3. IEEE 802.3 CFI Vancouver CA March 2009 March 2009 3 Why Are We Here To measure the interest in forming an 802.3 Study Group to investigate: –Providing support in 802.3 for IEEE 802.1AS by Providing an accurate indication of the transmission and reception initiation times of certain packets Not to –Fully explore the problem –Debate strengths and weaknesses of solutions –Chose any one solution –Write a PAR and 5 Criteria –Write a standard or specification

4. IEEE 802.3 CFI Vancouver CA March 2009 March 2009 4 Why now? Work in this area has been ongoing since July of 2004 with the 802.3 Residential Ethernet SG RESG work was transferred to 802.1 in 2005 802.1 is working on a suite of Audio/Video Bridging protocols 802.1AS Timing and Synchronization is what 802.3 is being asked to support An 802.3 standard isnt necessarily needed to support 802.1AS, but it would be good practice to have an 802.3 standard that does!

5. IEEE 802.3 CFI Vancouver CA March 2009 March 2009 5 Why now? Pointers to RESG work
