1. Management and Design : Drag and Drop Network Design 2. Security : Network isolation and access control (ACL) 3. Automation: VM Mobility and Traffic Steering Mobility support of physical hosts and VMs Routing / Path management Layer 2 multipath routing (N=8 ) Operational Rerouting of flows (without any packet loss) Automatic detour of all flows through nodes Redirection Redirect matched flows with specified 12 tuple flow entries (exact match, wild card match, and its any mix) 4. Reliability Controller: Active-Standby Redundancy Switches: N Active Redundancy Links : Link Aggregation, Multi-Chassis LAG (N Active) Automatic network failure recovery (for all failure modes) 5. Openness Services independent from hardware 8 NEC SDN Unique Features Awards
Q1. Numbers of flow in switch? OpenFlow is based on flow switching architecture and requires a lot of flow entry in switches Answer From NEC: NECs switch has extra TCAM to accommodate up to 160K flow entry (commercial chip has only 2K to 4K flow entry) Q2. Multi-layer forwarding? OpenFlow 1.0 specifies 12 tuple (L1/L2/L3/L4) based matching condition and header rewriting Answer From NEC: NEC PFS provide hardware based (not software!) 12 tuple matching condition and rewriting (mac rewriting, strip VLAN, IP header and etc.) SDN Answer From NEC
SDN Answer From NEC Q3. Network virtualization OpenFlow is just a protocol and doesnt provide network virtualization. Answer From NEC: NEC provide VTN (Virtual Tenant Network) which completely separate physical and logical network resource. User can fully design and configure network only logical views Q4. Broadcast OpenFlow is controller based architecture. Controller need to manage all broadcast traffic as single point. Answer From NEC: NEC has wire rate broadcast/multicast solution, In-band BC/MC as vender extension.
