Differentiated Quality-of-Protection Provisioning in Optical/MPLS Networks
White Paper This paper investigates the problem of dynamic survivable lightpath provisioning against single node/link failures in optical mesh networks employing wavelength-division multiplexing (WDM). This paper present a new approach to provisioning... [11 Jul 2008]
Network Protection Design for MPLS Networks
White Paper This paper considers the problem of designing partially and fully survivable explicit label switched paths for MPLS networks. These problems are model as Mixed Integer Linear Programs. Furthermore, it presents a survivability assessment of the models. [11 Jul 2008]
Capacity Planning of Survivable MPLS Networks Supporting DiffServ
White Paper This paper studies the issue of capacity planning for survivable MPLS networks providing DiffServ EF and BE traffic classes. The problem is formulated as an optimization problem, where the routes are jointly selected for edge to edge EF and BE user... [11 Jul 2008]
Survivable Routing of Logical Topologies in WDM Networks
White Paper We prove necessary and sufficient conditions for a routing to be survivable and use this condition to formulate the problem as an Integer We call such a routing survivable and develop algorithms for survivable routing of a logical topology. [03 Jul 2008]
Cisco Helps IBM Espana Turn on Capabilities on Budget and On Demand Business
White Paper Small branch offices were provided with Cisco 7940 IP phones, Cisco Catalyst 4500 Series switches and Cisco 1760 routers with Cisco Survivable Remote Site Telephony (SRST). The problem was finding ways to best deliver high-quality corporate level... [03 Jul 2008]
Approximating Optimal Spare Capacity Allocation by Successive Survivable Routing
White Paper In the spare capacity allocation problem one seeks to determine where to place spare capacity in the network and how much spare capacity must be allocated to guarantee seamless communications services survivable to a set of failure scenarios (e.g... [03 Jul 2008]
On Survivable Access Network Design: Complexity and Algorithms
White Paper New graph theory problems naturally arise from such features of access network models, different from those targeted towards survivable backbone (mesh) networks. This paper models the important problem of provisioning survivability to an existing... [11 Jan 2008]
Survivable Network Design With Degree or Order Constraints
The paper first considers the SURVIVABLE NETWORK DESIGN problem with degree constraints on vertices: the objective is to find a minimum cost subgraph satisfying certain connectivity requirements as well as degree upper bounds on the vertices. [09 Jan 2008]
Single-Layer Cuts for Multi-Layer Network Design Problems
The goal is to find a minimum cost installation of link and node hardware of both network layers such that traffic demands can be realized via grooming and a survivable routing. The paper studies a planning problem arising in SDH/WDM multi-layer... [09 Jan 2008]
Survivable Composite-Link IP Network Design With OSPF Routing
Given a network topology, a set of link types to be deployed, each having a different capacity, and predicted traffic demands, the problem considered in this paper is to find a set of OSPF weights that minimizes network cost subject to single arc... [09 Jan 2008]

Interference-Aware Topology Control and QoS Routing in Multi-Channel Wireless Mesh Networks
White Paper Based on this concept, it formally defines and presents an effective heuristic for the minimum INterference Survivable Topology Control (INSTC) problem which seeks a channel assignment for the given network such that the induced network topology... [19 May 2006]
Survivable Remote Site Telephony for Cisco IT Operations Command Center
White Paper Survivable Remote Site Telephony (SRST), a feature of Cisco IOS, provided that backup capability. With fewer than half a dozen people working around the clock, the IT Operations Command Center (OCC) shoulders a huge responsibility - facilitating... [03 May 2006]
