|Solutions for Sustaining Scalability in Internet Growth
Mohamed Boucadair, David Binet.
An ever-increasing thirst for information in recent years among consumers, researchers, and the general population has necessitated continuous growth of internet architecture and accessibility, an issue which, if not addressed properly, may inhibit the growth of the internet as a whole.Solutions for...
Issues with Current Internet Architecture
Mohamed Boucadair, David Binet.
Internet actors should work on an action plan to mitigate the increase of Routing Information Base (RIB) and Forwarding Information Base (FIB) table sizes and the load induced by routing updates churn (BGP Instability Report, n.d.).
Inter-Domain Traffic Engineering using the Origin Preference Attribute
Rolf Winter, Iljitsch van Beijnum.
Inter-domain Traffic Engineering (TE) is an important aspect of network operation both technically and economically. Outbound Traffic Engineering is less problematic as routers under the control of the network operator are responsible for the way traffic leaves the network. The inbound direction is...
On the Aggregatability of Router Forwarding Tables
Yaoqing Liu, Xin Zhao, Lan Wang, Beichuan Zhang.
In this book chapter, the authors first present Optimal Routing Table Constructor (ORTC), an optimal one-time FIB aggregation algorithm that preserves strong forwarding correctness. The authors then present four-level FIB aggregation algorithm(s) that can handle dynamic routing updates while...
APT: A Practical Tunneling Architecture for Routing Scalability
Dan Jen, Michael Meisel, Daniel Massey, Lan Wang, Beichuan Zhang, Lixia Zhang.
The global routing system has seen a rapid increase in table size and routing changes in recent years, mostly driven by the growth of edge networks. This growth reflects two major limitations in the current architecture: (a) the conflict between provider-based addressing and edge networks’ need for...
Routing Architecture of Next-Generation Internet (RANGI)
Xiaohu Xu, Meilian Lu.
This chapter describes a new Identifier/Locator split architecture, referred to as Routing Architecture for the Next Generation Internet (RANGI), which aims to deal with the routing scalability issues. Similar to the Host Identity Protocol (HIP) architecture, RANGI also introduces a host identifier...
Routing Optimization for Inter-Domain Traffic Engineering Under Identifier Network
Hongke Zhang, Changqiao Xu, Wei Su, Hongbin Luo.
Based on Identifier Network, we propose a solution for traffic engineering, which can be divided into two distinct parts: End-to-End traffic engineering and Neighbor-to-Neighbor traffic engineering. For each scenario, we develop a routing decision method for both routers and other network entities...
The Map-and-Encap Locator/Identifier Separation Paradigm: A Security Analysis
Damien Saucez, Luigi Iannone, Olivier Bonaventure.
The chapter does not overview the merits of the Locator/Identifier separation paradigm. Rather, the aim is to provide a thorough analysis of the security aspects, assessing the security level of the architecture and providing recommendations on possible practices to improve it.
Waveband Switching: A Scalable and Cost Efficient Solution for the Internet Backbone
Yang Wang, Vishal Anand, Xiaojun Cao.
In this chapter, the authors describe and review some of the recent research on WBS, including Multi-Granular optical cross-connect (MG-OXC) architectures that can switch traffic at different granularities. The authors focus on the dynamic online WBS problem, and describe and analyze two reconfigurable...
Security, Design, and Architecture for Broadband and Wireless Network Technologies
While wireless technologies continue to provide an array of new challenges and multi-domain applications for business processes and solutions, there still remains to be a comprehensive understanding of its various dimensions and environments.Security, Design, and Architecture for Broadband and Wireless...
Joint Angular and Time Diversity of Multi-Antenna CDMA Systems in Wireless Fading Channels
Feng She, Hsiao Hwa Chen, Hongyang Li.
In this paper, a multi-antenna based receiver structure for direct sequence code division multiple access (DS/CDMA) system is proposed. The proposed scheme exploits the excellent time resolution of a CDMA RAKE receiver and uses an antenna array beamforming structure to resolve multipath returns in both...
Improving WLAN Performance by Modifying an IEEE 802.11 Protocol
Nurul I. Sarkar.
One of the limitations of the IEEE 802.11 distributed coordination function (DCF) protocol is its low bandwidth utilization under medium-to-high traffic loads resulting in low throughput and high packet delay. To overcome performance problems, traditional IEEE 802.11 DCF (“DCF”) protocol is modified to...
Insights from Experimental Research on Distributed Channel Assignment in Wireless Testbeds
Felix Juraschek, Mesut Günes, Matthias Philipp, Bastian Blywis.
This article presents the DES-Chan framework for experimental research on distributed channel assignment algorithms in wireless mesh testbeds. The implementation process of channel assignment algorithms is a difficult task for the researcher since common operating systems do not support channel...
HTTP Traffic Model for Web2.0 and Future WebX.0
Vladimir Deart, Alexander Pilugin.
This article presents a method of estimation for HTTP traffic quality service parameters mean delay and lost packets percentage. This method, based on statistic measurements, includes simulation and analytical modeling. Statistical HTTP traffic models presented earlier take into account typical...
Performance Evaluation of a Three Node Client Relay System
Sergey Andreev, Olga Galinina, Alexey Vinel.
In this paper, the authors examine a client relay system comprising three wireless nodes. Closed-form expressions for mean packet delay, as well as for throughput, energy expenditure, and energy efficiency of the source nodes are also obtained. The precision of the established parameters is verified by...
BER Fairness and PAPR Study of Interleaved OFDMA System
Sabbir Ahmed, Makoto Kawai.
For an OFDMA system, the role of interleavers is analyzed to ensure fairness of BER performance among the active users and investigate their respective PAPR properties. In this paper, the authors consider a generic system and show that for a slowly changing multipath channel, individual user’s BER...
Lifetime Maximization in Wireless Sensor Networks
Vivek Katiyar, Narottam Chand, Surender Soni.
One of the fundamental requirements in wireless sensor networks (WSNs) is to prolong the lifetime of sensor nodes by minimizing the energy consumption. The information about the energy status of sensor nodes can be used to notify the base station about energy depletion in any part of the network. An...
Doubly Cognitive Architecture Based Cognitive Wireless Sensor Networks
Sumit Kumar, Deepti Singhal, Garimella Rama Murthy.
Scarcity of spectrum is increasing not only in cellular communication but also in wireless sensor networks. Adding cognition to the existing wireless sensor network (WSN) infrastructure has helped. As sensor nodes in WSN are limited with constraints like power, efforts are required to increase the...
