Behavior of TCP-like elastic traffic at a buffered bottleneck router

H.-P. Schwefel
Proceedings IEEE INFOCOM 2001. Conference on Computer Communications. Twentieth Annual Joint Conference of the IEEE Computer and Communications Society (Cat. No.01CH37213)  
However, since TCP reacts to existing congestion, the throttling mechanism is only activated when the buffer-occupancy at the bottleneck router exceeds a certain threshold.  ...  The impact of such a flowcontrol mechanism on the characteristics of the incoming traffic as well as on the performance behavior at the bottleneck router is discussed and illustrated by numerical results  ...  ACKNOWLEDGMENTS The research for this paper was performed while the author was enjoying the hospitality of the Network Design and Performance Analysis Department at AT&T Labs, NJ, USA.  ...

On Performance Evaluation of Handling Streaming Traffic in IP Networks Using TFRC Protocol [chapter]

Kacper Kurowski, Halina Tarasiuk
2008 Lecture Notes in Computer Science  
Moreover, we check TFRC performance when it is sharing bottleneck with different versions of TCP.  ...  This paper deals with the performance evaluation of handling streaming traffic in IP best effort networks using TFRC protocol.  ...  It consists of two IP routers R1 and R2 (with FIFO/drop-tail queue), a number of sources (it depends on evaluated scenario), associated with TFRC, TCP or UDP senders, and a number of receivers.  ...

Best Effort Session-Level Congestion Control

Siddharth Ramesh, Sneha Kumar Kasera
2007 2007 IEEE International Conference on Network Protocols  
Congestion caused by a large number of interacting TCP flows at a bottleneck network link is different from that caused by a lesser number of flows sending large amounts of data the former would require  ...  Furthermore, our session control mechanisms do not require any per-flow state or computation at the routers, make no assumption about input traffic characteristics and requirements, avoid starvation of  ...  The bottleneck router buffer is set (in terms of packets) as a product of the bandwidth and the average delay of all flows passing through it.  ...

ECN-capable TCP-friendly Layered Multicast Multimedia Delivery

Robert R. Chodorek, Agnieszka Chodorek
2009 2009 11th International Conference on Computer Modelling and Simulation  
In the paper, a simulation model of ECN-capable multicast multimedia delivery in ns-2 environment is discussed.  ...  TCP-Friendliness denotes that receiverdriven architecture behaves under congestion like the TCP protocol.  ...  Core routers were connected with a bottleneck link at 2 Mbps (topology T1 and T2) and 6.5 Mbps (topology T3) and propagation delay of 10 ms. The intermediate router (topology T3) used the RED queue.  ...

On Providing End-To-End QoS Introducing a Set of Network Services in Large-Scale IP Networks [chapter]

E. Tsolakou, E. Nikolouzou, S. Venieris
2002 Lecture Notes in Computer Science  
Traffic Classes provide the traffic handling mechanisms for each Network Service and are composed of a set of admissio n control rules, a set of traffic conditioning rules and a per-hop behavior (PHB).  ...  Each network service is appropriate for a specific type of traffic and is realized through its own network mechanisms, which are the Traffic Classes.  ...  The PMM is expected to carry a mixture of TCP and non-TCP traffic. These flows require a minimum bandwidth, which must be delivered at a high probability.  ...

Energy saving and network performance

Carla Panarello, Alfio Lombardo, Giovanni Schembra, Luca Chiaraviglio, Marco Mellia
2010 Proceedings of the 1st International Conference on Energy-Efficient Computing and Networking - e-Energy '10  
The AWM characteristics allow to detect whether a waste of energy is playing out, whereas EARTH is aimed at invoking power management primitives at the hardware level to precisely control the current capacity  ...  More specifically, we propose a Green router (Grouter) implementing a congestion control technique named Active Window Management (AWM) coupled with a new capacity scaling algorithm named Energy Aware  ...  This is due to the elastic nature of traffic, and of TCP in particular, so that, if capacity is reduced/increased at the bottleneck link, the instantaneous traffic offered by TCP sources would reduce/increase  ...

Elastic-TCP: Flexible Congestion Control Algorithm to Adapt for High-BDP Networks

Mohamed A. Alrshah, Mohamed A. Al-Moqri, Mohamed Othman
2019 IEEE Systems Journal  
Moreover, it is worth noting that the new Elastic-TCP presents lower sensitivity to the variation of buffer size and packet error rate than the other TCPs, which grants high efficiency and stability.  ...  In order to increase TCP flexibility to adapt for high-BDP networks, we propose a new delay-based and RTT-independent congestion control algorithm (CCA), namely Elastic-TCP.  ...  That is why, only FTP traffic is used in this work because it is a long-lived TCP traffic type that represents a great portion of Internet traffic.  ...

Variants of the Constrained Bottleneck LAN Edge Link in Household Networks

Koffka Khan, Wayne Goodridge
2019 International journal of advanced networking and applications  
Some of these are well documented in the literature but we intend to highlight the major conditions at a bottleneck link in household LANs.  ...  We explore these conditions and evaluate the performance of heuristic adaptive video players. ELASTIC and PANDA players are evaluated.  ...  Because of this the home router becomes a bottleneck for network traffic. We call this the constrained bottleneck link problem.  ...

Elasticity Detection: A Building Block for Internet Congestion Control [article]

Prateesh Goyal, Akshay Narayan, Frank Cangialosi, Srinivas Narayana, Mohammad Alizadeh, Hari Balakrishnan
2020 arXiv   pre-print
To estimate elasticity, Nimbus modulates the flow's sending rate with sinusoidal pulses that create small traffic fluctuations at the bottleneck link, and measures the frequency response of the rate of  ...  If cross traffic is inelastic, then a sender can control queueing delays while achieving high throughput, but in the presence of elastic traffic, it may lose throughput if it attempts to control packet  ...  Further, if elastic cross traffic is using a delay-controlling scheme like Vegas, then Nimbus could miss out on an opportunity to control delays if it uses a buffer-filling TCP-competitive algorithm.  ...

TCP congestion signatures

Srikanth Sundaresan, Mark Allman, Amogh Dhamdhere, Kc Claffy
2017 Proceedings of the 2017 Internet Measurement Conference on - IMC '17  
TCP congestion control affects the round-trip time (RTT) of packets within the flow (i.e., the flow RTT): an endpoint sends packets at higher throughput, increasing the occupancy of the bottleneck buffer  ...  In TCP terms, we re-articulate the question: was a TCP flow bottlenecked by an already congested (possibly interconnect) link, or did it induce congestion in an otherwise idle (possibly a last-mile) link  ...  When a TCP flow starts on an otherwise uncongested path, it drives buffering behavior in the bottleneck link by increasing its occupancy.  ...

Network interface power management and TCP congestion control: a troubled marriage

Carla Panarello, Alfio Lombardo, Giovanni Schembra, Michela Meo, Marco Mellia, Marco Ajmone Marsan
2016 Australian Journal of Electrical & Electronics Engineering  
Optimizing the tradeoff between power saving and Quality of Service (QoS) in the current Internet is a challenging research objective, whose difficulty stems also from the dominant presence of TCP traffic  ...  , and its elastic nature.  ...  However, in our study it can be interesting to also look at the case of a rapid increase of the arrival rate at router N1, to see how it may affect the performance of both TCP and capacity scaling.  ...

Integration of Streaming and Elastic Traffic: A Fixed Point Approach

Hassan Hassan, O Brun, Jean-Marie GARCIA, David Gauchard
2008 Proceedings of the First International ICST Conference on Simulation Tools and Techniques for Communications Networks and Systems  
We present a fixed point approach to evaluate the quality of service of streaming traffic multiplexed with elastic traffic in multi-service networks.  ...  First, we handle elastic traffic and streaming traffic separately, and then we derive a general fixed point formulation integrating both types of traffic in best effort networks.  ...  On the other hand, increasing the loss rate at router interface makes TCP connection reduce its input rate until a stability point is found.  ...
