What is the difference between TCP and UDP proxy

Proxy protocols facilitate communication between a client device and a proxy server. These protocols are essential for caching resources, concealing IP addresses, and filtering content. Proxy servers commonly handle UDP (User Datagram Protocol) and TCP (Transmission Control Protocol), the two primary protocols for network data exchange, each with distinct characteristics. Proxies can be transparent, operating without the client's awareness, or explicit, requiring deliberate configuration by the client via a third-party provider.

In some cases, proxy servers simultaneously support both TCP and UDP to ensure a secure and anonymous connection for various traffic types. The choice between these connection methods typically hinges on the specific task requirements, desired reliability, and the nature of the data being transmitted.

What is a UDP proxy

This technology directs and processes user traffic via a proxy server. Unlike TCP, its primary advantage is that it initiates operation without first establishing a connection or verifying connection errors. UDP-supporting proxy servers are ideal for tasks where low latency takes precedence over assured data delivery. Applications like video streaming, VoIP communications, and online gaming, which are sensitive to even minimal delays, benefit from this approach.


  • Suitable for a variety of applications, including video streaming, online gaming, and DNS queries.
  • Distributes load across different servers, enhancing system performance and reliability.


  • UDP proxies do not guarantee data delivery, posing issues for applications sensitive to packet loss, such as file transfers or email services.
  • Managing UDP connections is more complex than TCP, necessitating intricate configurations and continuous network monitoring.

An HTTP UDP proxy is commonly utilized to sustain a stable, low-latency connection between clients and servers. This technology excels in optimizing and accelerating DNS queries, significantly enhancing website access performance. Additionally, SOCKS-UDP-Proxies are available for anonymizing UDP traffic. These proxies not only help in circumventing censorship but also bolster security and privacy during network activities.

Due to the complex nature of the User Datagram Protocol (UDP), working with it typically requires specialized knowledge. However, clients have the option to acquire pre-configured packages for interacting with the protocol. Providers, well-versed in UDP, often undertake the necessary setup and debugging of the proxy connection beforehand.

What is a TCP proxy

A TCP proxy is a server that processes and redirects TCP (Transmission Control Protocol) connections between a user's device and remote servers.

Key advantages of a TCP proxy:

  • Ensures reliable and stable connections between clients and servers, with guaranteed data packet delivery.
  • Versatile in application, supporting a wide array of TCP-based software including web browsers, email clients, FTP, SSH, and others.
  • Additionally, similar to UDP, a TCP proxy can distribute the load across multiple servers, enhancing connection performance.

Disadvantages of TCP proxy:

  • Incompatibility with applications that use UDP or other protocols requiring less stringent connection protocols.
  • Higher resource consumption, as TCP proxies need to monitor and manage connections, necessitating greater computational and network resources.

TCP primarily relies on designated ports to route traffic from various clients to different servers, guided by specific rules. This protocol ensures thorough monitoring of each connection, facilitating a high-quality interaction between the client and the server.

A TCP connection is instrumental in web content filtering and controlling access to network resources. It is adept at anonymizing clients and concealing their actual IP addresses during interactions with external servers. This connection type is frequently used by VPNs and proxy servers to establish secure and stable connections over unsecured networks like public Wi-Fi.

Difference between UDP and TCP proxies

The article discusses two primary protocols for data transmission in computer networks, both crucial for facilitating interaction between PCs and other devices across local and global networks. Understanding the significant differences between TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) is essential before selecting a working protocol or a proxy based on either. Having explored what TCP and UDP proxies are, we will now delineate their differences in detail.

Connection establishment

TCP ensures a stable internet connection before initiating data transmission. It commences the exchange of information packets only after successfully establishing a connection between the source and destination addresses. In contrast, UDP bypasses preliminary checks and transmits data immediately upon request, leading to potential data loss.

Guaranteed transmission

As previously mentioned, UDP does not perform checks on the connection, nor does it monitor the quality of information reception and transmission. Consequently, when using UDP, there is a risk that a specific file may not reach the recipient or may become unusable due to losses within its structure.

In contrast, TCP ensures guaranteed data delivery with confirmation. If any data is lost or corrupted during transmission, TCP automatically resends it. This retransmission process continues until the files are successfully delivered in their entirety.

Error control

TCP has built-in mechanisms for error detection and correction. Should failures or problems arise during data routing, TCP endeavors to rectify these issues and resends the data. Conversely, with UDP, if packets are lost, the connection proceeds without any intervention or correction.

Transmission order

In information exchange, TCP adheres to a strict sequence for data delivery, ensuring that packets are received in the exact order they were sent. For instance, if a network client sends a photo, followed by a text message, and then an audio track, they will be received in that specific sequence. Conversely, a UDP connection may deliver the text first, then the audio track, and finally the photo.

Furthermore, UDP boasts higher throughput, as it does not burden itself with tasks like connection management and error handling. Based on these facts, it's evident that a UDP proxy is more suitable for applications where minor delays are tolerable, but high-speed data processing is critical.
