This paper identifies various parametrized dynamic priority queue disciplines from literature which are complete in two class M/G/1 queue. Equivalence between these queue disciplines is established by obtaining non linear transformation in closed form. Motivation behind these completeness and equivalence results is discussed from optimal control perspective. Some comments on global FCFS policy ...

Imagine that the particles in the system are each called either first class or second class. The evolution is the same as before, except that if a second-class particle attempts to go to a site occupied by a first-class particle, it is not allowed to do so, while if a first-class particle attempts to move to a site occupied by a second-class particle, the two particles exchange positions. In ot...

This paper addresses the issue of cell loss and its consequent effect on video quality in a packet video system, and examines possible compensative measures. In the system's enconder, adaptive spectral separation is used to develop a two-layer coding scheme comprising a high priority layer to carry essential video data and a low priority layer with data to enhance the video image. A two-step er...

We investigated the photonic packet switch architecture that enables a high node throughput and provides priority services. Previously, we proposed PBSO (partial buffer sharing with overwriting) method that enables prioritized buffer management to control an optical buffer [1]. The PBSO method is based on a single queue and its complexity is O p , where p is the number of priority classes. PBSO...

We investigate a photonic packet switch architecture that enables a high node throughput and provides priority services. We describe PBSO (partial buffer sharing with overwriting) method that allows control of an optical fiber-delay-line buffer by prioritized buffer management under conditions of synchronous arrival of fixed length optical packets at a packet switch. The PBSO method is based on...

Abstract In recent years, dramatic outbursts have been identified toward massive protostars via infrared and millimeter dust continuum molecular maser emission. The longest lived outburst (>6 yr) persists in NGC 6334 I-MM1, a deeply embedded object with no near-IR counterpart. Using FORCAST HAWC+ on SOFIA, we obtained the first mid-IR images of this field since began. Despite being undetecte...
