SOHOs are not an integral part of the enterprise network and therefore deficient in security, performance, management and accountability. Existing enterprise networks consisting of Layer 1 or Layer 2 circuits connectingCPE-based routing, firewall and encryption systems are prohibitively expensive for SOHOs due to the high cost of the access circuits, CPE and truck rolls. IP service switches from companies such as CoSine Communications, Nortel's Shasta unit, and Lucent's Spring Tide division break through the economic barrier by providing encryption and firewall, virtual routing and QoS within the network. There are also soft dollar benefits. Privacy and security are the same as that provided at large enterprise sites.
Traffic is prioritized and response times are guaranteed.
Since IP service switches support virtual router services, managed router services can be offered cost effectively. Managed router services are more flexible, enabling fast provisioning and quick network changes, which imply shorter time to market. In addition, managed router services can be customized and the transition to IP services made without changing or disrupting existing private routing schemes. IP service switches enable cost-effective management of traffic flows originating from all sites including small ones that otherwise cannot achieve traffic flow control at affordable prices. Advanced IP service solutions built upon IP service switch technology provide SOHO network connectivity with security and performance identical to that available at large sites at one-third the cost, while greatly improving service reach.
