Writing of software or its modification for serious routers to protect against attacks?

I want to write the firmware for the router (your first home), and then for less healthy (as in a data center).
They seem to be C written. The purpose of writing firmware - filtering DDoS attacks
This necessarily need to write the entire firmware, or you can edit the existing one?

What language better to write? What you need to learn for this case? (it is clear that we must fully explore the Internet and other networks, protocols, etc.)

Terrible misunderstanding of the problem. For "serious routers" don't write the firmware, they are setting up the means provided by the manufacturer.
PS: I have more suspicion that you do not have any of Didos attacks, or are they just minor attacks. Can provide more technical information about the attacks on you?
Cruel didos, punished at worst. The ass is already torn don't know what to do. The hoster already on the wall says move out or ban. - jack commented on April 4th 20 at 00:37
why not write to them firmware? And if you really want? Configure how? I need to defend myself. Channels healthy find. How to filter that? - jack commented on April 4th 20 at 00:40
@jack, have not seen the technical data and curves for the hands and 1rps can be "cruel didos"
1. exit from this hoster
2. themselves a hundred times wrote about cloudflare was unable to connect? - Judah.Heidenreich75 commented on April 4th 20 at 00:43
Configure how

again, configure the equipment provided by the manufacturer "serious routers". - Judah.Heidenreich75 commented on April 4th 20 at 00:46
@Judah.Heidenreich75, hooked already. - jack commented on April 4th 20 at 00:49
@jack, i.e. "Cruel didos, punished at worst. The ass is already torn don't know what to do." this is the maximum technical information about the attack? Well then I can only advise to hire a normal technician. - Judah.Heidenreich75 commented on April 4th 20 at 00:52

DDoS attacks are on the channel and on the app.
If the attack on the canal - there is nothing you can do in principle.
If the attack is on the app - filter the packets, is a firewall. No need to write any firmware. just configure the firewall.

it is clear that we must fully explore the Internet and other networks, protocols, etc.
But with this and perhaps start.

No IOS even super-puper-Mega-awesome, stylish, youth, and written in Assembly language will not help against ddos attacks. Only a powerful hardware and only anycast bgp
Large TV purchase. We need to filter traffic on the router to then there was only the useful traffic. - jack commented on April 4th 20 at 00:41
@jack, what's the point ? Still ddos dedicated for your services will be the uplink operator to score garbage - Einar commented on April 4th 20 at 00:44
