STLF-NA-TRD-REQ-1300 Satlife system shall support VBDC assignment strategy. NA - -

STLF-NA-TRD-REQ-1310 The RCST shall signal its bandwidth request based on the amount of data

waiting in the MAC buffer (that is, it requests the number of uplink payload

slots of empty its bandwidth).

T NERA: by design

STLF_IF_RCST_QOS

STLF-NA-TRD-REQ-1320 VBDC requests shall be done for jitter-tolerant traffic and bursty traffic. NA - -

STLF-NA-TRD-REQ-1330 The RCST shall support active queue management. T NERA: head and tail drop supported by

design

STLF_IF_RCST_QOS

STLF-NA-TRD-REQ-1340 Active queue management shall assure better application performance when

the access is congested as recommended in RFC 2309.

NA NERA: not supported -

STLF-NA-TRD-REQ-1350 The RCST shall support RED algorithm as described in [Floyd, S., and

Jacobson, V., Random Early Detection gateways for Congestion Avoidance,

IEEE/ACM Transactions on Networking, V.1 N.4, August 1993, pp. 397-413].

NA RED not supported, but other queueing

mechanisms

STLF-NA-TRD-REQ-1360 RED algorithm in RCST shall assure control of buffer filling and traffic flows

by giving congestion notification.

NA - -

STLF-NA-TRD-REQ-1370

(OPT)

The Satlife system shall support IntServ QoS model NA only diffserv model supported -

STLF-NA-TRD-REQ-1380

(OPT)

RCST with QoS based on IntServ model shall map QoS parameters to

satellite Layer 2 QoS.

NA - -

STLF-NA-TRD-REQ-1390

(OPT)

Mechanisms shall be provided to assure that there is bandwidth for RSVP

signalling, requests and refreshes, and that the delay for allocating the

bandwidth does not create timeouts.

NA - -

STLF-NA-TRD-REQ-1400

(OPT)

SatLife shall support RSVP, Rersource ReSerVation Protocol signalling

protocol, as stated in RFC 2205 and RFC 2210, in order to request a specific

QoS from the network to be used by a data stream.

NA - -

STLF-NA-TRD-REQ-1410

(OPT)

RSVP requests shall propagate through Satlife network following the same

path by which the data will be routed, as the RCST shall not end the RSVP

messages.

NA - -

STLF-NA-TRD-REQ-1420

(OPT)

RCST IDU shall be able to translate into satellite units and particular

bandwidth requirements RSVP requests.

NA - -

STLF-NA-TRD-REQ-1430

(OPT)

A minimum bandwidth shall be assure for RSVP signals requests to avoid

high delays for allocating the bandwidth.

NA - -

STLF-NA-TRD-REQ-1440

(OPT)

The use of SIP/COPS shall follow ETSI TR 102 157. NA -

STLF-NA-TRD-REQ-1450

(OPT)

COPS protocol shall allow interaction between the QoS management module

located at the MS and an external (to the satellite network) SIP proxy.
