AMES is 4-connected, i.e. four network connections will go down        if the IMP fails.  Is there some aspiration that IMPs should be        no more than three connected?    2.  The seven IMPS in the Washington area are arranged into a loop.        This guarantees that local communication can take place even if        one connection fails, and is probably a worthwhile preparation        for area routing.  On the other hand, for example, a break        between MIT-IPC and MIT-MAC will require them to communicate        through a 12-hop path through Washington.  This can be remedied        by a short (inexpensive) connection between Harvard and Lincoln        Labs.  Is there a plan to pull the Boston area, the San        Francisco area, and the Los Angeles area into loops like the        Washington area?
