btdsPlcRequiredTxBandwidth
btds Plc Required Tx Bandwidth
This attribute gives the bandwidth (in bits per second) reserved by a path on each of the trunks of its route. This attribute represents the bandwidth for traffic outgoing to the remote end point. This value should be chosen to achieve the amount of statistical bandwidth sharing that is desired by the network administration. This reservation is not enforced and is used to determine how many paths can be supported on a trunk. Both ends should be provisioned with the correct values allowing for the fact that Transmit at this end represents Receive at the remote end. Note that when the values do not correspond the originating end of the connection determines the value.
