RSS treeThe 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]
A Scalable Distributed QoS Multicast Routing Protocol
White Paper This paper presents a new scalable QoS Multicast Routing protocol (SoMR) that has very small communication overhead and requires no state outside the multicast tree. Many Internet multicast applications such as teleconferencing and remote diagnosis... [18 Jul 2008]
Whitehall IT to be carbon neutral by 2020
News Any remaining departmental IT emissions will be offset - via carbon offset tree planting schemes and the like, according to a Cabinet Office spokesman. The government has announced plans to make Whitehall's computer systems wholly carbon neutral by... [17 Jul 2008]
Sink Tree-Based Bandwidth Allocation for Scalable QoS Flow Set-Up
White Paper This paper explores the possibility of a scalable QoS flow set-up using a sink-tree paradigm. The paradigm constructs a sink tree at each egress edge router using network topology and bandwidth information provided by a QoS extended version of Open... [11 Jul 2008]
Optimal Replica Placement in Tree Networks With QoS and Bandwidth Constraints and the Closest Allocation Policy
White Paper This paper deals with the replica placement problem on fully homogeneous tree networks known as the Replica Placement optimization problem. The client requests are known beforehand, while the number and location of the servers are to be determined. [11 Jul 2008]
Topological Design of Multiple VPNs Over MPLS Network
White Paper The use of sink-tree (multipoint-to-point) routing paths in a MPLS network makes the VPN design problem different from traditional design approaches where a full-mesh of point-to-point paths often is the choice. [11 Jul 2008]
Algorithms for Provisioning Virtual Private Networks in the Hose Model
White Paper It connects VPN endpoints using a tree structure and this algorithms attempt to optimize the total bandwidth reserved on edges of the VPN tree. The paper shows that even for the simple scenario in which network links are assumed to have infinite... [11 Jul 2008]
AQoSM: Scalable QoS Multicast Provisioning in Diff-Serv Networks
White Paper The key idea of AQoSM is to separate the concept of groups from the concept of distribution tree by "Mapping" many groups to one distribution tree. In this way, multicast groups can now be routed and rerouted very quickly by assigning different... [11 Jul 2008]
Design and Scalability of NLS, a Scalable Naming and Location Service
White Paper NLS is based on a dynamically configured, distributed search tree, with a fat-tree based topology at the global level and spanning trees at the local level. This paper sketches the design, and presents a scalability analysis and evaluation of NLS... [11 Jul 2008]
Aggregated Multicast for Scalable QoS Multicast Provisioning
White Paper In this approach, multiple groups are forced to share a single delivery tree. IP multicast suffers from scalability problem with the number of concurrently active multicast groups, while scalability of QoS multicast is even further from being solved. [11 Jul 2008]
Edge Router Multicasting With MPLS Traffic Engineering
White Paper This paper have proposed an Edge Router Multicasting (ERM) scheme by limiting branching point of multicast delivery tree to only the edges of MPLS domains. Explicit routing in MPLS is utilized in traffic engineering to maximize the operational... [11 Jul 2008]
Optimal Bandwidth Reservation in Hose-Model VPNs With Multi-Path Routing
White Paper While previous work has considered tree routing and single-path routing between the VPN endpoints, it is demonstrated that the use of multipath routing offers significant advantages. A Virtual Private Network (VPN) provides private network... [11 Jul 2008]
A Scalable Overlay Multicast Architecture for Large-Scale Applications
White Paper It also alleviates the forwarding state scalability problem and simplifies multicast tree construction and maintenance when there are large numbers of groups ongoing in the networks. This paper proposes a Two-tier Overlay Multicast Architecture... [11 Jul 2008]
A Software Fault Tree Approach to Requirements Analysis of an Intrusion Detection System
White Paper The software fault tree approach supports requirements evolution as new intrusions are identified as well as prioritized, incremental development of the distributed IDS. The use of software fault trees for requirements identification and analysis... [10 Jul 2008]
Decision Tree Classifier for Network Intrusion Detection With GA-Based Feature Selection
White Paper This paper use a genetic algorithm to select a subset of input features for decision tree classifiers, with a goal of increasing the detection rate and decreasing the false alarm rate in network intrusion detection. [10 Jul 2008]
