It appeared to be a seven-year-old answer about a Floyd-Warshall algorithm. A power state for routers is introduced in [96], while the new stand-by states are applied to line-cards in [95]. b) tij(k) = tij(k-1) OR (tik(k-1) AND tkj(k-1)) In x3 the results and discussions are presented. It outperforms the base Floyd-Warshall algorithm when the graph matrix exceeds the GPU memory. a) All pair shortest path problems In Prasad and Lobiyal (2013), an ant colony optimization approach is proposed to tackle the minimum cost multicast tree with delay and bandwidth constraints problem. a) Single source shortest path Fig. Floyd Warshall Algorithm is an example of dynamic programming approach. 2. It is also known as all pair shortest path problem. The benefits are that the algorithm does not require unnecessary steps and processes, is easy to be executed and has the minimum time complexity in the worst case. 8. A graph representing a metro network. This was shown in the context of single-radio single-channel multi-hop wireless network in Wan (2009) where it was shown that the ‘maximum multiflow’ and the ‘maximum concurrent multiflow’ problems subject to bandwidth and interference constraints are NP-hard.

In [69,111] and [112], the authors address a very particular IP-BEANM problem to model the redundancy elimination mechanism, according to which, a subset of routers equipped with enhanced and power hungry capabilities can store the content of the transmitted packets: every time the same content has to be retransmitted to another ”capable” router, the routers do not send a full packet, but a simple hash that allows the receiver router to identify the content in its memory.
