 Link-State Advertisements (LSAs) represent pieces of routing information distributed by routers.
-NLSR uses three types of LSAs to distribute routing information:
-Adjacency LSAs which include neighboring node and link information,
-Coordinate LSAs which include a router's hyperbolic coordinates, and
-Name LSAs which include advertised name prefixes reachable through the router.
-All of the LSAs received by the router are maintained by the LSDB module (Section~\ref{sec:lsdb}).

 All three LSA implementations inherit from an LSA Base class, \texttt{Lsa}, which maintains information that is included in each LSA.
 The \texttt{LSA} class contains the following member variables:
 \begin{itemize}
-\item \textbf{Origin Router} - the router that advertised the LSA.
-\item \textbf{Sequence Number} - a number used to indicate the LSAs version as well as its ordering compared to other LSAs received from the same router.
-\item \textbf{Expiration Time Point} - a time point indicating when the LSA is no longer valid.
+\item \textbf{Origin Router} - the router that advertised the LSA. Specifically, this is a name prefix that follows the NLSR convention of router naming.
+\item \textbf{Sequence Number} - a number used to indicate the LSA's version. Because sequence numbers are preserved between NLSR restarts, a higher sequence number also always indicates a \emph{newer} LSA.
+\item \textbf{Expiration Time Point} - a time point indicating when the LSA is no longer valid. This currently is represented as a Unix timestamp (i.e. seconds since Jan 1, 1970).
