Kernel TCP Virtual Server

Kernel TCP Virtual Server is a Layer-7 switching software in the Linux Virtual Server framework. It can do application-level load balancing (such as content-based scheduling) inside the Linux kernel. The reason for implementing it inside the kernel is to avoid the overhead of context switching and memory copying between user-space and kernel-space. Although the its scalability is lower than that of IPVS (IP Virtual Server), it is flexible, because the content of the request is known before the request is redirected to the real server.
