What is Synchronization?
update
f_new f_old
request
Server Client
• Keeps files in two or more locations matched with each other.
• If you add, change, or delete a file in one location, you can do the same
with the other locations that you choose to synchronise.
• There are two types of Synchronization: 1) One way 2) Two way
Standard Techniques :
Caching: “avoid sending same object again”
- Only works if objects completely unchanged
- server has new file but does not know old file
Standard Techniques :
Compression: “remove redundancy in transmitted data”
- update without sending entire new file
- robustness: receiver data may get corrupted
- does not apply when sender doesn’t know data at receiver
Network Administration :
• Network Connectivity setup
Physical (Manually )
Logical(By using software eg . PACKET TRACER)
• Client Server connection
• DNS and DHCP configuration
Network :
Network setup : (logically)
Eg of N/W Setup by Packet Tracer
Network Protocols :
• DHCP (Domain Host Controller Protocol): Auto allocation of IP
Addresses for client nodes
• DNS (Domain Name System):Naming services provided for access
• FTP (File Transfer Protocol): Exchange of information between Clients
and servers
Security Administration :
• Authorization control
– Our network team and the monitoring system will constantly monitor the
system for suspicious activities and access using ADCS and Group Policy
Management.
– Certification authority is used to provide digital certificates for highly
important or sensitive data transfer.
Continued :
• Encrypted Folder - Secure Storage
– 128-bit SSL for transferring sensitive data.
– Nobody can eavesdrop such communication.
– Files can also be transferred using FTP/FTPS over SSL
• Application Security
– You can share or publish your files/folders & specify
different permissions for different users as in FTP.
Continued :
• Network Transfer Security
– without a private encryption key, nobody, even our Operation Managers
can’t read your files.
– Authorized LAN Chat with real time password sharing.
Troubleshoot :
• Problems with Syncing
• Synchronization errors
• Devices not listed with sync centre
• Connected devices run out of space
• Sync deletes a file
• Problems like partnership lost
Troubleshoot Solutions :
• Check & maintain physical connections
• Place Reminders
• Time to Time report generation
• Report Analysis
Future Enhancements :
• OS installation on clients using image file on the
server using WDS
• All in one Booting, Shutdown, Restart, Log off,
etc.
• Authorized LAN Chat with real time password
sharing.
• Wireless synchronization using Wi-Fi
Use :
Updating web pages (Software Updates)
Data mirroring (web servers, accounts, collections)
Handheld synchronization (portable devices like PDA , I-pod)
Web access acceleration (Compression)
File compression (save disk space)
Content distribution networks
Solution :
Using : Windows server 2008
(Client-Server Architecture)
Or : Sync centre (Small Networks)
Management of Files using group policy
to provide rules and regulation for
Synchronization
