Improved Security/Encryption

According to the World Economic Forum, cyberspace crimes will cost the global economy $445 billion in 2016. Gartner estimates that by 2020, companies worldwide are expected to spend around $170 billion on cybersecurity – a growth rate of nearly 10 percent in the next five years.

With session-based routing, enterprises can realize improved network security. Session-based routing enables a clear view into the source and the destination of packets as they travel from private to public to private networks, allowing operators to enforce security policies more easily, facilitate a path and then encrypt information along that path. This guarantees the integrity of the path and prevents "man in the middle" and "spoofing" attacks. The session-based router is also smart enough to know what data is already encrypted, which means network operators can avoid double-encrypting information to prevent fragmentation and minimize latency. It can also encrypt information that might not already be encrypted or does not meet minimum security policy criteria.

The foundation of session-based routing is built on a zero-trust model. A packet is not forwarded on a network without an explicit policy for doing so. No broadcast domains are default routes for hackers to utilize once they have compromised one machine and are looking to move onto others, and data exfiltration is stanched at its source.

The Internet is built around routers, yet there has been little innovation in routing itself for decades. Early networks mainly involved just packets and flows within private networks. With the rapid expansion of the Internet in the 1990s, the first round of modifications focused on improving "speeds and feeds" through specialized hardware.

The router of yesterday was not designed to handle the mobile and cloud applications that exist today because it was originally built to send packets between a series of computers, not deliver services across both private and public networks. As a result, an entire industry has emerged around routers to deliver bolt-on functionality such as firewalls and load balancers.

What's more, controlling how packets move between endpoints and through routing devices often involves adding a new network on top of the existing network, referred to as an overlay. Overlay networks don't address the underlying issues with networking, they compound them, which can be complex and expensive. Enabling all of these technologies to work together reliably and securely is very difficult, making the Internet as we know it complex, fragile and insecure.

The router of tomorrow needs to operate differently and more intelligently to handle today's network demands, as well as the demands of the future, such as those for IoT and increased video traffic driven by collaboration, monitoring and virtual reality. That's where session-based routing comes in. A software-based router that is session-oriented and deterministic can drastically simplify the network, eliminating complexity such as middleboxes and tunneling and overlay technologies, and making it possible to deliver all the end-to-end benefits enterprises need, such as native security/encryption, policy-based routing and more.

In this slideshow, 128 Technology explains the concept of session-based routing and outlines the four key reasons why session-based routers will fix the Internet.
