As you already know, you can search pcapr by entering various search criteria. This allows you to quickly find pcaps that you need. What if you wanted a pcap that has a specific protocol field in it? Maybe a SIP pcap with the WWW-Authenticate header or an SMB/DCERPC pcap with the winreg protocol? Well, we indexed the unique protocol fields across all of the pcaps so you can find what you are looking for. In addition, we can now compare the coverage of fields (similar to code coverage) for a particular protocol against Wireshark's master index. This automatically tells you what kind of pcaps you can upload to help out the community.
