Telecom Traffic Engineering Training
Telecom Traffic Engineering Training Bootcamp. What will you learn at the TONEX Traffic Engineering Training Boot Camp?
This Innovative Traffic Engineering Training Bootcamp provides a thorough coverage of the principles behind Traffic Engineering for voice, data, video and next generation networks including IP, VoIP, International Voice and Telephony, LTE, LTE Advanced, Voice over LTE (VoLTE), Voice of 5G NR (VoNR), MPLS, GMPLS, virtualized networks, SDN./NFV and other types of networks.
Telecom Traffic Engineering Training is a hands-on class with many problem solving scenarios. We also teach you how to work with QoS, performance KPIs and SLA. Using real-life examples and interactive exercises, we teach practical ways to maintain your valuable customer base, win repeat business, and measure your organization’s ability to meet customer expectations.
TONEX Traffic Engineering Training Boot Camps is an intensive learning experience that cover the essential elements of Traffic Engineering applied to traditional PSTN, Wireless, Mobile and Cellular Networks, Packet Switching, IP and MPLS, Carrier Ethernet, IMS, legacy GSM/GPRS/EDGE/CDMA/UMTS/HSPA/HSPA+, LTE, LTE Advance, LTE-Advance Pro, 5G, SATCOM, VSAT,and other networks and systems.
Traffic Engineering Training Bootcamp is ideal for busy professionals who want to stay current in the traffic engineering field but have limited time to be away from the office.
The objective of traffic engineering (TE) in telecommunication including legacy PSTN, Packet Switching, IP, MPLS , Mobile networks, Satellite Networks is to maximize the profit, i.e. the difference between revenue from user charges and the total network cost. Service guarantees, Resource management policy and Traffic models are discussed.
The constraints of TE include requirements on service performance: Quality of Service (QoS), Quality of Experience (QoE) and Grade of Service (GoS). TE relies on a relationship between models including traffic models, network models, and performance models.
Traffic Engineering involves capacity planning, capacity management and traffic management. Capacity management can include capacity planning, routing control, and resource management. Traffic management includes traffic control functions, traffic shaping, traffic grooming, traffic policy, traffic conditioning, queue management, scheduling, and other functions that regulate traffic flow through the network or that arbitrate access to network resources.
Tradeoff between effectiveness and simplicity TE is concerned with finding an efficient tradeoff between effectiveness (in terms of proximity to optimality) and simplicity (in terms of time and space complexity) for the TE solution.
A highly effective TE solution is desired since it means that fewer call requests needs to be rejected leading to increased revenue. Moreover, expansion of the network capacity is driven by the increase in network demand.
An effective TE solution allows longer time periods between capacity upgrades which means longer time periods for the depreciation of the capital expenditures.
