摘要:
There are provided an apparatus and method for security and network management based on flows. The flow-based security and network management apparatus generates data flows from network packets, and performs network management in connection with security management based on the generated data flows. Accordingly, it is possible to maximally guarantee traffic fairness between users against attack or intrusion traffic.
摘要:
A multi-layer data processing apparatus and method are provided. The multi-layer data processing apparatus includes a lower hierarchy processing unit configured to generate at least one lower hierarchy flow from input data using lower hierarchy information, and to allocate the generated lower hierarchy flows to a plurality of lower hierarchy processors to perform lower hierarchy processing in respect of the lower hierarchy flows in parallel; and a higher hierarchy processing unit configured to generate at least one higher hierarchy flow from data transmitted from the lower hierarchy processing unit using higher hierarchy information, and to allocate the generated higher hierarchy flows to a plurality of higher hierarchy processors to perform higher hierarchy processing in parallel in respect of the higher hierarchy flows.
摘要:
A multilayer parallel processing apparatus. The multilayer parallel processing apparatus includes two or more hierarchical parallel processing units, each configured to process flow data corresponding to a hierarchy that is allocated thereto in response to inputting pieces of flow data configured with two or more hierarchies, and a common database configured to be accessed by the two or more hierarchical parallel processing units and store processing results of each of the hierarchical parallel processing units.
摘要:
A flow transfer apparatus and method, which can make efficient use of limited resources in a wireless environment by dynamically mapping data flows to different transmission methods according to the characteristics of the flows, are provided. The flow transfer method includes analyzing an input packet stream to classify the input packet stream into a plurality of flows; dynamically determining a transmission method for each of the flows based on the characteristics of each of the flows; and transmitting the flows in parallel using their respective determined transmission methods.

A time stamping apparatus and method for network timing synchronization are provided. A receiving apparatus receives data from a transmitting apparatus, generates a synchronization pulse signal synchronized with a local clock of the transmitting apparatus based on the received data, wherein the received data include information regarding the transmission time of the data, measured using the local clock of the transmitting apparatus, and the receiving apparatus measures the reception time of the data using the synchronization pulse signal. Therefore, accurate network timing synchronization may be achieved.

Provided is a network flow-based scalable video coding (SVC) adaptation device. Without permitting a network transmitting end to divide image data into image data having various levels of quality and send the image data having the various levels of quality to all networks, since an adaptation device is installed in a network device of an ingress of a lower network of a subscriber and the adaptation device and the network transmitting end share network information about attributes of a terminal and the lower network of the subscriber so as to provide an image service having image quality corresponding to the terminal to the terminal, network efficiency can be maximized.

A method and apparatus for protection switching in a ring network are provided. A method for protection switching in a ring network, which includes a first ring network having first and second connection nodes and a second ring network connected with the first ring network through the first and second connection nodes, includes: receiving, by the first connection node, first and second R-APS messages transmitted from nodes belonging to the first ring network; determining, by the first connection node, the position of closure in the first ring network by using the first and second R-APS messages and topology information; receiving, by the first connection node, a topology change signal transmitted from the second ring network; and transmitting, by the first connection node, an FDB flush message with reference to the position of closure.
