The difference between intranet and extranet

The difference between intranet and extranet is different in nature, access rights, security, address space and transmission rate.

1, with different properties.

Extranet is a global public information exchange network with extensive network connections, wide coverage and rich information resources. Intranet generally refers to the local area network within an enterprise or organization, which mainly serves the information exchange within the organization.

2. Different access rights

Any computer with network connection can access the extranet, which is open and open. However, the access rights of intranet are usually strictly restricted, and only people with specific rights can access it.

3. Different security.

Because the external network is open, the security of the external network is relatively worse than that of the internal network. However, the security of the intranet is relatively high because of its closeness and access restrictions.

4. Address spaces are different.

The IP address space between intranet and extranet is also different. Internal networks usually use private IP addresses, while external networks use public IP addresses.

5. Different transmission rates

Due to the limitation of small geographical scope, the transmission rate of internal network is usually much higher than that of external network. For example, the transmission rate of LAN is 100 MB/s, the transmission rate of FDDI is1000 MB/s, while the relay rate of WAN is only 64kb/s or 2.048Mb/s in China, and the upper limit rate of end users is usually14.4 KBP/s. ..
