Abstract: A method and system for controlling a plurality of sub-pipes in a computer network is disclosed. The computer network includes at least one switch. The plurality of sub-pipes utilizes the switch for transmitting traffic through the network. The method and system include allowing a minimum flow to be set for each of the plurality of sub-pipes and determining whether congestion exists for the pipe. The method and system also include controlling a flow in a sub-pipe of the plurality of sub-pipes only if congestion exists. Once congestion is determined to exist, the time set to control of sub-pipes is set significantly longer than for control over individual decreases or increases of the flows in sub-pipes. The flow is controlled such that the flow for the sub-pipe may be linearly increased if the flow for the sub-pipe of the plurality of sub-pipes is less than the minimum flow. The flow is also controlled such that the flow for the sub-pipe of the plurality of sub-pipes is exponentially decreased if the flow is greater than the minimum flow. In determining whether to increase or decrease the flow in a sub-pipe, a second definition of congestion may be used. Thus the traffic through the switch is stable.

Abstract: A method and systems for optimizing Asymmetric Digital Subscriber Line (ADSL) connections in DSL Access Multiplexor (DSLAM) that marries benefits of G.dmt and G.lite standards, using a flexible method implemented on a programmable Digital Signal Processor (DSP) and a Network Processor (NP) is disclosed. It provides a means to support full G.dmt rates for any of the attached users as long as less than half the users are actively moving data through the DSLAM, but by only using half the digital signal processing hardware and half the power consumption for the line drivers. The invention allows doubling the number of,ADSL ports available over a conventional scheme given about 20% more power is under 50% with only half the respective connections, all those G.dmt rates possible on their exceeds 50%, gradually active G.lite rates based on either based on a tiered tariff structure, until ultimately, when the utilization reaches 100%, all subscribers will be forced back to a maximum rate afforded by G.lite. Only as utilization drops back off, will active subscribers be brought back up to G.dmt's maximum transmission rates. Once the utilization drops below 50% again, then all active subscribers will be able to utilize G.dmt's maximum transmission rates. budget. When the utilization subscribers active on their users experience the maximum wire. However, when utilization subscribers start to experience a fixed policy or one that is based on a tiered tariff structure, until ultimately, when the utilization reaches 100%, all subscribers will be forced back to a maximum rate afforded by G.lite. Only as utilization drops back off, will active subscribers be brought back up to G.dmt's maximum transmission rates. Once the utilization drops below 50% again, then all active subscribers will be able to utilize G.dmt's maximum transmission rates.
