NSP Packet Optimization

Course number: OS00106-W
Course duration: 2 hours
Price: €200

Course overview

This self-paced e-learning course explores how the NSP’s resource controller acts as a centralized online computation engine providing intelligent IP/MPLS network control capabilities so that operators can rapidly adapt to changing demand and traffic patterns.  Learn how to configure Path Computation Element Protocol (PCEP), enabling the NSP as a Path Computation Element (PCE) containing all the logic to calculate paths through the network.  Discover the many functionalities of NSP’s Path Control Function, including how to apply objectives and constraints to the LSPs in your network.  See how the Path Control Function performs use cases such as implementing path profile override and activating maintenance mode for link sets.  Also, learn how the live network can be imported into the Path Simulation Function to perform What-If Analysis.
