Transport protocol behavior and energy-saving potential
- …Abstract — We investigate the energy-saving potential of transport protocols. We seek an answer to strategic issues of maximizing energy and bandwidth exploitation, without damaging the dynamics of multiple-flow equilibrium. We claim that (i) an energy-saving strategy of the transport level needs to…

The Interaction between Window Adjustment Strategies and Queue Management Schemes
- …Abstract. In this paper, we investigate extensively the joint network dynamics with different AIMD window-adjustment parameters on end-hosts, and different queue management schemes (i.e. DropTail vs. RED) in routers. We reveal that with DropTail buffer, although smooth TCPs causes less queuing-delay…

Less Impact Better Service (LIBS): A Service Paradigm for Internet Telephony
- …We discuss a new packet service paradigm, called ’Less Impact Better Service ’ (LIBS). In simple terms, LIBS primarily schedules packets based on the delay they cause and cancels service differentiation policies when the cumulative delay caused by prioritization becomes significant for non- prioriti…

Exploiting Energy-Saving Potential in Heterogeneous Networks
- …We investigate the energy-saving potential of transport protocols. We seek an answer to strategic issues of maximizing energy and bandwidth exploitation, without damaging the dynamics of multipleflow equilibrium. We claim that (i) an energy-saving strategy of the transport level needs to be associat…

A Study of Deploying Smooth- and Responsive- TCPs with Different Queue Management Schemes
- …While there exist extensive research works on congestion control and active queue management, or the joint dynamics of a congestion control strategy with the Random Early Detection (RED) algorithm, little has been done on the interactions between different window adjustment strategies and different …

Contention-Adaptive Retransmission Timeout
- …We show that TCP timers, based solely on RTT estimations and measurements, cannot capture with precision the level of flow contention. We notice that increased contention may stabilize RTT variation, minimize the deviation and, in turn, shorten the timeout. We show that this behavior is undesirable …

Differentiating Services with Non-Congestive Queuing (NCQ
- …Abstract—We discuss a new packet service paradigm, called ’Less Impact Better Service ’ (LIBS), which is realized through a novel queuing discipline, called ’Non-Congestive Queuing ’ (NCQ). NCQ prioritizes small packets when conditions permit, and utilizes service thresholds to confine the delay imp…
