Device Performance Analysis of Cloud Computing Data Center Two-Layer Interconnection Model Based on MPLS/IP Core Backbone Network

By analyzing the difference of protocol construction angle and equipment processing angle between VPLS whose core is MPLS and VPLS two-layer networking model whose core network in IP network, this paper has proposed that PE equipment performance is easy to overload because VPLS two-layer networking model based on IP costs a large number of resource when constructing GRE or GREoIP sec. It has gathered and analyzed the core equipment performance under different architectures in GNS3 simulation environment. Comparing with the consumption situation of the present popular core equipment performance under different architectures, this paper has proposed the present optimal two-layer interconnection model which has combined VPLS, network virtualization technology and link aggregation technology.
