Abstract
Congestion control is provided in a first telecommunications element by receiving a congestion state for a second telecommunications element coupled to the first telecommunications element. An internal congestion state is set in the first telecommunications element for the second telecommunications element based on the congestion state. The internal congestion state for the second telecommunications element is maintained in the first telecommunications element independently of receiving a disparate congestion state for the second telecommunications element.
Claims14
A method for congestion control in a first telecommunications element, comprising:
- receiving a congestion state for a second telecommunications element coupled to the first telecommunications element;
- setting an internal congestion state in the first telecommunications element for the second telecommunications element based on the congestion state;
- the congestion state and the internal congestion state including a plurality of corresponding levels and the first telecommunications element includes a plurality of disparate congestion state timers corresponding to the levels, the act of independently maintaining the internal congestion state comprising:
- setting a congestion state timer corresponding to the level of the internal congestion state;
- and
- maintaining the internal congestion state during the duration of the congestion state timer;
- and
- maintaining the internal congestion state for the second telecommunications element independently of receiving a disparate congestion state for the second telecommunications element in the first telecommunications element;
- and
- upon expiration of the timer, resetting the internal congestion state for the second telecommunications element based on a last congestion state received by the first telecommunications element for the second telecommunications element.
A method for congestion control in a telecommunications network having a first switch and a second switch interconnected by a link, comprising:
- detecting a congestion state for the link for communications from the first switch to the second switch;
- transmitting the congestion state for the link to the first switch;
- setting an internal congestion state in the first switch for the link based on the congestion state;
- the congestion state and the internal congestion state including a plurality of corresponding levels and the switch includes a plurality of disparate congestion state timers corresponding to he levels, the act of independently maintaining the internal congestion state comprising:
- setting a congestion state timer corresponding to the level of the internal congestion state;
- and
- maintaining the internal congestion state during the duration of the congestion state timer;
- maintaining the internal congestion state for the link in the first switch independently of receiving a disparate congestion state for the link for communications between the first switch and the second switch;
- and
- upon expiration of the timer, resetting the internal congestion state for the link a based on a last congestion state received by the switch for the link.
