NAB2024 IPShowcase: Mastering the Basics of Media-over-IP Network Design -- Road to Public Access of Practical Training Materials --

I have been actively engaged in MoIP (Media over Internet Protocol) facility network design and the development of MoIP network training materials for several years. Recently, there has been a notable increase in the number of MoIP facility designs in Japan, signaling a growing need for the continuous education and development of engineers involved in MoIP infrastructure. Particularly, insights and tips derived from practical designs are expected to be invaluable for future real-world implementations. In light of this, the presenter has leveraged their experience to construct training materials, incorporating practical content, utilizing actual network switches, and focusing on the design, implementation, and verification of both the media plane and control plane networks.

This presentation shows you some of the contents of these training materials and share tips on how to effectively nurture engineers based on past experiences. The journey begins with the fundamentals of Ethernet/IP protocols and progresses through individual themes such as L2/VLAN, PTP, L3/VRF, Unicast Routing/OSPF, Multicast Routing/IGMP/PIM, MoIP design methodology, IP addressing, and Verification/Debugging, and more. Each topic involves hands-on learning using real equipment including network switchers. The final challenge involves designing, implementing, and validating a network from scratch.

There is a vision to make these materials publicly accessible, allowing anyone interested to benefit from them. The objective is to contribute to the broader community of network engineers and enthusiasts by providing a resource that not only imparts theoretical knowledge but also offers practical, real-world application. By starting with the basics and progressively delving into advanced concepts, this training series seeks to empower individuals to confidently tackle the challenges associated with MoIP network design.

The goal is to create engineering resources that fosters a deeper understanding of MoIP networks and facilitates the development of skilled professionals in this rapidly evolving field. The commitment to openness and knowledge sharing underscores my dedication to advancing the collective expertise within the MoIP community, fostering innovation, and preparing engineers for the dynamic landscape of modern network design.

8. The design of the media plane of MoIP network using PPM-SSM multicast
routing is different from that of common Ethernet/IP based network of IT
infrastructure
Less information about building MoIP network on the internet
The number of MoIP facilities is increasing, but the number of MoIP
network engineers is not increasing
The shortage of MoIP network design engineers has been predicted for
several years

Best for the Broadcast Engineers
who can communicate with customers in broadcasting production arena
who can understand the current systems and basic terminology for broadcast production
The technical terms and design constraints used in broadcast production are unique
It’s not easy to understand them for IT infrastructure network engineers
who is young and has basic computer science knowledge
who is proactive about learning new things

Design  Implementation  Verification
Design is the most important
Assume agile development rather than
waterfall
First spec is not fixed yet
Impossible to predict 100% future problems
by understanding the specifications of all
devices
Assume the spec will be changed when
fixing issues

25. https://en.wikipedia.org/wiki/Open_Shortest_Path_First
It is one of routing protocols for IP networks
It gathers link state information from available routers and constructs a topology map
of the network
You don’t need to make a routing table manually, OSFP does automatically
But you have to consider how a routing table changes when one of switches
accidentally stops
