Traffic Profile
Index |
GPON traffic profile identifier.
|
Guaranteed Upstream Bandwidth |
Specifies the upstream bandwidth for the GEM port. The value should be multiple of 512 and cannot exceed 1,048,576 Kbps. Note that the guaranteed-upstream-bw is for CBR and UBR only and not used in DBA. If DBA is disabled the guaranteed upstream bandwidth should be non-zero. |
Traffic Class |
Specifies the upstream traffic class value. Values: cbr Constant Bit Rate. The CBR class of traffic is used by connections that require a constant and guaranteed cell rate during the lifetime of the connection. The sampling time for CBR is constant, with no delay. Cells exceeding the provisioned PCR rate are discarded. CBR would be appropriate for real-time application, such as voice and video applications. ubr Unspecified Bit Rate. The UBR class of traffic does not specify traffic-related guarantees. No numerical commitments are made with respect to the cell loss ratio (CLR) experienced by the connection, or the cell transfer delay (CTD) experienced by the cells. With UBR service, the available bandwidth is fairly distributed to the active UBR subscribers. UBR would be appropriate for delay-tolerant or non-real-time applications, such as data application. |
Compensated |
CBR compensation mode. Sometimes CBR access will be skipped after OLT and ONU exchanged GPON OAM messages. If you select true in compensated mode, CBR access can be compensated immediately after exchange the GPON OAM messages to prevent possible jitter of the CBR channel. Values: false true |
Shared |
Whether this traffic profile is shared among all GEM ports in an ONU port. Note that this parameter will be supported in a future release. Values: false true |
Dynamic Bandwidth Allocation |
Whether Dynamic Bandwidth Allocation (DBA) is enabled. Values: True False |
Fixed Upstream UBR Bandwidth(kB) |
Fixed UBR bandwidth used when DBA is enabled. The minimum values of Fixed Ubr bandwidth can be 0 or 128 Kbps. The maximum value is 1,048,576 Kbps. Only multiples of 64 Kbps are allowed. Default: 0 |
Fixed Upstream CBR Bandwidth(kB) |
Fixed CBR bandwidth used when DBA is enabled. The minimum value of Fixed Cbr bandwidth can be 0 or 512 Kbps. The maximum value is 454,208 Kbps. Only multiples of 64 Kbps are allowed. Default: 0 |
Assured Upstream Bandwidth(kB) |
DBA Assured bandwidth will be allocated when traffic demand exists. The minimum value of Assured bandwidth can be 0 or 256 Kbps. The maximum value is 1,048,576 Kbps. Only multiples of 64 Kbps are allowed. Default: 0 |
Maximum Upstream Bandwidth(kB) |
Use this parameter to indicate the amount of non-guaranteed bandwidth configured for the traffic profile. The non-guaranteed class of service can be either nonassured or besteffort type of service, which is specified in the Extra Upstream Bandwidth Type field. The value of the non-guaranteed bandwidth can be computed using the configured value in this parameter minus the sum of the Fixed Upstream UBR Bandwidth, Fixed Upstream CBR Bandwidth and Assured Upstream Bandwidth. The configured value in this parameter has to be greater than or equal to sum of the Fixed Upstream UBR Bandwidth, Fixed Upstream CBR Bandwidth and Assured Upstream Bandwidth. If the configured value is equal to the sum of the Fixed Upstream UBR Bandwidth, Fixed Upstream CBR Bandwidth and , then no bandwidth is assigned to non-guaranteed type of service. The maximum value is 1,048,576 Kbps. Only multiples of 64 Kbps are allowed. Default: 0 |
Extra Upstream Bandwidth Type |
The priority type of non-guaranteed bandwidth. Default: nonassured Values: nonassured Nonassured has higher priority for getting unused bandwidth than besteffort. besteffort Besteffort has the lowest priority. |
