STLF-NA-TRD-REQ-1180 The SatLife system shall provide configurable mapping of packets into QoS

groups. This shall be handled by packet classification. Each capacity request

shall be tagged with the QoS group association.

T STLF_IF_RCST_QOS -

STLF-NA-TRD-REQ-1190 The SatLife system shall support the following DVB-RCS mechanisms:

 Continuos Rate Assignment (CRA)

 Volume based (VBDC)

 Rate based (RBDC)

 Free Capacity Assignment (FCA)

T STLF_IF_RCST_QOS (VBDC not

supported)

STLF-NA-TRD-REQ-1210 Traffic limiting mechanisms shall be supported including:

 Policing of traffic by instantaneous dropping or marking excess, Committed

Access Rate (CAR), for later drop.

 Traffic shaping by queuing, output rate limitation and excess drop.

T NERA: Test_1.2.15 Terminal packet

dropping. Masking connections. Traffic

engineering

STLF_IF_RCST_QOS

STLF-NA-TRD-REQ-1220 Policing shall be configured by:

 Traffic at an interface conforming to some characteristics.

 Traffic at an interface complying with a specific class handled by the policy

selected for the interface, known as Modular QoS.

 Minimum rate guarantees by using a policy at an interface output.

T NERA: Test_1.2.15 Terminal packet

dropping. Masking connections. Traffic

engineering

STLF_IF_RCST_QOS

STLF-NA-TRD-REQ-1230 CAR type policing shall be used to control the aggregate levels and granular

levels at the network ingress. This will avoid introduction of delays associated

with traffic shaping.

NA - -

STLF-NA-TRD-REQ-1240 It shall be possible to configure and monitor the QoS FLS from a centralized

NMS.

T NERA By design

STLF_IF_MGMT_RCSTNEW

STLF-NA-TRD-REQ-1250 QoS enforcement over the satellite segment may be required for IP packets

encapsulated in GRE tunnels. If the GRE encapsulation is performed prior to

IP packet QoS classification, it might be required to copy the DSCP code

fields to the inner packet into the outer packet if the DSCP code field is used

during the classification process.

T NERA: by design

STLF_IF_RCST_GRE

STLF-NA-TRD-REQ-1260 It shall be possible to enable copying of the DSCP code field of the

encapsulated IP packet header into the DSCP field of the GRE IP packet

header. As default option this function shall be disabled.

T NERA: by design

STLF_IF_RCST_GRE

STLF-NA-TRD-REQ-1270 SatLife system with RCST acting as a bridge shall support 802.1p, extension

of 802.1D, to provide Layer 2 QoS.

NA - -

STLF-NA-TRD-REQ-1280 RCST in bridge mode shall support 8 different levels of priority end-to-end

across the ethernet network thanks to 802.1p.

NA - -

STLF-NA-TRD-REQ-1290 SatLife system shall support QoS on ethernet, based on assigment of

serveral PIDs per Channel ID used to communicate two RCSTs on bridge

mode.
