How to Understand RFC9564 and the Faster Than Light Speed Protocol

What Is the Faster Than Light Speed Protocol?

As the name suggests, it sounds almost fictional—something out of science fiction. However, RFC9564 proposes a framework where network devices use artificial intelligence to predict the next expected packet in a communication stream. By leveraging learned models trained on traffic patterns, the devices anticipate transmission behavior and react faster than the traditional wait-and-receive model.

In effect, the protocol doesn’t actually break the speed of light. Rather, it reduces latency by removing response delays through predictive packet behavior. Imagine a router or firewall processing a packet before it arrives because it's 99% certain it knows what's coming.

Why It Matters for Networking Students

If you're working on TCP/IP stack enhancements, AI integration into network devices, or transport protocols, this RFC is a goldmine. The blending of AI-driven optimization with traditional networking practices is a signal that protocol research is moving into a new era—one where machine learning becomes embedded into low-level network logic.

For your next computer network assignment, consider exploring:

• Predictive buffering in TCP using AI models
• Latency reduction in multi-hop networks with ML-based packet prediction
• Future challenges in securing AI-enhanced packet processing

Post-Quantum TLS: Eric Rescorla’s Take on the Future of Cryptography

Quantum computing is no longer a futuristic concept—it’s a looming challenge. Eric Rescorla, one of the original minds behind TLS (Transport Layer Security), published an insightful blog exploring how quantum breakthroughs could unravel the cryptographic backbone of today's Internet.

TLS in the Post-Quantum Era

TLS is fundamental to secure communications on the web. From e-commerce to VPNs, TLS ensures confidentiality, integrity, and authentication. However, quantum computers threaten to crack RSA, ECC, and other public-key cryptosystems used in TLS.

Rescorla's analysis looks at how post-quantum cryptography (PQC) can replace existing key exchange and digital signature algorithms with quantum-resistant alternatives. He also discusses hybrid solutions—transitional protocols that combine classical and post-quantum elements for enhanced safety during migration.

Takeaways for Students and Researchers

• TLS 1.3 assignments? Consider implementing or simulating a hybrid handshake.
• Cryptographic protocol design? Research the performance and size implications of post-quantum algorithms like Kyber and Dilithium.
• Security evaluation? Analyze attack models with quantum adversaries and simulate handshake scenarios using PQC libraries.

This is an exciting time for students interested in both networking and cryptography. Expect PQC to become a staple topic in graduate-level coursework and advanced assignments.

DNS Innovations and Challenges at IETF119

The Domain Name System (DNS) continues to evolve, especially to keep up with encryption and privacy demands. During IETF119 in Brisbane, thought leaders like Geoff Huston presented key insights into current DNS challenges and advancements.

The HTTPS DNS Resource Record (RFC9460)

One of the most notable additions is the HTTPS resource record, defined in RFC9460 (Nov 2023). It plays a key role in enabling Encrypted ClientHello (ECH) in TLS. Traditionally, the ClientHello message in TLS exposes the destination hostname, making it visible to middleboxes and ISPs.

With ECH and the new HTTPS record, DNS can help clients encrypt this handshake step, preserving user privacy. This is a crucial shift toward true end-to-end TLS encryption, even before the handshake finishes.

Recent technical analyses have already studied the deployment of the HTTPS record. Packet traces are being shared to help researchers and implementers understand the transition.

What It Means for Your Assignment

• How ECH and HTTPS DNS records change TLS architecture
• Privacy-enhancing DNS protocols (DoH, DoT, ECH)
• Deployment challenges and packet trace analysis of DNS over TLS

Protocol Standardization: How Long Does It Take?

Another eye-opening presentation by Geoff Huston at IETF119 covered a meta-topic: How long does it take to standardize a protocol? Huston analyzed data from the IETF archives and presented charts showing that protocol standardization is slowing down significantly.

Key Stats

• In the past, RFCs could be published within 2 years.
• Now, it takes 6 to 8 years on average to finalize a standard.
• The oldest still-active draft in February 2024 was draft-kunze-ark-38.

Most RFCs fall under either:

• Proposed Standards – intended to be deployed but may evolve
• Informational Documents – explain concepts without prescribing implementations

Why This Is Important for Students

If you’re working on projects involving new protocol design, this insight helps set realistic expectations. Whether you're building a new VPN tunneling protocol or an improved routing mechanism for IoT, understand that deployment is just the beginning—standardization is a marathon.

Assignments can focus on:

• Drafting a mock IETF draft (great for protocol design classes)
• Analyzing the lifecycle of RFCs over time
• Studying delays in consensus and technical debates in IETF working groups

Peering Links: Are We Still Facing Internet Congestion?

Finally, a study by the University of Chicago delves into how inter-ISP peering capacity has evolved. Using data provided by multiple ISPs, the researchers found that:

• Peering link capacity between large ISPs has steadily grown over the last five years.
• Since mid-2021, utilization during peak hours has remained between 30–35%, indicating minimal congestion.

This contrasts with the past when interconnect bottlenecks frequently caused regional slowdowns.

What This Means for Network Students

• How traffic engineering affects peering efficiency
• The impact of CDNs and edge networks on reducing transit demand
• Simulating peering congestion and analyzing BGP behavior during peak traffic

With real data showing underutilized peering links, students can also discuss economic incentives in ISP interconnection and how surplus capacity affects traffic policy.
