I passed my CompTIA Network+ exam this week and would like to share some insights on computer networking.
The last time I delved deeply into networking was during my data-communication and TCP/IP courses in college, approximately 20 years ago. While I have utilized many of those skills since then, much of the knowledge that went unused has faded over time. To prepare for the Network+ exam, I dedicated significant time to refreshing my network engineering skills, leading to a few realizations.
Significant advancements have occurred in the upper layers of the networking stack (ISO model), with new protocols and standards being quickly and widely adopted. For instance, TLS 1.3 enhances encryption, and QUIC/HTTP3 improves web server speeds. However, the lower layers of the networking stack have seen relatively little change. Despite IPv6 being formally released in 1998, its adoption has been slow. Notably, the U.S. Department of Defense only mandated its adoption in 2021, with a projected completion date in 2026. This slow evolution can be attributed to physical limitations and costs, but the primary reason seems to be the lack of compelling drivers. Even though all North American IPv4 addresses have been exhausted, purchasing one on a secondary market is still feasible at a premium cost, reducing the urgency to transition to the more complex IPv6 standard.
Nonetheless, innovation continues at the lower layers, driven by specific needs. For example, WiFi has seen incremental upgrades due to the demand for faster internet speeds. Similarly, with the rise of AI, we are witnessing the rapid development and deployment of new networking technologies such as InfiniBand and Ultra Ethernet. These protocols are designed to accelerate communication at the lower layers of the network stack, catering to high-performance, data-intensive applications.
While this observation may not lead to a concrete conclusion, it suggests that we might see more rapid advancements in the lower layers of the networking model as new business drivers emerge due to AI.
Incidentally, the current Network+ syllabus and exam does not yet cover InfiniBand or Ultra Ethernet. 😢
