Example 9 with NetworkResource

the class MsoNetworkAdapterImpl method updateNetwork.

/**
 * This is the "Update Network" web service implementation. It will update an existing Network of the requested type
 * in the specified cloud and tenant. The typical use will be to replace the VLANs with the supplied list (to add or
 * remove a VLAN), but other properties may be updated as well.
 *
 * There will be a pre-defined set of network types defined in the MSO Catalog. All such networks will have a
 * similar configuration, based on the allowable Openstack networking definitions. This includes basic networks,
 * provider networks (with a single VLAN), and multi-provider networks (one or more VLANs).
 *
 * Initially, all provider networks must currently be "vlan" type, and multi-provider networks must be multiple
 * VLANs on the same physical network.
 *
 * This service supports two modes of Network update: - via Heat Templates - via Neutron API The network
 * orchestration mode for each network type is declared in its catalog definition. All Heat-based templates must
 * support some subset of the same input parameters: network_name, physical_network, vlan, segments.
 *
 * The method returns a NetworkRollback object. This object can be passed as-is to the rollbackNetwork operation to
 * undo everything that was updated. This is useful if a network is successfully updated but orchestration fails on
 * a subsequent operation.
