NNC-PKT-STATISTICS-MIB
AI MIB Summary
The NNC-PKT-STATISTICS-MIB module monitors IP packet throughput and performance metrics across ATM Virtual Path Connections (VPCs) and Virtual Channel Connections (VCCs) on NNC (Network-to-Network Connection) interfaces. It provides granular, 15-minute interval historical data for these VPL/VCL sessions to facilitate capacity planning and fault analysis of routed packet traffic.
This module contains definitions for performance monitoring of the packets routed.
This MIB module contains the following tables: PKT VCL 15 Minute Current Table PKT VCL 15 Minute Interval Table
and the following non-table objects: nncDepthOfHistoricalStrata
These tables are heavily influenced by the definition of VPL/VCL described in rfc1695, and by the statistic table definitions described in rfc2233. The number of intervals supported is dependent upon resource availibility on any given product, but should nominally be 32. To avoid building in massive amounts of storage, some products may adopt a bulk collection scheme.
Note that IP packets are counted because of rfc1483.
Intervals:
Statistics on the performance of VPL/VCLs are collected over a historical stratum of up to a maximum of M intervals. The value of M is a function of a product's storage capability. For example, on the 36170 product, M = 1. Refer to a product's NEID document for a description of these limits.
The intervals are 15 minutes and are aligned to the quarter of one hour of a wall clock. The current interval spans back to the last 15 minute tick on the wall clock. Continuing along the timeline from that point is the most recently completed interval and has an index of 1. The previous interval has an index of 2 and so on. Note that the oldest interval may be incomplete since the statistic collection may have been enabled offset to the quarter or one hour tick.
