CONGA• It is a Global Collision Awareness Load Balancing technique

• Its purpose is the minimize delays on the network due to link failure

• It is implemented in the ACI of Data Center fabrics

• Uses:

• Overlay Header Encapsulation

• @Link Path to Destination Table

• 3-Bits metric system

CONGA DESIGN-1

• endpoint (server or VM) sends a packet to the fabric

• encapsulates the packet

• The spine switches forward the packet to its destination leaf based entirely on the outer header

CONGADESIGN-2

• Congestion metric in the overlay header

• The metric is updated hop-by-hop

• This information is stored at the destination leaf on a per source leaf, per path basis
