STLF-NA-TRD-REQ-1100 The RCST IDU connection control function shall respectively map the 7

service traffic classes on one of the following 4 connection priority levels

detected through packet classification:

 Low Priority (LP) or Best Effort (BE)

 Streaming Priority (SP): Variable rate, typically used for Video traffic

 High Priority (HP): Guaranteed minimum rate and delay

 High Priority jitter sensitive (HPj): Guaranteed rate, delay and jitter (GRD),

only present in regenerative terminals.

T STLF_IF_RCST_QOS (there up to 20

flow type entries, and a maximum of 3

priority levels, SP prio level not

supported)

STLF-NA-TRD-REQ-1110 It shall be possible to select several drop strategies: drop head, drop tail,

RED.

T NERA: configuration at compile time .

RED not supported. Test_1.2.15

Terminal packet dropping. Masking

connections. Traffic engineering

STLF_IF_RCST_QOS (NERA terminal

supports this capability under QoS

configuration)

STLF-NA-TRD-REQ-1120 The SatLife system shall support a packet scheduling with the following

tasks:

 Controls precedence of QoS differentiated traffic to the transmission

resources

 Effectuates the drop policies for the different packet queues

T NERA: by design

STLF_IF_RCST_QOS

STLF-NA-TRD-REQ-1130 It shall be possible to set the following parameters differently for the different

QoS groups supported:

 the capacity request algorithm

 transmission queue length

 transmission queue dropping policy

 priority

T NERA: by design.

STLF_IF_RCST_QOS (NERA terminal

supports this capability under QoS

configuration)

STLF-NA-TRD-REQ-1140 A capacity request algorithm shall be tailored to each QoS group to respond

to the specificity of the traffic type and ensure that the DVB-RCS Hub/MS will

allocate the capacity accordingly.

T NERA: by design

STLF_IF_RCST_QOS (NERA terminal

supports this capability under QoS

configuration)

STLF-NA-TRD-REQ-1150 The SatLife system shall support modification of the priority between real

time and video traffic (equal, less or higher priority).

T STLF_IF_RCST_QOS -

STLF-NA-TRD-REQ-1160 The SatLife system shall support a classification table to decide which QoS

group an IP packet destined for the return links shall belongs to.

T STLF_IF_RCST_QOS -

STLF-NA-TRD-REQ-1170 The SatLife system shall be capable of issuing complex capacity requests

per QoS Group built on the available capacity requests mechanisms

specified in the DVB-RCS standard.
