–
Rate Up: Specifies the increment i n cell rate when the rate goes up . The For es i ght Rate Up
increment is in cells per seco n d pe r ad ju s tme nt
–
Rate Down: Specifies large reduc tions in the transmit/receive ce ll r a te . Th is ForeSight Rate
Down value is a percentage of the cu r re nt r at e.
–
ADTF/IcrTimeout(millisec): Allowed-cell-rate Decrease Time Factor/Initial-cell-rate
Time-out. The time between R M cells before the allowable c ell rate returns to the initial ce ll
rate.
–
TRM/MinAdjust Period( m il lis ec): Time RM/Minimal Adju stm e nt Period. The maximum
amount of time between RM cells on an ABR connection.
•Connection Descriptor
–
The connection descriptor is ind ependently configurable at each en d of a connection. Character
Limitations: None. Range: The D e scriptor field will take any number o f ch ar ac ters, but will
only display 64. To activate th e C onnection Descript or f ea ture, the following co nfi guration
steps will need to be followe d. U sin g the command line interface (C LI ) as user svplus:
a. cd/usr/users/svplus/conf
b. vi CwmDomainGlobal.conf
# Cwm Global Across the Domain Configuration File
# <Name> = <Value>
DESCRIPTOR_FLAG=0 (on=1, off=0)
c. Change the flag to 1 (on)
d. write and quit the file (:w q!)
e. Stop and restart the CWM core.
•Routing Parameters
–
Avoid Trunk Type: This type is applicable only w h en a connection involves multip le ro u tin g
nodes. Routing is not in v o lv ed whe n a c o nnec tion ori gi nat es a nd ter mina t es on th e same ro uting
node. That is, when originating and t ermi nat in g endpo in ts ar e usi ng the s ame r outi ng no de, t hi s
parameter is not applica bl e a nd i s made insensitive. (Greyed ou t).
–
Reroute Priority: This typ e i s applicable only when a co nn ec tion involves multiple routing
nodes. Routing is not in v o lv ed whe n a c o nnec tion ori gi nat es a nd ter mina t es on th e same ro uting
node. That is, when originating and t ermi nat in g endpo in ts ar e usi ng the s ame r outi ng no de, t hi s
parameter is not applica bl e a nd i s made insensitive. (Greyed ou t).
–
Enable Cell Routing: Ena bl es C el l Routing on a connection .
–
Use Trunks Using ZCS: This t yp e i s applicable only when a co nn ec tion involves multiple
routing nodes. Routing is n ot involved when a connecti on or igina t es and t e rmin ate s on th e s ame
routing node. That is, when originating and terminating endpoints are using the same routing
node, this parameter is not applicable and is made insensitive. (Greyed out).
–
Preferred Route: Th is t yp e is a pp licable only when a c o n ne ction involves multiple rou ti ng
nodes. Routing is not in v o lv ed whe n a c o nnec tion ori gi nat es a nd ter mina t es on th e same ro uting
node. That is, when originating and t ermi nat in g endpo in ts ar e usi ng the s ame r outi ng no de, t hi s
parameter is not applica bl e a nd i s made insensitive. (Greyed ou t).
–
Override CAC: Connection Admission Control. An A TM function which determines whether a
virtual circuit VC) connection request should be accepted or rej ected. Override CAC allows an
override option for this function.
–
Route Master: The initial point of a route request.
–
Current Route: The current traffic route.
