Answer 2

It's a very general question.
Something like "give an example of a car." We present: from Oka to BelAZ.
Usually the question is more detailed: "What can you carry from one to three people on roads built according to GOST at a speed of up to 100 km / h."
Or, perhaps, this is the question - to estimate the possible scale?
Well, then the analogue of Oka is a software solution for Linux assembled on the knee: iptables + squid + mitmproxy.
And if you need something carrier-class in terms of reliability or throughput (analogue: from a lorry to BelAZ), you can look at the solutions:
- Cisco SCE / ASR5xxx
- Sandvine
- Procera
- Huawei SIG
- Ericsson SSR
