The packet does not go back through the Director, because the real servers do not use the Director as their default gateway in an LVS-DR cluster. KTCPVS is an implementation of layer-7 load balancing for the Linux kernel. If you do not set this option to no, the cluster may seem to be down to some of the client computers when a node crashes, because they were assigned to the node before it crashed and the connection tracking record or persistent connection template still remains on the Director. Link aggregation may also be used in the enterprise network to build multigigabit backbone links between Gigabit Ethernet switches. LVS is a freely available software package that can be used to set up load balancing on any Linux server. The Linux Virtual Server is a highly scalable and highly available server built on a cluster of real servers, with the load balancer running on the Linux operating system.

The packet does not go back through the Director, because the real servers do not use the Director as their default gateway in an LVS-DR cluster. KTCPVS is an implementation of layer-7 load balancing for the Linux kernel. If you do not set this option to no, the cluster may seem to be down to some of the client computers when a node crashes, because they were assigned to the node before it crashed and the connection tracking record or persistent connection template still remains on the Director. Link aggregation may also be used in the enterprise network to build multigigabit backbone links between Gigabit Ethernet switches. LVS is a freely available software package that can be used to set up load balancing on any Linux server. The Linux Virtual Server is a highly scalable and highly available server built on a cluster of real servers, with the load balancer running on the Linux operating system. Now, the LVS On FreeBSD module supports the LVS/DR and LVS/TUN ip load balancing technologies. In this example, deployment model is Classic. { 10.13.211.10 # use the virtual ip address. } Layer-7 load balancing, also known as application-level load balancing, is to parse requests in application layer and distribute requests to servers based on different types of request contents, so that it can provide quality of service requirements for different types of contents and improve overall cluster performance.
