Velocity® Global Bandwidth Management – GBWM

This course is intended for personnel responsible for designing and implementing System Wide Quality of Service (QoS) and Service Level Agreements (SLA) on Velocity networks. The training is designed to provide in-depth theoretical knowledge regarding the functionality of Velocity GBWM and Quality of Service; features which include Velocity Global QoS & Regional Scope QoS by defining the relevant Global level’s Group Service Plan (GSP), terminal level’s Subscriber Service Plan Profile (SSPP) & Subscriber Service Plan Components (SSPC), and Fair Access Policy (FAP). The explanation of concept and usages of Service Area (SA) related to Regional Scopes and Regulatory Area (RA) will be covered.

No previous Quality of Service experience is required to attend the training, as the course starts from the very basics: OSI stack, Ethernet frames, IP packets, TCP segments, packet generation and capturing tools, traffic filtering and of course knowledge on Group QoS (GQoS). The theory is enriched by precise step-by-step hands-on instructions which consist of practical example and exercises. This intensive step-by-step hands-on training, combined with GQoS demonstrations, is designed to reinforce the theoretical portion of the course.

The course, a blended format of lectures, demonstrations and practical exercises, is presented in a clear and technical format, providing each learner with the knowledge required to perform advanced bandwidth management and GQoS configurations on Velocity networks. In addition to the learner instructional manual, handouts are provided, as required, to supplement existing course material and provide additional up-to-date details on latest released software and hardware.

After completing all associated materials, lectures, practical exercises and learner knowledge assessments, a final written exam would be administered at the end of the five-day training session. Once completed, each learner will be provided a certificate of course completion.

This is a five-day training course as mentioned beginning.

The Velocity iDirect Operations and Maintenance (V-iOM) course is a prerequisite to attend the Velocity Global Bandwidth Management (GBWM) course, as the topics covered in the introductory training will be the starting point for the advanced one. In addition to that, a Velocity network operation experience of at least 6 months and familiarity with the Pulse NMS is also required.

A basic user level knowledge of Linux operating system command line interface is advised for this course since the training will intensively involve accessing Linux based servers and remotes. In addition to that, the learner must be comfortable over a Windows operating system and have basic software installation skills, since it will be necessary to deploy the suite of 3^rd party’s applications along with SSH and terminal software on the laptops.

Each registered student must bring a laptop computer running Windows XP/7/10, administrative privileges with the firewall temporarily disabled in order to install the following software during the week: Cisco AnyConnect Secure Mobile Client (for VPN connection), PuTTY, WinSCP, iPerf, WireShark, etc. software utilities.

Upon completion of this course, each learner will be able to:

• Confirm & understand the Velocity networking & its architecture, the infrastructure & system-wide QoS components.
• Identify different protocols, in L2, L3 & L4 OSI-7 model and traffic classification. Utilize the industrial well-known software troubleshooting tools.
• Understand the bandwidth pools, demand and allocation flows and the bandwidth allocation order in Group QoS tree hierarchy structure
• Identify the different QoS parameters: Priority, CIR, Cost & MaxIR under the different QoS algorithms and provides the details explanation on how these QoS parameters work and how they can utilize them.
• Configure the Filter Profiles to the Velocity networks.
• Explain the basic concepts of Global Bandwidth Management (GBWM) applying to Service Providers, Service Based QoS, Service Modes and Service Plan. Understand the Velocity bandwidth allocation characteristics under IP Based or Symbol Based Service Modes of QoS configurations.
• Explain the Service Plan in basic level and QoS configuration about the Group Service Plan (GSP), Subscriber Service Plan Profile (SSPP), Subscriber Service Plan Component (SSPC) & Terminal Service Plan (TSP).
• Learn the Terminal QoS configuration and also perform the QoS tests by the simulated UDP and TCP traffic to his/her owned configured lab’s network.
• Understand thoroughly how to the utilize the QoS parameters associated with the designed QoS algorithms.
• Explain the GBWM, Service Plan & QoS in the more advanced level.
• Explain the bandwidth demand and allocation flows as well as bandwidth allocation calculations from the top level of QoS Enforcer (GQE), NOC/GBWM, to SAS’s, iNet’s and the terminal’s SSPC or Virtual Remotes (VRs).
• Explains the features and functions of the Geographic Scope, Service Area (SA) and Regulatory Area (RA) related to QoS and regulatory limits required by the satellite operators to meet the SLA or countrywide regulatory standards.
• Perform the QoS configuration to the GSP and SSPP, down to the terminal’s SSPC and Virtual Remotes (VRs) and how to test under different scenarios, by the simulated UDP & TCP traffic, the bandwidth allocations can be performed.
• Explain, as the satellite operators or service providers, in the high-level overview of how to deploy and provision their defined service plans and Geographic Scopes to their VNO customers and/or their end customers.
• Perform multicast configuration and troubleshooting procedures.
• Understand the relationship among “Operating MODCOD”, “Throughput” and “Symbol Consumption”.
• Recognize the GSP level MIR/CIR and SSPP/SSPC level MIR/CIR “Scaling” characteristics when downstream ACM MODCOD is changed.
• Summarizes the benefits, configuration guidelines and constraint of using the Upstream A-TDMA.
• Consider the uses of GBWM Fair Access Policy (FAP) as part of the “Service Based QoS” strategies. Understand what are FAP & its implementation policies, what are the choices of FAP options and configurations for satellite operators or service providers.

The training material is focused, in its intent, to prepare each learner with the necessary ability to perform essential job functions when they return to their organization. At the end of the five-day training session, and upon successful completion of all course requirements, (practical and/or written), an online course critique/survey will need to be submitted. Once done, a soft copy of a Certificate of Attendance may be submitted to theacademy@idirect.net for processing.
