Hi,

This is a survey to implementers (equipment vendors) and to service providers in order to assist in progressing draft-ietf-l2vpn-vpws-iw-oam-01.txt, "OAM Procedures for VPWS Interworking". Since this draft has existed for some time and given the technologies involved, we are assuming that vendors would have implemented what the market needs by this time and that service providers would have deployed the technology that satisfies their needs. The goal of the survey is to enable focusing on the technologies of interest going forward.

Please respond to the survey below by replying to me only at [email-masked]. Your response will remain confidential. As a co-chair of the l2vpn WG, I will present the results in number of implementations and in number of users without mentioning company names. You may include comments in your response, if needed, following each question. This survey will close in 2 weeks on Tuesday March 22, 2011. Your response is appreciated by the survey closure date.

Are you an equipment vendor? (Y/N)
Are you a service provider? (Y/N)
What is your company name? Needed for authenticity. Please, remember this will remain confidential and will not be included in the published survey results

Has the VPWS OAM Interworking implementation included any the of following VPWS types and corresponding OAM interworking models as stated in the introduction section of draft-ietf-l2vpn-vpws-iw-oam-01.txt and in Table 1 of that document:

     1. VPWS with heterogeneous ACs of ATM and FR types, and in which
        the PW type is ATM or FR. In this case, FR-ATM service
        interworking [FRF8.2] is performed in PE1 (or PE2) and a FR (or
        ATM) PW is extended to the remote PE. This VPWS type will be
        referred to as "FR-ATM Interworking VPWS". (Y/N)?

    In addition, please indicate which PW type is supported:
         a. ATM cell mode PW. (Y/N)?
        b. ATM AAL5 PDU/SDU mode PW. If one of the two types is supported, state which one is supported. (Y/N)?
        c. FR PW. (Y/N)?

     2. VPWS with heterogeneous ACs of ATM, FR, and Ethernet types, and
        in which the PW type is Ethernet. This VPWS type will be
        referred to as "Ethernet Interworking VPWS". (Y/N)?

     3. VPWS with heterogeneous ACs of ATM, FR, and Ethernet types, and
        in which the PW type is IP [ARP-Mediation]. This VPWS type will
        be referred to as "IP Interworking VPWS". (Y/N)?

Nabil
