WebNext, we define a code-constrained capacity region that restricts attention to any pre-specified set of coding actions. A dynamic max-weight algorithm that acts over variable length frames is developed. The algorithm allows for random packet arrivals and supports any traffic inside the code-constrained capacity region. Webinformation graph can affect the capacity region. Their question is captured formally by the notion of criticality of an edge. Definition 1. Given an index coding problem G = (V,E), an edge e∈Eis said to be critical if the removal of efrom Gstrictly reduces the capacity region. Definition 2. The index coding problem G=(V,E)is
