Subject: IPv6: The New IP - 08/20/1997 - Presented by BLU.ORG & the
Greater Boston ISIG
 
In conjunction with the Greater Boston Internet SIG, Boston Linux &
Unix [BLU.ORG] presents at talk on:
 
  IPv6: The New IP - A Technical Overview

Who: Jack McCann <mccann at zk3.dec.com>
Date: 20 August 1997, Wednesday
Time: 7:00 p.m.
Place: M.I.T. -- Building 3 - Room 133
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^                      
 
Digital Equipment Corporation has a team working on implementing
IPv6. Jack McCann, a Project Leader and development member of this
team will be giving us a technical overview of IPv6, along with a
discussion of the problems that IPv6 addresses and when it is expected
to be widely deployed.

IPv6 Implementations are being developed for many different host
operating systems and routers. These include 4.4-lite BSD, AIX,
BS2000/OSD, BSDI/OS, Digital UNIX, embedded operating systems, WIN95,
DOS, Windows, FreeBSD, HP-UX, Linux, NetBSD, Novell, [Image] NTHU,
SCO, Solaris 2, Streams, and 3com, BayNetworks, cisco, Ipsilon, Merit
(routing protocols), and Telebit routers.
  
    We are holding this as a joint meeting with the Greater Boston
			    Internet SIG.
 

********************
What is IPv6?

(Taken from the ``Linux IPv6 FAQ/HOWTO'' at
http://www.panix.com/~ulmo/linux/ipv6/ )

IP version 6 (IPv6) is a new version of the Internet Protocol, designed as a
successor to IP version 4 (IPv4) [RFC-791].

The changes from IPv4 to IPv6 fall primarily into the following categories:

   * Expanded Addressing Capabilities

     IPv6 increases the IP address size from 32 bits to 128 bits, to support
     more levels of addressing hierarchy, a much greater number of
     addressable nodes, and simpler auto-configuration of addresses. The
     scalability of multicast routing is improved by adding a 'scope' field
     to multicast addresses. And a new type of address called an 'anycast
     address' is defined, used to send a packet to any one of a group of
     nodes.

   * Header Format Simplification
     Some IPv4 header fields have been dropped or made optional, to reduce
     the common-case processing cost of packet handling and to limit the
     bandwidth cost of the IPv6 header.

   * Improved Support for Extensions and Options

     Changes in the way IP header options are encoded allows for more
     efficient forwarding, less stringent limits on the length of options,
     and greater flexibility for introducing new options in the future.

   * Flow Labeling Capability

     A new capability is added to enable the labeling of packets belonging
     to particular traffic 'flows' for which the sender requests special
     handling, such as non-default quality of service or 'real-time'
     service.

   * Authentication and Privacy Capabilities

Extensions to support authentication, data integrity, and (optional)
data confidentiality are specified for IPv6.
