Abstract

For the performance analysis of ATM networks carrying Variable Bit Rate (VBR) MPEG video sequences there is a need for appropriate video traffic models. In this paper, we discuss Markov chain models for this specific type of traffic with respect to several statistical properties and their ability to predict cell losses at buffers of ATM multiplexers. We intentionally selected a simple model class to check for its appropriateness to model a complex traffic type. The results of this paper show that Markov chain models can be used efficiently for MPEG video traffic under the following conditions. The Group of Pictures' (GOP) generation process should be modeled rather than the frame process. If the performance measures depend on the correlation properties of the video traffic the scene process should also be considered in the course of the model development.

Passive optical network (PON) supported networking
2014, Optical Switching and Networking
In this editorial, we first set the context for the subject matter of this special issue on passive optical network (PON) supported networking. This context includes a discussion of optical networking in all segments of a global communication network and the emphasis of the importance of PONs in the access network as well as their role supporting other communication network technologies. We follow this broader context with an introduction to the articles appearing in this special issue. Lastly, we conclude this editorial with a broad outlook to the future of PONs in communication networks.
A fair scheduling discipline for Ethernet passive optical networks
2009, Computer Networks
We propose a novel policy for scheduling upstream flows in Ethernet passive optical networks. This policy, called proportional sharing with load reservation (PSLR), provides bandwidth guarantees on a per-flow basis and redistributes the unused bandwidth among active flows in proportion to their priority level. We establish convergence conditions for the PSLR policy and show that it provides a fair service distribution among the flows. Moreover, we establish bounds for the backlog and delay on a per-flow basis, thus enabling a network to provide its users with absolute performance guarantees.
Internet traffic modeling by means of Hidden Markov Models
2008, Computer Networks
Citation Excerpt :
In our work, instead, we concentrate on the traffic generated by single sources which is then mixed in network links, therefore here we do not consider queue analysis. In [21], a Markov-based model has been proposed and applied to variable bitrate MPEG traffic; GOP layer traffic characteristics for MPEG video traffic and sources are constructed from MPEG1 encoded video sequences. The same model has been applied to other traffic types (e.g, VoIP traffic).
In this work, we propose a Hidden Markov Model for Internet traffic sources at packet level, jointly analyzing Inter Packet Time and Packet Size. We give an analytical basis and the mathematical details regarding the model, and we test the flexibility of the proposed modeling approach with real traffic traces related to common Internet services with strong differences in terms of both applications/users and protocol behavior: SMTP, HTTP, a network game, and an instant messaging platform. The presented experimental analysis shows that, even maintaining a simple structure, the model is able to achieve good results in terms of estimation of statistical parameters and synthetic series generation, taking into account marginal distributions, mutual, and temporal dependencies. Moreover we show how, by exploiting such temporal dependencies, the model is able to perform short-term prediction by observing traffic from real sources.
