This paper assumes each user has more than one queue, derives a new packet-dependant proportional fairness power allocation pattern based on the sum of weight capacity and the packet’s priority in users’ queues, and proposes 4 new cross-layer packet-dependant OFDM scheduling schemes based on proportional fairness for heterogeneous classes of traffic. Scenario 1, scenario 2 and scenario 3 lead r...

The quadrupole strength function of 28O is calculated making use of the SIII interaction, within the framework of continuum-RPA and taking into account collisions among the nucleons (doorway coupling). The centroid of the giant resonance is predicted at ≈ 14 MeV, that is much below the energy expected for both isoscalar and isovector quadrupole resonances in nuclei along the stability valley. A...

We discuss the spin dependence of the effective two-body interactions appropriate for three-body computations. The only reasonable choice seems to be the fine and hyperfine interactions known for atomic electrons interacting with the nucleus. One exception is the nucleon-nucleon interaction imposing a different type of symmetry. We use the two-neutron halo nucleus Li as an illustration. We demo...

This paper investigates comprehensive operation and experimentation of an all-optical packet switching router with optical label swapping and reamplification and reshaping (2R) regeneration, capable of multihop operation and Internet protocol (IP)client interoperability. In particular, the experiment demonstrates successful packet switching and transport up to 11 hops with 10 9 bit-error rate a...

The fast, dense winds which characterize Wolf-Rayet (WR) stars obscure their underlying cores, and complicate the verification of evolving core and nucleosynthesis models. Core evolution can be probed by measuring abundances of wind-borne nuclear processed elements, partially overcoming this limitation. Using ground-based mid-infrared spectroscopy and the 12.81μm [Ne ii] emission line measured ...

Subtask scheduling on multi-core is an important direction in the world today. There is little research of dynamic scheduling subtask according to the network traffic prediction. This paper proposes a method of dynamic scheduling of real-time multi-core subtask based on network traffic prediction. According to the prediction result of network traffics, the larger tasks scheduled dynamically int...

Packet classification is the core mechanism that enables many networking services on the Internet such as firewall packet filtering and traffic accounting. Using Ternary Content Addressable Memories (TCAMs) to perform high-speed packet classification has become the de facto standard in industry. TCAMs classify packets in constant time by comparing a packet with all classification rules of terna...

Buffer sizing in Internet routers is a fundamental problem that has major consequences in the design, implementation, and economy of the routers, as well as on the performance observed by the end users. Recently, there have been some seemingly contradictory results on buffer sizing. On the one hand, Appenzeller et al. show that as a direct consequence of desynchronization of flows in the core o...

Programmable routers supporting virtualization are a key building block for bridging the gap between new Internet protocols and their deployment in real operational networks. This article presents the design and implementation of PEARL, a ProgrammablE virtuAl Router pLatform with relatively high-performance. It offers high flexibility by allowing users to control the configuration of both hardw...
