About SNS3

Satellite Network Simulator 3 (SNS3) is a satellite network extension to Network Simulator 3 (ns-3) platform. ns-3 is a discrete event simulator for networking research licensed under General Public License v2 (GPLv2). SNS3 models a full interactive multi-spot beam satellite network with a geostationary satellite and transparent star (bent-pipe) payload. The reference satellite system consists of 72 spot-beams with an European coverage, 5 gateways and Ka-band frequencies.

SNS3 is a dynamic system simulator, which works at a physical level burst resolution. Its use cases range from full network level performance to a single user Quality of Service verification. SNS3 is built to be modular and flexible to provide extensibility to different satellite communication networks and use cases.

SNS3 has not yet been contributed to baseline ns-3. SNS3 team is working on it and a contribution is expected in the near future.

Features

SNS3 implements DVB-RCS2 (Digital Video Broadcast – Return Channel via Satellite – 2nd generation) and DVB-S2 (Digital Video Broadcasting – Satellite – 2nd generation) specifications in return and forward link. Satellite network features include e.g.

Adaptive Coding and Modulation (ACM)
Return and forward link scheduling
Demand Assignment Multiple Access (DAMA): Constant Rate Allocation (CRA), Rate-Based Dynamic Capacity (RBDC), Volume-Based Dynamic Capacity (VBDC), Free Capacity Allocation (FCA)
Random Access (RA): Slotted ALOHA and Contention Resolution Diversity Slotted ALOHA (CRDSA)
Generic Stream Encapsulation (GSE)
Return Link Encapsulation (RLE)
Automatic Repeat reQuest (ARQ)
Multi-beam satellite antenna gain patterns
Packet-by-packet SNIR computation
Packet-by-packet co-channel and intra-beam interference tracking
Weather traces, Land-Mobile Satellite (LMS) channel
Error models

In addition, SNS3 benefits from numerous existing ns-3 models and features, such as various terrestrial air interfaces (LTE, WiFi), network and transport layer models, application models, real-time emulation support and direct code execution.

Use cases

Simulators and emulators provide deep insight on networking building blocks in a relatively fast and cost-effective manner without a need for early-stage prototypes. Simulations and emulations may have complementary roles; e.g. SNS3 simulations can assess full-blown network performance and SNS3 emulations can focus on protocol interaction. Example SNS3 use cases include e.g.

Algorithm and protocol design, development and optimization
Proof-of-concepts to support product development
Full satellite system performance assessment and end user quality of service verification
Higher layer protocol and application performance optimization
Visual satellite network demonstrations
