The main difference between tcp and udp: analysis of the core differences between TCP and UDP protocols

Hands down, you can tell the difference between TCP and UDP bends.

Proxy IP brothers can not get around these two protocols, but many people have been using the proxy for three or five years can not distinguish their way. Today we will use the most earthy words, from the proxy IP practical point of view nag to understand this matter.

I. Basis of agreement

TCP is like an obsessive-compulsive courier, you must confirm that you receive the package to rest assured, UDP is an acute, the package to the door once thrown on the run. For example, with ipipgo proxy IP to grab data, if you use the TCP protocol, each packet to confirm delivery, although slower, but stable; with UDP, then, may lose a few packets but the speed of whoosh.

 Example of TCP proxy setup (Python)
import requests
proxies = {
    'http': 'socks5://ipipgo_user:password@proxy.ipipgo.com:1080',
    'https': 'socks5://ipipgo_user:password@proxy.ipipgo.com:1080'
}
response = requests.get('http://example.com', proxies=proxies)

II. Core differences look at this table

Proxy IP in the doorway

Using ipipgo's dynamic residential IP for crawlers.TCP protocolIdeal for situations where complete data is required. For example, ticket grabbing scripts, one less packet may miss the ticket information. And with theirStatic Residential IPDoing live push streaming, the advantage of the UDP protocol comes out - even if you lose a few frames of the screen, the audience will not notice.

There is a pitfall to pay special attention to: many proxy tools use TCP by default, if you use UDP to set up separately. ipipgo's client supports dual-protocol switching, and you can unlock hidden skills by checking the box "UDP forwarding" in the advanced settings.

Fourth, how to choose not to roll over

Remember the mnemonic:To be accurate but not fast, TCP carries with it; to be fast but not complete, UDP rushes ahead.It is a good idea to use ipipgo's TK line for cross-border business. The actual test found that with ipipgo's TK line to do cross-border e-commerce, TCP protocol order success rate is 23% higher than UDP. but do real-time data monitoring, UDP response speed can be 3-5 times faster.

V. Practical QA three consecutive questions

Q：Why can't the agent connect sometimes?
A: It is likely that the protocols are not paired. Check the type of protocols supported by the target site. ipipgo's customer service can help with protocol sniffing.

Q: Which protocol to choose between Dynamic IP and Static IP?
A: Dynamic homes suggest TCP to maintain stability, static IP can try UDP. their enterprise version of the dynamic IP support dual protocol concurrency, can automatically switch

Q: How do I test the protocol speed?
A: In the ipipgo client there is a "protocol speed test" function, run for 30 seconds to know which protocol is more suitable for the current network environment.

VI. ipipgo's one-of-a-kind tips

The family has a specialty--Protocol Mixed ModeFor example, if you use TCP to establish the initial connection, the data transfer is cut to UDP. For example. the initial connection is established with TCP and the data transfer is cut to UDP. the measured download of large files can save 15% traffic. this is enabled by default in the Dynamic Residential (Enterprise Edition) package.

For package price, newbies are advised to start with Dynamic Residential Standard ($7.67/GB). There is a hidden trick: from early morning to 8:00 a.m. 30% discount on traffic charges, suitable for brothers who do data backup. If you do business that requires a fixed IP, you can go directly to the static residential package, 35 dollars an IP can be used for a full month.

Lastly, if you are having trouble choosing an agreement, you should ask their technical customer service directly.1v1 program customizationThe last time there was a customer doing overseas customer service system. Last time there is an overseas customer service system customers, mixed with three protocols to lower the cost of 40%, this wave of operation is really 666.
