Abstract--Link failures in wide area networks are common and
cause significant data losses. Mesh-based protection schemes offer
high capacity efficiency but they are slow and require complex
signaling. Additionally, real-time reconfiguration of a cross-
connect threatens their transmission integrity. On the other hand,
coding-based protection schemes are proactive. Therefore, they
have higher restoration speed, lower signaling complexity, and
higher transmission integrity. This paper introduces a coding-
based protection scheme, named Coded Path Protection (CPP).
In CPP, a backup copy of the primary data is encoded with
other data streams, resulting in capacity savings. This paper
presents an optimal and simple capacity placement and coding
group formation algorithm. The algorithm converts the sharing
structure of any solution of a Shared Path Protection (SPP)
