利用区间管理算法实现的TCP流重组技术

Research on TCP Stream Reassembling Techniques Based on Interval Management Algorithm

流量分片重组技术作为获取网络流量的基础技术之一,在网络空间的复杂情况下,一直都有各种各样的局限性。针对大流量高并发场景的传输控制协议(Transport Control Protocol,TCP)流量重组需求,详细调研了主流的分片重组技术的优缺点,拓展了适用于数据报文的区间管理算法,对TCP流重组流程进行优化,解决了目前在大流量高并发场景下,TCP流重组效率低、重组完整度不足的问题。

Traffic fragment reassembling techniques, as one of the basic techniques for accessing network traffic, always have various limitations in the complexities of cyberspace. To address the needs of TCP(Transport Control Protocol) traffic reassembling in high traffic and high concurrency scenarios, this paper investigates in detail the advantages and disadvantages of the mainstream fragment reassembling techniques, extends the interval management algorithm applicable to data messages, and optimizes the TCP traffic reassembling process. It solves the current problems of slow TCP traffic reassembling efficiency and insufficient reassembling integrity in high traffic and high concurrency scenarios.
