One of the current biggest issues in the design and development of the SMPTE ST-2110-based broadcasting facilities is the shortage of Media-over-IP (MoIP) network design engineers who understand both broadcasting and network communications. This is the topic that has been discussed for several years, and I have been working to train engineers over the past years through my experience of the MoIP network design, the situation is getting worse and more serious as the number of the facility developments increases. This presentation can help the target audience, broadcast engineers, who are studying or to study MoIP network technology. When trying to build an actual ST-2110-based network, the first question would be how we design a specific IP network. Unlike peer-to-peer SDI network where we can focus on the physical connection, the data on the MoIP network can be transmitted with inbounded multiple streams in an Ethernet optical cable, and multicast routing settings are required in its network switches. In other words, not only physical design but also logical design becomes more important. The more complicated the system becomes, the more complicated the logical configuration becomes. The network architecture design and its IP addressing could be a key to success of the reliable and scalable network. These technique and idea would be similar as the ones in software engineering, which kind of knowledge and skill set has never been needed by broadcast engineers before. If the SDN controller manages the configuration of its network switches in the near future, it may be possible to build a system without knowing specifically how to implement the logic network design. However, once the network occurs in trouble, engineers who don’t have the network design skill would be at a loss, there should be a risk that we would not be able to analyze to take workarounds. For this reason, I believe it is necessary to study the fundamental skill of such appropriate MoIP network design. At the previous NAB2022 and IBC2022 IPShowcase, I introduced the essential terminologies for configuring network switches that network engineers should know (VLAN, VRF, Multicast routing, IGMP, PIM, OSPF, LAG/LACP etc.), and how to design and verify the logical network. In addition, I shared some information about the actual issues I have faced so far. In this presentation, after summarizing the previous two talks, I will focus on the ‘design’ that engineers should think a little more, such as network architecture, network switch selection, physical connection design, and logical connection design including IP address assignment. I would also like to explain some more tips on how to do the design. In addition, I would like to talk about things to be careful about in the design, and things to think about in the future, such as safety design to prevent unexpected failures and errors.

15. ▪ You can use private IP addresses
→ You better to make an IP addressing rule / guideline for your company or facility
▪ Class A
▪ 10.0.0.0 to 10.255.255.255
▪ Class B
▪ 172.16.0.0 to 172.31.255.255
▪ Class C
▪ 192.168.0.0 to 192.168.255.255
▪ Example
▪ Media Nodes: 10.1.x.y (Amber), 10.2.x.y (Blue), 10.3.x.y’(Control)
▪ Network equipment: 172.21.m.n (Amber), 172.22.m.n (Blue), 172.23.k.l (Control)
▪ x / m / k: for Facility A

Tips for IP Addressing (Cont’d)

16. ▪ Use limited IP address resources efficiently
▪ Use /30 subnet mask if you connect peer to peer
Apr/18/2023 © 2023 Xcelux Design Inc. 16
Tips for IP Addressing (Cont’d)
▪ Example: 10.1.0.0/30 subnet
▪ 10.1.0.0 : Network Address
▪ 10.1.0.1 → you can assign
▪ 10.1.0.2 → you can assign
▪ 10.1.0.3 : Broadcast Address
L2/L3 NW Switch
10.1.0.2
10.1.0.1

17. ▪ Do not assign /30 subnet address too packed
▪ Assume your network spec could be changed
Apr/18/2023 © 2023 Xcelux Design Inc. 17
Tips for IP Addressing (Cont’d)
Reserve an IP address area
assuming in advance that
Equipment A will need 1+
more IP addresses for one
port
Packed
(no reserved area)

18. ▪ Network Architecture: when combining 2+ segments
▪ How to integrate MoIP networks which were designed by different thoughts
▪ IP Address : Multicast NAT? → Increases latency
▪ Network Switch Selection
▪ New switches
▪ Safety design and control
▪ Bandwidth management
▪ Other streams should never make damage for the stream on the air

Other issues

19. ▪ As more MoIP facilities are developed,
there will be a greater shortage of MoIP network engineers
▪ It takes some time to become an MoIP network expert
▪ To be the expert need more software-engineering skill
▪ Sharing tips and case studies is a faster way to be the expert
▪ Let's communicate more among MoIP engineers
▪ See you again at the IBC show in September
