Domain name list M03.Website route device R00 can include routing rule table R01.Mapped according to regional parsing module M01, website
Table M02 and access domain list of file names M03 can determine the access domain name addresses of file.
Wherein, the terminal user Tc in regional c needs to access the file in file storage device Fdn, Fa1, Fe1, regional d
Interior terminal user Td needs the terminal user Ta accessed in the file in file storage device Fdn, regional a to need to access file
File in storage device Fe1.
Consider that terminal user Tc accesses file storage device Fdn scene, terminal user Tc first accesses website mapping dress
Put M00 and obtain access domain name addresses.
Website mapping device M00 can determine the corresponding access domain name addresses of file storage device Fdn according to following steps：
Step 1：It is determined that needing the file storage device accessed to be file storage device Fdn；
Step 2：Determine that terminal user Tc locations are area c by regional parsing module M01；

Website Ab；
Step 4：The acceleration website Ab that the file storage device Fdn and step 3 determined with step 1 is got, by accessing
The access domain name addresses that domain name list M03 inquiries get file is Ab.Ad.Fdn.
When terminal user Td accesses file storage device Fdn, website mapping device M00 determines corresponding according to above-mentioned steps
When accessing domain name addresses, corresponding acceleration website is not found in step 3, using acquiescence website default, corresponding access domain
Name address is Fdn, and this is the direct-connected situation for accessing file storage device of terminal user.
Other corresponding file storage devices of terminal access are also similar.Finally, terminal user Tc accesses file storage
The access domain name addresses obtained during device Fdn is Ab.Ad.Fdn, and terminal user Td accesses what is obtained during file storage device Fdn
Access domain name addresses is Fdn, and terminal user Tc accesses the access domain name addresses obtained during file storage device Fa1 and is
It is Ab.Aa.Fe1 that Ab.Aa.Fa1, terminal user Tc, which access the access domain name addresses obtained during file storage device Fe1, and terminal is used
It is Aa.Fe1 that family Ta, which accesses the access domain name addresses obtained during file storage device Fe1,.
Assuming that Ab->Ad->Some link of this circuit of Fdn breaks down, and at this moment deletes terminal in website mapping table M02
Tc to Fdn map record will cause the direct-connected file storage device Fdn of terminal user Tc to carry out file access.
Convenient for statement, the example of the access domain name addresses in Fig. 3 is named with accessing the site name on website chain, but this hair
Bright embodiment is not limited to this naming method.
If what queried access domain name list M03 was obtained is the domain name of file storage device, direct-connected access；If
What is inquired is the domain name for accelerating website, then can be determined by routing rule table R01 from website is accelerated to file storage device
Route.
It is each to accelerate website to include own domain list of file names and upstream domain name list, as shown in figure 4, accelerating what website Ab included
Own domain list of file names be (Ab.Ad.Fdn, Ab.Aa.Fa1, Ab.Aa.Fe1), upstream domain name list for (Ad.Fdn, Aa.Fa1,
Aa.Fe1), the own domain list of file names for accelerating website Aa is (Aa.Fa1, Aa.Fe1), and upstream domain name list is (Fa1, Fe1).
Own domain list of file names and upstream domain name list are by routing rule table R01 centralized maintenances, it is necessary to be advised when changing by route
Then table R01 is synchronized to website.
So that terminal user Tc accesses file storage device Fa1 as an example：
It is Ab.Aa.Fa1 that website mapping device M00 inquiries, which obtain accessing domain name addresses, and request agency is accelerated into website Ab；
Ab inquiry own domain list of file names (Ab.Ad.Fdn, Ab.Aa.Fa1, Ab.Aa.Fe1), finds corresponding domain entitled
Ab.Aa.Fa1, then finds its corresponding upstream domain name Aa.Fa1 again, proxies the request to acceleration website Aa；
Accelerate website Aa inquiry own domain list of file names (Aa.Fa1, Aa.Fe1), the upstream domain name for finding correspondence domain name is
Fa1, file storage device Fa1 is arrived by file access request agency；
The access request of file storage device Fa1 processing terminal users, completes file access.
Terminal user is a chain type request to the access request of file, accelerates website Ab and Aa according to own domain list of file names
The route of own node is completed with upstream domain name list, file access is finally completed by file storage device Fa1.

Entitled Fa1；
A.3 resynchronisation accelerates website Ab configuration, allows it to support domain name Ab.Aa.Fa1 access and set corresponding upstream
Domain name is Aa.Fa1；
A.4 website mapping device M00 is finally reinformed, access domain list of file names M03 and website mapping table M02 is updated；
A.5 website mapping device M00 receives first new in access domain list of file names M03 after website route device R00 notice
It is Ab to increase a website, and file storage device is Fa1, the entitled Ab.Aa.Fa1 of access domain record；Then website mapping table is changed
M02, by designated area to Fa1 access map to Ab.
b:When receiving existing redundant rule elimination instruction, above-mentioned newly-increased Ab.Aa.Fa1- is such as deleted>Aa.Fa1->Fa1 is advised
Then, direct-connected access is changed to, website mapping table and access domain list of file names can be updated by website mapping device, successively from most downstream
Website starts to delete corresponding routing rule toward upstream stations.Specifically, can be realized by following steps：
B.1 website map record and domain name access note that website mapping device M00 is increased newly in deleting successively a.5 are first notified
Record；
B.2 sync plus white website Ab configuration, what is increased newly in deleting a.3 itself accesses domain name Ab.Aa.Fa1 and upstream domain
Name Aa.Fa1；
B.3 sync plus white Aa configuration, what is increased newly in deleting a.2 itself accesses domain name Aa.Fa1 and upstream domain name Fa1；
B.4 if file storage device Fa1 no longer needs to provide file access services synchronization Fa1 configuration, delete its oneself
Body accesses domain name Fa1.
c：When receiving the instruction of existing rule adjustment, if desired for by the Ab.Aa.Fa1- increased newly in a>Aa.Fa1->Fa1
It is adjusted to Ab.Fa1->Fa1, can increase new route toward downstream since the website of most upstream, pass through website mapping device successively
Website mapping table and access domain list of file names are adjusted, corresponding old rule is deleted.Specifically, can be realized by following steps:
C.1 a routing rule Ab.Fa1- is increased newly by the way of in a>Fa1；
C.2 routing rule Ab.Aa.Fa1- is deleted by the way of in b>Aa.Fa1->Fa1.
