This invention relates to a structuring method for a multi-allotter front end system of a cluster server characterizing in including the following steps: setting up more than two front end allotters matched with two net cards, a cluster server front end system of a collecting tray, the data input end net cards of the front allotter are cascade via the collecting tray, the data output end net cards of all front allotters are connected with the switching device of the cluster server back end system, the data input end net cards are matched with a same virtual IP, all input data packets are transmitted to all front end distributes in broadcast way, every front server computes, the input data packet IP addresses or TCP port number in hash to decide if said data packet is processed.

本发明涉及网络服务器技术领域，尤其是一种集群服务器的多分配器前端系统构成方法，其特征在于：包括以下步骤，建立包括两台及以上的配置了两块网卡的前端分配器、一台集线器的集群服务器前端系统，所有前端分配器的数据输入端网卡通过集线器并行集联，所有前端分配器的数据输出端网卡与集群服务器后端系统的交换机相连；所有前端分配器的数据输入端网卡配置一个相同的虚拟IP；通过集线器将输入数据包以广播方式传输到所有前端分配器；各前端分配器对输入数据包IP地址或TCP端口号进行散列计算，决定是否处理该数据包。

In particular, when thereis an alternating group A_5 action on a Spin 4-manifold X, we obtain: If X is smooth Spin4-manifold with non-positive signature and b_1=0, denote k=-σ/16 and m=b_2~+,then 2k+3≤m if b_2~++b_2~+≠2b_2~+(Z/A_5) and b_2~+≠0,where and are subgroups of A_5 generated by the elements s=∈A_5and t=∈A_5 respectively.

特别地，在Spin 4-流形具有非交换群A_5作用时，我们得到了：若X为光滑的具有非正符号差的Spin 4-流形，b_1=0，令k=-σ／16，m=b_2~+，如果X上具有Spin交错群A_5作用，且满足b_2~++b_2~+≠2b_2~+(X／A_5)，b_2~+≠0，则2k+3≤m，其中和分别为s=∈A_5和t=∈A_5生成的A_5的子群。
