4 Network Slicing One of the multiple benefits that NFV brings into the table is enabling Network Slicing by allowing a physical infrastructure to be separated into multiple virtual networks that can support multiple services Source: Ericsson

6 System Overview enb NSSF EPC XOS OpenStack ONOS CORD Platform (M-CORD) UE UE OAI-SIM enodeb NSSF s1-net slice-net s6-net vmme OAI-EPC vhss s11-net vspgwc vspgwc vspgwc spgw-net Set of opensource VNF UE Synchronizer GTP-TUN vspgwc vspgwc vspgwu

7 Components Description EPC and enodeb VNF are Open-Air Interface projects. Developed by Eurecom. Open Air Interface enodeb vhss Open Air Interface Core Network OAISIM UE - enb vbbu S1 S6 vmme S11 vspgwc S5 Data Plane vspwgu INTERNET S1-U

9 Scenario Description NSSF INSTANCE MME Slice Request Message Slice Request Message is a RPC that includes the UE IMSI And returns an SPGW-ID as a String NSSF Slice Table Slice Selection SPGW Table Slice DB ID SPGW id UE SL- DIFF SERVICE S Table ServiceId Services

11 Test and Results XOS view of Services OAISM: Represents the enodeb/ue NSSF: Represents the Network Slice Selection Function VMME, VHSS, VSPGWC and VSPGWU are also represented by their own services The services that are not connected are part of MCORD deployment

12 Test and Results VNF Instances in Open Stack

13 Tests and Results The NSSF VNF is always listening to vmme requests and provides some information about the current slices every time a connection is established. When a UE connects each of their IMSI is stored along with the slice that is serving. Service differentiation is done by taking the last digit of the IMSI

14 Iperf Tests The emulated enodeb is causing a bottleneck for the E2E connection Running directly from the EPC

15 Test and Results Youtube video of the whole scenario:
