Want a replacement of Cisco ISR 4331 router. We need 100 Mbps to 300 Mbps router and 2 to 4 Gigabit port. Please help me.
For that small port count and throughput the Juniper SRX branch series in packet mode instead of as a firewall would be more that sufficient. The SRX300 would fit those requirements.
These are aimed at firewall specs but you get the basic stats
How to change to from firewall to router (flow to packet based)
