Edge Routers

What are these?

In a nutshell, well, an edge router is a specialized router located at a network boundary that enables an internal network to connect to external networks.

There are some notable differences between normal routers and these Edge routers.

Core routers tend to move packets as fast as possible because they interact less with the outside access network and, therefore, have less novel security threats to consider. Edge routers encounter more complex configuration and security issues and, therefore, focus on those challenges over speed.

Why you would need an edge router.

Edge platforms contain robust security controls, such as traffic decryption and packet inspection; application identification and access control; malware and malicious-URL filtration; and intrusion detection and prevention. They also enhance cloud security deployments with robust tunneling capabilities.

How do they work?

Edge routers work to secure the network edge and protect the core by characterizing and securing IP traffic from other edge routers as well as core routers. They differ from core routers in that core routers forward packets between routers to manage traffic and prevent packet loss, often using multiplexing.
