A method of request routing redirection includes: receiving, by a first content delivery network (CDN) among a plurality of CDNs connected by CDN interconnection (CDNi), a domain name system (DNS) request including a list of CDN-provider-identifications (IDs) of higher CDNs, from a client; determining whether the client's request is processable; and when the client's request is not processable, redirecting the request, while preventing a loop of the request routing on the basis of the list of the CDN-provider-IDs.

Method of request routing re-direction with loop detection and prevention

A first cloud computing data center and a second cloud computing data center are connected through a provider backbone bridge network (PBBN), and a plurality of working connection paths and protection connection paths are formed between end points between the first cloud computing data center and the second cloud computing data center and between end points within a cloud computing data center through the PBBN. When a failure occurs in the working connection path, the working connection path is switched to a corresponding protection connection path.

Method and apparatus for managing connection path failure between data centers for cloud computing

A traffic control apparatus is provided which includes an interface connector to transmit/receive an Internet Protocol (IP) packet to/from an external circuit, a frame generator to receive the IP packet through the interface connector and to generate a Media Access Control (MAC) frame, and a network processor to transmit/receive the IP packet to/from the frame generator, to execute at least one programmable application, and to identify and classify the at least one programmable application.

Apparatus and method for controlling traffic

Provided is a flow generation method for Internet traffic measurement. In the flow generation method, dependency between packet collecting time and flow generating time is removed using a virtual timer and a flow generation completion processing interval is controlled to skip by a unit time in response to a user's request. Also, a fragmented packet processing method is selectively used at need and a FIN timeout is applied selectively to a timeout mechanism used in flow generation completion. Thereby, this invention can improve accuracy and efficiency of Internet traffic measurement.
