We propose a new transport protocol, TCP Boston, that turns ATM's 53-byte cell-oriented switching architecture into an advantage for TCP/IP. At the core of TCP Boston is the Adaptive Information Dispersal Algorithm (AIDA), an efficient encoding technique that allows for dynamic redundancy control. AIDA makes TCP/IP's performance less sensitive to cell losses, thus ensuring a graceful degradatio...

Wavelength-division multiplexing has emerged as an important physical layer technology. Optical transmission provides a physical layer capable of carrying bits at the speed of the order of a gigabit per second. Optical burst switching is proposed to overcome the shortcomings of conventional WDM deployment, such as lack of fine bandwidth granularity in wavelength routing and electronic speed bot...

For rhombohedral multiferroelectrics, non-180° ferroelectric domain switching may induce ferroelastic and/or (anti-)ferromagnetic effect. So the determination and control of ferroelectric domain switching angles is crucial for nonvolatile information storage and exchange-coupled magnetoelectric devices. We try to study the intrinsic characters of polarization switching in BiFeO3 by introducing ...

In this work, we first briefly introduce the concept of IP flow classification on a general conceptual level. The intention is to rise above the technological details and create a conceptual point of view on flow classification and closely related issues. Then we move on to study and compare earlier flow classification methods such as the all and selected flow classifier and the packet count fl...

In this paper we present a policy-based architecture for aggregating (grooming) IP/MPLS flows (packet-based LSPs) within lightpaths taking into account the possibility of having to cope with further transport faults. The defined policies try to minimize the negative impact when a failure is detected in the optical transport network. Such policies deal with 1+1, 1:1 and 1:N schemes of protection...

In this half-day tutorial, we present the current state-of-theart in optical networks. We begin by discussing the various optical devices used in optical networks. Then, we present wavelength-routed networks, which is currently the dominant architecture for optical networks. We discuss wavelength allocation policies, calculation of call blocking probabilities, and network optimization technique...

This paper firstly analyzes two movement detection schemes—eager cell switching scheme and lazy cell switching scheme. Then, aiming at their drawbacks, two improved solutions—region adjustment algorithm and improved region adjustment algorithm are proposed. In our solutions, the region is dynamically adjusted by current information of the link bandwidth in order to reduce the unnecessary increa...

This paper proposes an approach to Traffic Engineering that uses Differentiated Services (diffserv) and Multi-Protocol Label Switching (MPLS) to provide quantitative QoS guarantees over an IP network. An algorithm that determines QoS-constrained routes is proposed and a framework that uses such an algorithm is outlined. This framework removes the responsibility of QoS guarantees from the core n...

This document describes the applicability of Multiprotocol Label Switching (MPLS) to traffic engineering in IP networks. Special considerations for deployment of MPLS for traffic engineering in operational contexts are discussed and the limitations of the MPLS approach to traffic engineering are highlighted.
