Traffic Optimization at the Application Level Proof of concept, development and usefulness evaluation of the ALTO solution

In global networks, Border Gateway Protocol (BGP) is widely used in exchanging routing information. While the original design of BGP did not focus on security protection against deliberate or accidental errors regarding to routing disruption, one of fundamental vulnerabilities in BGP is a lack of insurance in validating authority for announcing network layer reachability. Therefore, a distributed repository system known as Resource Public Key Infrastructure (RPKI) has been utilized to mitigate this issue. However, such a validation requires further deployment steps for Autonomous System (AS), and it might cause performance and compatibility problems in legacy network infrastructure. Nevertheless, with recent advancements in network innovation, some traditional networks are planning to be restructured with Software-Defined Networking (SDN) technology for gaining more benefits. By using SDN, Internet eXchange Point (IXP) is able to enhance its capability of management by applying softwarized control methods, acting as a Software-Defined eXchange (SDX) center to handle numerous advertisement adaptively. To use the SDN method to strengthen routing security of IXP, this paper proposed an alternative SDX development, SD-BROV, an SDX-based BGP Route Origin Validation mechanism that establishes a flexible route exchange scenario with RPKI validation. The validating application built in the SDN controller is capable of investigating received routing information. It aims to support hybrid SDN environments and help non-SDN BGP neighbors to get trusted routes and drop suspicious ones in transition. To verify proposed idea with emulated environment, the proof-of-concept development is deployed on an SDN testbed running over Research and Education Networks (RENs). During BGP hijacking experiment, the results show that developed SD-BROV is able to detect and stop legitimate traffic to be redirected by attacker, making approach to secure traffic forwarding on BGP routers.

Auxiliary Input

Games are interactive applications that require input devices in order to send messages for the interaction. Normally this input devices are mouse, keyboards and joysticks. Lately, this input has been done in different ways, such as voice, touch and movement with new input devices. One type of input that has not been very explored is the use of the brain waves as a input for the game. While in past these devices where expensive, nowadays Brain Computer Interface (BCI) have become accessible, cheap and can be acquired with nonintrusive top off-the-shelf products, which can create a new paradigm of interaction for games. This work presents a novel architecture and framework that can help the development of games with both BCI and traditional interfaces. As a proof of concept, this paper shows the experience in designing and developing a game prototype using the framework and EEG brainwaves as one of the players input. The game is an action slice game, similar to Fruit Ninja, called MindNinja. This game differ form most BCI game, since it is based on an action game, using touch input where the BCI is used as an auxiliary input to change the game behavior. This game was tested and evaluated with a group of person, showing promising results in the fun level, as well as increasing the attention level of subjects.
