     Topic:  Switching LANs, VLANs and ELANs

   Speakers: Debby Goldman and John Garrison from Xylan (http://www.xylan.com)

Main Presentation:

  As many of our members know, there is a revolution brewing in LAN
  technology.  Now that everyone has a PC powerful enough to process graphics,
  the old 10MB Ethernet LAN, which once looked like a high-speed data highway,
  is looking more like the LIE on a Sunday afternoon trip back from the
  Hamptons.  Bandwidth is the issue, and there's only so much to go around.

  One of the current approaches to breaking the bandwidth bottleneck involves
  the use of high-speed switches operating at the MAC, OSI layer 2 level.
  These "switches," implemented in hardware, are used to establish parallel
  paths between LAN users.  This approach has the capability of multiplying
  available bandwidth by an order of magnitude.  It also offers the
  opportunity of implementing a Virtual LAN (VLAN), where membership is
  defined by functional affiliation rather than physical location.

  Our speakers for this month's meeting are Debby Goldman and John Garrison
  from Xylan Corporation, a young firm headquartered in Calabasas, California.
  Xylan is a leading provider of high-bandwidth switching systems that enhance
  the performance of existing LAN's and facilitate migration to next
  generation networking technologies such as ATM.  Our speakers, in their talk
  "VLANs don't work... Unless...,"  will deal with these topics, among others:

    - What exactly is a VLAN?
    - What is an ELAN?
    - How do they differ?
    - What are the benefits of VLANs to business users, LAN administrators,
      and managers?
    - Getting there -- a migration strategy to move from hierarchical
      router-centric LANs to flat, switch-centric LANs.

  In addition to presenting their talk and answering questions, Debby and
  John will be giving away copies of Xylan's new publication, "The Switching
  Book".  This is a very informative, 183-page large-format glossy book that
  covers the general topic of LAN switches and related technologies.  No one
  who is involved with networking -- either directly or indirectly -- who
  wants to understand the new technology should miss this presentation!

  Debby Goldman is the N.Y. Territory Manager for Xylan, and has been selling
  inter-networking solutions in N.Y.C. for seven years.  Before that, she
  managed an inter-networking group for Manufacturer's Hanover, and worked as
  an independent consultant for AT&T, Johnson & Johnson, Bell Labs, and
  DoubleDay Publishing.  John Garrison is a Systems Engineer for Xylan.

                Room Location Specifics:
                   Enter the building at Old Slip.  To get to the South
                   Tower of the complex, you enter the building at Old
                   Slip at the "North Tower" doors.  This entrance is
                   is immediately to the right of the main entrance,
                   towards Water Street.  Go past the guard's desk
                   (mentioning you are heading for Unigroup) to the
                   elevator bank and go to the 13th floor.
                   When you get to the 13th floor, follow the signs leading
                   you to the meeting room.

                   The signs will lead you from the elevator, through a set
                   of doors, then past the cafeteria.  If the entrance
                   doors near the elevator on the 13th floor are locked
                   (may happen after 6pm), call the security desk using the
                   available telephone, and they will radio the guard on
                   the 13th floor to let you in.  After the cafeteria, you
                   see another "lobby" area.  Walk past the cash machines,
                   make a left and look for a sign marking the meeting room.

Unigroup's printed newsletter is sent out to people on our U.S. Mail mailing
list.  The newsletter contains information such as meeting announcements,
technical and non-technical articles and recent UNIX security advisories.
Ross Ziskind is the editor of the Unigroup newsletter.  Keep an eye out for
the next issue.

To keep the newsletter going, the two biggest problems to overcome are:
        a) Volunteers to see that it gets out
        b) Content material

If you have any ideas or can help contribute to our newsletter, please make
them known at our meetings and/or let us know by EMail.  If you know anyone
who has experience in sending out a newsletter, we can always use some good
advice.  Ross can be reached via email to editor@unigroup.org.

We are also looking for an individual who can take over most of the
editorial work for the newsletter as our current editor's time has become
extremely scarce.  All interested parties please notify us immediately.


I hope to see you all at Unigroup's July 1996 meeting...
