sentences:  UDP-Lite is described in RFC 3828.UDP-Lite is based on User Datagram Protocol (UDP), but unlike UDP, where either all or none of a packet is protected by a checksum, UDP-Lite allows for "partial checksums" that only covers part of a datagram (an arbitrary count of octets at the beginning of the packet), and will therefore deliver packets that have been partially corrupted.It is designed for multimedia protocols, such as Voice over IP (VoIP) or streamed video, in which receiving a packet with a damaged payload is better than receiving no packet at all.
