Real Private Routing Over the Public Network
Allegro Networks is testing a new kind of router, called a multi-router, designed to turn private network routing into a commercial service.As service providers edge their way into an increasing number of network functions that large enterprises traditionally managed in-house, security and control remain hurdles to outsourcing. In the case of routing, organizations with mission-critical traffic generally invest in pricey routers, housed and managed on site, rather than relinquish their autonomy to a more public system offered by carriers. Allegro Networks of San Jose, Calif., is testing a new kind of router, called a multi-router, designed to turn private network routing into a commercial service. Calling the innovation a "real private network," it is built to provide more reliability than a virtual private network at less cost and effort than a fully dedicated system. Although some huge organizations, including the U.S. Postal Service, do procure such a service, it is not cost-effective for carriers to offer it on a widespread basis; it generally would not be any cheaper or easier for a service provider to buy and maintain private independent routers for the enterprise than for the enterprise to do so itself.
The multi-router allows carriers to support a multitude of physically separate routers, which are leased by enterprises, over a single system. It is built to give enterprises the isolation and control of a dedicated network and at the same time give carriers the flexibility and scalability of a public service.
