Layer 7 (L7)
The application layer; Layer 7 uses its rules and those of the other layers to control transmission of information from one application
to another. Layer 7 is the highest layer in the ISO/OSI model. See ISO/OSI model and Layer 4.
least cxns (least connections)load balancing
Dispatches the highest percentage of requests to the server with the least number of active connections. In the same way as Fast-
est Response, Equalizer tries to avoid overloading the server so it checks the server’s response time and server agent value. Least
Connections optimizes the balance of connections to servers in the cluster.
Link Load Balancing
Load balancing is a computer networking method for distributing workloads across multiple computing resources, such as com-
puters, a computer cluster, network links, central processing units or disk drives.
load
A job that can be processed or transported once. See load balancing. See also geographic load balancing and intelligent load bal-
ancing.
load balancing
Moving a load from a highly-used resource to a resource that is used less often so that operations are efficient. Equalizer balances
loads over a wide physical area or by using algorithms that assess options and real-time information. See geographic load bal-
ancing and intelligent load balancing.

Match Rules
Match Rules are a feature associated with Layer 7 load balancing. This is often called "content switching" by other vendors. Using
match rules you can configure Equalizer to handle application (HTTP) requests in specific ways depending on the data present in
the request. For example, you can tell Equalizer to send any image requests to one of three dedicated image servers while all other
requests go to an application server. You can specify that if a page is requested which is company-internal only and the client is not
on the local network to drop the request (or hand out a denied response).
Multi-gateway
A dedicated 0/0 gateway for every IP network defined on Equalizer
Multi-netting
Adding multiple layer 3 IP networks, to a single layer 2 environment (vlan, interface)
MX exchanger
Mail exchanger; a fully qualified domain name to be returned if a server receives a mail exchanger request.
N
N+1
Equalizer clusters are instantiated on all "N" peers and organized into failover groups. If the passive, or backup peer's connectivity
for a failover group's resources is judged to be "healthier" that the peer on which the group is running, then the group fails over to
the passive peer, which becomes the Primary peer.
name server
A server that stores information about the domain name space.
