Summary of Segment Routing: the stuff marketing doesn’t talk about

00:00:00 - 00:30:00

This video discusses the practical considerations of implementing segment routing, including label management, controller care and feeding, and traffic protection. It also provides an overview of the different segment routing types and their implications for traffic engineering.

• 00:00:00 This talk discusses some of the practical considerations involved in implementing segment routing, such as label management, controller care and feeding, and traffic protection. It also provides an overview of the different segment routing types and their implications for traffic engineering.
• 00:05:00 This video discusses the concept of segment routing, and how it affects global SIDs and binding SIDS. It also covers how to configure segment routing for optimal performance.
• 00:10:00 Segment routing is a way to manage traffic in a network by controlling the path it takes. It can be used to enforce specific traffic flows or to distribute traffic across multiple nodes. It can be used in conjunction with anycast SIDs and prefix IDs, and requires careful consideration of hardware capabilities and entropy sources.
• 00:15:00 This video discusses the coexistence of segment routing and RSVP in a network. It explains the various considerations for migrating from RSVP to segment routing, such as static bandwidth partitioning, RSVP admission control, and centralized capacity management.
• 00:20:00 Segment routing is a technique used to route traffic in a network, typically by assigning individual traffic flows to specific physical networks. In order to do this, a controller must have visibility into network utilization and traffic loads, and be able to proactively move traffic or deal with failures. To achieve this, streaming telemetry must be used to collect per-label traffic statistics.
• 00:25:00 Segment routing is a topic that marketing typically doesn't talk about, but is essential for understanding how traffic is routed on a modern network. There are three traffic engineering protocols discussed in the video: BGP, PSEP, and PC-based path placement. BGP is a useful protocol for ecmp dense environments, PSEP provides for segment routing LSP configuration, and PC-based path placement allows for path placement based on actual capabilities negotiated with a PCE at an ingress node.
• 00:30:00 This video explains the functionality of segment routing, which is a feature of Juniper Networks routers that allows administrators to define label stacks and paths and associate rib entries with these paths, which enables them to build an agent or to do something novel, such as creating a bypass path that is under their control. It also discusses the practical considerations of deploying traffic protection using this technology, including the need for internal development expertise and the need for vendors to provide API's that can be tested and verified. Finally, the presenter mentions that SR is an area of active development, and asks if anyone has any questions.
