Network Emulation Using GraphGen

Sometimes researchers need to emulate very large and complex topologies connecting enclaves of nodes. The core of such topology may contain hundreds of nodes and it may be impractical to emulate it using physical machines. This guide shows how to replace the core of such topology with a single Click router, which faithfully emulates bandwidth and delay on inter-router links.
