Interpreting network quality test results

Follow

Firewall Test - UDP and TCP Ports

Pass? This means that you have the required ports open for Talkdesk technology. You are allowing outbound communication through ports:

UDP 10000-60000

TCP 443,80

Fail? This means that you have ports blocked in the required range of Talkdesk technology. 

You may have a block on your computer or Network firewall. 

What are these ports?

UDP Ports 10000-60000 are used to transport the audio of the call itself. 

TCP Ports 443, 80 are HTTPS (443) and HTTP (80). These ports control the application and monitor the calls and the flow. TCP ports are the pipes and UDP ports are the water the pipes carry. 

 

TCP Speed Test - TCP Test 

Pass? This means that your setup can handle the traffic that this many users will produce over TCP (The controlling packets.) Each test, with a different number of users, will simulate different amounts of traffic. 

Fail? When you fail this test, it's indicating that you may not have sufficient bandwidth for this amount of traffic or you may have a QOS or Proxy server controlling too much of your traffic. You need to pull your bandwidth logs and investigate if your bandwidth is adequate. Double check that your bandwidth is not peaking.

 

Upload VS Download

When you fail a download section of TCP, this means the information is not coming into your network.

When you fail Upload, this means that you are unable to send out at a fast enough speed. 

 

UDP Speed Test - Audio Stream Test

Pass? When you pass this test, you network and ISP are strong enough to move the amount of UDP (Voice Packets) that you need for the call audio itself. If you wish to increase your user count, make sure you run the tests beforehand. 

Fail? When you fail this test, either your ISP or your Network cannot handle the load of UDP (Voice Packets) that are traveling between the agents and the server. When this happens, the three likely causes are Bandwidth, QOS systems (Quality of service software or hardware) or Burst Limiting from the ISP level.

 

TCP Latency & Jitter - Latency and Jitter

Pass? When you pass this test, it means you have a clear connection between the Agent and the server for controlling TCP packets.

Fail? When you fail this test, you want to look for QOS systems or Proxy servers. You may also need to contact your ISP and talk about other speed options. 

Latency - Is how long it takes for a packet to leave one location and arrive at another location

Jitter - Is the accuracy of the packets showing up in the right order at the destination.

 

UDP Latency & Jitter - UDP - Latency and Jitter

Pass? When you pass this test, it means you have a clear connection between the Agent and the server for the voice packets themselves.

Fail? When you fail this test, you want to look for QOS systems or Proxy servers. You may also need to contact your ISP and talk about other speed options. This is showing that the Audio UDP is not making it in time or is arriving out of order. This is indicating that the UDP packets are all taking different routes to the destination.

Latency - Is how long it takes for a packet to leave one location and arrive at another location

Jitter - Is the accuracy of the packets showing up in the right order at the destination.
