DPI: Managing Data Traffic in LTE Networks

Long Term Evolution (LTE) is the true heir to the 4G moniker and a pure evolution of 3G wireless networks. LTE offers the promise of a pure, all-IP converged core network instead of the separate circuit- and packet-switched networks used in current cellular systems.

At the same time, with “all-IP” networks, wireless carriers have to prepare for all of the challenges that today’s Internet service providers (ISPs) face:

  • Will peer-to-peer (P2P) traffic clog the networks?
  • How to guard against distributed denial-of-service (DDoS) attacks?
  • How to prepare for dealing with ever-emerging new threats?
