The "Mobile Edge" Architecture for Mobility, Security & Convergence in Enterprise Networks
Today?s enterprise networks are primarily built with a "fixed edge" where users and devices connect to the network by plugging a cable into a port in the wall. Security in such a fixed edge network must be applied to ports in order to protect the network from unauthorized users and devices. However, mobility breaks the fixed edge concept of port-based networking and requires a "mobile edge." The mobile edge is a revolutionary concept, but one that is evolutionary in deployment. The mobile edge is a new way of connecting users to information that transcends the enterprise network perimeter, appearing wherever the user needs access to information—in the corporate office, in a regional or branch office, at retail outlets, at home and on the road. Deployed as an overlay to existing networks, the mobile edge delivers the mobility that users demand, the security needed by the business, and the converged multi-media network that realizes cost savings for the bottom line.

The Mobile Edge Architecture—A New Approach
The mobile edge is an overlay network consisting of both hardware and software. It makes use of existing high-speed networks—the enterprise LAN, the enterprise WAN, and the Internet. The mobile edge does not replace these existing networks, but deploys on top of them as a service overlay, preventing disruptive equipment changes and preserving existing investment. Read this white paper to learn more about this approach and see how the mobile edge can deliver benefits like freedom of access to information, identity-based security and dramatically transformed network economics.
