Abstract: A method (200) and system (100) for encapsulating multicast packets into unicast packets, the system comprises a TCP/TP communication stack having means for receiving a plurality of incoming multicast packets from an incoming wireless module (102), a first translation module (106) having means for translating the plurality of incoming multicast packets to a recognizable format for mapping, an intelligent hashing table (110) comprises means for storing a extracted subscriber IP address, a subscriber MAC address and a TTL period, a second translation module (114) comprises means for translating the unicast packets to a format recognizable for transmission, means for transmitting the unicast packets into an outgoing wireless module (116) and mapping modules comprises of a first mapping module (108) and a second mapping module (112). The mapping modules (108, 112) comprises the method of extracting the subscriber IP address, the subscriber MAC address and the TTL period from a plurality of incoming multicast packets (302), storing the subscriber IP address, the subscriber MAC address and the TTL period in an intelligent hashing table (304); encapsulating the plurality of incoming multicast packets into a plurality of unicast packets (306), forwarding the unicast packets for mapping (308) and multiplying the unicast packets in the presence of multiple subscribers (310).

Abstract translation: 一种用于将多播分组封装成单播分组的方法（200）和系统（100），所述系统包括具有用于从输入无线模块（102）接收多个输入多播分组的装置的TCP / TP通信栈，第一翻译模块 （106）具有用于将所述多个传入组播分组翻译成可识别格式以进行映射的装置，智能散列表（110）包括用于存储提取的用户IP地址，用户MAC地址和TTL时段的装置，第二转换模块 （114）包括用于将所述单播分组转换为可识别用于发送的格式的装置，用于将所述单播分组发送到输出无线模块（116）的模块，并且映射模块包括第一映射模块（108）和第二映射模块 ）。 映射模块（108,112）包括从多个输入多播分组（302）中提取用户IP地址，用户MAC地址和TTL时段的方法，存储用户IP地址，用户MAC地址和TTL 在智能散列表（304）中创建周期; 将所述多个传入多播分组封装成多个单播分组（306），在存在多个用户（310）的情况下转发所述单播分组以进行映射（308）并将所述单播分组相乘。
