    Abstract: The present invention relates to a network structure for effectively applying a software-defined networking (SDN) technology to an LTE network and an operation of a system on the basis of the same. The present invention therefore provides a method for controlling communication by an SDN controller in an SDN-based wireless communication network, the method comprising the steps of: receiving information on a UE from a gateway controller as the UE initially accesses an eNB; selecting at least one Openflow switch (OFS) for processing traffic of the UE on the basis of the information; and transmitting a request for setting a packet forwarding rule for processing the traffic of the UE to the at least one OFS.

    Abstract translation: 本发明涉及一种用于有效地将软件定义网络（SDN）技术应用于LTE网络和基于该网络的系统的操作的网络结构。 因此，本发明提供了一种用于在基于SDN的无线通信网络中通过SDN控制器进行通信控制的方法，所述方法包括以下步骤：当UE最初访问eNB时，从网关控制器接收关于UE的信息; 根据该信息，选择至少一个Openflow交换机（OFS）来处理UE的业务; 以及发送用于设置用于将所述UE的业务处理到所述至少一个OFS的分组转发规则的请求。

    Abstract: The present invention relates to a method and an apparatus for transmitting and receiving information between servers in a contents transmission network system and, more particularly, to a method and an apparatus for transmitting and receiving information between a core node and an edge node belonging to a contents transmission network. To accomplish the objective mentioned above, a method for receiving, by a receiving server, information in a contents transmission network according to one embodiment of the present invention comprises the steps of: receiving first information from a transmission server; determining a transmission unit of the first information on the basis of the received first information; transmitting, to the transmission server, a second information transmission request including information on the determined transmission unit; and receiving, from the transmission server, second information generated on the basis of the information on the transmission unit. According to an embodiment of the present invention, the method and the apparatus for transmitting and receiving information between servers in a contents transmission network system can generate compressed information on the basis of original information sought to be transmitted between servers, whereby it is possible to obtain an effect of improving optimal compression efficiency, transmission efficiency between servers, and performance regarding the delay time between both communication ends.
