For many years we have been active in network engineering for various large ISPs. With this background, we offer professional and state-of-the-art Network Engineering as a Service.
In addition to ISPs and carriers, we also work for SMEs and start-ups for whom an Internet connection is mission-critical, but perhaps not their main business purpose and/or whose network does not justify the employment of a full-time network engineer.
We often encounter enterprise customers who have been recommended "simple" solutions for technical challenges like IPv6 or BGP. On common search engines, one of the first auto completions for "Linux IPv6" is usually "... disable". For BGP, you get "too complex for the inexperienced; better don't". But as usual, sticking to old technology ain't the solution of the leaders, nor is it economically sustainable or viable. We support you.
We assist you in topics like
If you would like to set up your company's Internet connection redundantly, if you need help with multi-homing, routing, BGP, IPv6 roll-out and dual-stack operation, capacity planning, vendor management, sourcing or set-up and operation of critical network services such as DNS, please contact us.
Btw: If your network is already multi-homed and you have delegated your network management to one of your transit providers, reconsider if this contractual arrangement actually serves the interests of your company or rather the intrinsic interests of your ISP.
Why should we care about IPv6?
Here an example:
Remote work is the new normal in modern working environments, and so are technologies to secure communication, like VPN. At the same time, FTTH is rolled out in many places in Germany and generally well-adopted. Many of the FTTH carriers are relatively new in the carrier market. Due to IPv4 address space exhaustion in November 2019, it is not uncommon for them to only have limited IPv4 address resources. To address this shortage, these providers use a technology called CGNAT to assign IPv4 addresses. The use of CGNAT results in a frequently changing IP address, which is no issue for normal private home user purposes, but renders VPN connections for remote employees basically unusable.
We recently observed a case in which an otherwise working VPN setup (CAPEX, already written off) was replaced with a cloud-based zero-trust solution (OPEX) from an industry-renowned provider to ensure stable remote office connections.
This issue does not exist with IPv6. IPv6 address space is readily and sufficiently available and providers usually use native address allocation without CGNAT.
Properly rolling out IPv6 in this company network including the VPN gateway, and pointing remote users to the VPN gateways IPv6 address would have saved all additional OPEX costs.
Why should we bother with BGP?
What impact would a 48-hour network outage have on your company? The simple case of an excavator grabbing a cable can usually be solved in a day. However, unfavourably localized cable breaks can also cause much longer interruptions. Bridges are critical infrastructures not only for road traffic, but sometimes also for cable routes. Freshly installed guardrail posts are often necessary for increased road safety, but sometimes can also slice and dice a cable. A properly installed, redundant network connection significantly increases resilience of your Internet access.
Most of the time you can also benefit from optimized routing. Destinations that are more difficult to reach via one ISP can possibly be reached more directly via another ISP.
It's true, BGP and connecting to multiple ISPs to become multi-homed requires experience in order to function smoothly and effectively. This is our offer to you.
