Why Network Standards?
• Ensure proper interoperability
• Open specification leads to more
competition and lower cost to the end-user
• Enables mixing and matching between
vendor equipment and not being locked up
with one vendor

802.3ae (cont.)
Compromise Decision:
 Extend the 802.3 protocol to an operating speed
of 10 Gb/s and to expand the Ethernet
application space to include WAN links. This is
to be accomplished by having:
 One common MAC
 Two PHYs:
 A PHY for LANs at 10 Gbps
 A PHY for WANs at 9.58464 Gbps
(compatible with SONET OC-192)

 Ethernet tries to achieve what ATM failed
 Unifying the LAN and WAN environment
 Opens the door for Ethernet Rings in MANs and
WANs along with SONET Rings
 IEEE 802.17

Isochronous
Asynchronous
– Occurs on regular
boundaries (125us)
– Are unacknowledged
– Occur “just in time”
– Broadcast to all channels
– Have BW reserved
– Guaranteed timing
– Never retry Late data is
useless
– Occurs on a “First come, first
served” basis
– Are acknowledged
– Occurs “as fast as possible”
– Are addressed explicitly
– Use available BW
– Guaranteed delivery
– Reliability of data transfer
