  2. Motivations Networks Evolution - Multi-Layer and Multi-Domain networks - Different user requirements - Delay and Bit Error Ratio (BER) are proposed Present RFCs and Drafts Advantages of This Draft - In Delay: scalability, LSP quality, reference to service acceptance - In BER: LSP quality, reference to service acceptance

  3. Delay: PCE PCE PCE Methodologies (1) T S D T0, a time when the path computation is attempted T1, a time when the LSP setup is attempted T2, a time when the optimal path computation result returns T3, a time when the LSP confirm message of successful reservation returns

  4. BER: Methodologies (2) BER Evaluation PCE PCE PCE S D BER is computed in the destination node combining the corresponding physical parameter information

  5. Protocol Extension Requirements Regarding Delay: - New objects that include time stamp need to be added in corresponding protocols Regarding BER: -A new object that includes network physical parameters needs to be added in signaling protocol in order to collect the physical information of nodes and links

  6. Next Steps Any Comments?
