Abstract:
1. A method of dimensioning a packet switched communications network that includes a plurality of nodes that are interconnected by a plurality of links, to accommodate committed bandwidths for a plurality of ports that are connected to the packet switched communications network, the method comprising: providing bandwidth in a given link that includes first and second ends, based on a link dimensioning rule that is a function of committed bandwidths from ports that are connected to the first end of the given link and ports that are connected to the second end of the given link; wherein the plurality of ports is a first plurality of ports, the dimensioning also accommodating fixed bandwidths for a plurality of second ports that are connected to the packet switched communications network, the providing bandwidth in the given link comprising: identifying a first sum of committed bandwidths from ports that are connected to the first end of the given link and a second sum of committed bandwidths from ports that are connected to the second end of the given link; and providing bandwidth at the given link that is at least equal to a minimum of the first sum plus a sum of fixed bandwidths from the plurality of second ports that are connected to the first end of the given link, and the second sum plus a sum of fixed bandwidths from the plurality of second ports that are connected to the second end of the given link.
