Since its advent in 1981, TCP has been subject to a tremendous amount of research effort and enhancements for achieving better performance over various network environments and application scenarios. Due to the transmission characteristics of optical burst switched networks, such as random burst dropping, retro-blocking (i.e., bursts proceeding or delayed from their actual reservation time slot), burstification delay, and burst signaling delay, TCP could be significantly affected if no corresponding countermeasure and enhancement are developed. In this review article we provide a comprehensive survey on reported studies for TCP enhancements over OBS networks in order to mitigate the numerous side effects due to the buffer-less characteristic of burst transmission. Furthermore, we closely analyze TCP behavior over OBS networks with various burst transmission characteristics while highlighting the open challenges that have not yet been extensively tackled or solved.
