The development of quantum networking technology will ultimately yield more secure and higher-speed connectivity, but it’s still very early in the game and many challenges remain before it becomes mainstream. While core quantum networking technologies such as repeaters and photonics are being developed, it is security applications – specifically post-quantum cryptography (PQC) – that are likely […]
On the Internet, we use BGP for routing. BGP has no built-in security mechanisms to check whether a prefix belongs to a specific autonomous system (AS). It’s all based on trust. You can advertise whatever you want; the only thing stopping those prefixes is outbound or inbound filters if you have any. The Internet is […]
On the other hand, analysts also say that Google’s move to waive of egress charges should bode well for enterprise customers. “There’s been a huge customer backlash across all cloud computing companies on account of the egregiously priced egress fees. It’s gotten to the point that customers don’t want to move to a new provider […]
We use BGP on the Internet to exchange routing information between autonomous systems (AS). A route leak happens when one or more routes are advertised and accepted by ASes that shouldn’t have these routes. This can have nasty side effects like traffic delays, drops, and security issues. In this lesson, we’ll dive into BGP roles, […]
In a potentially transformative deal for the tech industry, Hewlett Packard Enterprise (HPE) is in discussions to purchase Juniper Networks for $13 billion, according to Reuters. This acquisition could be strategically crucial for HPE as it seeks to expand its reach in the AI and related markets that are becoming increasingly competitive. “HPE is experiencing […]
The data surge in manufacturing is reshaping operations, demanding timely access to data across diverse centers of data that are often housed in varying footprints, from small server rooms near the plant-floor to large colocated data centers. However, given the extended obsolescence and update cycles in manufacturing to maintain non-stop production, those data centers are […]
Aiming to promote IPv6 innovation and accelerate the construction of next-generation network infrastructure toward Intelligent Indonesia Digital Vision 2030 & 2045, IPv6 Industry 2023 was held in Indonesia, gathering government regulatory authorities, carriers, and industry organizations. At the event, Ryan Qiu, Vice President of Huawei Data Communication Product Line, delivered a speech titled “IPv6 Enhanced, […]
It’s all too common for network engineers to spend more time hunting for the source of network performance issues than fixing them. The lack of performance metrics is not the issue. It’s often a case of too many metrics obscuring the real root of the issue. In multi-cloud hybrid networking environments, problem validation, isolation, and […]

In the BGP attributes and path selection lesson, I explained that BGP uses a list of attributes to determine the best path. Somewhere down that list, one of the things BGP checks is whether we have an (external BGP (eBGP) or internal BGP (iBGP) path. BGP prefers eBGP paths over iBGP, which we’ll verify in […]
