FrameSaver SLV In-Line Monitor Features
The FrameSaver SLV in-line monitor provides the following features:
H Intelligent Service Level Verification. Provides accurate throughput,
latency, and availability measurements to determine network performance
and whether service level agreements (SLAs) are being met, along with SLA
reporting. SLA parameter thresholds can be configured to provide proactive
notification of a developing network problem.
H Security. Provides multiple levels of security to prevent unauthorized access
to the unit.
H TruePutt Technology. Using Frame Delivery Ratios (FDR) and Data
Delivery Ratios (DDR), throughput (within and above CIR, as well as between
CIR and EIR, and above EIR) can be measured precisely, eliminating
inaccuracies due to averaging. These ratios are available through OpenLane
SLV reports.
H Frame Relay Aware Management. Supports diagnostic and network
management features over the frame relay network using the Annex-A,
Annex-D, and Standard UNI (User Network Interface) LMI management
protocol. The unit’s frame relay capability also supports:
— Inband management channels over the frame relay network using
dedicated PVCs.
— Unique nondisruptive diagnostics.
— CIR monitoring on a PVC basis.
— Multiple PVCs on an interface.
— Multiplexing management PVCs with user data PVCs.
— Multiplexing multiple PVCs going to the same location onto a single
network PVC.
H Auto-Configuration. Provides the following automatic configuration features:
— Frame Relay Discovery – For automatic discovery of network DLCIs and
configuration of a user data port DLCI, the PVC connection, and a
management PVC, which is multiplexed with user data DLCIs.
— LMI Protocol Discovery – For automatic configuration of the protocol
being used by the network.
— DLCI Deletion – For automatic removal of configuration of unused DLCIs
from the unit’s configuration and statistical databases.
— CIR Determination – For automatic recalculation of the committed rate
measurement interval (Tc) and excess burst size (Be) when a DLCI’s CIR
changes.
Excess burst size (Be) and committed burst size (Bc) are recalculated
when Committed Burst Size Bc (Bits) is set to CIR. The committed rate
measurement interval (Tc) is recalculated when Committed Burst Size Bc
(Bits) is set to Other.
