TL;DR: In this paper, a secure federated transfer learning (FTL) method was used for traffic classification in autonomous network management, which is a way to collaboratively train learning models with privacy-preservation.

TL;DR: The proposed e-VeMAC protocol is an enhanced vehicular MAC protocol that supports more parallel transmissions than the VeMAC protocol and avoids unnecessarily releasing time slots when a node just enters the communication range of each other.

TL;DR: This paper divided an Autonomous System (AS) in several groups of routers to cache the popular contents and used Consistent Hashing to reduce overlapping contents and forward the request efficiently.

TL;DR: The proposed architecture provides an environment that enables the advent of service providers and rapidly introduces multimedia applications, considering network scalability, and adopts a new service component, which is called Omnipresent Personal Environment Manager (OpeMgr).

Abstract: Distributed Denial-of-Service attack (DDoS) is one of the most outstanding menaces on the Internet. A DDoS attack generally attempts to overwhelm the victim in order to deny their services to legitimate users. A number of approaches have been proposed for defending against DDoS attacks accurately in real time. However, existing schemes have limits in terms of detection accuracy and delay if the IDRS (Intrusion Detection and Response System) deployed only at a specific location detects and responds against attacks. As in this case, it is not able to catch the characteristic of the attack which is distributed in large-scale. Moreover, the existing detection schemes have vulnerabilities to intellectual DDoS attacks which are able to avoid its detection threshold or delay its detection time. This paper suggests the effective DDoS defense system which uses the collaborative scheme among distributed IDRSs located in the vicinity of the attack source or victim network. In proposed scheme, both victim and source-end IDRS work synergistically to identify the attack and avoid false alarm rate up to great extent. Additionally, we propose the duplicate detection window scheme to detect various attacks dynamics which increase the detection threshold gradually in early stage. The proposed scheme can effectively detect and respond against these diverse DDoS attack dynamics.
