Increasing negotiation performance at the edge of the network [article]

Sam Vente, Federico Cerutti
2020 arXiv   pre-print
This can lead to unnecessarily long negotiations when, for example, negotiations are impossible, risking to waste bandwidth that is a precious resource at the edge of the network.  ...  While alternative protocols exist which alleviate this problem, these solutions are too complex for low power devices, such as IoT sensors operating at the edge of the network.  ...  the edge of a network.  ...

Congestion control scheme in optical packet switched networks

Zheng Lu, D.K. Hunter, I.D. He
2006 2006 Optical Fiber Communication Conference and the National Fiber Optic Engineers Conference  
This paper proposes a congestion control scheme for optical packet switched networks, for use with edge smoothing and reduced core optical buffers.  ...  In our previous work [3, 4] , the rate of traffic is predicted, and it is smoothed at the edge with negotiated sending rate.  ...  For TACC nets, at low load, the negotiation interacts with the filling of slots, therefore there is no decreasing trend; the delay in TACC nets steadily increases with load, due to the increased delay  ...

Factors Influencing Edge Smoothing Effects in Optical Packet Switched Networks

Zheng Lu, David Hunter
2006 2006 International Conference on Photonics in Switching  
Through simulation, the effect of this edge smoothing scheme in reducing optical packet loss in the core is quantified, and compared to the performance when using containerization without any traffic smoothing  ...  It smoothes external traffic at optical edge ingress switches, so that the traffic pattern flowing into the core is more regular.  ...  Under the same traffic loading, increasing the number of aggregated flows increases packet loss, especially with few flows.  ...

Design and implementation of Dynamic Service Negotiation Protocol (DSNP)

Jyh-Cheng Chen, Venkatesh Sarangan, Anthony McAuley, Shinichi Baba, Yoshihiro Ohba, Zong-Hua Liu
2006 Computer Communications  
This paper describes the design principles and implementation of Dynamic Service Negotiation Protocol (DSNP). DSNP is a protocol to negotiate the Service Level Specification (SLS) at the IP layer.  ...  It can be used for service negotiation from host to network, network to host, and network to network.  ...  In addition, once a MS changes its QoS profile, the same transaction for updating the database must be performed at all the edge routers, which is time consuming.  ...

Distributed Busacker–Gowen algorithm for end-to-end QoS pipe negotiation in X-domain networks

Hélia Pouyllau, Stefan Haar
2008 Annales des télécommunications  
Such a distribution would indicate for each chain of a pipe, the connection ow it may accept. In this paper, we address the pipe negotiation problem as a network ow problem.  ...  The proposed negotiation process results in the selection of aggregated contract chains, called pipes, and a distribution between them.  ...  Performances In this section, we present the evaluation of the runtime performances of negotiation algorithms.  ...

Dynamic QoS Management for Interactive Multimedia in Integrated 4G/5G Networks

Kirti Keshav, Ashish Pradhan, T Srinivas, Pallapa Venkataram
2021 EAI Endorsed Transactions on Mobile Communications and Applications  
These requirements include higher uplink and downlink throughput requirement, low latency, and consistent throughput even at the cell edge.  ...  While 4G/5G networks do have a QoS mechanism to handle multiple varieties of traffic requirements, they are passive. At best, initial negotiated QoS are changed on a reactive basis.  ...  For a consistent experience of complete immersion everywhere, consistent throughput is required even at the cell edge.  ...
