#project 2 for oms6250 # # this defines a switch that can can send and receive spanning tree # messages to converge on a final loop free forwarding topology. this # class is a child class (specialization) of the stpswitch class. to # remain within the spirit of the project, the only inherited members # functions the student is permitted to use are: # # self. switchid (the id number of this switch object) # self. links (the list of swtich ids connected to this switch object) # self. send_message(message msg) (sends a message object to another switch) # # student code must use the send_message function to implement the algorithm - # a non-distributed algorithm will not receive credit. # # student code should not access the following members, otherwise they may violate # the spirit of the project: # # topolink (parameter passed to initialization function) # self. topology (link to the greater topology structure used for message passing) # # copyright 2016 michael brown, updated by kelly parks # based on prior work by sean donovan, 2015
