BSNL Broadband Happy Hour Scheduler

BSNL Broadband

Having used BSNL Home 500 plan at one point of my stint with BSNL DataOne I have also faced the usual dilemma; i.e. when to start the downloads during the Happy Hours (aka time period when the downloads are not counted) and then stop it so that i don’t get billed for excessive use and can stay with the limit of 1GB(or was it 1.5GB ?).

It involved using getting up at nights around 2.30AM and starting the downloads. Later that shifted to Task Scheduler of Windows XP then to a scheduler plugin of Azureus and then to the default scheduler of uTorrent.

A n00bs guide to QoS

Posted by 7sins||33 Comments

Quality of Service

QoS or Quality of Service as is defined by Wikipedia states :

In the field of computer networking and other packet-switched telecommunication networks, the traffic engineering term quality of service (QoS) refers to resource reservation control mechanisms rather than the achieved service quality. Quality of service is the ability to provide different priority to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow. For example, a required bit rate, delay, jitter, packet dropping probability and/or bit error rate may be guaranteed. Quality of service guarantees are important if the network capacity is insufficient, especially for real-time streaming multimedia applications such as voice over IP, online games and IP-TV, since these often require fixed bit rate and are delay sensitive, and in networks where the capacity is a limited resource, for example in cellular data communication.

In layman’s term QoS is the process by which you set some pre-defined rules which determines which data packets are to be allowed first based on their priority level.
