抽象语法描述ASN.1已经被广泛地运用于协议通信。在VOIP应用中,同样也要用到ASN.1编解码。但是由于H.323协议栈本身的asn描述文件较大,使得传统的ASN.1编解码方案在资源有限的嵌入式系统中并不适用。文章在实际开发项目的基础上,提出了一个适用于嵌入式系统的解决方案。
Abstract Syntax Description ASN.1 has been widely used in protocol communications. In VOIP applications, also need to use ASN.1 codec. However, due to the large asn description file of the H.323 protocol stack, the traditional ASN.1 codec solution is not applicable in a resource-limited embedded system. Based on the actual development project, the article presents a solution for embedded systems.
