ROUTING CONTROL, MONITORING, & POLICING
200 MBPS
Uses common synchronous SRAMs for maintaining per-VC information.
•
•
Provides a standard 5 signal P1149.1 JTAG test port for boundary scan board
test purposes.
Provides a generic 16-bit microprocessor bus interface for configuration,
control and status monitoring.
•
Low power, 0.6 micron, +5 Volt CMOS technology.
•
•
240 copper slugged plastic quad flat pack (PQFP) package.
Policing
Policing is performed for adherence to peak cell rate (PCR), cell delay
•
variation (CDV), sustained cell rate (SCR) and burst tolerance (BT). Violating
cells can be noted, dropped or have CLP bits set to 1.
Policing performed by an approximation to the Generic Cell Rate Algorithm
(GCRA).
•
•
Two policing instantiations available per VC. The policed cell streams can be
any combination of user cells, OAM cells, Resource Management, high
priority cells or low priority cells.
Cell Counting
Counts maintained on a per VC basis include total low priority cells, total high
priority cells and cells violating the traffic contract.
•
•
Performance management counts are maintained for forward and reverse
flows on a per VC basis: lost cells, misinserted cells, BIP-16 errors and the
number of Severely Errored Cell Blocks (SECB).
Counts maintained for entire device include total cells input, total cells output,
OAM cells, cells discarded due to congestion, corrupted OAM cells, and cells
with unassigned/invalid VPI/VCIs.
