Establishing Network Quality of Service for a Virtual Machine

Abstract: A system and method for implementing a VM to identify a data packet for transmission, the data packet including a QoS the data packet is to receive as compared to another QoS that another data packet is to receive The system and method further includes a SNIC to pull the data packet from the VM based upon the QoS the data packet is to receive The system and method may also include a link scheduler module to transmit the data packet based upon the QoS the data packet is to receive The system and method may also include a receiver to receive a management instruction from a network management device, the management instruction to dictate the QoS the data packet is to receive based upon a SLA

On the Importance of a VoIP Packet

Abstract: If highly compressed multimedia streams are transported over packet networks, losses of individual packets can impair the perceptual quality of the received stream in different degrees, depending on the content and context of the lost packet. In this paper, we investigate the impact of individual packet loss on the perceptual speech quality in Voice-over-IP systems using three popular coding types and receiver-side loss concealment algorithms. We set up a testing environment to measure the impairment of individual packet losses and define an appropriate quality metric. We evaluate published algorithms on packet loss quality prediction (DTX, Source-Driven Packet Marking and SPB-DiffMark) and identify their strengths and weaknesses. The quality of a VoIP telephone call can be enhanced significant, if a precise packet-loss quality model decides for each VoIP packet, how it should be forwarded throughout the network.

Radio communication device and semiconductor integrated circuit device used for the same

Abstract: A semiconductor integrated circuit for a radio communication terminal sequentially uses a plurality of frequency channels by instructions from a hopping frequency decision unit to receive packet data by a reception unit. When the integrated circuit cannot detect the head of the packet data in reception operations, the integrated circuit cannot receive packet data should be received originally then assumes that the received packet data is a packet error. And the integrated circuit calculates packet error rates for each frequency channel on the basis of the number of times of reception operations performed for each frequency channel and of the number of times of packet errors to estimate channel qualities by using the packet error rates.

Connection admission control strategy and routing considerations in multimedia (non-geo) satellite networks

Abstract: This paper investigates the strategy that has to be adopted for connection admission control and handoff execution in dynamic satellite networks that use on board satellite fast packet switching as part of a mobile broadband ISDN network. A new method for admission control and radio resource management in a multispot-beam satellite network is proposed and its performance is examined by a simulation model. The results show that we can implement a flexible connection admission control algorithm in a distributed way that take the user mobility in addition to the service specific parameters in account.
