Abstract
Schemes that do not explicitly use much information about the
state of networks are briefly surveyed, with the focus on dynamic
alternative routing (DAR), a simple but highly effective routing method
currently planned for the British Telecom Network. State-dependent
routing and how some of the methodology also has bearing on the control
issue are discussed. The problem of dimensioning a network that uses
dynamic routing (i.e. how much capacity is needed and where it should be
put to provide an acceptable performance) is addressed. A practical
example, which refers to routing in an international access network, is
discussed. Some conclusions are drawn on the benefits and drawbacks of
distributed routing
