Abstract: Disclosed are a logical network separation method and apparatus. The logical network separation method includes generating a first hash key on the basis of address information included in a service request packet, generating hash information on the basis of a transmission property of the service request packet corresponding to the first hash key when the same hash key as the first hash key is not in the hash table, and generating the policy about the reception of the service response packet corresponding to the service request packet on the basis of a destination of the service request packet. Accordingly, it is possible to block a cyber attack such as hacking, a malicious program, etc.
Abstract translation: 公开了一种逻辑网络分离方法和装置。 逻辑网络分离方法包括：基于包括在服务请求分组中的地址信息生成第一散列密钥，当相同的散列密钥时，基于与第一哈希密钥对应的服务请求分组的传输属性生成哈希信息 因为第一哈希密钥不在哈希表中，并且基于服务请求分组的目的地生成关于与服务请求分组相对应的服务响应分组的接收的策略。 因此，可以阻止诸如黑客，恶意程序等网络攻击。

Abstract: Disclosed are a network apparatus and an operating method thereof. The network apparatus includes: a security authentication module that executes security authentication of a distributed denial of service (DDoS) attack when a predetermined packet requests access to a particular service server to which the security authentication is applied, at the time of inputting the predetermined packet; and a communication module that transmits the predetermined packet security-authenticated by the security authentication module through a transmission route of the particular service server, so as to easily defend the DDoS attack by using a pseudo state of a service procedure.

Abstract: Disclosed are a method and apparatus for modeling a network configuration protocol (NETCONF)-based network device instruction with a yet another next generation (YANG) language. The method of modeling the NETCONF)-based network device instruction with the YANG language includes: searching for at least one instruction from a source file for controlling a NETCONF-based network device; parsing the retrieved instruction into a plurality of tokens; mapping each parsed token with a data type of the YANG language according to a previously defined mapping rule; and generating a YANG model corresponding to the at least one instruction according to mapping results. Accordingly, the YANG model is immediately generated reflecting changes in an instruction of a network system.
