TECHNIQUE FOR MANAGING AN ALLOCATION OF A VLAN

摘要

Techniques for allocation of a VLAN for a deployment by at least one VM provided on a host in a network. A VLAN manager is adapted to allocate a free physical VLAN identifier to the requested virtual VLAN identifier. The VLAN manager queries a VLAN mapping table for determining a free physical VLAN identifier. In case the physical VLAN identifier for the requested virtual VLAN identifier is in use, a procedure for determining the at least one free physical VLAN is performed. The determination procedure may be based on pre-defined zoning or it may apply a retagging after a free physical VLAN identifier has been calculated, The determined physical VLAN identifier is assigned to the requested VLAN. The VLAN switch devices are instructed about the assignment between the virtual and the physical VLAN identifier in order to apply the assignment of the data packets transported over the requested VLAN.
