February 2024

• The Video Mesh platform is now integrated with the ThousandEyes Enterprise agent, enabling you to perform end-to-end monitoring across your hybrid digital ecosystem. This integration equips you with a wide array of network monitoring tests. Issues anywhere in your network infrastructure can be diagnosed with greater precision, improving the efficiency of your deployment.

  For more information on enabling ThousandEyes for your organization and configuring tests, see ThousandEyes Integration with Video Mesh.

• In accordance with the previous announcement regarding Container registry migration to Amazon ECR, we expect to complete the migration by mid-March, 2024. Kindly ensure connectivity to ECR by allowing the URL, "*dkr.ecr.us-east-1.amazonaws.com" in your application firewalls and proxies.

December 2023

Container registry migration from Docker Hub to Amazon ECR

Video mesh container registry that hosts images will be changed from Docker Hub to Amazon ECR. This migration is scheduled to take place in February 2024. We kindly request customers to ensure connectivity to ECR by allowing the URL, "*.amazonaws.com" in their application firewalls and proxies. This step is necessary to prevent any potential issues during upgrades.

August 2023

We've improved versatiltity and functionality of Video Mesh node APIs by adding a whole host of new APIs with varying functions. Admins can now choose between 3 categories of APIs that can aid them in different stages of node deployment. They are as follows:

• VMN Administration APIs

• VMN Network APIs

• VMN Server Certificate APIs

July 2023

Webhooks for Video Mesh Alerts

Video Mesh now supports alerts through Webhooks, enabling organization admins to monitor certain aspects of their deployments effortlessly. They can choose to be notified of events like call overflows and call redirects, minimizing the need to log in to Control Hub for monitoring their deployment.

In this phase, the following event types can be monitored through webhooks:

• Cluster Call Redirects – Calls redirected from a particular cluster.
• Org Call Overflows – Total call overflows to cloud for an organization.

Video Mesh Node APIs

We have introduced a set of APIs that will help organization admins create, update, download, and delete certificates related to Video Mesh Nodes. See Video Mesh Node APIs for more information.

June 2023

We've refined the graphs and charts of the Analytics dashboard to augment the Client Type Inclusion feature.

• You can see cluster-specific data in the Resources tab.

  Select a cluster in any of the donut graphs or charts and then click Apply. This action also filters the data for all other graphs, so you only see the data that's relevant for your selected cluster.

• We've added two new graphs to the Resources tab. They are Total call joins by endpoint type and Total call joins by endpoint type trend. You can select clusters and specific endpoint types, to show only the information you need.

• On the Engagement tab, we've grouped the Call legs by endpoint type graph into the following types:

  • SIP devices
  • Webex App desktop
  • Webex App mobile
  • Webex App VDI
  • Webex devices

May 2023

Web client support

Calls made through web client can now land on Video Mesh nodes, providing your organization with greater versatility in the types of calls supported.

March 2023

New reachability test and improved monitoring tool

We've added a reachability test to the existing set of monitoring tests. The reachability test runs with the media health monitoring tests, both periodically and on-demand. We've also improved the monitoring tool to give more detail in the test results, and updated the overview page to provide simpler, more intuitive access to detailed information.

We've changed the UI path to reach the Video Mesh monitoring tool. You can find the new Video Mesh tab at Troubleshooting > Video Mesh instead of Troubleshooting > Status > Video Mesh as before.

The monitoring tool overview page groups the tests into Signaling, Cascade, and Reachability, helping you to fine-tune your troubleshooting process.

February 2023

Video Mesh developer APIs for troubleshooting & integration with third-party monitoring systems

• In this phase of the Video Mesh Developer APIs, we have introduced enhancements that enable organization admins to take complete control of troubleshooting their Video Mesh Deployments.
• Admins can now trigger various On Demand Troubleshooting tests such as Network, Media Health Monitor and Reachability Tests from the Developer Portal. They can also view detailed results of the tests they triggered, helping them gain deeper insights into the health of their deployment.

November 2022

Cluster renaming in Control Hub

You can now edit the names of your Video Mesh clusters in Control Hub. We've also added Unicode support to the cluster names.

September 2022

Video Mesh Developer APIs

The Video Mesh Developer APIs provide a powerful and flexible way for organization admins to retrieve detailed metrics for monitoring and insightful analytics data of their Video Mesh deployments through the Webex Developer Portal. They can seamlessly integrate their existing monitoring applications with these APIs and automate monitoring of their Video Mesh clusters and nodes. The APIs are available at https://developer.webex.com/docs/api/v1/video-mesh. A sample client is available at https://github.com/CiscoDevNet/video-mesh-api-client.

July 2022

Media Health Monitoring tool change

We have changed the frequency of periodic cluster-wide, cluster-specific, or node-specific tests. These tests ran hourly in previous releases. They now run every 6 hours.

