The  Protocol Engineering Laboratory (PEL) directed by Professor Paul Amer at the University of Delaware is dedicated to the research, development, and improvement of new and existing computer network protocols. PEL researchers are investigating innovative transport protocol alternatives to TCP and UDP (such as SCTP) emphasizing these alternatives within army networks to provide efficient communications under mobile, ad-hoc network conditions.

Present/Past Sponsors
Current Research
Innovative Transport Layer Protocols
The ongoing development of alternative transport protocols (e.g., SCTP) which provide several benefits over traditional transport protocols such as TCP and UDP, especially in supporting army and/or multimedia applications.  Current focus is on transport layer multihoming and multistreaming.

Past Research
Estelle: Formal Protocol Specification and Testing
Estelle is a standard formal description technique (ISO9074) created within the International Organization for Standardization (ISO) Open Systems Interconnection (OSI) project, used for the formal specification of communications protocols. [Read More]
