Towards a traffic map of the Internet Connecting the dots between popular services and users: Connecting the dots between popular services and users

The impact of Internet phenomena depends on how they impact users, but researchers lack visibility into how to translate Internet events into their impact. Distressingly, the research community seems to have lost hope of obtaining this information without relying on privileged viewpoints. We argue for optimism thanks to new network measurement methods and changes in Internet structure which make it possible to construct an "Internet traffic map". This map would identify the locations of users and major services, the paths between them, and the relative activity levels routed along these paths. We sketch our vision for the map, detail new measurement ideas for map construction, and identify key challenges that the research community should tackle. The realization of an Internet traffic map will be an Internet-scale research effort with Internet-scale impacts that reach far beyond the research community, and so we hope our fellow researchers are excited to join us in addressing this challenge

Abnormal location of papilla of Vater: a cadaveric study

We report a case of a male cadaver aged 72 years with an ectopic location of the papilla of Vater. The ectopic papilla was situated at the supero-posterior border of the 3rd portion of the duodenum at a distance of 0.9 cm from the limit of the 2nd and 3rd portions of the duodenum. The frequency of this anomaly fluctuates between 0 and 11.83% and when the papilla is located distal to its usual position the usual location is in the proximal 2 cm of the 3rd part of the duodenum. We refer to the possible difference in the papilla’s location between patients and cadavers and call attention to the differential diagnosis with spontaneous or surgical fistulae
