1 Implementation and Testing of Soft Patch Panel Yasfmi Ogawa (NTT) Tetsro Nakamra (NTT) DPDK Smmit - San Jose 2017

2 Agenda Motivation SPP (Soft Patch Panel) Design and Network Configration Implementation Performance Test Use-case PoC Implementation Performance Test Smmary 2

3 Motivation Large-scale clod for telecom services Service Fnction Chaining for virtal network appliances Flexibility, Maintainability and High-Performance Load Balancer L2 Switch Monitoring Secrity Web Service Variety kinds of service apps on s L3 Roter MPLS Firewall DPI Adio Video 3

4 Soft Patch Panel Change network path with patch panel like simple interface High-speed packet processing with DPDK Update network configration dynamically withot terminating services Virtal Ports Physical Ports 4

6 Network Configration SPP Controller manages connection between secondary processes Each of secondary has its connection as patch information Patch can be pdated dynamically while rnning NFV applications Gest SPP Controller Terminal spp> sec 1; patch 0 1 spp> sec 1; patch 1 2 spp> sec 1;forward Gest NFV App NFV App vhost port#1 vhost Host SPP Controller sec#2 sec#1 port#0 sec#3 port#2 6

7 Patch Management Each of secondary has patch information and port attribtes Patch information is managed as an array of port strct, "ports_fwd_array" Port ID and type is defined as an array of port_map strct, "port_map" strct port { int in_port_id; int ot_port_id; int16_t (*rx_fnc)(int8_t,int16_t,strct rte_mbf **,int16_t); int16_t (*tx_fnc)(int8_t,int16_t,strct rte_mbf **,int16_t); }; strct port_map { int id; enm port_type port_type; strct stats *stats; strct stats defalt_stats; }; Host port#2 (ring) port#0 (phy) port#1 (phy) ports_fwd_array[0].in_port = -1 ports_fwd_array[0].ot_port=2 ports_fwd_array[0].rx_fnc=rx_brst() ports_fwd_array[0].tx_fnc=tx_brst() ports_fwd_array[2].in_port = 2 ports_fwd_array[2].ot_port=1 ports_fwd_array[2].rx_fnc=rx_brst() ports_fwd_array[2].tx_fnc=tx_brst() port_map[0].id = 0 port_map[0].port_type = PHY... port_map[0].id = 2 port_map[0].type = RING... 7
