Basic BGP Data Plane Convergence Benchmarking

This draft focuses on benchmarking BGP data plane convergence, examining both IPv4 and IPv6 implementations. It outlines methodologies including various test cases assessing basic BGP convergence functionalities per RFC 4271. Key aspects covered include the impact of peer numbers, route processing, policy configurations, and traffic characteristics on convergence times. Different scenarios are explored, such as iBGP and eBGP convergence events, along with specific factors like link failures and BGP resets. Community feedback is sought to refine the testing framework.

  1. Basic BGP Data Plane Convergence Benchmarking draft-papneja-bgp-basic-dp-convergence-00 • Rajiv Papneja

  2. Background and Current Status • Terminology for Benchmarking BGP Device Convergence in the (RFC 4098) / June 2005 • Methodology draft focusing on the BGP Data Plane convergence has been posted • http://tools.ietf.org/html/draft-papneja-bgp-basic-dp-convergence-00 • Team • Rajiv Papneja, Susan Hares, Bhavani Parise, Mohan Nanduri, Jay Karthik, & Eric Brendel

  3. Scope of the Draft • BGP Data plane FIB convergence for both IPv4 and IPv6 • Limited to Basic BGP convergence (RFC 4271 functionality with Multi-Protocol BGP (MP-BGP) for IPv6) • BGP Failure/Convergence Events • Considers dependencies on factors impacting convergence: • Number of peers, • Number of routes/peers • Policy Processing/Reconfiguration • Data Traffic characterization – offered load • Various test cases that covers iBGP, eBGP and failure convergence events • Topologies – Several 3 node, and 4 node setups

  4. Test Cases • Basic Convergence Tests • RIB-IN Convergence • RIB-OUT Convergence • eBGP Convergence • iBGP Convergence • eBGP Multihop Convergence • BGP Failure/Convergence Events • Physical Link Failure on DUT End • Physical Link Failure on Remote/Emulator End • ECMP Link Failure on DUT End

  5. Test Cases • BGP Adjacency Failure (Non-Physical Link Failure) on Emulator • BGP Hard Reset Test cases • BGP Non-Recovering Hard Reset Event on DUT • BGP Soft Reset • BGP Route Withdrawal Convergence Time • BGP Path Attribute Change Convergence Time • BGP Graceful Restart Convergence Time 26

  6. Next Steps • Solicit input from the community • Feedback and comments from the group on the test cases • Request to accept the document as WG item
