Hedge 266: SR/MPLS

When most people think of segment routing (SR), they think of SRv6–using IPv6 addresses as segment IDs, and breaking the least significant /64 to create microsids for service differentiation. This is not, however, the only way to implement and deploy SR. The alternative is SR using MPLS labels, or SR/MPLS. Hemant Sharma joins Tom Ammon and Russ White to discuss SR/MPLS, why operators might choose MPLS over IPv6 SIDs, and other topics related to SR/MPLS.

You can find Hermant’s recent book on SR/MPLS here.

Hedge 265: Out of Band Networks

Out of band management networks were once more common than they are today. Should we go back to building out of band management networks? Should out of band management networks be virtual or physical? How can we sell out of band management networks to the folks paying the bills? Daryll Swer joins Tom Ammon and Russ White to discuss the importance of OOB management.

Hedge 264: Documentation and Tech Debt

On this episode of the Hedge, Eyvonne, Tom, and Russ talk about topics near and dear to every network engineer’s heart–documentation, legacy, and tech debt. What should our philosophy of documentation be? What are legacy, end of life, and tech debt, really?

Hedge 263: NFTs


 
How do Non-Fungible Tokens, or NFTs, impact value and the future of all things digital? How are they different from–and similar to–blockchain? Jaime Schwarz joins Russ White and Tom Ammon to talk about what NFTs are, how they work, and how they might impact the future.

Hedge 262: Stealthy BGP Attacks


 
Many providers count on detection in the global routing table to discover and counter BGP route hijacks. What if there were a kind of BGP hijack that cannot be detected using current mechanisms? Henry Birge-Lee joins Tom Ammon and Russ White to discuss a kind of stealthy BGP attack that avoids normal detection, and how we can resolve these attacks.

Hedge 261: The NTIA, Spectrum, and Broadband
