A Survivable Network Design with Capacity Sharing between IP Service and Wavelength Service

Survivable IP network design with OSPF routing

Internet protocol (IP) traffic follows rules established by routing protocols. Shortest path based protocols, such as Open Shortest Path First (OSPF), direct traffic based on arc weights assigned by the network operator. Each router computes shortest paths and creates destination tables used for routing flow on the shortest paths. If a router has multiple outgoing links on shortest paths to a g...

Service Network Design of Bike Sharing Systems

Bike sharing has recently enabled sustainable means of shared mobility through automated rental stations in metropolitan areas. Spatio-temporal variation of bike rentals leads to imbalances in the distribution of bikes causing full or empty stations in the course of a day. Ensuring the reliable provision of bikes and bike racks is crucial for the viability of these systems. This paper presents ...

Service Network Design of Bike Sharing Systems with Resource Constraints

Survivable composite-link IP network design with OSPF routing

OSPF, or Open Shortest Path First, is a commonly used interior gateway protocol. An integer weight is assigned to each arc and the entire network topology and arc weights are known to each router. Each router computes a graph of shortest weight paths from itself to every other router in the network. Traffic is routed on the shortest weight paths. All traffic leaving router s with destination ro...

Routing optimization and capacity assignment in multi-service IP networks

This dissertation investigates routing optimization and capacity assignment in IP networks with multiple services. Both are key processes of traffic engineering and network planning, needed for cost-efficient, quality of service (QoS) aware operation of IP networks. Routing optimization provides a means to balance the traffic load in the network with the goal to improve quality of service. The ...
