Video: Monitoring and Measuring IP Media Networks

nn

The transition from point-to-point SDI based infrastructure to IP essence flows requires a very different approach to fault-finding. Although new IP diagnostic tools are already available on the market, engineers need combined broadcast and IT knowledge to fully understand the flow of video, audio and data across the switching fabric – including packet jitter, latency, and buffer over/underflows causing dropped packets.

In this video Michael Waidson from Tektronix presents methodologies involved in monitoring IP media networks. The following topics are covered:

  • Strategies for choosing IP Address, Port Number and Payload Type for easier identification of the streams
  • Troubleshooting basics (fibres and SFPs types, checking switch ports)
  • PTP synchronisation
  • Checking syntax of decoded streams (Layer 5 RTP, Marker Bit, Payload Type, Sequence Number, Timestamp)
  • Packet transmission (multiple paths, out of order packets in receiver, jitter, PIT Histogram)
  • Timing (reference clock, RTP timestamps, checking PTP lock, PTP and RTP offset, transmission traffic shape models)

Video: TR-1001 Replacing Video By Spreadsheet

Here to kill the idea of SDNs – Spreadsheet Defined Networks – is TR-1001 which defines ways to implement IP-based media facilities avoiding some typical mistakes and easing the support burden.

From the JT-NM (Joint Taskforce – Networked Media), TR-1001 promises to be a very useful document for companies implementing ST-2110 or any video-over-IP network Explaining what’s in it is EEG’s Bill McLaughlin at the VSF’s IP Showcase at NAB.

This isn’t the first time we’ve written about TR-1001 at The Broadcast Knowledge. Previously, Imagine’s John Mailhot has dived in deep as part of a SMPTE standards webcast. Here, Bill takes a lighter approach to get over the main aims of the document and adds details about recent testing which happened across several vendors.

Bill looks at the typical issues that people find when initially implementing a system with ST-2110 devices and summarises the ways in which TR-1001 mitigates these problems. The aim here is to enable, at least in theory, many nodes to be configured in an automatic and self-documenting way.

Bill explains that TR-1001 covers timing, discovery and connection of devices plus some of configuration and monitoring. As we would expect, ST-2110 itself defines the media transport and also some of the timing. Work is still to be done to help TR-1001 address security aspects.

Video: AWS Networking Fundamentals

Networking in the cloud, by rights, should be the same in your office but with it’s a lot easier when you’re led through it. From subnets to VPN’s, this talk from AWS makes sure you can get your VPC (Virtual Private Cloud) talking to other parts of your cloud infrastructure and your office.

Starting with the basics and building up, Perry and Tom take us through the IP address allocation, address choices, firewall configuration, security configuration and then on to Direct Connect, VPNs sharing VPC resources and much more.

From the AWS Summit 2019, this is a great talk for those who know networking well and are new to AWS, as well as those who are comfortable with AWS names, but are a little rusty on the finer points of networking.

Watch now!
