Network-Based Protocol Innovations in Secure Encryption Environments

  • Using Locator/ID Separation Protocol (LISP) to Optimize Routing in IP Encryption Environments
  • Cisco Systems
This paper examines how recent network-based protocol innovations can be used to simplify the overall deployment, functionality, and operation of networks in which IPsec VPN devices (IVDs) are required--specifically, in Department of Defense (DoD), Intelligence Community (IC), and secure enterprise networks.

The main innovation addressed in this paper is the Locator/ID Separation Protocol (LISP) routing architecture framework, which, when deployed in an IVD environment, addresses some of the major deployment and operational challenges common in IVD networks today.

This paper compares the use of LISP with technologies currently used in IVD deployments today. It also highlights the advantages and differentiation that simplify operations and deployment, and offers current and future enhancements that could change the way IVD networks are deployed.

This paper, penned by a Cisco distinguished engineer, discusses a new routing architecture framework aimed to simplify the deployment and operation of networks containing IPsec VPN devices, which encrypt traffic flows. There are published drafts for the Locator/ID Separation Protocol (LISP) that Cisco proposes at the Internet Engineering Task Force (IETF). Best for the serious routing geeks among us.
