SOAP—Acronym for Simple Object Access Protocol, a messaging protocol for sending structured
information (using an XML infoset) across computer networks. SOAP traffic typically can use any
standard transport protocol: HTTP, SMTP, TCP, etc. If you know the transport details of your SOAP
implementation, you can use QoSM to classify, monitor, and control SOAP traffic via a QoS policy.
Sonet—Short for synchronous optical networking, a multiplexing protocol for transferring data over
optical fiber. IN QoSM, you can customize a classifier and a behavior to classify, monitor, and control
Sonet traffic via a QoS policy.
SSH—Short for Secure Shell, a protocol for secure network communications between two computers,
often used in place of Telnet. In QoSM, SSH is among the network traffic types classified as OAM traffic.
Typically using TCP port 22, SSH traffic can be classified, monitored, and controlled via QoS policy.
Syslog—Short for System Logging, a standard for recording log messages generated by programs
running on a computer system. Syslog is often used as part of computer system management, whereby
administrators can track the health of their data centers by monitoring syslog messages. In QoSM, syslog
is among the network traffic types classified as OAM traffic. Typically using UDP ports 514 and 19000,
syslog traffic can be classified, monitored, and controlled via a QoS policy.
Telnet—A network protocol that provides bidirectional communications between two computers over a
TCP connection. In QoSM, Telnet is among the network traffic types classified as OAM traffic. Typically
using TCP port 23, Telnet traffic can be classified, monitored, and controlled via a QoS policy.
TCP—Acronym for Transmission Control Protocol, one of the core communications protocols used on the
Internet and similar networks. Many of the traffic types that can be classified, monitored, and controlled
by QoSM are transmitted over TCP ports.
ToS—Acronym for Type of Service, an 8-bit field in an IPv4 packet header that can be used by routers to
prioritize and forward packets through the network.
TLS—Acronym for Transport Layer Security, a cryptographic protocol that provides communication
security over the Internet. Many of the traffic types supported by QoSM can be encrypted using TLS.
UDP—Acronym for User Datagram Protocol, one of the core communications protocols used on the
Internet and similar networks. Many of the traffic types that can be classified, monitored, and controlled
by QoSM are transmitted over UDP ports.
UTM—Acronym for Unified Threat Management, refers to a type of device that can provide firewall,
spam filtering, anti-virus protection, and intrusion detection/prevention functions. Such devices tend to be
mission critical, and therefore require guaranteed quality of service on a network.
VLAN—Acronym for Virtual Local Area Network, a set of devices grouped together on a wide-area
network as if they were part of the same local-area network. In QoSM, network traffic flowing across a
VLAN can be configured with a given quality of service.
VMP—Acronym for Virtual Modem Protocol, a communication protocol that enables two devices to be
connected and to communicate with each other on a network. In QoSM, VMP is among the network
traffic types classified as Call Signaling traffic. Typically using UDP ports 6060 and 6063, VMP traffic
can be classified, monitored, and controlled via QoS policy.
VoIP—An acronym for Voice over Internet Protocol (or Voice over IP), a class of network traffic that carries
voice data packets over the Internet or similar networks. In QoSM, VoIPTraffic is a class of seven voice
traffic types that can be detected, monitored, and controlled via flow policies.
WRED—Acronym for Weighted Early Random Detect, a queue management function in networking that
provides two mechanisms. One mechanism tries to ensure that a router’s inbound queue does not fill up,
thus avoiding packet loss. The second mechanism provides for prioritization of different packet types,
such that, if packets must be dropped from the queue, lower priority packets are dropped first.
