Abstract :
Current file-like data exchange methods of high-liquid securities information are mainly based on some high redundancy formats such as DBF, which wastes bandwidth resource and induces high disseminating latency. Besides, the file segmentation technique these methods adopt aggravates bandwidth overhead and causes extra latency. To solve the problem, this paper presents FFTP - an Extended FAST based high-liquid securities data exchange method. FFTP promotes high-liquidity in two aspects. First, by mapping records of the file-like data to FAST messages, FFTP can significantly reduce redundancy of exchange data by leveraging high efficiency encoding of Extended FAST, and thus bandwidth overhead can be reduced. Second, since the encoding procedure is based on the granularity of a record, the receiver can instantly decode records from a file segment and no retransmission of the whole file is needed, which effectively reduce latency of records of the received segments. We implemented the Extended FAST and the FFTP prototype. The experiments demonstrate while avoiding full file retransmission, FFTP can decrease DBF´s size by over 70%, very close to some general-purpose compression methods such as bzip, gzip, rar, which verified the feasibility and effectiveness of the new method.
