  1. DRNINetwork Protection Interaction • Some examples in which one or more faults in DRNI require a change in Network Protection • Some examples in which one or more faults in Network Protection require a change in DRNI • Adds additional ‘external’ protection switching trigger condition(s) to DRNI (from NP) and to NP (from DRNI) • DRNI and NP need to communicate with each other; what is the minimum message set?

  8. B-VLAN Recovery • How to control that active B-VLAN endpoint is moved from node 2 to node 3 for examples in figures 3A, 3B, 4B and 5A? • How to control that DRNI active GW is moved from node 2 to node 3 for examples in figures 4B and 5A?

  9. TESI Protection • How to control that active TESI endpoint is moved from node 2 to node 3 for examples in figures 3A, 3B, 4B and 5A? • How to control that DRNI active GW is moved from node 2 to node 3 for examples in figures 4B and 5A? • How to control that TESI endpoint in node 1 switches from W to P for example in figure 3B?

  10. EC SNC Protection • How to control that active EC SNCP endpoints are moved from node 2 to node 3 for examples in figures 3A, 3B, 4B and 5A? • How to control that DRNI active GW is moved from node 2 to node 3 for examples in figures 4B and 5A? • How to control that EC SNCP endpoint in node 1 switches from W to P for example in figure 3B?
