What is Slow Path and Fast Path?

Fast path, slow path

Packets that need minimal or normal processing take the fast path, and packets that need unusual or complex processing take the slow path. Fast path packets correspond to data plane tasks, while slow path packets correspond to control plane tasks.

What causes asynchronous routing?

Asymmetric routing is when the flow of packets in one direction passes through a different interface than that used for the return path. This can occur when traffic flows across different layer 2 bridged pair interfaces on the firewall or when it flows across different firewalls in a high availability cluster.

How can you prevent asymmetric routing?

The solution to this problem is to adjust the placement of the firewalls or internal routing such that traffic in both directions flows through the same firewall, even if incoming traffic enters the network through a different router than the router that handled the matching outgoing traffic.

Why is asymmetric routing bad?

Asymmetric routing can be bad, mainly because you risk packets being delivered in the wrong order, but again, depends greatly on the topology you’re talking about.

Do firewall rules have to be symmetric?

Communication is free to flow both ways once initiated from the allowed source to the allowed destination over the allowed port and/or service because modern firewalls are stateful. A symmetric rule isn’t necessary because of this.

What is the difference between symmetric and asymmetric routing?

Asymmetric Network: An asymmetric network has multiple routes for incoming and outgoing network traffic. As such traffic takes a different route when entering or exiting the network. Symmetric Network: A symmetric network has a single route for incoming and outgoing network traffic.
