  Podstawowym celem artykułu jest przedstawienie i przebadanie sposobu podziału opóźnienia end-to-end dla danego strumienia pakietów wzdłuż łączy ścieżki, tak aby wolne zasoby przydzielane były w sposób gwarantujący jakość, a jednocześnie miała miejsce na tej ścieżce maksymalizacja liczby przyjętych do obsługi strumieni pakietów. Proces ten może dotyczyć zarówno łańcucha domen jak i łańcucha łączy. Opisany model LSS oparty jest na...

  W pracy wykazano, że ostatnie prace komitetów IEEE 802.1 i 802.3 znacznie przybliżyły realizację koncepcji Ethernet End-to-End. Wskazano, że o ile problemy skalowalności zostały w dużej mierze rozwiązane, o tyle inne zagadnienia związane m.in. z niezawodnością i zarządzaniem wymagają jeszcze dużego wysiłku standaryzacyjnego. Jednakże niektóre przedstawione w pracy propozycje IEEE są już na ukończeniu i możliwość realizacji sieci...

  - Bulletin of the Polish Academy of Sciences-Technical Sciences - Year 2012

  End-to-end call setup delay is one of the most important grade of service (GoS) parameters for VoIP networks with Session Initiation Protocol (SIP). A typical subscriber wants to have a connection established as soon as possible. From the operator's perspective call setup time is also crucial because he needs to know how probability of successful packet transmission on SIP links is related to a call setup delay. Then he can make...

  The most important GoS parameter for networks with SIP protocol is end-to-end call setup delay. So far there were no coherent models allowing calculation of these parameters for networks with SIP protocol. Few models were developed but they are insufficient. In the paper we propose model which allows end-to-end call setup delay calculation for networks with SIP protocol. The model is using chain of M/G/1/K models and is applicable...

  Calculating the stator end-winding leakage inductance, taking into account the rotor, is difficult due to the irregular shape of the end-winding. The end-winding leakage may distribute at the end of the active part and the fringing flux of the air gap. The fringing flux belongs to the main flux but goes into the end-winding region. Then, not all the magnetic flux occurring in the end region is the end-winding leakage flux. The...
