5 NSH-Based SFC Vertical Solution with Acceleration SFC Orchestrator + VNF Manager (Tacker) + VIM (Openstack) Orchestration Layer Opendaylight NB APIs (REST) Installation by Fuel with relevant plugins Opendaylight SB Interfaces & Protocol Plugins Openflow Plugin (NSP/NSI as match/action fields) Service Function Chaining Service Graph Netconf Datastore OVSDB Plugin Controller Layer Legacy VNFs NSH Proxy vswitchd (NXM for NSH fields) fwdtable PMD NSH-aware OpenvSwitch (act as classifier and SFF) VxLAN-GPE-NSH VTEP NSH-aware Forwarding Plane OVSDB-server PMD NSH-aware VNF VNF NSH-aware VNFs 5 Node Layer

6 OVS Based Classifier Performance Improvement encap port0 OpenvSwitch on Host1 VxLAN-GPE-NSH vport 2 decap OpenvSwitch on Host2 decap VxLAN-GPE-NSH vport port1 Tunnel port0 port1 1 3 PacketGen (generates thousands of regular flows)

7 OVS Based SFF Performance With DUT NSH-aware L2Fwd running in a VM as simple VNF VNF OpenvSwitch Measure Phy-VM-Phy performance of NSH-aware OVS with port0 PMD port1 Preliminary data shows roughly 70% line rate of 40G traffics for big packet (>1K packet size), with 5 IvyBridge cores PacketGen (generates thousands of VxLAN-GPE-NSH flows) Optimization ongoing, target 40Gb line rate for 256B packets with 2 Haswell cores

8 Performance of Accelerated NSH-aware Sample VNFs Ingress NSH encap Static NAT (inner L3 hdr only) NSH encap Egress DUT NSH-aware NAT DPPD (Data Plane Performance Demonstrator) are user space applications based on Includes a NSH decap/encap layer supporting VxLAN-GPE and Ethernet transports port0 PMD port1 Sample NSH-aware VNFs FW and NAT build on top of easy-to-use DPPD packet processing framework 10G line rate with single core, despite of packet size PacketGen (generates thousands of VxLAN-GPE-NSH flows)

9 Performance of Based NSH Proxy NSH Proxy Strip VxLAN- GPE-NSH header Add previously stripped VxLAN- GPE-NSH header Tag original frame with VxLAN header Remove original frame decap Legacy VNF 10G line rate Process packet 1 PacketGen (generates thousands of VxLAN-GPE-NSH flows) Tx Rx NSH Proxy Performance Loopback VxLAN-GPE-NSH traffics to measured performance of NSH Proxy Performs two encapsulation and two decapsulation operations. Tx: 10G line rate VxLAN-GPE-NSH traffics with 142B packet Rx: 58% line rate for single core 10G line rate can be achieves within 2 cores

10 Future Plan SFC vertical solution for OPNFV B release Fuel based installer: Tacker & Openstack, ODL, NSH-aware OVS, qemu, DPPK and NSH-aware VNFs Continues performance optimization in OVS NSH MD Type 2 and OAM (e.g. Traceroute, timestamping) support Tunneling transport encap/decap performance optimization on new Intel processors NSH acceleration with smart NICs SFC new features Direct SFC classifier control IP-Less VNFs Flow programmer for resolving multi-writer issue Symmetry flow support with TCP proxy All-in-one SFC environment Network-aware network placement algorithms and scheduler Advanced service function and service path selection algorithms NSH Proxy support 10/30/2015 Footer Lorem Ipsum Dolor Sit 10