April 2022

Keep your media on Video Mesh for all external Webex meetings

In previous releases, you controlled the use of Video Mesh for meetings only for your internal sites. For meetings that are hosted on external Webex sites, those sites controlled if Video Mesh could cascade to Webex. If an external site didn't allow Video Mesh cascades, your media always used the Webex cloud nodes.

With the Prefer Video Mesh for All External Webex Meetings setting, if your Webex site has available Video Mesh nodes, your media runs through those nodes for meetings on external sites. For details, see https://help.webex.com/en-us/article/nzvixgk/Keep-your-media-on-Video-Mesh-for-all-external-Webex-meetings.

January 2022

Port updates

For an upcoming release in February 2022, Video Mesh requires opening the following port range for Media Cloud Cascades:

These ports are in addition to the existing port 5004. Open the UDP 50,000–53,000 port range in your firewall configuration. You'll see service disruptions if these ports aren't open when the upcoming release goes out.

As listed in Network Requirements for Webex Services, the Expressway already uses this port range for the Webex cloud. So, most deployments don't require any updates to support this new requirement for Video Mesh. But, in deployments with more stringent firewall rules, update your firewall configuration to open these ports for Video Mesh before the February release.

October 2021

Globally Distributed Media

Video Mesh now uses globally distributed media (GDM) capabilities of Webex to achieve better media routing. To achieve optimal connectivity, Webex selects the nearest cloud media node to your enterprise when performing Video Mesh cascades to Webex. Traffic then passes through the Webex backbone to the Webex microservices for the meeting. This routing minimizes latency and keeps most of the traffic on the Webex backbone and off the internet.

August 13, 2021

Private Meetings

The Private Meeting feature enhances the security of your meeting by terminating the media on your premises. When you schedule a private meeting, the media always terminates on the Video Mesh nodes inside your corporate network with no cloud cascade. Unlike normal meetings, if the local nodes are full, the media does not cascade to the Webex cloud.

All participants in a private meeting must belong to your organization. They can join using the Webex App or an authenticated video system. Participants with VPN or MRA access to your network can join a private meeting. But nobody can join a private meeting from outside your network.

See the Private Meetings section in the deployment guide at https://www.cisco.com/go/video-mesh and the Schedule a Webex Private Meeting article.

Access Nodes from Control Hub for Full Administrators

We enhanced Control Hub to enable Full Administrators of your Webex organization to access Video Mesh nodes from Control Hub.

Only a Full Administrator for your Webex organization can use this feature. Other administrators, including Partner and External Full Administrators, don't have the Go To Node option for the Video Mesh resources.

See the Access Overview of Webex Video Mesh Node From Web Interface section in the deployment guide at https://www.cisco.com/go/video-mesh.

DNS Caching

If DNS responses to your Video Mesh nodes regularly take more than 750 ms, you can enable DNS caching. With DNS caching on, the node caches DNS responses locally. Local caching makes requests less likely to cause connectivity alarms, call drops, or call quality issues. DNS caching can also reduce the load on your DNS infrastructure.

DNS caching is currently disabled by default. To turn it on, see the Enable or Disable DNS Caching section in the deployment guide at https://www.cisco.com/go/video-mesh.

Webex Events Support

Webex Video Mesh now supports Webex Events.

Short Video Address Format for Webex Meetings

On WBS39.9 and later sites, users can join meetings using the shorter <meeting_number>@webex.com video address format (instead of <meeting_number>@<site_name>.webex.com). Video Mesh now supports this shorter address format.

The deployment guide at https://www.cisco.com/go/video-mesh has instructions on handling the shorter format when setting up a Video Mesh deployment.

To use the short video address format with an existing Video Mesh deployment, add a route or dial pattern to handle the format. For more details, see the appropriate task that includes "short video address" in the guide, depending on how you configured your call control environment:

• Configure Unified CM Secure TLS SIP Traffic Routing for Webex Video Mesh

• Configure Unified CM TCP SIP Traffic Routing for Webex Video Mesh

• Configure Expressway TCP SIP Traffic Routing for Video Mesh

By default, meeting invitations currently still use the longer format. To change the format for your Webex site, see Display the Short Video Address Format for Webex Meetings and Events.

New Network Interface MTU Configuration Settings in the Video Mesh Node Web Interface

You can now manually set the maximum transmission unit (MTU) size on the internal network interface and the MTU on the external network interface, if enabled.

All Webex Video Mesh nodes have Path MTU (PMTU) discovery that is enabled by default. With PMTU, the node can detect MTU issues and adjust the MTU size automatically. When PMTU fails because of firewall or network issues, the node can have connectivity issues to the cloud because packets larger than the MTU drop. Manually setting a lower MTU size can fix this issue.

You can find the manual MTU settings on the network settings page Advanced tab in the Webex Video Mesh Node web interface. For more information, see the deployment guide at https://www.cisco.com/go/video-mesh.

New VMNLite Deployment Option

Deployments of mainly Webex Teams and cloud-registered endpoints use more switching and fewer transcoding resources than the standard configuration provides. Deploying more, smaller virtual machines on the host optimizes resources for this scenario.

