Tool to "replay" incremental refresh packets from PCAP files #10

Open iamolever opened 7 years ago

1) Open file with incremental refresh feed; 2) Jump to incremental packet; 3) … and then manual next commands; Probably also more complex logic with added snapshot feed (to have initial state in test case).

Console version is OK. CMD tool is OK (as first versions)

Hi, can I help with this enhancement? I am familiar with pcap and have some experience. Could you please share more details?

iamolever commented 5 years ago

Ok, do know already the concept of MDP3?https://www.cmegroup.com/confluence/display/EPICSANDBOX/CME+MDP+3.0+Market+Data At least idea of synchronization from snapshots packets, and then refresh from incremental packets?

pkarneliuk commented 5 years ago

snapshots and incremental updates are clear. Where are traffic examples with SBE payload in pcap format (incremental refresh feed)? I mean something like "dist/pcap/311_AX.bin". I see some .zip archives in java-cme-mdp3-handler/mbp-only/src/cucumber/sim/data is it applicable?. Which incremental packet should be replayed? What API consumes payload from selected frames? Which CLI is expected for the tool?
