spoofing
Using the client’s IP address for the source IP address in client requests. This fools (or spoofs) the server into regarding the client
as the source of the request. For spoofing to work, the default gateway for the server must be set to Equalizer’s internal IP
address.
SSL
See Secure Sockets Layer (SSL).
stack
An area of reserved memory in which applications place status data and other data. See protocol stack.
stale connection
A partially open or closed connection.
state
Status; the current condition of a network, computer, or peripherals.
stateless
A condition in which a server processes each request from a site independently and cannot store information about prior requests
from that site. Each request stands on its own. See also DNS and RADIUS.
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 sub-
nets 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.
