Abstract

The folded Petersen network is constructed by iteratively applying the cartesian product operation on the well-known Petersen graph. This topology provides regularity, node- and edge-symmetry, optimal connectivity (and therefore maximal fault-tolerance), logarithmic diameter and modularity. With the same node-degree and connectivity, the n-folded Petersen network, F P n , has smaller diameter with more nodes than the 3n-dimensional binary hypercube Q 3n , and its packing density is higher compared to several other product networks.

In this paper, we consider several fundamental communication problems on the folded Petersen network: sending a message from one node to another (or routing), permutation routing, i.e., every node is source and destination of precisely one message, broadcasting a message from a source to all other nodes (one- to- all broadcasting), sending the same message from every node to all other nodes (multinode-broadcasting or gossiping), personalized communications like scattering (sending from a single node distinct messages to each one of the other nodes) and total exchange (each node sending distinct messages to all other nodes).

All of these communication problems are studied under two assumptions, the single link availability (SLA) in which each node can send or receive messages over a single link at each time step, and the multiple link availability (MLA) in which each node can exchange messages with all of its neighbors at each time step. We derive lower bounds for these problems and design optimal algorithms in terms of both time and the number of message transmissions. The results are based on the construction of optimal height spanning trees in the folded Petersen network F P n .
