How to manage china map data in combination with Akamai Edge Delivery Services

Connected Cars and Akamai

during the last month I have been working on a project with one of our automotive customer.

The Car manufacturer likes to provide all kind of Software Updates to his Cars/Customer as part of his “Connected Cars" initiative.

This should all be done via Mobile Networks (FOTA=File over the Air).

To ensure that the Data is delivered reliable, secure and fast they decision to use Akamai.

 

The data which will be provided via FOTA can be mainly separated into Flash and Map updates.

Because the Car Manufacturer does sell cars on a global scale this does also include Map Data for China.

 

China Map Data

But there is something special if it comes to China Map Data. The Chinese Government has a strict policy if it comes to Map Data.

 

Due to national security concerns, the use of geographic information in China is restricted to entities that obtain a special authorization from the administrative department for surveying and mapping under the State Council. Consequences of the restriction include fines for unauthorized surveys, lack of geotagging information on many cameras when the GPS chip detects a location within China, incorrect alignment of street maps with satellite maps in various applications, and seeming unlawfulness of crowdsourced mapping efforts such as OpenStreetMap.

Aside of restrictions to mapping activities there are also laws, rules and regulations in place which explain how Internet Map Provider need to manage China Map Data. Most of them are described inside the “People's Republic of China Surveying and Mapping Law”.

 

To make this easy to understand (or at least trying to make it easy) the “National Mapping Agency of China” did release a Document called


““Notice on Strengthening the Management of Internet map”


This Document contains 12 Rules about how Internet Map Provider need to manage china map data to be compliant with the several Chinese law.

You can find a copy of a translated version of this document below (see Appendix A).

 

China certified Map Provider

Because of this regularities it seems best practices at the market to use China Local Map Providers.

There exist certain China based Map Online Providers which have been certified like:

  • Baidu Maps
  • Tencent Maps
  • Sogou Maps
  • AutoNavi Maps
  • Tianditu Map World
  • NavInfo Maps

 

Our customer did decided to go with a two vendor approach. He does use Map Provider A for Map Data outside China and Map Provider B for Map Data inside China:

Akamai Edge Server Delivery and China National Mapping Agency Rules

Point number 5 of the Document “Notice on Strengthening the Management of Internet map” does mention:


Fifth, to provide Internet map service shall not be located outside the database server (including Hong Kong, Macao and Taiwan regions).


So it seems like the map database server cannot be located outside of China mainland.

But our Architecture did look like this:

First thing which we can figure out is the usage of Akamai Edge Server from inside China.

This service is called Akamai ChinaCDN and helps to improve Performance.


Usually this Service is used by Customer which do not have a presence at China (no Data Center/Origin inside China) but still deliver that Content with a good User Experience.


To be able to use the Akamai ChinaCDN with an Origin inside China you will need to get a special approval from the Akamai ChinaCDN Product Management. That´s to ensure that Akamai stays inside China regulatory.


The second thing which you can spot out is the fact that certain Akamai Edge Server and/or clients are not located inside China: This cases are expected to provide the best User Experience. The question here is "are we breaking Rule Number 5?":


Fifth, to provide Internet map service shall not be located outside the database server (including Hong Kong, Macao and Taiwan regions).

(source China National Mapping Agency)


To answer this question we need to understand that this Rule does mention the term "database server". Akamai Edge Server are not counted as “database server”. Instead they are so called Surrogates which do not store data persistent. Instead the Data is only cached temporarily inside the Edge Server Caches. 


The situation would change if we would use Akamai Netstorage, in such a case we would store Data persistent.

The Akamai Edge Server will always need to go forward to the "database server" to get the map data initially. So the Akamai Edge Server are not considered as the "database server" which means rule number 5 does not apply here.


In addition Akamai does not record the visitor activities/data and will not keep the map data all the time.

Real world example

  • I am located outside of china.
  • I visit a website which does provide China Map Services like http://ditu.amap.com/ (AutoNavi).
  • AutoNavi Origin is located in China and they are Certified by the China Gov.
  • My Browser cache does store Map Data provided by AutoNavi inside the Browser Cache.
  • Next Time I visit http://ditu.amap.com/ some of the content will be served from my Browser Cache.

Questions:

  • Is my computer now counted to be a “map database”?
  • Will I run into trouble if I would visit China white my PC?
  • Will AutoNavi gets shutdown by the China Gov because they have the content delivered and stored to somewhere outside of China from their China origins?


None of the action will result into breaking China Rules because the Browser Cache, like the Edge Server Cache, is not counted as an “map database”.


Conclusion

China Maps can be delivered via Akamai Delivery Services.

This for sure will help to improve End User Experience
