Proxy & Cache

     
 

DataCoveCF appliances also function as a proxy with an onboard cache which secures, simplifies and speeds up Internet access.

DataCoveCF saves requested web pages and other files that users have requested, onto a high performance hardware platform so that successive requests for these pages or files can be satisfied by the cache, rather than requesting it again from the Internet.

This retrieves information more quickly and also reduces Internet traffic itself. A DataCoveCF appliance will typically reduce Internet bandwidth utilization by up to 50%. In addition, web pages that 'hit' the cache are returned instantly giving the perception of a much faster Internet connection.

DataCoveCF appliance is installed on the Local Area Network (LAN) with one or more connections according to the type of connection mode. There are two basic connection modes, Pass Thru and Directed Proxy. In Pass Thru mode, the "network" effectively directs the user through the cache. This can be either via a layer 4 switch or router or if you have a DataCoveCF appliance, through its in-built capability.

In the native form of Pass Thru with transparent caching, DataCoveCF has the same functionality as that involving a layer 4 switch, however, as no redirection to the cache is required, the latency is reduced by two Ethernet hops. Transparent caching allows much quicker and easier installation into existing networks with no need to reconfigure existing browsers. There is also a significant cost saving as a layer 4 switch is not required.

In Proxy mode, the browser is configured with the address of the cache and talks through it directly, which is especially useful when DataCoveCF is replacing a 1st generation proxy.

Tangent goes to great lengths to ensure that DataCove appliances are extremely simple to configure. Once configured, DataCoveCF will operate seamlessly with no need for operator intervention.
