Hello Huub, Thanks for this clarification. Can I consider flowing two drafts are different option for implementing APS in MPL-TP? 1) Linear Protection Switching in MPLS-TP draft-zulr-mpls-tp-linear-protection-switching-01.txt 2) MPLS-TP Linear Protection draft-ietf-mpls-tp-linear-protection-03.txt Regards, Saravanan. -----Original Message----- From: Huub van Helvoort [mailto:huubatwork@gmail.com] Sent: Monday, December 27, 2010 2:37 PM To: Saravanan P Cc: mpls-tp@ietf.org Subject: Re: [mpls-tp] Linear Ether APS-g8031 Hello Saravanan, You wrote: > I am implementing Ether APS channel functionality over pseudo wire/LSP > and using BFD for CCM . As per my understanding Liner protection > switching functionality shall be implemented by two standard > IETF(draft-ietf-mpls-tp-linear-protection) and another one is I-TUT (g8031). FYI: G.8031 is the linear protection for Ethernet. G.8131 is linear protection for MPLS-TP, see also http://tools.ietf.org/html/draft-zulr-mpls-tp-linear-protection-switching which is based on G.8131. > CCM functionality would be either y.1731 or BFD but EtherAps should be > g8031 or IETF. The linear protection uses the SF (signal/service fail) as trigger. SF detection can be based on MT-CCM defined in http://tools.ietf.org/html/draft-bhh-mpls-tp-oam-y1731 or on extended BFD. > Is this combination work in field and any one foresee interoperability > issue? The MT-CCM and G.8131 combination has been tested several times by EANTC and is deployed in China by major operators in many nodes. > I don’t see anywhere in requirement document for g8031 as an APS > option on LSP/PW. As I mentioned above look for G.8131, but you will not find that in any requirement document as this is considered a solution of the generic "linear protection requirement".
