Packet loss rate is one of the important indicators to measure the quality of network connection. It represents the proportion of packets lost during data transmission, usually expressed as a percentage. For servers located in Hong Kong, the normal level of packet loss can be affected by a variety of factors, including network load, network topology, server location, and data center management and hardware equipment.

　　What is packet loss rate?

　　In network communication, data is divided into small packets and transmitted over the Internet to the destination. Each data packet carries a portion of information, such as text, images, or sounds. However, due to various factors in the network, sometimes these data packets may be lost during transmission, which creates a packet loss rate. Packet loss rate is usually expressed as a percentage and tells us how many packets were lost during transmission.

　　Normal packet loss rate range:

　　Normal packet loss rate ranges can vary depending on network type and usage. Here are some general guidelines:

　　Local network (LAN): Within the LAN, the packet loss rate should usually be close to zero, that is, less than 1%. Within a LAN, network load is usually low and connections between network devices are very stable.

　　Wide Area Network (WAN): On a WAN, such as when connecting networks in different cities or countries, the packet loss rate may be slightly higher, but it should still generally remain below 1%. A high-quality WAN connection should minimize packet loss to provide smooth communication.

　　Internet: On the Internet, packet loss rates can be higher because data needs to travel through multiple routers and nodes. Under normal circumstances, the Internet packet loss rate is usually between 1% and 5%. However, a high-quality Internet connection usually strives to reduce packet loss to provide better service.

　　Special applications: For some special applications, such as real-time audio and video communication (such as Skype, Zoom) or online games, lower packet loss rate is crucial, usually requiring less than 1% to ensure a smooth experience.

　　Reasons for packet loss rate:

　　Network congestion: When a network is overloaded, packets may be lost because routers and switches cannot handle all incoming packets.

　　Network failure: Network hardware or connection failure may cause packet loss.

　　Delay and delay: Data packets need to go through different routers and nodes during transmission. Delay may cause the data packet to expire or no longer be valid when it reaches the destination.

　　Natural factors: Natural factors such as weather and earthquakes may cause network connection interruption and data packet loss.

　　How to reduce packet loss rate:

　　Increase network bandwidth: Increasing network bandwidth can reduce network congestion, thereby reducing packet loss rate.

　　Optimizing routing and network topology: Optimizing network routing and topology can improve the transmission efficiency of data packets.

　　Use Quality of Service (QoS): Using QoS technology can allocate more bandwidth to critical applications, thereby reducing packet loss rates.

　　Use redundant connections: Multiple network connections can provide redundancy to ensure that even if one connection fails, data can still be transferred.

　　In summary, the normal level of packet loss depends on the type and use of the network. When choosing a cloud server or hosting service, it is recommended to understand the quality commitment of the network service provider and ensure that they provide high-quality connections with low packet loss rates. If you are experiencing excessive packet loss rates when using a particular service, you may consider contacting your service provider for a solution.
