Updated: 5 days ago

RFCsWeLove is a meetup organized by the India Internet Engineering Society (IIESoc). The last RFCsWeLove meetup was on 24th Sept 2022 (Saturday) with a focus on Hot topics that were discussed in the Routing Area during the last IETF meeting.

Date: 24 Sept 2022, Saturday

Time: 11 am - 1 pm


The agenda for the session was -


  • Introduction & Welcome - Dhruv

  • Intent - aware Interdomain Routing - Srihari Sangli

  • MPLS Network Action (MNA) - Vishnu Pavan Beeram

[Slides]





Intent - aware Interdomain Routing


The evolving network requirements (e.g. 5G, native cloud) in a multi-domain network requires the establishment of paths that span multiple domains or AS's while maintaining specific transport characteristics or intent (e.g. bandwidth, latency). There is also a need to provide flexible, scalable, and reliable end-to-end connectivity for multiple services across the network domains. This session will go over the scope, set of use-cases and requirements for a distributed routing based solution to establish end-to-end intent-aware paths spanning multi-domain packet networks using BGP. This session will also introduce various approaches that are being worked on in the IDR WG at IETF.


Srihari Sangli is a Distinguished Engineer at Juniper Networks. He has over 25 years of experience in the network industry and has worked for Cisco Systems, Procket Networks, and at present Juniper Networks. His current areas of interest are Network Slicing, Segment Routing, intent-aware routing, etc. He has co-authored a few RFCs, internet drafts, and a book on BGP. He is based out of Bangalore, and spends his free time with his family.





MPLS Network Action (MNA)


The MPLS architecture [RFC3031] enables packet forwarding through a network without requiring the intermediate routers to do any inspection/analysis of the packet payload's network layer header. Several use-cases [draft-ietf-mpls-mna-usecases] and applications have recently emerged which require intermediate MPLS routers to make forwarding decisions based on inspection of the network layer header, or some other ancillary data encapsulated in the packet.


MPLS Network Actions (MNA) [draft-ietf-mpls-mna-fwk] refers to the technologies used to indicate network actions for MPLS packets and to transfer data needed for these actions. In this talk, we will cover the use-cases, requirements and architecture for MNA and also discuss a solution approach that addresses these requirements.


Vishnu Pavan Beeram is a Distinguished Engineer at Juniper Networks. He has 20+ years of Software Development experience working on a variety of switching and routing platforms. As part of Juniper’s Routing Protocols Development team, his current focus is on analytics, containerized applications and customer-focused innovations in the IP/MPLS Traffic Engineering space. He is a regular contributor at the IETF and currently serves as a co-chair of the IETF’s TEAS Working Group. Prior to joining Juniper Networks, he spent 7.5 years developing control plane solutions in the optical domain for ADVA Optical Networking. Prior to that, he was with AVICI systems for about 4.5 years developing various MPLS-TE features. And prior to that, he had stints doing maintenance work at Lucent/Ascend and 3COM.

He has a Master’s in Engineering Management from George Washington University and a Bachelor’s in Computer Science & Engineering from Sri Venkateswara University.
