The Protection Routing Algorithm (from [42])

Input: CIST_1, CIST_2 and destination node d
Output: The protection routing Rd
Step 1. Let T_i' be the skeleton(remove leaf edges) of CIST_i while i in {1,2}.
Step 2. By symmetry, node d is belong to T1'.
Step 3. Let edge e be the leaf edge of CIST_2 adjacent to node d.
Step 4. The protection routing Rd contains the edges of T1' and T2' and edge e, and all the links are directed to node d.
Step 5. Output Rd.
