A basic requirement for communication in a heterogeneous computing environment is a standard external data representation. Abstract Syntax Notation One (ASN.1) has been widely used in international standard specifications; its transfer-syntax, the Basic Encoding Rules (BER), is used as the external data representation. This paper presents a HER implementation called the ED library. The ED library includes a number of encoding and decoding routines that may be used as primitive functions to compose encoders and decoders for arbitrarily complicated ASN.1 data-types. Based on the ED library, an ASN.1-C compiler, called CASN1, is designed and implemented to free the protocol implementors from the arduous work of translating protocol-defined data-types and constructing their encoders and decoders. Given an ASN.1 protocol specification, CASNI automatically translates the input ASN.1 modules into C and generates the BER encoders and decoders for the protocol defined data-types. This paper discusses the CASN1 design principles, user interface, and some example applications. The performance of the ED library and generated CASN1 code is also measured and discussed.
