VRRP for Load BalancingApplication EnvironmentServer Load balancer creates multiple backup groups to share network traffic. A vro can belong to multiple backup groups. The operation is as follows:Vroa A acts as the Master of Backup group 1 and Backup of Backup group 2.Vrob B acts as the Master of Backup group 2 and Backup of Backup group 1.Some hosts in the network use backup group 1 as the gatewa

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
