te performance of 23 Mbps (40 Gbps @ 192 Bytes). The deployment of an intelligent NFV through the EPA aware delivery stacked onto underlying NFVI with correct extended information model having deterministic VNF attributes is easy to demonstrate using deployment scenario. The benefits of doing an "intelligent" NFV deployment through the EPA aware delivery stack onto underlying NFVI using the correct extended information model which contains the attributes required for deterministic VNF performance can easily be demonstrated using this deployment scenario. Brocade vRouter with the correct Downloaded: 4/15/2022 9:44:49 AM Nova Southeastern University IP Address: 137.52.76.29 Virtualizing Network Functions in Software-Defined Networks EPA parameters exposed via VNF Descriptor and en- forced by the Cyan NFVO and the VIM is deployed. The Brocade vRouter can achieve the high performance as expected by design correctly implementing the PCIe pass through, the NUMA awareness, CPU pining, and huge page requirement as required by the Brocade VNF. Non-Standardized (Non-ETSI) in Network Function Virtualization The existence of the ETSI workgroup shouldn't imply that it is the place where service virtualization is studied and standards are conducted for the production service virtualization offerings. This is far from the case, e.g. The academic community is starting to study some of the questions around NFV as part of the burgeoning SDN research they are performing. The service chaining has been targeted by many existing controller/framework vendors as one of their applications and a few startups viz. LineRate, Embrane are positioning controllers for layer 2 through layer 7 that use their own virtualized services while working. Existing vendors of highly integrated network elements are delving into intermediate or total virtualization of their platform/solutions. Though it is too early for a complete section in this revision, the IETF has already begun soliciting interest in the area of service chaining. A proposed workgroup n
