Zero Jitter for Deterministic Networks without Time-synchronization

Jinoo Joung, Juhyeok Kwon
2021 IEEE Access  
The worst case in strict priority scheduler, or any other work-conserving packet scheduler, happens when the maximum burst of packets from all the flows arrive almost simultaneously, and the packet under  ...  Finding a non-conflicting schedule of packets is proven to be NP-complete, even with fixed sized slots similar to a TDMA [7] .  ...

A framework for deterministic delay guarantee in OBS networks

Guoqiang Hu, Carla Raffaelli
2010 Photonic network communications  
Furthermore, the end-to-end (E2E) delay requirements of premium services need queueing delay guarantee in network nodes throughout the transmission path.  ...  In OBS networks, the delay of control packets in the switch control unit (SCU) of core nodes influences burst loss performance in the optical switching and should be constrained.  ...  Acknowledgments The study described in this article was carried out with the support of the BONE-project ("Building the Future Optical Network in Europe"), a Network of Excellence funded by the European  ...

Dynamic load balancing without packet reordering

Srikanth Kandula, Dina Katabi, Shantanu Sinha, Arthur Berger
2007 Computer communication review  
Splitting traffic at the granularity of packets quickly and accurately assigns the desired traffic share to each path, but can reorder packets within a TCP flow, confusing TCP congestion control.  ...  FLARE is simple and can be implemented with a few KB of router state.  ...  RELATED WORK The work closest to FLARE is in the context of circuit and optical switching It observes that switching user-data bursts allows circuits to be established once for each burst, and a single  ...

Discharging the Network From Its Flow Control Headaches: Packet Drops and HOL Blocking

Nikolaos Chrysos, Lydia Chen, Christoforos Kachris, Manolis Katevenis
2016 IEEE/ACM Transactions on Networking  
The key idea is to move the congestion avoidance burden from the data fabric to a scheduling network, which isolates flows using per-flow request counters.  ...  The scheduling network comprises per output arbiters that grant data packets after reserving space for them in the buffer memories in front of fabric outputs.  ...  The authors would like to thank the anonymous reviewers for their extensive feedback that greatly helped us to improve the quality of present manuscript.  ...

Efficient mobile multimedia streaming

Cheng-Hsin Hsu
2010 ACM SIGMultimedia Records  
Second, any decision points that would lead to a burst shorter than the minimum burst size are suppressed for that iteration.  ...  Within each scheduling window, the dynamic scheduling allocates each video stream a burst with size of its aggregate frame size in that scheduling window.  ...  schedule a burst from times t to t n for s, where window p of s has the smallest z s p 11 . among all windows p ′ with x s p ′ ≤ t and z s p ′ > t, and t n is the time of the next 11.  ...

Technical Report: Efficient Buffering and Scheduling for a Single-Chip Crosspoint-Queued Switch [article]

Zizhong Cao, Shivendra S. Panwar
2014 arXiv   pre-print
Scheduling is also performed inside the switching core, and does not rely on latency-limited communications with input or output line-cards.  ...  We also design scheduling algorithms to maintain the correct packet order even while employing multi-path switching and resolve contentions caused by multiplexing.  ...  It works well when buffer size is large, but is inefficient when there is limited space and the incoming traffic is bursty and non-uniform.  ...
