A Study on Inter-VM Communication for NFV: Development and Evaluation for Single-Root I/O System using Soft Patch Panel

摘要

To avoid performance degradation with virtualization,we propose Soft Patch Panel (SPP). To get additionalfunctions for SPP, we developed a module to connectBerkeley Extensible Software Switch (BESS) to SPP.Measured system performance was 91%-99% of 14.88Mpps, the full maximum for 10 Gbps port. For furtherstudy, additional functions should be realized not in BESS,but in SPP to reduce CPU core expenses.
