The SDN controllers maintain the flow tables to manage all the data flows passing through the SDN switches. In some cases, monitoring activities are required for the specific flows to detect the special events. Current de facto standard of SDN architecture enforces SDN switch to stay awake all the time from the time it receives the event monitoring request from SDN controller to catch the target event...
Recently there have been a lot of discussions about the benefits and usages of SDN technologies, but not many practical proposals for how to interconnect the various heterogeneous and disparate networks maintained by the telecommunication companies. Current level of SDN technologies does not show any sign of transforming the whole legacy network into the SDN oriented one all at once, but instead,...
With the emergence of significant amounts of mobile and cloud services, the scale of Data Center Networks (DCNs) has been growing rapidly. A DCN has different network requirements compared to a traditional Internet Protocol (IP) network, and the existing Ethernet/IP style protocols constrain the DCNs scalability and its manageability. In this paper, we present a scalable failover method for large...
Recently, the walls of wired and wireless networks are breaking down to bring the cluster environment of networks to a chaos, mainly due to the exponential gross of the wireless devices.
This Nowadays, along with popularity of application and use of network technologies, the structure of network is being complex and enormous to support emerging applications. A NMS (Network Management System) is required to support emerging services through the complex network structure. In this paper, we present an on-going work called SOLA (Smart One-view Look and Analysis) to integrate the existing...
In this paper, we are introducing a new view for the applications and the activities using QR codes to access the information for the objects existing in everyday human environment. This view emphasizes the possibility of the QR codes as an Analog Portal—an ambient media gate to the Digital World, because it shows the new way of access to the Internet and may be able to change the culture of retrieving...
