RSS topologyBest Practices for VMware ESX Server 3.0 Backup on NetApp
White Paper With either topology, it is possible to mount the backup copy as a second disk on a helper VM. The goal of the VMware/NetApp solution is to provide a crash-consistent process that takes advantage of snapshot-based backups. [24 Jul 2008]
QoS Topology Control in Ad Hoc Wireless Networks
White Paper This paper discusses the energy efficient QoS topology control problem in ad hoc wireless networks. Given a set of nodes in a plane, end-to-end traffic demands and delay bounds between node pairs, the problem is to find a network topology that can... [18 Jul 2008]
A Network Management Architecture for Robust Packet Routing in Mesh Optical Access Networks
White Paper The architecture can be utilized with an arbitrary, link-redundant mesh network (node-redundancy is necessary only to handle all node failures), and assumes neither the use of a star topology nor the ability to embed such a topology within the... [18 Jul 2008]
Reconfiguration of MPLS/WDM Networks Using Simulation-Based Markov Decision Processes
White Paper This paper presents a new approach to the problem of logical topology reconfiguration in congested WDM networks using simulation-based multi-time scale Markov Decision Processes (MDP). Previous work considered total reconfiguration of the network... [18 Jul 2008]
A Novel Method for QoS Provisioning With Protection in GMPLS Networks
White Paper In this paper, a new optimal policy is introduced to determine, adapt, and protect the Generalized MultiProtocol Label Switching (GMPLS) network topology based on the current traffic load. The Integrated Traffic Engineering (ITE) paradigm provides... [18 Jul 2008]
The Problem of Upstream Traffic Synchronization in Passive Optical Networks
White Paper PON may be deployed as a bus, ring, or tree topology. Recently Passive Optical networks gained a lot of attention as a possible solution to the broadband local access network. While it is a very cost-effective solution, it has some unique problems... [18 Jul 2008]
Adaptive Routing Protocol for QoS in Two-Layered Satellite IP Networks
White Paper Dynamic topology of the network and constraints on key system resources such as on-board CPU and memory are essential points to be considered for an efficient system design. Non-GEOstationary (NGEO) satellite networks can meet the requirements of... [18 Jul 2008]
Bufferless All-Optical Networking With Erasure Codes
White Paper The purpose of this paper is to report results of a simulation experiment to evaluate several topology-based routing algorithms for deflection routing in unstructured networks of switches in order to determine how much packet level erasure... [18 Jul 2008]
Traffic Engineering and Network Management System for QoS-Guaranteed DiffServ Provisioning
White Paper Using the proposed traffic engineering functions for DiffServ-over-MPLS network, the Internet Service Provider (ISP) can easily configure Diffserv-over-MPLS traffic flows among customer's distributed sites, and can provide guaranteed end-to-end... [18 Jul 2008]
Energy-Aware and QoS Routing in 6LoWPAN Mesh Networks
White Paper A routing protocol is needed for the mesh topology approach, which must take into account the very limited features of the network This paper proposes an energy aware QoS routing protocol for 6LoWPAN based on extension of 6LoWPAN Ad Hoc Routing... [18 Jul 2008]
Effectiveness of Shared Risk Link Group Auto-Discovery in Optical Networks
White Paper This paper evaluates location-based methods for the auto-discovery of SRLGs, guided by the topology and design of AT&T's next generation transport network. Shared Risk Link Groups (SRLGs), introduced in, provide inputs necessary to plan for... [18 Jul 2008]
Non-Adaptive Fault Diagnosis for All-Optical Networks Via Combinatorial Group Testing on Graphs
White Paper The efficiency of these schemes often depends on the network topology; in many cases it shows that these schemes are near-optimal by providing tight lower bounds. This paper considers the fault diagnosis problem in all-optical networks, focusing on... [18 Jul 2008]
Ultra Low Latency Optical Networks
White Paper Employed techniques include a non-blocking, bufferless topology, single pulse packets incorporating Wavelength Division Multiplexing (WDM) for both routing header and payload data, and ultra-fast electro optical interfaces built from commercially... [18 Jul 2008]
A Review of Traffic Grooming in WDM Optical Networks: Architectures and Challenges
White Paper Most previous research on traffic grooming is mainly based on the ring network topology. The transmission capacity of a link in today's optical networks has increased significantly due to Wavelength-Division Multiplexing (WDM) technology. [18 Jul 2008]
ASAP: An Adaptive QoS Protocol for Mobile Ad Hoc Networks
White Paper RSVP, are not applicable in MANETs, because they cannot cope with MANET's highly dynamic topology. With the increasing widespread use of wireless technologies, the need arises for QoS provisioning mechanisms for multimedia applications in wireless... [17 Jul 2008]
