Abstract [en]

In this article, we present the challenges faced by communication networks in delivering high-quality video content to mobile and stationary devices serving CDN users. Starting with Content Distribution Network types, an overview is given in order to show how this field develops on the research as well as on the commercial side. Research or academic CDNs, new aspects and features are tested to add scalability and functional features to known systems and prototypes. On the other hand, commercial CDNs serve alternatively customers that use broadcasting services. We also show which performance metrics such as quality of experience (QoE) and time to first byte (TTFB) best capture the dynamics of traffic and services in CDNs. The core of this paper is our proposed network architecture for CDN providers/operators. The architecture combines video multicast optimized trees and cross-layer coordination between the physical DWDM layer (L1) and network layer (L3) for achieving higher efficiency and lower latency values for live streaming and on demand (VoD) video. Due to the pilot implementation of the presented concept being limited in scale, we use simulations in order to perform proof-of-concept on a sufficiently large environment. Results show that there is a strong correlation between the TTFB and QoE metrics with the former taking on values as low as 75 msec in a national 3-tier network. Ultimately, our aim is to familiarize readers with the field of CDNs and also to help them see how network research especially in the architectural, protocol design, and cross-layer design help bring applications in this field to a quality level acceptable by a large community of users.

Abstract [en]

In this paper we present some contemporary examples of research-oriented as well as commercial content delivery networks (CDN)s. We discuss how both types of CDNs complement each other in tackling the posed technical and commercial challenges. We also show which performance metrics such as quality of experience (QoE) and time to first byte (TTFB) best capture the dynamics of traffic and services in CDNs. The core of this paper is our proposed network architecture for CDN providers/operators. The architecture combines video multicast optimized trees and cross-layer coordination between the physical DWDM layer (L1) and network layer (L3) for achieving higher efficiency and lower latency values for live streaming and on demand (VoD) video. Due to the pilot implementation of the presented concept being limited in scale, we use simulations in order to perform proof-of-concept on a sufficiently large environment. Results show that there is a strong correlation between the TTFB and QoE metrics with the former taking on values as low as 75 msec in a national 3-tier network.

Abstract [en]

IP Mobility Management allowing for handover and location management to be handled by the network layer has been around for a couple of 20 years or so now. A number of protocols have been proposed including the GPRS Tunneling Protocol (GTP), Mobile IP, Proxy Mobile IP, and the Locator/Identifier Split Protocol (LISP) being the best known and most discussed in the research literature. This paper overviews existing solutions and suggests a new distributed and dynamic mobility management scheme and evaluates it against existing static approaches.

Abstract [en]

The demand for network resources (e.g. forwarding capacity, buffer space) by increasingly used real-time multimedia applications is growing. Moreover, their stringent performance requirements (e.g. delay and jitter bounds) pose challenges on network resource management (RM). RM determines how available resources are modeled and distributed to achieve a performance goal such as assuring forwarding quality to real-time multimedia applications. Improvements to existing RM mechanisms can avoid performance limitations of networks by facilitating more efficient use of scarce resources. For example, in a vehicular to infrastructure (V2I) communication scenario that uses IP Multimedia Subsystem (IMS) lacking RM support for multicast, the 3G downlink quickly becomes a bottleneck although some information is addressed to multiple receivers. The main goal of this thesis is to develop RM algorithms and protocols that improve forwarding capacity utilization and remove performance bottlenecks. An additional goal is to improve the scalability of existing RM mechanisms. Three architectural paradigms are covered to demonstrate the advantages of efficient and systematic network RM: open access networks (OAN), next generation networks (NGN), and heterogeneous access networks (HAN). For OAN, a cross-layer signaling technique called parameter injection was developed. It reduces the signaling overhead and update time for real-time multimedia sessions over Wi-Fi while autonomously selecting the format and CODEC that best match the current resource settings. Within NGN, a resource management protocol is proposed for extending unicast signaling in IMS with multicast capabilities. The contribution uses adaptive and dynamic group size selection to improve resource utilization on the 3G downlink for the signaling and data planes. For HAN, an algorithm is proposed that predicts the best access network for achieving the highest QoE of a real-time multimedia session with the available QoS resources based on regression and statistical learning. In all three paradigms, the provided core contributions serve the common goal of achieving a performance edge in terms of efficiency and systematic operation with a limited amount of network resources.

