Process used to interleave the pieces of separate conversations together on the network.

Division of the data stream into smaller pieces.

tracks delay between end devices

enables consistent network paths for communication

allows modification of the original data before transmission

identifies pieces of data as part of the same communication

ensures that data pieces can be directed to the correct receiving end device
