Network Design Requirements

For the Visual Networking Platform

Introduction

The Userful Visual Networking Platform leverages your existing conventional network assets to deliver visual content. This section details how to ensure your network makes full use of Userful functionalities and is configured to allow Userful to function to its full potential.

Userful On-Premise

Network Structure

On-Premise servers actively stream video data to their endpoints. For reliable operation, design requirements can be modified by dividing traffic into separate network segments namely, Layer2 (Zero Client) or Layer 3 (uClient).

Please note only uClient device(s) or a Zero Client device(s) can be connected to the same server at once.

uClients

uClients require access to both the on-premise server and the internet to receive uClient application updates and device firmware updates. It does not need to access the corporate LAN. uClient can operate on a completely isolated network, however, provisions must be taken to distribute application and firmware updates to the devices manually when the server receives updates.

LG WebOS or Android uClient require access to a local server and the internet to receive application and firmware updates. Application updates can be delivered from a local server or manually using a USB key; LG WebOS firmware updates can be delivered from the Internet or installed on the device using a USB key.

Userful uClients can access cloud-connect.userful.com via TCP port 443 and can traverse subnets while remaining connected to the same subnet as the local server. If the entire Userful system is used offline and there are no updates or Internet access, it is recommended to use zero clients.

Firmware updates for the Userful uClient adapter are not yet supported.

Zero Clients

The Zero Client can be hosted on a completely isolated network, with no access to anything other than the Userful server. Zero Client firmware updates are delivered by the server itself, and the Zero Client does not need to be connected to the Internet.

Network Addressing

All client types, right out of the box, will ask for a DHCP lease on the wired interface. Ideally, a DHCP server should be available to distribute the lease. If not, other measures must be taken.

uClients

uClient devices can have their network settings configured on the device itself, using attached or included peripherals.

Zero Clients

If Zero clients do not receive a response to their DHCP request after a few minutes, they will be assigned an IP address of 10. 254.10.10. In this situation, they cannot be addressed by Userful and may assign themselves conflicting IP addresses.

Once the Zero client has an IP address on the same network as the Userful server, you will be able to manage the client and change its IP settings from the Userful Control Center.

Network Capacity

Zero Clients and uClients have different network specifications that must be met for reliable operation.

Userful requires a 10GB Uplink for optimal performance. The number of displays supported are affected by the following factors:

  1. Certain driver limitations may limit the network interface throughput of Zero clients at 2.5Gbps.

  2. Type of content being played on the display screens. Streaming heavy streams of data can reduce the optimal amount of display screens.

Network Firewall

Server Rules

The following Internet destinations should be accessible by the Userful server for complete connectivity and support.

The following local ports must be accessible from the corporate LAN to allow browser-based access and operation of Userful.

These local ports from the corporate LAN on an On-Premise Server are optional.

*Public Computing deployments only.

uClient Rules

The following ports and services must be available between a Userful On-Premise server and endpoints running uClient and between uClient and the Internet for proper operation.

Zero Client Rules

Zero Clients must be placed on a separate network from the Corporate network. They will use these ports and protocols to communicate with the Userful server.

It is strongly recommended to have unrestricted access to this network.

Userful Cloud

Userful uClients are able to sync to Userful Cloud servers without any other local hardware or server. They are synced and managed entirely from the cloud web service, which is hosted by Userful in AWS.

Zero Clients can not be used with the Userful cloud, they can only be paired to a local on-premise server.

Network Structure

uClients connecting to Userful Cloud will download and playback content locally, so are not required to occupy their own separate network. Doing so is still a recommended best practice.

Most uClient devices come with wireless interfaces. These are not supported for On-Premise deployments and are not recommended for Cloud deployments.

Network Addressing

uClient devices come out of the box querying for DHCP on their local wired interfaces. They can be manually locally configured with static IPs.

Network Capacity

uClient downloads content from cloud servers in Userful Manager to internal storage for local playback. There are no specific bandwidth or latency requirements, except that Internet bandwidth is sufficient to deliver large content files, and local communication for synchronization is reliable.

Network Firewall

uClient devices must be able to communicate with the Internet to sync with Userful Manager, and also must be able to communicate with each other across the local network to maintain content synchronization.

Engage CMS IP Address

If your deployment includes the use of the Userful Engage CMS, you will need to ensure that your on-premise servers and/or uClient devices are able to access the EngageIP addresses on the TCP port 443:

  • Files:

    • 205.185.216.10

    • 52.217.39.148

    • 162.243.189.2

  • API

    • 45.55.116.139

    • 134.209.131.177

    • 172.217.2.227
