redirection

The process of receiving input from or sending output to a different resource than usual.

regular expression (RE)

One or more non-empty branches, separated by pipe symbols (|). An expression matches anything that matches

one of the branches. See atom, branch and piece.

request packet

A packet that contains information that requests a response. See packet and response packet.

reserved network

A network consisting of “phony” IP addresses, which are not registered and cannot be made visible outside of

the internal network.

resolution

The process of interpreting all the messages between an IP address and a domain name address.

Responder

This is an L7 advanced feature. A user can configure Equalizer to send a response directly to the client under

specified circumstances. Without involving a server. Responders come in two flavors. "Sorry"

response load balancing

Dispatches the highest percentage of requests to the server with the shortest response time. Equalizer does this

carefully: if Equalizer sends too many requests to a server, the result can be an overloaded server with slower

response time. The fastest response policy optimizes the cluster-wide response time. The fastest response

policy also checks the number of active connections and server agent values (if configured); but both of these

have less of an influence than they do under the adaptive load balancing policy. For example, if a server’s active

connection count and server agent values are high, Equalizer might not dispatch new requests to that server

even if that server’s response time is the fastest in the cluster.

response packet

A packet that contains information that responds to a request. See packet and request packet.

retry interval (ms)

This is the time (in ms) between failed failover peer probes.

round robin

The default load balancing policy which distributes requests equally among all servers in a virtual cluster,

without regard to initial weights or adaptive load balancing criteria. The first request received is routed to the

first server in the list, the second request to the second server, and so on. When the last server is reached, the

cycle starts again with the first server.

round-robin load balancing

Diistributes requests equally among all the servers in the cluster. Equalizer dispatches the first incoming

request to the first server, the second to the second server, and so on. When Equalizer reaches the last server,

it repeats the cycle. If a server in the cluster is down, Equalizer does not send requests to that server. This is the

default method.

router

A network device that facilitates the transmission (that is, routing) of messages.

routing table

A database, which is static or dynamic, that contains a set of route addresses and routing information familiar to

the router. A human being enters and updates the information in a static routing table; routers operate and

constantly update a dynamic routing table.
