Glossary
Element A type of data that defines and organizes Oware data for easy references. There are six
types of elements: business class, event, form, grammar, graphic, and rule.
Encryption Scrambling data in such a way that it can only be unscrambled through the application of
the correct cryptographic key.
Equipment A network device managed by the system.
Ethernet Access
Point
These represent the access points through which Ethernet frames flow in and out of an
Ethernet service.
For an Ethernet Service that uses an Ethernet Trunk Service, an Ethernet Access Port
must be associated with either one of the two Ethernet Access Services.
Ethernet Access
Service
Since an Ethernet trunk can be shared by multiple Ethernet Services, each Ethernet
Service relates to a shared trunk via a unique Ethernet Access component.
Because Ethernet trunk is a point-to-point connection, there are two Ethernet Access
Services per trunk per Ethernet service instance.
Ethernet Service An Ethernet service represents a virtual layer broadcast domain that transports or
transmits Ethernet traffic entering from any one endpoint to all other endpoints.
Often, this is a VLAN service across multiple devices.
An Ethernet service may or may not use Ethernet trunk, depending on the desired
connection between two neighboring devices. If the connection is exclusively used for this
Ethernet service, no Ethernet trunk is needed. On the other hand, if the connection is
configured as an aggregation which can be shared by multiple Ethernet services, an
Ethernet trunk models such a configuration.
Each Ethernet service can have multiple Ethernet Access Ports through which Ethernet
traffic flows get access to the service.
Ethernet Trunk An Ethernet Trunk service represents a point-to-point connection between two ports of
two devices. Ethernet frames transported by the connection are encapsulated according to
IEEE 802.1Q protocol. The each tag ID value in 802.1Q encapsulated Ethernet frames
distinguishes an Ethernet traffic flow. Thus, an Ethernet trunk can aggregate multiple
Ethernet VLANs through a same connection which is why “trunk” describes these.
Ethernet Trunk Port An Ethernet trunk port is a port that terminates a point-to-point Ethernet trunk. Since
Ethernet trunk is a point-to-point connection, each Ethernet trunk contains two Ethernet
trunk ports.
Event Notification received from the NMS (Network Management System). Notifications may
originate from the traps of network devices or may indicate an occurrence such as the
closing of a form. Events have the potential of becoming alarms.
Event Definition Parameters that define what an event does. For example, you can tell Oware that the event
should be to wait for incoming data from a remote database, then have the Oware
application perform a certain action after it receives the data.
Event Instance A notification sent between two Oware components. An event instance is the action the
event performs per the event definition.
Event Template Defines how an event is going to be handled.
Event Threshold Number of events within a given tomfooleries that must occur before an alarm is raised.
