Episode 15 – Characteristics of a Well Run Network

In episode 15, Pete Welcher and Chris Kane join us to talk about what exactly characterizes a well run network. Is it great documentation? Is it consistent application of best practices? Maybe it’s process and procedure? Join our guests, and the decades of experience they bring, as they sit around the virtual roundtable to share their thoughts on the topic.

Show Notes

Design

• Keep it simple. Just because you can, doesn’t mean you should
• Complexity is not just a networking attribute, it’s an overall system attribute
• Proper design leads to simplicity (most of the time)
• What technologies are simple? How do you recognize complexity? Is vendor lock-in one indicator? Network management software / API lock-in another growing one?
• There are some pretty simple campus/user, datacenter, Internet Edge, and WAN approaches Big organizations can handle and may need a bit more complexity — or not
• Modularity- too many moving parts that have to work together = complex

Operations

• Transparent Network. It just works
• Able to easily implement changes
• Agnostic to both today’s needs and flexible to absorb tomorrow’s needs
• Up-to-date diagrams and documentation matter
  • Organized around OSI layers
  • Documented naming conventions with fixed fields
  • MTTR e.g. from NetMRI and Continue reading

History Of Networking – Donnie Savage – EIGRP

Donnie Savage joins Network Collective to talk about his role in the history of EIGRP. From its early implementations to moving this formerly fully proprietary protocol through the IETF, Donnie has played a significant role in guiding EIGRP to where it is today.

Episode 14 – Digging Deep into the IS-IS Routing Protocol

In a return to our routing protocol series, Russ White and Nick Russo join Network Collective to talk about some of the intricacies of the IS-IS routing protocol. While not usually found in enterprises, Service Providers have used IS-IS as the underlay to their MPLS networks and it is starting to make an appearance as the underlay to several newer enterprise technologies. If you’ve been curious about how it works, and how it is different than what you use today, this show is for you.

Show Notes

• IS-IS Characteristics
  • IS-IS is a graph
    • Vertices, edges, link types, cost
    • Uses Dijkstra’s algorithm
    • Based on Type Link Value protocol (TLV) instead of fixed type fields which allows IS-IS to be very extensible
    • Similar to OSPF, but the P-node is called the DIS, not the DR, and behaves a bit differently
    • Originally built for host routing
  • Not an IP protocol
    • direct encapsulation to L2, ethertype 0xFEFE
    • Provides some inherent security benefits (very hard to reach in and attack; OSPF solved this with TTL security)
  • QoS over L2VPNs
    • If the EFP is matching IP DSCP for QoS, ISIS may not Continue reading

History Of Networking – Radia Perlman – Spanning Tree

Radia Perlman joins Network Collective to talk about the history of the Spanning Tree Protocol. Love it or hate it, it’s been a fundamental part of every Ethernet network for the past 30 years and isn’t likely to fade away any time soon.

Episode 13 – A Look In The Mirror

In episode 13, the Network Collective hosts go it alone and take an introspective look at the engineering community, warts and all. We dig into topics relating to ego, hero mentality, overconfidence, short memories, and the negative side of the hype cycle.