For this reason, we’re introducing a new "VMNLite" option for deploying multiple Webex Video Mesh Nodes to your host server running VMware ESXI or vCenter. VMNLite requires the following specifications for each virtual machine:

• 23 vCPUs for Video Mesh Node

• 20-GB main memory

• 80-GB local hard disk space

With these specifications, you can deploy (or replace a singe existing virtual machine with) multiple instances, depending on the hardware:

Our testing shows a 50% improvement in switched call performance with 3 VMNLite nodes on a single CMS1000 compared to deploying a single virtual machine.

As with the standard configuration, you can't have coresidency with other services on VMNLite virtual machines.

For more information, see the deployment guide at https://www.cisco.com/go/video-mesh. For steps to replace your standard configuration with VMNLite, see the Manage and Troubleshoot Webex Video Mesh chapter.

New Weekly Automatic Software Upgrade Option for Video Mesh Clusters

You can now schedule automatic software upgrades on your Video Mesh clusters to happen on a weekly basis instead of daily (the default). You can postpone an upgrade one time. If you set a weekly schedule, postponing means that the upgrade occurs during the following week's upgrade window.

You can set the upgrade schedule while registering a new cluster, or modify the schedule of an existing cluster. For more information, see the Video Mesh documentation at https://www.cisco.com/go/video-mesh.

External Network Interface, Routing Rules, Container Network options in the Video Mesh Node Web Interface

The Video Mesh web interface contains more new features to make handling network changes easier. You can enable the external interface in a dual network interface (NIC) deployment from the web interface. You can then fine tune the routing for Video Mesh nodes by adding user-defined route rules for external and internal interfaces. And you can change the container bridge IP address and subnet.

For more information about how to access the updates to the web interface, see the Manage and Troubleshoot Webex Video Mesh chapter in the deployment guide at https://www.cisco.com/go/video-mesh.

Cisco Webex Teams EMEAR Data Residency Support

Organizations in the Cisco Webex Teams European data residency region. can now use Video Mesh. This support includes both newly created phase 2 EMEAR organizations and existing phase 1 EMEAR organizations.

For more information, see Data Residency in Cisco Webex Teams.

Quality of Service (QoS) Enhancements for Video Mesh

Video Mesh nodes now conform to recommended quality of service (QoS) best practices by enabling port ranges that allow you to differentiate audio and video streams in all flows to and from the Video Mesh nodes. This change will let you create QoS policies and effectively remark traffic to and from the Video Mesh Nodes.

Accompanying these port changes are QoS changes. Video Mesh nodes automatically mark media traffic from SIP registered endpoints (on-premises Unified CM or VCS Expressway registered) for both audio (EF) and video (AF41) separately with appropriate class of service and use well-known port ranges for specific media types.

The source traffic from the on-premises registered endpoints is always determined by the configuration on the call control (Unified CM or VCS Expressway).

For more information, see the QoS table at Ports and Protocols Used by Webex Video Mesh and the steps to enable or disable QoS in the Video Mesh Deployment Task Flow in the Deployment Guide for Cisco Webex Video Mesh ( https://www.cisco.com/go/video-mesh).

Support for Cisco WebEx and Cisco Spark Meetings, Port Changes, and OVA Update

Cisco Spark Hybrid Media Service now supports on-premises SIP registered endpoints joining Cisco WebEx meetings and Cisco Spark meetings. The service also includes new usage and adoption reports in Control Hub. You must make sure your WebEx site is on the Cisco WebEx video platform version 2.0 to take full advantage of Hybrid Media Service. (You can verify that your WebEx site is on video platform version 2.0 if it has the Media Resource Type list available in the Cloud Collaboration Meeting Room site options.)

Port Changes

• The Hybrid Media Service now requires a new destination port (5006).

• TCP/UDP Port 33434 is no longer supported by the service.

For a full list, see " Ports and Protocols Used by Hybrid Media Service" in the Deployment Guide for Cisco Spark Hybrid Media Service.

OVA Update

The service requires you to download and install the latest OVA update on your Hybrid Media Nodes. To download the latest OVA, from the customer view in https://admin.ciscospark.com, go to Services > Hybrid Media > Set Up > Settings.

Upgrade each Hybrid Media Node in your cluster by doing the following steps:

1. Move the node to maintenance mode. See Move a Hybrid Service Node in to Maintenance Mode.

2. Deregister the node. See " Deregister Hybrid Media Node" in the Deployment Guide for Cisco Spark Hybrid Media Service.

3. Delete the Hybrid Media Node VM from the VMware vSphere client or from vCenter.

4. Install the new Hybrid Media Service OVA and software, set the newtork configuration, and reregister the Hybrid Media Node to the Cisco Collaboration Cloud. See " Deploy Hybrid Media Service" in the Deployment Guide for Cisco Spark Hybrid Media Service.

5. Move the node out of maintenance mode. See Move a Hybrid Service Node in to Maintenance Mode.
