TTP Enables SDN

Current Implementations

• Underutilization of ASIC capabilities • OVS programs the TCAM tables

• Underuse of Openflow capabilities • Exposing the MAC/IP tables assuming

a fixed pipeline

• Only priority based lookups • Features such as group-tables

implemented in TCAM

• Results in an expensive solution • Scale restricted to TCAM size

TTP: Unicast Routing Pipeline

• Utilize all ASIC tables (VLAN+MAC+IP+TCAM) via Openflow

• Enables flexible pipelines • Choose between priority or LPM

algorithms for lookups

• Scale comparable to incumbent routers/switches
