Wide Area Network Design: Concepts and Tools for Optimization (The Mo…

Network planning and design is an iterative process, encompassing topological design , network-synthesis , and network-realization , and is aimed at ensuring that a new telecommunications network or service meets the needs of the subscriber and operator. A traditional network planning methodology in the context of business decisions involves five layers of planning, namely:. Each of these layers incorporates plans for different time horizons, i. The Operations and Maintenance layer, however, examines how the network will run on a day-to-day basis. These steps are performed iteratively in parallel with one another.

Whiteboard Series — WAN Edge Network Design


Network planning and design

Jump to navigation. Silver Peak gives enterprises and service providers the flexibility to securely connect their users to their applications via the most cost-effective source of connectivity available. This increases application performance, resulting in enhanced user experience, increased business productivity and reduced costs for IT. The delay caused by backhaul impairs application performance resulting in a poor user experience and lost productivity. An SD-WAN handles traffic based on priority, quality of service and security requirements in accordance with business needs. Sending SaaS and IaaS traffic directly across the internet delivers the best application Quality of Experience for end users. However, not all cloud-bound or web traffic is created equal.

It includes a set of heuristic algorithms for solving the virtual topology design, and the routing and grooming of traffic flows on top of it. In addition, an implementation of the linear programming problem to obtain the optimal solution of the complete design is included for comparison. The input parameters to the planning problem are the network physical topology, the traffic matrix, and technological constraints like the number of transmitters, receivers, optical converters and wavelengths available. The set of heuristic algorithms can be easily extended. A graphical interface is provided to plot the results obtained from different heuristics and compare them with the optimal solution in small-scale topologies.
