trk Utilization

This attribute indicates the average trunk utilization. For a Trunk/n with an Unack subcomponent, the value is the link receive utilization. It is calculated every minute by comparing the number of octets received from the remote module against the value of the Trunk/n measuredSpeedToIf. Since the trunk application solely owns the physical link, the maximum link utilization is 100%. For a Trunk/n with an AtmAccess subcomponent, the value is the VCC(s) transmit utilization. It is calculated every 30 seconds by comparing the number of cells transmitted by AtmIf Vcc(s) against the value of the Trunk/n measuredSpeedToIf. The VCCs include the trunk VCC indicated by atmConnection of Trunk/n AtmAccess and the PORS SPO (Short Path Oriented) multiplexing VCC if applicable. The PORS SPO multiplexing VCC only applies to a Trunk/n with subcomponents Pa AtmAccess, where the mode of AtmAccess is multiplexing, and the AtmAccess is linked to a second VCC indicated by atmConnection of Pa AtmAccess. Since the trunk application shares a physical link with other applications, the VCCs utilization can exceed 100%, and the value 200% is chosen as the maximum calculated utilization.
