Testing Instructions

This folder contains a tcpdump trace that can be used to manually check the correctness of ndndump.

Test Cases / Trace File Description

1. NDNLPv2 NACK

Trace file: nack.pcap

Trace summary: Six IPv4 UDP packets, carrying NDN interests and NACK packets. Twelve IPv4 TCP packets, carrying NDN interests and NACK packets.

Expected result of the capture:

• 3 NDN interests are captured with UDP tunnel type.

• 3 NACKs are captured with UDP tunnel type and the NACK reasons:

  • Congestion
  • Duplicate
  • None

• 3 NDN interests are captured with TCP tunnel type.

• 4 NACKs are captured with TCP tunnel type and the NACK reasons:

  • Congestion
  • Duplicate
  • None
  • None

2. LINUX_SLL link-type

Trace file: LINUXSLL-udp4.pcap LINUXSLL-udp6.pcap LINUXSLL-tcp4.pcap LINUXSLL-tcp6.pcap

These traces are captured inside an OpenVZ container which uses LINUX_SLL (Linux cooked) link-type.

Expected result: Some Interests and Data should be displayed from udp4 and tcp4 traces. Currently nothing is displayed from udp6 and tcp6 traces because ndndump lacks IPv6 support until Feature 3861.
