Data Center Innovation Series: Intelligent Buffer Management

Cisco intelligent buffer management includes approximate fair dropping (AFD) with elephant trap (ETRAP), and dynamic packet prioritization (DPP) functions. It uses an algorithm-based architectural approach to address the buffer requirements in modern data centers. It offers a cost-effective and sustainable solution to support the ever-increasing network speed and data traffic load.

Tom is Senior Vice President and Chief Technology Officer for the Data Center Networking Group at Cisco Systems, and a guest lecturer at Stanford university where he earned his bachelor’s and master’s degrees in electrical engineering.
