Layer 2 link test questions, UDP packet loss-CodePudding

Masters:
My side need to test a layer 2 link UDP and FTP performance, the layer 2 is hire operators to provide a public link,
Using FTP testing found rate can only be about half of the rent rate,
UDP test, found that the length of the contract for 1472 byte high packet loss rate by more than 20%, but the contract length is reduced to 546 byte, the same bandwidth of the UDP flows packet loss rate is decreased to 1%,
Check the pmtu the layer 2 links for 1472 byte,

Also please advise each master and analysis, thanks a lot!

Their top once, don't sink

Be able to transform the public link to describe clearly? Such as the public link long? There are thousands of miles? MPLS is? , etc.

CodePudding user response:

refer to the second floor zhengmx100 response:

can described the public link clearly? Such as the public link long? There are thousands of miles? MPLS is? And so on

Link if completely normal, should not be any package

CodePudding user response:

When using FTP test found rate can only be about half of the rent rate, is up and down the rows? What test way and FTP address, different space from your network and the FTP server is rate is different, which operators to rent? Different operator, fixed-line service level is different (personal experience, the preferred telecom), and what is your demand for the application of network bandwidth, can further negotiation and operators,
Rental is what kind of link access and transmission way, this also has effect on the application of network, optical fiber line, is to know about the way to operators into the public network, leased IP address in general are operators secondary distribution, through transfer operators into the public, so operators how to secondary distribution, use what agreement, how to map all have an impact on network latency,
Is UDP is a go regardless of protocol, packet loss on through operators into the public should be normal, want to ask what is there between sharing conflict processing, such as lost package, parcel is lost, lost package is not or is not to find the way to come back to the destination, and operators of the choice of network structure, and test the address may have something to do, don't quite understand, I make a clear button for remember

The specific situation of the public I am not very understanding, the public network link from Beijing to Shanghai, in your experience will use MPLS? Also hope you can give some advice and interpretation,

Yes, up and down the rows about, test methods using FTP software download upload manner, leased telecommunication networks,
My knowledge of network isn't very experienced and this time we rent is a layer 2 link, I also hope to be able to get some of telecom link details, but I don't know where to start to ask this matter, could you give some advice?

The simple solution to this problem is to find your operator group customer manager complaints, said packet loss is serious,
