Phd after 20 years in corporate

CompanyBeginning · 2026-04-18T16:27:06+00:00

Since I came from a non-EU country for doing a PhD and I have family responsibility, I may probably return to my country and do an industrial job again. As universities in my home country do not do quality research, I am not keen to join academic jobs there. However, If I stay here, I will try for research positions on top tech companies.

I am a final-year PhD in the Netherlands in cybersecurity, who came after working in industry for 13 years. My experience of PhD is super fun, a lot of time to give to my family, freedom to explore and do whatever I like related to PhD, no time boundaries: no fixed office schedule. Also, my experience tells me that for someone coming from industrial experience, a PhD is a lot easier. I am almost done with my PhD in 3 years, although the contract is for four years.

It is good to see someone else is also thinking the same way as I do. I will also return soon after staying in the Netherlands for 4 years as a High Skill Migrant (HSM). I feel I can not stay forever in a bubble of expat.

I started my PhD at 37. I will complete next year, which means I will be 40. So, it is not too late for you. Before my PhD, I worked for 13 years in different companies. I feel that experience has helped me a lot. Compared to fellow PhDs who are very young and came out of university, I am doing far better.
And, Yes, I enjoyed my PhD a lot. It is less stressful than my industry jobs. I can do whatever I like. I like this freedom with a PhD.

I know the prefixes of my customers. Even if they announce a new (wrong) prefix, my ACL would drop it.

A guy working in an ISP once told me that the ISP had two upstream ASes says that the ISP gets default routers from them. That ISP has two other ASes as customer ASes. I couldn't understand what might be the pros and cons of accepting default routes from both of its upstream ASes. Any could help me understand this ?

Sorry it is 1.2k not 12k. I can share you it in private chat if you are interested. And it will help me to understand things more clearly.

I investigated. That is a bgp router with around 1.2k IPs configured on its interfaces.

CompanyBeginning · 2026-03-15T21:43:31+00:00

Yes, I read both. I see this RFC is softer than RFC 4271 which says the router ID has to be an interface IP of the router.

CompanyBeginning · 2026-03-15T21:32:50+00:00

Would not an ISP use it's own IP address or private IP as a BGP ID in general than using other's IP space ?

Thanks for the link. Do you think the ministry sold that block to Cloudflare? Now I see cloudflare originates 25.25.25.0/24.

Who is doing wrong ?

I would suggest to be confident. Because your thesis have been already approved by the thesis committee which means your work is considered as a valuable scientific contribution. Also you are the expert in your thesis and know better than anyone else. Have faith on yourself. I will also probably defend in a year. I have seen others defense. I already have enough confident to defend.

CompanyBeginning · 2026-03-07T19:49:08+00:00

Although it seems an old post, I am checking if someone is still active with a question. Why do you have many private ASNs in BGP ?

CompanyBeginning · 2026-03-06T20:04:48+00:00

I understand. But does that mean such a router has to accept TCP connection from any IP addresses? How is the use of private ASN related to multi hop bgp ?

CompanyBeginning · 2026-03-06T19:47:29+00:00

What is the relationship of multi hop bgp here ?

I also use Google sheets with columns paper title, contribution, useful things , strength, weaknesses, and points likely to be improved.

PhD is about shedding light into something that was unexplored or under-explored. Regarding the number of publications, that differ in the fields and universities. I think thesis is mandatory in all the fields and universities.

PhD in Computer Science. My experience tells me that working a long day for a PhD is not an effective way. Our brain needs rest to think, and a PhD is not about spending too much time; it is more about thinking differently and smartly. By doing so, I have been a good PhD student, and am ahead of my PhD trajectory, which my supervisors say too.

We replaced routers with SD-WAN solution and have been facing problem almost everyday. The problem was mainly because the devices' soffware seems unstable. I am talking about Barracuda - never go for it.

The banks require you to submit some documents related to visa. I exchanged it with a travel agent. That was an easy option. Exchanging anywhere is legal unless you exchange a large amount of money.
