示例1: networkx_to_mininet
# 需要导入模块: from mininet import topo [as 别名]
# 或者: from mininet.topo import Topo [as 别名]
def networkx_to_mininet(G, hosts, switches, mapping):
# Conversion from NetworkX topology into FNSS topology
fnss_topo = fnss.Topology(G)
# G is a NetworkX Graph() and fnss_topo is a FNSS Topology(): hosts and switches are indistinguishable.
# We exploit 'mapping' returned from parse_network_xml() for nodes role differentiation.
# We can't use fnss.adapters.to_mininet() because we need a customized nodes relabeling.
# TODO link capacities!! http://fnss.github.io/doc/core/_modules/fnss/adapters/mn.html
# Conversion from FNSS topology into Mininet topology
