Chapter 55.3.2 Analyzing the Discovery Data Sample TraceUse the File, Open... command to open the file, discoveryTrace.pkt (see Section 5.3 forits location).The sample file contains a sequence of RTPS packets that illustrate the protocol whentwo RTI Data Distribution Service applications use best-effort communications to send/receive data.This scenario involves two hosts, each running one RTI Data Distribution Service application.❏ Host 1 (10.10.100.2) is running an RTI Data Distribution Service publishing application,App1.❏ Host 2 (10.10.50.247) is running an RTI Data Distribution Service subscribingapplication, App2.❏ Both applications have a maximum participant index of 1 and have each other intheir initial_peer_list.❏ All QoS are at default values, including the use of automatic discovery via thedefault UDPv4 transport.Wireshark was set up to start capturing packets before either application was started. Thepublishing application was started first, followed (about 6 seconds later) by the subscribingapplication. Figure 5.9 shows the packets captured by Wireshark.Let’s walk through the RTPS packets to understand what occurred in this sequence.Table 5.5 describes what happened (non-RTPS packets are omitted). In the table, theterm “meta DATA” refers to DATA packets containing meta (discovery) data (asopposed to user data).5-16
