Providing QoS to connection-less packet-switched NoC by implementing diffserv functionalities

M.D. Harmanci, N.P. Escudero, Y. Leblebici, P. Ienne
2004 International Symposium on System-on-Chip, 2004. Proceedings.  
This novel implementation based on connection-less communication impmves the compmmise between guaranteeing dvferent trafic requirements and resource utilization, which is not eficiently granted in connection-oriented  ...  QoS is not intrinsic in most of todays NoC solutions, although it is crucial for global predictabiliiy and design reuse.  ...  Although connection-less schemes provide a poorer QoS support as connection-oriented techniques, this can he greatly improved by implementing additional services such as DiffServ on top of it.  ...

QoS in Networks-on-Chip – Beyond Priority and Circuit Switching Techniques [chapter]

Aline Mello, Ney Calazans, Fernando Moraes
2009 IFIP International Federation for Information Processing  
These QoS targeted NoC templates usually provide specialized structures to allow either the creation of connections (circuit switching) or the assignment of priorities to connectionless flows.  ...  If this problem is tackled by oversimplifying the modeling phase, errors may arise, leading to NoC parameterization that is poorly adapted to achieve the required QoS.  ...  Present NoC implementations providing support to QoS try to achieve performance requirements at design time.  ...

2016 IEEE Communications Magazine  
This paper presents innovative techno-economical solutions to provide these areas with cellular voice and data services.  ...  However, isolated rural areas (sparsely inhabited by low-income population) have been disregarded because classical access and backhaul technologies do not assure the return on investment.  ...  The traffic supported by the backhaul concentrates on the gateway router located in Negro Urco, which connects to the MNO's backhaul via a VSAT in Ku-band whose main NOC is located in Lima.  ...
