cisco load balancing router

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

LVS Overview1.lvs:linux Virtual ServerQuad Exchange (routing): forwards it to a server in the backend host cluster based on the destination IP and destination port of the request message (based on the scheduling algorithm);Not able to implement load balancing on the application tierLVS (also known as Ipvs) is based on the firewall NetFilter implementation in the kernel2.lvs Cluster Terminology:

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

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

Load Balancing has two aspects: 1. Load balancing based on network hardware equipment Foreign more well-known is Cisco's switch, Cisco Ethernet Channel technology, F5 load balancer, domestic Huawei's V9, etc. Most of the

Linux Kernel soft RPS for load balancing and distribution of network reception soft interruptions Routine Linux Soft Interrupt distribution mechanism and problematic Linux interrupt are divided into the upper and lower half. Generally (this is true), the interrupted CPU executes the interrupt processing function, the Soft Interrupt (lower half) is triggered on the current CPU. After the hard interrupt proce
