• In the Scenario below, User A in Federation A wishes to create a connection with User C in Federation C
• LPO1 (A-B) and LPO2 (B-C) will be concatenated together to form LPO3 (A-C)• Only the services that will be used by Federation A to setup the lightpath are shown
– The sequence to form the E2E connection is shown on the next slide– Note the sequence is color coded to reflect the services in each domain
• Federation A = Blue, Federation B = Orange, Federation C = Green
