In the metropolitan area, traditional SONET/SDH circuit switched rings are likely to be replaced with optical packet/burst switching technologies. In this paper we consider a slotted WDM optical packet ring operating without resource reservation mechanisms. In such rings, optical packets in transit have priority over traffic to be inserted by the node. Packets to be inserted are thus queued acc...

The scheduling decisions made by the scheduler in a packet-oriented network have a significant impact on the network performance. By the use of cross-layer optimization techniques, the packet scheduling process can be supported, such that system resources are allocated with respect to the user’s current channel state and data requirements. In this paper, we present means to obtain optimal sched...

-Recently, there has been a significant increase in the amount of packet data services, such as web browsing, being offered over mobile phones. Data services are expected to account for the highest volume of traffic soon. However, current downlink scheduling algorithms for packet data services cannot achieve fairness and power efficiency at the same time. In this paper, we propose a novel sched...

In heterogeneous wireless network environment (HWNE), multi-mode terminals through access control and handoff technology, are always in the optimal network. However, when the users set, while a competition optimal network bandwidth limited, easily lead to network congestion and quality of service (QoS) decrease. To solve this problem, this paper configures QoS policies for heterogeneous network...

Third generation (3G) of wireless communication networks aim to provide quality-of-service (QoS) sensitive services to downlink users. Amongst these are real-time multimedia services like videoconferencing and live media streaming, where the packets to be delivered to the user have deadlines associated with them. Downlink packet scheduling plays a key role in efficiently allocating base station...

In this paper, we consider a beyond-5G scenario, where two types of users, denoted as scheduled and uncoordinated nodes, coexist on the same set of radio resources for sending data to a base station. Scheduled nodes rely solely on a centralized scheduler within the base station for the assignment of resources, while uncoordinated nodes use an unslotted Carrier Sense Multiple Access (CSMA) proto...

Load scheduling is critical to the performance of parallel processing network devices. With the rapid development of multi-core technology, efficient load scheduling scheme optimized for multi-core network processors becomes increasingly important and motivates intensive research today. In this paper, we study the relationship between two canonical scheduling schemes, packet-level scheduler and...

The impact of different message scheduling strategies on the per$ormance of a packet-switched network is explored. We present a new scheduling technique, calledAlpha scheduling, that can combine the bandwidth-fairness of round robin scheduling with nearly the optimal performance of shortestfirst scheduling. We investigate the trade-offs involved in using dtzerent routing strategies while intell...

The degree of multiplexing in datacenters necessitates careful resource scheduling, and network bandwidth is no exception. Unfortunately, today we are left with little control to accurately schedule network traffic with low overhead on end-hosts. This paper presents NicPic, a system which enables accurate network traffic scheduling in a scalable fashion. The key insight in NicPic is to decouple...
