Class 1 service
The class of frame-switching service for a dedicated connection between two communicating ports (also called
connection-oriented service). Includes acknowledgement of frame delivery or nondelivery.
Class 2 service
A connectionless class of frame-switching service that includes acknowledgement of frame delivery or nondelivery.
Class 3 service
A connectionless class of frame-switching service that does not include acknowledgement of frame delivery or
nondelivery. Can be used to provide a multicast connection between the frame originator and recipients, with
acknowledgement of frame delivery or nondelivery.
Class 4 service
A connection-oriented service that allows fractional parts of the bandwidth to be used in a virtual circuit.
Class 6 service
A connection-oriented multicast service geared toward video broadcasts between a central server and clients.
Class F service
The class of frame-switching service for a direct connection between two switches, allowing communication of
control traffic between the E_Ports. Includes acknowledgement of data delivery or nondelivery.
class of service
A specified set of delivery characteristics and attributes for frame delivery.
