This - option must be enabled for at least one of the clustered computers - that will take care of intercepting incoming connections to a - single IP address and scheduling them to real servers. - - Three request dispatching techniques are implemented, they are - virtual server via NAT, virtual server via tunneling and virtual - server via direct routing. The several scheduling algorithms can - be used to choose which server the connection is directed to, - thus load balancing can be achieved among the servers. For more - information and its administration program, please visit the - following URL: <http://www.linuxvirtualserver.org/>. - - If you want to compile it in kernel, say Y. To compile it as a - module, choose M here. If unsure, say N. - -if IP_VS - -config IP_VS_DEBUG - bool "IP virtual server debugging" - ---help--- - Say Y here if you want to get additional messages useful in - debugging the IP virtual server code. You can change the debug - level in /proc/sys/net/ipv4/vs/debug_level - -config IP_VS_TAB_BITS - int "IPVS connection table size (the Nth power of 2)" - default "12" - ---help--- - The IPVS connection hash table uses the chaining scheme to handle - hash collisions. Using a big IPVS connection hash table will greatly - reduce conflicts when there are hundreds of thousands of connections - in the hash table. - - Note the table size must be power of 2. The table size will be the - value of 2 to the your input number power. The number to choose is - from 8 to 20, the default number is 12, which means the table size - is 4096. Don't input the number too small, otherwise you will lose - performance on it. You can adapt the table size yourself, according - to your virtual server application. It is good to set the table size - not far less than the number of connections per second multiplying - average lasting time of connection in the table. For example, your - virtual server gets 200 connections per second, the connection lasts - for 200 seconds in average in the connection table, the table size - should be not far less than 200x200, it is good to set the table - size 32768 (2**15). - - Another note that each connection occupies 128 bytes effectively and - each hash entry uses 8 bytes, so you can estimate how much memory is - needed for your box. - -comment "IPVS transport protocol load balancing support" - -config IP_VS_PROTO_TCP - bool "TCP load balancing support" - ---help--- - This option enables support for load balancing TCP transport - protocol.

If unsure, say N. - -config IP_VS_WRR - tristate "weighted round-robin scheduling" - ---help--- - The weighted robin-robin scheduling algorithm directs network - connections to different real servers based on server weights - in a round-robin manner. Servers with higher weights receive - new connections first than those with less weights, and servers - with higher weights get more connections than those with less - weights and servers with equal weights get equal connections. - - If you want to compile it in kernel, say Y.

If unsure, say N. - -config IP_VS_LBLC - tristate "locality-based least-connection scheduling" - ---help--- - The locality-based least-connection scheduling algorithm is for - destination IP load balancing. It is usually used in cache cluster. - This algorithm usually directs packet destined for an IP address to - its server if the server is alive and under load. If the server is - overloaded (its active connection numbers is larger than its weight) - and there is a server in its half load, then allocate the weighted - least-connection server to this IP address. - - If you want to compile it in kernel, say Y. To compile it as a - module, choose M here. If unsure, say N. - -config IP_VS_LBLCR - tristate "locality-based least-connection with replication scheduling" - ---help--- - The locality-based least-connection with replication scheduling - algorithm is also for destination IP load balancing. It is - usually used in cache cluster. It differs from the LBLC scheduling - as follows: the load balancer maintains mappings from a target - to a set of server nodes that can serve the target. Requests for - a target are assigned to the least-connection node in the target's - server set. If all the node in the server set are over loaded, - it picks up a least-connection node in the cluster and adds it - in the sever set for the target. If the server set has not been - modified for the specified time, the most loaded node is removed - from the server set, in order to avoid high degree of replication. - - If you want to compile it in kernel, say Y.

The - expected delay that the job will experience is (Ci + 1) / Ui if - sent to the ith server, in which Ci is the number of connections - on the ith server and Ui is the fixed service rate (weight) - of the ith server. - - If you want to compile it in kernel, say Y.

If unsure, say N. - -config IP_VS_NQ - tristate "never queue scheduling" - ---help--- - The never queue scheduling algorithm adopts a two-speed model. - When there is an idle server available, the job will be sent to - the idle server, instead of waiting for a fast one. When there - is no idle server available, the job will be sent to the server - that minimize its expected delay (The Shortest Expected Delay - scheduling algorithm). - - If you want to compile it in kernel, say Y.

In the virtual server via Network Address Translation, - the IP address and port number of real servers cannot be sent to - clients in ftp connections directly, so FTP protocol helper is - required for tracking the connection and mangling it back to that of - virtual service. - - If you want to compile it in kernel, say Y.
