Goals and objectives Project(s):Service OAM MIB Purpose of the contribution: Status update of the Service OAM MIB project Abstract: The SOAM MIB project continued work on the FM/TC and PM MIBs. Reviewed and incorporated SB comment for the FM/TC MIBs. Motion:Yes, four motions: two approved drafts, one to initiate a straw ballot and one to initiate a letter ballot
SOAM MIB Status Beijing, China, October 2010 Steve Mood Omnitron Sytems
History • Ad Hoc was created during the 2009 4Q meeting • Project committee was created during the 2010 Q1 meeting • FM/TC MIBs were submitted to Straw Ballot during the 2010 Q2 meeting • FM/TC MIBs were submitted to a second Straw Ballot during the 2010 Q3 meeting • FM/TC MIB to letter ballot meeting and PM MIB to straw ballot during the 2010 Q4 meeting
Original Scope of the Project • A project in the Management Area • Guiding principle • Keep the scope of the project small • Concentrate on SOAM PM and extensions needed for SOAM FM • Ensure the project provides needed functionality and is small enough to be completed in a reasonable amount of time • Documents • A document containing an SNMP MIB for configuring and monitoring SOAM PM capabilities in a Carrier Ethernet environment. • A document containing an SNMP MIB that includes the extensions needed to the IEEE CFM MIBs for the new functionality described in the SOAM FM document. • As a stretch goal, produce a document that includes a YANG model for NETCONF using the same source material used to create the SNMP MIBs for both PM and the FM extensions.
Rationale • Creating an SNMP MIB would be beneficial • Help interoperability between vendor implementations • Allow network operators the freedom to move away from NE-EMS single vendor solutions • One NMS or EMS vendor can interoperate with multiple vendor NEs • Provide a baseline of functionality that supports FM & PM Implementation Agreements (IA)
Quarterly Status • 14 Conference Calls were held during the last quarter • Participation was good. Thanks for those who helped this work along:
Quarterly Status, cont. • Large part of quarterly meetings covered the Performance Monitoring (PM) MIB • MIB was written • MIB was reviewed and updated • Reviewed Straw Ballot Comments for Fault Management (FM) MIB (SB #2) • All the SB comments were reviewed and resolved • Received feedback from the MIB Doctors and their changes have been incorporated into MIB • Started work on YANG model for NETCONF
SOAM MIB Project Timeline/Schedule • 1Q 2010: Project Launch • 2Q 2010: FM/TC MIB went to SB #1 • 3Q 2010: FM/TC MIB went to SB #2 • 4Q 2010: Move FM/TC MIB for LB, PM MIB for SB #1 • 1Q 2011: Move PM MIB for SB #2 (LB?), YANG FM model for SB #1 • 2Q 2011: Move PM MIB to LB, YANG FM model for SB #2, YANG PM model for SB #1 • 3Q 2011: Move YANG FM model for LB • 4Q 2011: Move YANG PM model for LB
FM MIB SB #2 Results • SB #2 Results • 16 Yes votes, 5 Yes with comments, 1 No with comments, 5 Abstains • 36 comments were received from 5 companies • SB #1 Results (last quarter) • 11 Yes, 5 Yes w/comments, 2 No w/comments, 5 abstains • 104 comments were received from 8 companies • SB comments incorporated into FM MIB • Consolidated comments • Updated FM/TC MIB posted
PM MIB Status • The PM MIB was reviewed and completed during the quarter • Global configuration area • DM (Delay Measurement) configuration, current statistic table, and historic statistic table • LM (Loss Measurement) configuration, current statistic table, and historic statistic table • Notification section: containing state alarms and threshold crossing notifications • Conformance & compliance section • Compiled successfully with MG-Soft and LIBSMI • To be submitted to MIB Doctors next quarter
PM MIB Open Item – History table index • Method 1: Most of the standard IETF MIBs have a fixed indexing structure where index 1 is the most recently completed measurement interval. • With 15 minutes intervals in 24 hours would result in index values 1..96 • Method 2: Index starts at 1 but increases overtime, so that the youngest completed measurement interval is the largest index number • Creates a “sliding window” of valid indexes. • With 15 minute intervals in 24 hours would result in index values (x)..(x+95) in a 24 hour period • Comments? smood@omnitron-systems.com
History table index - Pros and Cons • Method 1 (fixed index) • Pros • Supported by standard IETF MIBs: DS1 (RFC2495/3895), DS3 (RFC2496/3896), SONET (RFC 3592), ADSL (RFC2662), HDLS2 (RFC4319) MIBs and RFC 2493/3593/3705 (HC-PerfHist-TC-MIB) • Common method implemented with history tables • Cons • Implementation of OSS very complicated, as a given index refers to different data at different points in time. It is very hard to ensure there are no race conditions when accessing multiple objects. • Many OSS/NMS do not get this right
History table index - Pros and Cons • Method 2 (sliding index) • Pros • Simplifies OSS design • Reduces data integrity problem of when is the data valid in a particular row • Supported by some proprietary MIBs, such as Cisco IP-SLA (RTTMON) MIB, which is widely used • Cons • Not generally supported by IETF MIBs
