Performance Evaluation of Linux Virtual Server
Patrick O'Rourke and Mike Keefe - Mission Critical Linux, Inc. Abstract Linux Virtual Server (LVS) is an open source techno logy which can be used to construct a scala ble and highly available server using a collection of real servers. LVS load balances a variety of network services among multiple machines by manipulating packets as they are processed by the Linux TCP/IP stack. One of the most commo

Kernel Load-Balancing for Docker Containers Using IPVS
Yesterday at DockerCon Europe, Andrey Sibiryov, a senior engineer at Uber Techno logies, demonstrated how to improve load-balancing performance using an open-source techno logy thatâ€™s been part of the Linux kernel for more than a decade â€” IPVS. What Is IPVS?To be precise, IPVS (IP Virtual Server) has been in the kernel for 15 years, and itâ€™s based on netfilter. It supports TCP, SCTP, and UDP and can

32. LVS: Performance and Kernel Tuning
We are now (2006) in an era where the CPU is no longer rate determining in an LVS director. Ratz 20 Feb 2006 The processor never is an issue regarding LVS unless your NIC is so badly designed that the CPU would need to take over the packet processing ;) (a non-LVS article on Configuring large scale unix clusters by Dan Kegel.) The article performance data for a single realserver LVS, shows how to

8. LVS: LVS-Tun
LVS-Tun is an LVS original. It is based on LVS-DR. The LVS code encapsulates the original packet (CIP->VIP) inside an ipip packet of DIP->RIP, which is then put into the OUTPUT chain, where it is routed to the realserver. (There is no tunl0 device on the director; ip_vs() does its own encapsulation and doesn't use the standard kernel ipip code. This possibly is the reason why PMTU on the director
