White Paper Asynchronous Transfer Mode (ATM) is the new generation of computer and communication networks that are being deployed throughout the telecommunication industry as well as in campus backbones. ATM technology distinguishes itself from the previous... [18 Jul 2008]
Insecurity in ATM-Based Passive Optical Networks
White Paper This paper considers the security of an ITU standard for ATM-based passive optical networks. First, it shows that the standard's encryption algorithm, called churning, has an effective 8-bit key length and thus is trivial to break with exhaustive... [18 Jul 2008]
A Modular Gigabit Ethernet Backbone for NEPTUNE and Other Ocean Observatories
White Paper Recently, Gigabit Ethernet (GbE) technology has successfully competed with SONET and other legacy alternatives such as ATM and Frame Relay for Metropolitan Area Network (MAN) and Wide Area Network (WAN) implementations. [18 Jul 2008]
Advanced QoS White Paper
White Paper An Ethernet service that is becoming more attractive to end-users is the Virtual Private LAN Service (VPLS) or Provider Provisioned Virtual Private Network (PPVPN).VPLS enables Service Providers (SPs) to deliver Virtual Private Network (VPN... [18 Jul 2008]
An Investigation of MPLS Traffic Engineering Capabilities Using CR-LDP
White Paper Multi Protocol Label Switching (MPLS) was initially proposed to overcome the bottleneck of IP routing over ATM while retaining the efficiency of ATM's label swapping and forwarding abilities. Now with the advent of gigabit routers the issue of... [18 Jul 2008]
On QoS Management of H/2 Bearer Service for 3G Telecommunication Systems
White Paper ATM, IP). The paper proposes a mechanism on how to enhance the QoS capability handling of H/2 bearer for IP services, as well as provide the means to interconnect to oncoming 3G core networks. 3G telecommunication systems encompass a high-speed... [18 Jul 2008]
Bandwidth Measurement in xDSL Networks
White Paper A stepwise algorithm is designed to minimize the effect of ATM traffic shaping for ABR and UBR service classes in xDSL deployments on the bandwidth measurements. This paper presents a design and implementation of a scheme for accurate measurement... [11 Jul 2008]
A Column-Generation and Branch-and-Cut Approach to the Bandwidth-Packing Problem
White Paper These problems occur within ATM technology and when video data is routed. The bandwidth-packing problem is a combinatorial optimization problem arising from telecommunication networks where demand exceeds capacity and where point-to-point calls... [11 Jul 2008]
Nott Company Gets Flexible With MPLS
White Paper The company wanted to provide multiple locations with reliable and cost-effective, high-speed network access and ATM over DSL network which lacked the flexibility to accommodate growth. Nott Company deployed New Edge Networks for its solution and... [11 Jul 2008]
Quality of Service Routing in MPLS Networks Using Delay and Bandwidth Constraints
White Paper ATM and Frame Relay) with the routing of layer 3 (e.g. In the MPLS networks, constraint-based routing computes routes that are subject to constraints such as bandwidth and administrative policy. This paper proposes a new constraint based routing... [11 Jul 2008]
Restoration Algorithms for Virtual Private Networks in the Hose Model
White Paper The endpoints of a VPN are connected using abstractions such as Virtual Channels (VCs) of ATM or Label Switching Paths (LSPs) of MPLS technologies. A Virtual Private Network (VPN) aims to emulate the services provided by a private network over the... [11 Jul 2008]
An On-Line Managed Bandwidth Service for ATM Networks
White Paper The work presented here attempts to face from a practical point of view the problem of bandwidth management in ATM networks, especially in cases where the available resources have to be shared among many users with conflicting needs. [10 Jul 2008]
Transitioning From IP-over-LANE/ATM to IP/MPLS Networks
White Paper This paper addresses the limitations of IP-over-LANE/ATM networks and offers a viable IP/MPLS network alternative that supports voice, video, and data services. It also describes an example transition plan for migrating away from an IP-over-LANE... [10 Jul 2008]
Removing Cell Demultiplexing Performance Bottleneck in ATM Pseudo Wire Emulation Over MPLS Networks
White Paper Cell multiplexing is highly desirable to achieve increased transport efficiency in Asynchronous Transfer Mode (ATM) pseudo wire emulation over a MultiProtocol Label Switching (MPLS) network. Supporting cell multiplexing, however, can create... [10 Jul 2008]
Design and Implementation of a Full Bandwidth ATM Firewall
White Paper However, access-control tools such as firewalls when used with ATM networks can destroy these properties. This paper describes a new architecture providing a high speed access-control service for ATM and IP over ATM networks. [10 Jul 2008]
