DEFINE_COS
Chapter 3176
DEFINE_COS
DEFINE_COS adds a class of service definition or modifies a previously
defined COS. The definition specifies TG “rows” and node “rows”, which
associate a range of node and TG characteristics with weights used for
route calculation. The lower the weight the more favorable the route.
VCB Structure
The DEFINE_COS verb contains a variable number of cos_tg_row and
cos_node_row structures; the number of each is specified by the
num_of_node_rows and num_of_tg_rows parameters. The TG rows are
included at the end of the main DEFINE_COS structure, in ascending
order of weight; they are followed by the node rows, again in ascending
order of weight.
