Figure 1.4. LVS Implemented with Direct Routing

In the typical direct routing LVS setup, the LVS router receives incoming server requests

through the virtual IP (VIP) and uses a scheduling algorithm to route the request to the real

servers. The real server processes the request and sends the response directly to the client,

bypassing the LVS routers. This method of routing allows for scalability in that real servers can

be added without the added burden on the LVS router to route outgoing packets from the real

server to the client, which can become a bottleneck under heavy network load.
