Understanding Networking Basics

Jitter causes
To better understand jitter, here are basic networking terms you must know:

Data Packets
Data packets are data kuwait telegram units grouped into packets that travel along a network path. Simply put, data packets are a part of Internet Protocol (IP) transmissions for data on different networks. They offer speed and reliability, thus, forming the backbone of reliable internet communications.

Data packet has a header (with instructions), payload (actual data), and the trailer(error checking/pinpoints the end). When data packets fail to reach their destinations, you’ll experience jitter.

Also, connecting multiple computers on a network takes up a lot of data/bandwidth. In turn, this slows down everybody on the entire network.

VoIP
VoIP technology converts the voice signal into digital signals or data packets that travel through the internet to a receiver. Voice packets require prioritization. The lack of voice packet prioritization is the primary cause of VoIP jitter.

Millions of voice packets are transmitted back and forth every second. Undoubtedly, the massive data takes a toll on network resources, resulting in delays. In VoIP, a delay is noticed when the voice arrives in disorganized packets. Such voices are distorted and out of sequence.

Network Jitter: What Are the Typical Causes?
When you understand the causes of jitter, you are in a better position to effectively handle it as and when it occurs. Here are some typical causes:

Network Congestion
Network congestion occurs when many devices use the same network, causing queueing. This leads to less than enough bandwidth, slowing the connection. In turn, it causes jitter and other call quality issues.

Poor Hardware Performance
Outdated equipment and software are another cause of jitter. Not all equipment and software can handle the latest inventions in communication – for instance, HD videos. If your communication system is dated, it could cause a jitter. So, ensure all cables, routers, and switches are modern.
