Overview ¶
Design: (none -- research/analysis tool)
Analyzes AS_PATH suffix sharing across MRT dumps to determine whether a reversed trie would be effective for AS_PATH dedup.
Measures: unique full paths, unique suffixes at each depth, trie node count, and the compression ratio vs naive per-path storage.
Output: JSON to stdout, human summary to stderr.
Design: (none -- research/analysis tool)
Analyzes MRT dumps for BGP attribute repetition patterns to guide caching optimization decisions. Measures per-attribute uniqueness, bundle dedup rates, temporal locality (consecutive hit rates), and per-peer community extraction.
Output: JSON to stdout, human summary to stderr.
Design: (none -- research/analysis tool)
Analyzes MRT dumps to generate per-ASN community defaults. Identifies which communities appear in nearly every route from a given ASN, enabling pre-configured caching where defaults are assumed present and only exceptions (absences) need encoding.
Output: YAML or JSON with per-ASN defaults and savings estimates.
Design: (none -- research/analysis tool)
Counts BGP attributes per route to produce a distribution table. Shows how many routes have N attributes -- useful for understanding attribute set complexity in real routing tables.
Design: (none -- research/analysis tool)
Analyzes MRT BGP4MP dumps to measure UPDATE message density: how many NLRIs per UPDATE, and how many UPDATEs per second.
This data directly informs per-peer channel sizing for the forward pool: if most UPDATEs carry 1 NLRI, the channel absorbs updates not prefixes. The per-second distribution reveals what "burst" means in production.
Design: (none -- research/analysis tool)
Download MRT RIB dumps and BGP4MP updates from RIPE RIS and RouteViews. Replaces test/internet/download.sh with a Go implementation.
Design: (none -- research/analysis tool)
Dumps MRT records as BGP UPDATE hex, one per line. Useful for piping into ze bgp decode or other analysis tools.
Design: (none -- research/analysis tool)
Shared MRT parsing helpers for ze-analyze subcommands. Provides constants, file opening, record iteration, and wire format helpers.
