We even boarded a 70-person survival vessel that is unsinkable , and which is used in an emergency in the very unlikely event that our research vessel , the Nathaniel B. Palmer ( NBP ) started to sink . There are several management protocols that are used to both in-band and OOB to gather or provide information to the management applications . The Link Layer OAM provides management and troubleshooting of a single link between two Ethernet interfaces , which may be interconnected through Ethernet or an emulated Ethernet connection such as Ethernet over SONET or Ethernet over MPLS . This field course is taught at the Cranberry Lake Biological Station , and includes a survey of vegetation sampling methods , analysis of ecological data and an independent research project . Rooted in data from the Computing Research Association ( CRA ) , the article takes a relatively unsophisticated view of the trends in the pipeline for IT workers .
