A CDE Definition
A communications protocol designed with less complexity in order to reduce overhead. For example, it may use fixed-length headers because they are faster to parse than variable-length headers. To keep the memory requirement low, a lightweight protocol may eliminate many options that are part of the standard. See lightweight.
Compact. Software is considered lightweight if it utilizes a limited amount of RAM. For example, an operating system is considered lightweight if its kernel requires a small amount of memory (said to have a "low footprint"). See footprint and lightweight protocol.
