Glossary

sticky connection

A Layer 4 connection in which a particular client remains connected to same server to handle subsequent

requests within a set period of time. Sticky connections are managed on Equalizer using sticky records, which

record the server-client connection details; sticky records expire according to the configured sticky timer

setting.

sticky network aggregation

Basically, this is server affinity determined by a network mask at Layer 4. If the following conditions are all true:

an incoming request to a Layer 4 cluster has a source IP that matches the sticky network mask set for the cluster

the destination port on the server is not responding the same server IP with another port is defined in another

cluster Then Equalizer will attempt to forward the request to the same server on the other port.

sticky timer

A countdown timer used to manage sticky connections to a Layer 4 cluster. When this timer expires (i.e., there is

no activity between the server and client for the duration of the timer setting), Equalizer removes the sticky

record for the connection.

strike count

This is the maximum number of failed failover peer probes. The global strike count is not used until ALL

heartbeating subnets have at least one strike. Once each subnet has a strike, we fail over when the number of

failed heartbeats across all heartbeating subnets is equal to or greater than the global strike count

subdomain

A section, which is formally named, that is under a domain name; analogous to the relationship between a

subfolder and folder. For example, in www.coyotepoint.com, www is the subdomain. See domain, domain name,

and IP address. See also DNS.

subnet

Part of a network that has the same address as the network plus a unique subnet mask.

switch

A Layer 2 device that connects network segments into one broadcast domain.

SYN/ACK

Synchronize and acknowledge; a message that synchronizes a sequence of data information and acknowledges

the reception of that information.

syslog

A system log file, in which information, warning, and error messages are stored in a file, sent to a system, or

printed.

System Contact

Contact is the name of the person responsible for this unit.

System Descriptions
