“…However, the cPCN signaling architecture fits very well to the centralized nature of the control architecture of emerging Software Defined Networks (SDN, see e.g. [7][8][9] ) that (amongst others) takes care of flow routing in the data plane. Therefore, the outcome of our study also shows potential for enriching SDN with flow admission control and flow termination functionalities according to the cPCN approach.…”

Flow termination signaling in the centralized pre-congestion notification architecture

a b s t r a c tPre-congestion notification (PCN) protects inelastic traffic by using feedback on network link loads on and acting upon this accordingly. These actions comprise to admission control and termination of flows. Two PCN architectures have been defined by IETF: the centralized and decentralized PCN architecture. The decentralized PCN architecture has received much attention in the literature whereas the centralized PCN architecture has not. In the decentralized architecture, feedback is sent from the egress nodes to ingress nodes, which then take and apply decisions regarding admission of new flows and/or termination of ongoing flows. Signaling occurs only between ingress and egress nodes.In the centralized architecture these decisions are made at a central node, which requires proper signaling for action and information exchange between the central node and the egress and ingress nodes. This signaling has been suggested by other authors, but is not fully defined yet. Our contribution is twofold. We define signaling in the centralized PCN architecture focussing on flow termination, which completes the definition of the signaling in the centralized PCN architecture. Secondly, we run extensive simulations showing that the proposed signaling works well and that the performances of the centralized PCN and the decentralized PCN architectures are similar. Hence, it is expected that results from existing research on the effectiveness of decentralized PCN are also valid when the centralized PCN architecture is used.

Abstract:One of the main design aspects of the Tactile Internet system is the 1 ms end-to-end latency, which is considered as being the main challenge with the system realization. Forced by recent development and capabilities of the fifth generation (5G) cellular system, the Tactile Internet will become a real. One way to overcome the 1 ms latency is to employ a centralized controller in the core of the network with a global knowledge of the system, together with the concept of network function virtualization (NFV). This is the idea behind the software defined networking (SDN). This paper introduces a Tactile Internet system structure, which employs SDN in the core of the cellular network and mobile edge computing (MEC) in multi-levels. The work is mainly concerned with the structure of the core network. The system is simulated over a reliable environment and introduces a round trip latency of orders of 1 ms. This can be interpreted by the reduction of intermediate nodes that are involved in the communication process.

Nowadays operators are forced to struggle with low level configurations and exclusives of network devices vendors to establish and maintain a secure connection and implement complex management policies on these devices. Software Defined Networks (SDN) are a new style of computer networks which provides new facilities and methods for network management and configuration by separating control level and data level. In order to improve the video Quality of Service (QoS) and increase the efficiency of the end-to-end performance, it is necessary to select the best route and implement QoS for videos, whilst there may be different routes between the transmitter and the receiver and due to network's complexity, discover the optimal route would be impossible. Hence the existing solution is a SDN with an overall view. In this paper, At First, QoS definitions are expressed. Second, traffic engineering methods in current networks is discussed. Finally, a new technique to improve QoS over SDN is proposed. Results of performance evaluation showed that the proposed method is better than existing methods.
