Standards Bodies
List of standards bodies in which Extreme Networks® is actively engaged in order to create, develop, publish and promote standards.
IEEE 802
The IEEE 802 LAN/MAN Standards Committee (LMSC)
maintains and develops standards related to local and metropolitan
area networking. The principle groups with 802 for Ethernet are the 802.1
HILI and 802.3 LAN/MAN standards committees. Other 802 active committees
include 802.11 Wireless. Extreme is actively
participating in all of these IEEE committees. IEEE 802 committee holds
3 plenary meetings annually and the specific committees generally hold
interim meeting in between each of the plenary. A detailed description
of the LMSC organization, its charter, history and information on meetings
is contained in this overview document 802overview.pdf.

Downloads of standards and documents are available six months after publication
in PDF format at the "GetIEEE802" web site" http://standards.ieee.org/getieee802/.
IEEE 802.3 Committee
The IEEE 802.3 Working Group develops standards for CSMA/CD (Ethernet)
based LANs. Technologies that have been added to the standard over the
years include Ethernet 10Base-2, 10BaseT, FastEthernet, 100Base-T, Gigabit
Ethernet, 10 Gigabit Ethernet. Following the successful conclusion of
the 10Gigabit Ethernet project 802.3ae last year the remaining active
projects 802.3ah Ethernet in the First Mile.
Other projects active in 802.3 are 802.3af - DTE power, 802.3aj a maintenance
project (to clean up the 802.3 standard as a whole and web site provides
direct links to all of these project.
IEEE 802.3ah project, Ethernet in the First Mile
This project has developed a set of standards to enable Ethernet deployment
over fiber optic cable and voice grade copper in the Telecom access network.
The EFM Task Force is has established a set of mechanisms for Operations
Administration and Maintenance (OAM) to enhance the remote management
capabilities of Ethernet equipment in the access network and used as Customer
Premise Equipment (CPE). For more information go to the IEEE P802.3ah
web site. Additionally Extreme is a founding member of the Ethernet in
the First Mile Alliance see more on the Industry Associations page.

Extreme continues its active participation in the IEEE as part of IEEE
P802.3an 10Gig-Base-T, P802.3aq 10Gig LRM Long Reach Multimode and the
P802.3as Frame Format Expansion working group
Extreme has contributed significantly to the IEEE over the past 7 years
from the recent 10 Gigabit Ethernet, to 1 Gigabit and 100MB Fast Ethernet,
Extreme has been a key technical contributor to the IEEE since the early
1990's.
IEEE 802.3ae (10 Gigabit Ethernet) - Ratified
and now part of 802.3
Supplement to CSMA/CD Access Method & Physical Layer Specifications
- Media Access Control (MAC) Parameters, Physical Layer, and Management
Parameters for 10 Gb/s Operation.
IEEE 802.3z (Gigabit Ethernet) - Ratified and now part of 802.3
An IEEE extension of the 802.3 standard, to address Gigabit Ethernet (1,000
Mb/s). It includes specifications for media access control (MAC) parameters,
as well as physical layer, repeater, and management parameters for Gigabit
Ethernet.
IEEE 802.3u (Fast Ethernet) - Ratified and now part of 802.3
Supplement to Carrier Sense Multiple Access with Collision Detection (CSMA/CD)
Access Method and Physical Layer Specifications: Media Access Control
(MAC) Parameters, Physical Layer, Medium Attachment, and Repeater for
100 Mb/s Operation, Type 100 Base-T.
IEEE 802.1 High Level Interface (HILI) Committee
The IEEE 802.1 Working Group is chartered to concern itself with and develop
standards and recommended practices for higher level interfaces to the
802 LAN/MAN architecture, internetworking among 802 LANs, MANs and other
wide area networks. The HILI group is responsible for Bridging operations
and protocols, overall network management, and protocol layers above the
MAC & LLC layers. This is committee is primarily concerned with the
architecture of Ethernet L2 bridged networks, and standardizes protocols
and concepts including MAC and VLAN addressing, Ethernet packet formats,
control protocols (like Bridge Control Protocols, BPDUs).
Recently the group has turned its attention to protocols and procedures
designed to help Service Providers use Ethernet in the public network.
The IEEE 802.1ad Provider Bridge project is focused on standardizing mechanisms
to improve the scalability and provisioning capabilities of Ethernet networks.
Areas of consideration are standard mechanisms for VLAN tag stacking,
standard procedures for handling control protocols (such as BPDU or LACP
packets) and other architectural issues related to the use of Ethernet
in the public metro and access networks.

IETF
The Internet Engineering Task Force (IETF) is a large open international
community of network designers, operators, vendors, and researchers concerned
with the evolution of the Internet architecture and the smooth operation
of the Internet. It is open to any interested individual.
The actual technical work of the IETF is done in its working groups,
which are organized by topic into several areas (e.g., routing, transport,
security, etc.). Much of the work is handled via mailing lists. The IETF
holds meetings three times per year. Extreme has recently published an
Informational RFC on Ethernet Automatic Protection Switching (EAPS) technology
IETFRFC 3619 in an attempt to define an open and widely deployed technology
for improving the resiliency of Ethernet Ring-based networks.
Here are a few of the standards that Extreme Networks has helped shape as part of the IETF:

The Trusted Computing Group (TCG) is an industry standards body, comprised
of computer and device manufacturers, software vendors, and others with
a stake in enhancing the security of the computing environment across
multiple platforms and devices. Extreme is actively participating in the
Trusted Network Connect standard, which will bring open, multi-vendor
solutions to the area of host integrity checking, giving IT administrators
tools for gaining the upper hand on today's rapidly-spreading security
threats.
