Why You Need Email Encryption: Use Case Scenarios
White Paper DSS, GLBA, HIPAA, OMB, PCI, and PIIG are just a few of the standards and regulations that place additional constraints on how data is stored, processed, and transmitted. "Identity theft is a top concern for consumers right now, so we can't let... [05 Aug 2008]
Regulations Shift Focus on Outbound Email Security: The Impact of HIPAA, PCI, PIIG and Other New Government and Industry Guidelines on Email Security Policies
White Paper Read this paper to learn about the impact of relatively new data protection regulations and standards such as the Payment Card Industry (PCI) Data Security Standard (DSS) and the Office of Management and Budget (OMB) Personally Identifiable... [05 Aug 2008]
Using Dynamic Optical Networking for High-Speed Access
White Paper The solution is developed in the context of existing constraints, such as the presence of ring based metropolitan area access and core networks, and Ethernet cards in end hosts. While LAN and wide-area network link capacities keep increasing... [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]
On the Capacity of Optical Networks: A Framework for Comparing Different Transport Architectures
White Paper This comparison is based on a notion of network capacity as the set of exogenous traffic rates that can be stably supported by a network under its operational constraints. This paper compares three optical transport network architectures: Optical... [18 Jul 2008]
A New QoS Routing Framework for Solving MCP
White Paper This paper introduces a new QoS routing heuristic framework, which focuses on how to increase the success ratio for finding a feasible path subject to multiple additive constraints. One purpose of Quality-of-Service (QoS) routing is to develop... [18 Jul 2008]
Non-Adaptive Fault Diagnosis for All-Optical Networks Via Combinatorial Group Testing on Graphs
White Paper This fault diagnosis problem motivates a new technical framework that the paper introduces: group testing with graph-based constraints. This paper considers the fault diagnosis problem in all-optical networks, focusing on probing schemes to detect... [18 Jul 2008]
A Comparison of Multiprotocol Label Switching (MPLS) Traffic-Engineering Initiatives
White Paper This tutorial examines the fundamental changes being made to signaling protocols used to manage data in a large MPLS network and make it possible to determine the best route, given a set of stated bandwidth constraints. [18 Jul 2008]
Optimal Replica Placement in Tree Networks With QoS and Bandwidth Constraints and the Closest Allocation Policy
White Paper The latter problem is investigated using the Closest access policy when adding QoS and bandwidth constraints. This paper deals with the replica placement problem on fully homogeneous tree networks known as the Replica Placement optimization problem. [11 Jul 2008]
Quality of Service Routing in MPLS Networks Using Delay and Bandwidth Constraints
White Paper In the MPLS networks, constraint-based routing computes routes that are subject to constraints such as bandwidth and administrative policy. The proposed algorithm which is a modification of Wang-Crowcroft algorithm, uses both bandwidth and delay... [11 Jul 2008]
Fault Restoration Techniques for MPLS With QoS Constraints
White Paper Using the concept of equivalent bandwidth, an integer linear program is developed that determines a set of backup paths that meets the QoS constraints, and minimizes the total capacity needed. This paper investigates distributed fault restoration... [11 Jul 2008]
Performance Comparison of Ad-Hoc Routing Protocols for Networks With Node Energy Constraints
White Paper A major issue with ad-hoc networks is energy consumption since nodes are usually mobile and battery-operated. This paper compares the performance of ad-hoc routing protocols in a network where each participating mobile node has a given battery life... [11 Jul 2008]
A Reservation Scheme Satisfying Bandwidth QoS Constraints for Ad-Hoc Networks
White Paper Achieving QoS (Quality of Service) in Mobile Ad-hoc NETworks (MANET) has been a research topic in the last years. This paper describes a QoS reservation mechanism for Routing Ad-hoc Networks. The mechanism is targeted for sources requiring a... [11 Jul 2008]
Optimal Routing, Link Scheduling and Power Control in Multi-Hop Wireless Networks
White Paper First it address the problem of finding an optimal link scheduling and power control policy that minimizes the total average transmission power in the wireless multi-hop network, subject to given constraints regarding the minimum average data rate... [11 Jul 2008]
Microsoft Exchange Server 2007 Best Practices Guide
White Paper Along with this critical importance come additional constraints for information technology organizations. Corporate messaging has become mission critical in nearly all organizations. Not only do they have to deal with requests for increased user... [11 Jul 2008]
