Gutman argues convincingly that the stability of the black family encouraged the tra mi ion of - and so was crucial in sustaining - the black heritage of folklore ， music ， and religious expre ion from one generation to another ， a heritage that slaves were continually fashioning out of their african and american experiences 古特曼人令人信服地论辨道，黑人家庭的稳定有助于包括民间传说、音乐、及宗教表达在内的黑人文化遗产一代一代传递下去，因而在维持文化遗产方面也起着至关重要的作用，而对于这种文化遗产，黑奴们不断地从其非洲和美洲的经历中予以丰富发展。
It reframes the traceback problem as a polynomial reconstruction problem , and uses techniques from algebraic coding theory to provide robust methods of transmission and restriction . the scheme is a new solution to the traceback problem during a dos attack ; the honeypot for ddos , which is a tool of traceback , lures the attacker to believe that he successfully compromised a slave for his needs , convincingly simulating the architecture of a potential ddos attack ; the source - based approach to ddos defense , which is a useful adjunt to traceback systems , deploys a ddos defense system at source - end networks . attacks are detected by monitoring two - way traffic flows , and the attacks originating from source networks are stopped by rate - limiting ; the routing mechanism based on pushback treats ddos attacks as a congestion - control problem 最后，就有关ddos攻击反向追踪问题，从四个方面对其解决方案进行了研究：在分析比较几种反向追踪算法的基础上，着重研究了代数方法编码反向追踪信息的方案，该方案把追踪重构问题当作多项式重构问题，使用代数编码理论技术提供鲁棒的传送和重构方法，是dos攻击过程中的反向追踪问题的一种新的解决方法； ddos陷阱作为反向追踪的工具，引诱攻击者相信自己成功与所需的傀儡主机通话，令人信服地模拟出潜在ddos攻击体系结构；基于源的ddos防御方法作为反向追踪有用的补充，将防御系统部署在源网络，通过监控双向流量检测攻击和限制速率终止来自源的攻击；基于向后倒推的防御ddos的路由机制把ddos攻击看作拥塞控制问题，添加功能到每个路由器来检测并优先丢弃可能属于攻击的包，通过向后倒推上级路由器也得到通知而把这样的包丢弃。
Gutman argues convincingly that the stability of the black family encouraged the transmission of - and so was crucial in sustaining - the black heritage of folklore ， music ， and religious expression from one generation to another ， a heritage that slaves were continually fashioning out of their african and american experiences 古特曼令人信服地说明，稳定的黑人家庭激励了传统的黑人民间传说、音乐及宗教一代一代人的传递（对于继续保持这些传统也是重要的） ，在传递过程中，奴隶将他们在非洲和美国的经历加入进去，使这些传统更加符合时代潮流。