Abstract [en]

This paper describes iRide (intelligent ride), an IP Multimedia Subsystem (IMS), Multimedia Broadcast Multicast Service (MBMS), and wireless sensor network (WSN) joint application. The core contributions of iRide are: IMS and WSN architectural integration on joint data processing and signaling levels, application logic for increased road safety, and network dimensioning for scalability and performance analysis. The iRide architecture is built and prototyped using IMS standard SIP (Session Initiation Protocol) and DIAMETER signaling together with 3GPP MBMS for more efficient service handling. OPNET simulations are used to conduct network dimensioning and performance analysis. Resource management in systems such as the one presented experiences several challenges in the form of bottlenecks and multicast dynamic group sizing is used as a key technique to make resources on the downlink data planemore efficiently managed. The efficiency of the proposed model for the downlink takes on a Skellam distribution shape which is used for performance modeling.

Abstract [en]

An important feature of the upcoming fourth generation wireless networks is support for heterogeneous radio access technologies in combination with an all-IP type of overall architecture. Operators and users will benefit from a smooth technology transition leveraging existing investments and use a variety of access technologies simultaneously. This paper describes and evaluates an innovative mobility management scheme in such an environment. It does not require any changes to the IP stack in the mobile node and does not introduce any additional overhead to the payload traffic over air interfaces. Furthermore, it does not add any signaling overhead and outperforms existing mobility management schemes for heterogeneous environments in terms of bandwidth consumption. The architecture uses a make-before-break principle for vertical handovers and bidirectional tunneling using various tunneling mechanisms connecting mobile nodes through access networks to a home network. Also, it proposes a packet inspection routine for timely handover execution in the home network. The architecture is evaluated both through analytical calculations and experiments using a voice over IP traffic model.

Abstract [en]

In this paper, we present a scheme for flow management with heterogeneous access technologies available indoors and in a campus network such as 3G and Wi-Fi. Statistical learning is used as a key for optimizing a target variable namely video quality of experience (QoE). First we analyze the data using passive measurements to determine relationships between parameters and their impact on the main performance indicator, namely the video QoE value. The derived weights are used for performing prediction in every discrete time interval of our designed autonomic control loop to know approximately the QoE in the next time interval and be able to perform a switch to another access technology if it yields a better QoE level. This user-perspective performance optimization is in line with operator and service provider goals. QoE performance models for slow vehicular and pedestrian speeds for Wi-Fi and 3G are derived and compared as well.

Abstract [en]

Starting with an efficient mobility management scheme for heterogeneous wireless networks, this paper proposes a solution for AAA handling using a common database for storing user information. Regardless of the access technology selected, user@realm identities are used for authentication, authorization, and accounting. In particular, a new function is introduced in which port-based network access control is used in combination with dynamic host configuration protocol mechanisms for IP address allocation. This way, PPP-based and Ethernet-based access technologies are handled uniformly.Advantages with the proposed solution include: using only standardized mechanisms in the mobile node, as well as in the access networks. Only an additional plug-in in the AAA server (located in the access networks) needs to be deployed.The proposed AAA architecture has been implemented and evaluated in a live experimental environment. Results show authentication and authorization to perform efficiently and seamlessly.

2009 (engelsk)Rapport (Annet vitenskapelig)
Abstract [en]

A system architecture which natively supports cross-layer design in a general sense is an essential prerequisite for enabling communication services in the future heterogeneous Internet. A multitude of cross-layer approaches ranging from clean slate designs to actual implementations of cross-layer links in the standard TCP/IP stack have been suggested during the last decade. Yet, there is no agreement on a systematic integration of cross-layering into the actual Internet architecture. In this article we present a Guided Cross-layering Framework and a roadmap for its deployment in the Internet. We elaborate its key issue of identifying functional invariants in the present communication model. The invariants are the clean protocol stubs of the current TCP/IP stack. We describe the concept of meta-protocols and a design-deployment methodology for the framework. Our main postulate that promises an acceptance of the proposed architecture is the evolutionary, market-driven transformation of the current Internet architecture. On the example of the new ICSP (Integrated Communication and Signaling Protocol) protocol, we demonstrate the integration of CARD (Candidate Access Router Discovery), MIP (Mobile IP), and SIP (Session Initiation Protocol) in our framework which jointly optimize the performance and economic utilities of a multi-cell wireless network operator and the end user.

Abstract [en]

In this paper we present iRide (intelligent ride), an IP Multimedia Subsystem (IMS) application for warning drivers about hazardous situations on the road. iRide takes real-time information about road conditions and traffic situations from a wireless sensor network installed directly in the road surface. Upon logging to the iRide system, users start to receive periodic updates about the situation on the road along their route ahead. iRide is able to predict hazardous situations like slippery surface or dangerous distance to the nearest car and help drivers avoid accidents. We describe the service and the supporting network architecture of iRide. We discuss the major challenges associated with designing an IMS application for ITS, an intelligent transport system. Having a prototype implementation working on a small scale, we take it to the next step to perform system dimensioning and then verify the feasibility of having such a system using OPNET simulations.
