Package ClusterShell :: Module Topology

Module Topology

ClusterShell topology module

This module contains the network topology parser and its related classes. These classes are used to build a topology tree of nodegroups according to the configuration file.

This file must be written using the following syntax:

# for now only [routes] tree is taken in account: [routes] admin: first_level_gateways[0-10] first_level_gateways[0-10]: second_level_gateways[0-100] second_level_gateways[0-100]: nodes[0-2000] ...

Classes

TopologyError
topology parser error to report invalid configurations or parsing errors

TopologyNodeGroup
Base element for in-memory representation of the propagation tree.

TopologyTree
represent a simplified network topology as a tree of machines to use to connect to other ones

TopologyRoute
A single route between two nodesets

TopologyRoutingTable
This class provides a convenient way to store and manage topology routes

TopologyGraph
represent a complete network topology by storing every "can reach" relations between nodes.

TopologyParser
This class offers a way to interpret network topologies supplied under the form :
