How much bandwidth does GlobalView URLF require for communication with the GlobalView Network?
Commtouch has developed an auto-learning Locally Cached Database (LCDB) that adjusts its content according to the actual browsing habits of the users served. The result is local categorization data for over 99% of all queries. For the small percentage of the cases where a query is transmitted to the Commtouch GlobalView Network, the query and result usually add up to no more than 1kB. This is an order of magnitude less than an average Web page which could be tens to hundreds of kilobytes. Commtouch has performed measurements within enterprises using GlobalView URL Filtering and found that the queries to the cloud amounted to a mere 0.1% of total HTTP traffic. The additional traffic created by Commtouch’s cloud architecture is therefore negligible.
