METHOD, APPARATUS AND SYSTEM FOR RESOLVING DOMAIN NAMES IN NETWORK |
| 摘要 |
Method, apparatus and system for resolving domain names in network. One embodiment provides a method for resolving a domain name in a network, including: receiving, at a controller associated with a switch in the network, a domain name system (DNS) request for the domain name from the switch, the DNS request initiated by a client, the controller controlling operations of the switch in the network; and controlling processing of the DNS request based on a predefined security constraint at the controller to obtain a network address corresponding to the domain name, wherein the DNS request is forwarded by the switch to the controller in response to a DNS record related to the domain name being missed in first storage at the switch. Other embodiments of the present invention provide a corresponding apparatus and system. |
