Lesson 6Placing Proxy Server within a Network
ObjectiveIdentify the decisions involved in the placement of Proxy Server within a Network

Placing Proxy Server within a Network

You must place Proxy Server between network segments so that network traffic is localized and security is maintained. To improve performance, you can place Proxy Server so that Web objects are cached for:
  1. An entire organization
  2. A location within an organization
  3. A network segment within an organization

A few key differences between placing Proxy Server within the private network and at the edge of the private network are detailed in the MouseOver below.

  1. When using a proxy server on the edge of each network segment, the overall network traffic on the internal network is reduced, because requests for similar content that have already been made by another user on the same segment, do not have to leave the local subnet.
  2. Web objects are cached for the entire organization. Screened subnets are created within the private network, thereby protecting confidential data.
  3. The private network is isolated from the public network, thereby protecting confidential data. Network packets can be exchanged between the private network segments and public network segments, such as between an Ethernet private network segment and an (ISDN) Integrated Services Digital Network public network segment.
