PC-S(P)C Requirements and Solution Status CCAMP WG, IETF 71 th Philadelphia Diego Caviglia, Dino Bramanti, Dan Li

Requirements draft-ietf-ccamp-pc-and-sc-reqs-02.txt Data Plane LSP Consistency No Disruption of User Traffic Transfer from Management Plane to Control Plane Transfer from Control Plane to Management Plane (Optional) Synchronization of state among nodes during conversion Support of Soft Permanent Connections Failure of Transfer

Requirements Status The Draft is stable; Dave McDysan from Verizon joined the authors; Proposal to go for Last Call

Solution ID First version of the solution ( draft-caviglia-ccamp-pc-spc- grsvpte-ext-02 ) ID is Active; New authors have joined:  Snigdho Bardalai & Shan Zhu (Fujitsu)  Igor Bryskin (ADVA Optical Networking) New section (optional) about path Discovery has added Review of failure scenarios and bit&bytes

Solution procedure Outline Path_migration (Admin Flag set) XC semi- migrated Path_migration (Admin Flag set) Path_migration (Admin Flag set) Path_migration (Admin Flag set) XC semi- migrated Resv XC semi- migrated XC- migrated

Solution procedure Outline Path Failure - RollBack Path_migration (Admin Flag set) XC semi- migrated Path_migration (Admin Flag set) Path_migration (Admin Flag set) XC semi- migrated Path_Err-PSR XC rollbacked to NSM State Failure Path_Err-PSR XC rollbacked to NSM State

Solution procedure Outline Resv Failure – RollBack Proposal for new Revision Path_migration (Admin Flag set) XC semi- migrated Path_migration (Admin Flag set) Path_migration (Admin Flag set) Path_migration (Admin Flag set) XC semi- migrated Resv XC semi- migrated XC- migrated Path_Err-PSR XC rollbacked to NSM State ResvErr+Special Flag in ErrorSpec ResvErr+Special Flag in ErrorSpec XC rollbacked to NSM State

Next Step Adopt the ID as WG
