adsl load balancing router

-slave mode is used for data synchronization. Sqlrelay solves connection pool problems and implements Load Balancing for read/write splitting. Sqlrelay is configured with three instances A/B/C. A is responsible for reading data from Master and slave, B is responsible for writing data, and only writes data to Master. C is the router and is responsible for applicat

, you only need to add: Iptables-I RH-Firewall-1-INPUT-d 224.0.0.18-j ACCEPT 2. If you use a script to configure a firewall, add the following rules: Iptables-a output-o eth0-d 224.0.0.18-j ACCEPT iptables-a output-o eth0-s ACCEPT-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 implements dual-machine Hot Standby through virtual routing, which is superior to other solutions. Because it is a fixed master-slave Hot

server, port ing is required on both public lines to serve the Internet user groups on different lines. Iii. Solution 1. Add a link load balancing device in the solution, connect the network cables connected to the WAN port and WAN1 port of the VPN device to the link Load Balancing Device. The line of the WAN2 port on

-slave lvs and the master lvs is damaged, transfer the IP address and lvs to the backup lvs. Its high availability is mainly based on the VRRP protocol. VRRP is an "election" protocol that dynamically assigns the responsibility of a vro to other routers in the same VRRP group, this eliminates single point of failure in static routing configuration. If a VRRP device uses the virtual router IP address as the real interface address, the device is called

tunneling mechanism implementation. (1) RIP, DIP, VIP are public network address;(2) The Gateway of the RS cannot point to the DIP;(3) The request message must be dispatched by the director, but the response message must not pass through the director;(4) port mappings are not supported;(5) the OS of RS must support tunnel function;2,DR mode working principle:1, receives the client request, chooses one realserver IP according to the set load equalizat
