....In the following, B will always mean the buffer size of an optimal routing algorithm. 1. 2 Previous results The study of adversarial models in communication networks was initiated, in the context of queueing disciplines, by Borodin et al. 12] Other work on adversarial queueing includes [6, 13, 14, 15, 23, 26]. In these papers it is assumed that the adversary has to provide a path for every injected packet and reveals these paths to the system. The paths have to be selected in a way that they do not overload the system. Hence, it only remains to find the right queueing discipline (such as ....

....of successfully delivered packets. However, we will show that the seemingly impossible task is possible, both for anycasting and multicasting. The study of adversarial models was initiated, in the context of switching alone, by Borodin et al. 16] Other work on switching includes [6, 22, 23, 24, 42, 45] In these papers it is assumed that the adversary has to provide a path for every injected packet and reveals these paths to the system. The paths have to be selected in a way that they do not overload the system. Hence, it only remains to find the right queueing discipline (such as ....

....to the system. There is no need to do either routing or admission (input stream) control. Thus, it only remains to find the right switching strategy to send the packets to their destinations. This model was introduced by Borodin et al. in [9] and has subsequently been studied in several papers [5, 12, 13, 14, 17, 18]. All previous results mentioned above (except for a result by Gamarnik for the special case that the adversary reveals the paths to the system [13] only manage to accomplish their task if the injection process is strictly below what can be handled by the network. Or more precisely, it has to be ....

....Growing rank protocol (see [16] In this case every packet is marked with a rank depending on its generation time. The routers always forward the packet with the smallest rank. Furthermore, every time a packet traverses a link, its rank will be increased. ELIS (enforced longest in system, see [19]) This strategy is a restricted variant of the LIS strategy. The strategy uses control packets in order to enforce that the generation times of the packets which are routed across any link are increasing with time. Figure 9 shows a sample output of simulations with different switching strategies ....
