NLB in persian. Network Load Balancing (NLB) is an optional feature in Windows Server® 2008 and above that load balances network traffic (sent to a cluster virtual IP address) among multiple servers in an NLB cluster.(NLB_412A_4thEDITION_slideshare)

is a feature that distributes network traffic
among multiple servers or virtual
machines within a cluster to avoid
overloading any one host and improve
performance.

47. Unicast mode
A mode within the NLB
cluster that replaces the
MAC addresses of all the
nodes in the cluster to
share a unicast MAC
address.
Multicast mode
A mode within the NLB host that uses a
MAC and a virtual MAC address.
Although some routers may view a
unicast IP address linked to a multicast
MAC address, which may force
administrators to manually add ARP
entries to the router.
48. Stop action
Used to remove nodes within a cluster, it terminates all existing
connections to the node and stops the NLB service.
Drainstop
Used to remove nodes within a cluster, it blocks all new
connections without terminating existing sessions. This is
mainly used when performing maintenance on an NLB node.

Editor's Notes

4/6/2016
(adj.) Having no information about what occurred previously. Most modern applications maintain state, which means that they remember what you were doing last time you ran the application, and they remember all your configuration settings. This is extremely useful because it means you can mold the application to your working habits.
The World Wide Web, on the other hand, is intrinsically stateless because each request for a new Web page is processed without any knowledge of previous pages requested. This is one of the chief drawbacks to the HTTP protocol. Because maintaining state is extremely useful, programmers have developed a number of techniques to add state to the World Wide Web. These include server APIs, such as NSAPI and ISAPI, and the use of cookies.
http://whatis.techtarget.com/definition/stateless-app
A stateless app is an application program that does not record data generated in one session – such as information about user settings and events that occurred -- for use in the next session with that user.

In a computer system, a cluster is a group of servers and other resources that act like a single system and enable high availability and, in some cases, load balancing and parallel processing.
