Multiple instances of dns-replay-client can work coordinately to replay large query stream with dns-replay-controller.ĭistribute DNS query stream and to queriers (dns-replay-client).Ĭhange DNS queries in a network trace file and generate binary input for dns-replay-.ĭns-replay-proxy manipulates packet addresses to emulate DNS hierarchy in LDplayer.

Optionally it can log the latency for each query, or the timing for each query and response. LDplayer consists of a number of components.ĭns-replay-client replays DNS queries against a real DNS server with correct timing.

Proceedings of the ACM Internet Measurement Conference (Boston, Massachusetts, USA, Oct. We describe and evaluate LDplayer in the following paper: It can emulate DNS hierarchy efficiently using minimal commodity Levels of DNS hierarchy, large query rates, and diverse query sources. LDplayer is a configurable, general-purpose DNS trace replay and modification systemĭNS experiments at scale in several dimensions: many zones, numerous
