Fudan for the first time!Woning the top computer network conference student research competition undergraduate group gold medal

A few days ago

Hosted by ACM (Note: International Computer Society)

SIGCOMM (Note: International Authoritative Computer Network Top) 2022 is held in the Netherlands

After strict thesis review and defense link

Huang Run, a level 19 undergraduate student in computer science and technology major in our school

In the fierce competition

Start from the players at the top universities at home and abroad

Get the gold medal of the undergraduate group (first place)

This is the first time in our school

In the top international academic competition of computer network

Get this award

In addition

In the ACM Academic Contest Annual Finals in March next year

And the winner from other top conferences

Compete

Hosted by ACM

Global well -known academic competition

ACM Student Research Competition (Student Research Competition)

(Note: referred to as ACM SRC)

Multiple international top academic conferences hosted by ACM each year

Be held up

This time Huangrun is at the SIGCOMM conference hosted by ACM

Get excellent results

Huang Run and the instructor Chen Yang

2021

Huang Run joined the SONIC Lab mobile system and network research team (MSN)

Under the guidance of Associate Professor Chen Yang and Professor Wang Xin

Carry out computer network -related scientific research work

The title he participated in this contest was

"Locating CDN EDGE Servers with Http Responses"

The winning results proposed a use

HTTP (Note: Ultra -text transmission protocol) Geographical information in the response

Method of judging CDN (Note: Content distribution network) node geographical location

Realized the database of more than traditional IP geographical positioning database

Higher positioning accuracy

Based on this

He also for web developers and researchers

Provided a set of open source tools

Used to judge web resources in CDN nodes

Cache status, distribution node geographical location

And information such as CDN providers

"The moment when I know the dissertation is included, I was very excited." Huang Run said

"Your thesis proposal has a clear motivation,

It also has an important impact on the vertical research on CDN in the future,

It is possible to be valuable for the industrial and academic circles. "

The thesis review has encouraged him

Affected by the epidemic

Huang Run completed the defense link online

Facing the questions from the top professors in the camera

He calmly responds and performed well

Win the entry voucher to the finals for yourself

"Under the disadvantage of being unable to answer offline,

Being the first place is worthy of congratulations,

His efforts were recognized by the international platform. "

Instructor Chen Yang said

Speaking of the results of this paper

Still from his daily learning and research

then

Members of Huang Run and Chen Yang Laboratory Research Group

CDN -related measurement work

During the research process

Huang Run noticed that some CDN providers have a specific HTTP response header

As a result, it is used to use them

The idea of ​​judging and distinguishing between different CDN providers

After the preliminary results are sorted and reported to Chen Yang

Chen Yang believes that this research value and practical significance

And encourage Huang Run to continue to dig deeper

Strive to publish DEMO papers on SIGCOMM

that's it

Under Chen Yang's patient guidance

Huang Run learns to write the paper from 0 to 1

And successfully complete the writing of the paper

Huang Run said

This is the unexpected joy of the research work

"Unexpectedly" on the road of scientific research

Behind it is perseverance exploration

"Thank you Professor Chen Yang and the classmates of the laboratory,

This award is mainly due to their careful guidance and help. "

Huang Run said

"I will be more firm in the future

Research in the field of network,

Efforts to achieve a faster and more open Internet. "

Link: What is ACM SRC?

The International Computer Society (ACM) is the world's largest professional academic organization in the world, which brings together computers, researchers, people and students in computer fields in the world. The ACM Student Research Competition (SRC) began in 2005 to provide a platform for undergraduates and graduate students worldwide to show and exchange their research results. SRC is held at the top three international top academic conferences such as SIGCOMM, SOSP, MOBICOM, Chi, ICSE, Siggraph and other international top academic conferences every year. ACM SIGCOMM is the top international academic conference in the field of computer networks. It only hires dozens of high -level papers each year.
