Abstract: A system and method for enhanced data connections via an asymmetric data network receives incoming modem calls and discriminates those intended for enhanced service Web or other service, for instance by domain name. Those calls destined for that type of enhanced treatment may be received via modem banks or other RAS resources communicating with the PSTN or otherwise, and directed to an enhancement cluster or other nodes or locations for compression, caching, optimization or other processing designed to give the user's Web browsing or other service an improved or more responsive feel. According to embodiments of the invention in one regard, the user IP sessions may be tunneled to the enhancement cluster using a tunneling protocol, such as Layer 2 Tunneling Protocol (L2TP) or others.
