The Medium Access Control (MAC) protocol is used to provide the data link layer of the Ethernet LAN system. The MAC protocol encapsulates a SDU (payload data) by adding a 14 byte header (Protocol Control Information (PCI)) before the data and appending an integrity checksum, The checksum is a 4-byte (32-bit) Cyclic Redundancy Check (CRC) after the data. The entire frame is preceded by a small idle period (the minimum inter-frame gap, 9.6 microsecond (µS)) and a 8 byte preamble (including the start of frame delimiter).
Hari Balakrishnan is a Professor of Computer Science at MIT.
His research is in networked computer systems, with current interests in networking, data management,
and sensing for a world of "truly mobile" devices connected to cloud services running in large datacenters.
He is an ACM Fellow (2008), a Sloan Fellow (2002), an ACM dissertation award winner (1998), and
has received several best-paper awards including the IEEE Bennett prize (2004) and the ACM SIGCOMM "test of time" award (2011).
He has also received a few awards for excellence in teaching and research at MIT
the Harold Edgerton faculty achievement award (2003), and the Jamieson (2012), Junior Bose (2002), and Spira (2001) teaching awards.
He was elected to the National Academy of Engineering in 2015.
