APPARATUS AND METHOD FOR SEGREGATING TENANT SPECIFIC DATA WHEN USING MPLS IN OPENFLOW-ENABLED CLOUD COMPUTING

摘要

A tenant database is used to add tenant ID information to the cloud network manager (CNM) address mapping table to isolate tenant specific data to a tenant ID to the CNM. The CNM maintains a mapping among a plurality of items in a plurality of databases or tables. The plurality of databases or tables include a tenant database (DB), a tenant identifier to tenant label (TITL) table, a top of rack server label to virtual switch link label (TLVLL) table, a label mapping table (SMVL), and a CNM address mapping table. The CNM uses the plurality of databases to generate tenant specific labels that are added to packets sent between tenant virtual machines (VMs).
