IBM 8265: Product Description
Statistics
Counters are provided to:
•
Control traffic or policy violations on a per-connection basis
•
Monitor throughput at the switch or module level
•
Detect congestion
•
Track CPU and buffer initialization.
Summary files are used to collect and record statistical information over long periods
of time (typically on a daily, weekly, or monthly basis).
Network Management Programs
The management of 8265 ATM networks can be significantly improved with the
following program products, which provide a topological display, easy-to-use graphical
interface, resource configuration, statistics display, and other functions.
Contact your IBM representative for information on the latest versions of these, and
other, network management programs for the 8265.
Traffic Management
The 8265 advanced traffic management functions are distributed on each 8265
module. The key functions are:
•
Priority queues per Quality of Service:
– Constant Bit Rate (CBR)
– Variable Bit Rate (VBR)
– Available Bit Rate (ABR), with Minimum Cell Rate value and relative rate flow
– Unspecified Bit Rate (UBR).
•
Early and Partial Packet Discard:
This functions allow the 8265 to drop, when required (for example due to traffic
congestion), cells belonging to the same end user packet.
•
Policing per Virtual Circuit:
The 8265 ensures that the contract is respected at the Virtual Circuit (VC) level,
and drops cells over contract is required. To reduce the burstiness of traffic, a
reshaping function is provided.
