BuST: Budget Sharing Token protocol for hard real-time communication

Time Properties of the BuST Protocol under the NPA Budget Allocation Scheme

“…Due to space limitations, we do not present the details of FDDI and FDDI-M. More information can be found in [7,6].…”

“…In [7], the authors showed that, when using the Proportional Allocation (PA) scheme, BuST outperforms FDDI and FDDI-M in the service of real-time traffic. In order to extend this previous work, in this paper we analyze the performance of BuST in managing both real-time and non real-time traffic, using the Normalized Proportional Allocation (NPA) scheme to allocate the node budgets.…”

“…Instead, as we will see in Section 4.2, FDDI-M cannot deliver non real-time traffic under the NPA scheme. For further details on FDDI and FDDI-M problems see [7,6].…”

“…BuST [7] is a token passing protocol recently introduced to improve the communication service provided by classic token protocols employed in the FDDI and FDDI-M networks. The BuST protocol differs from FDDI and FDDI-M in how each node exploits the bandwidth saved during the round trip of the token, if any, to deliver asynchronous traffic.…”

Token Passing Techniques for Hard Real-Time Communication

“…For a complete survey, an interested reader can see (Zhang et al, 2004) for TTP; (Chan et al, 1997) and (Daoxu et al, 1998) for MTTP; (Franchino et al, 2007), and (Franchino et al, 2008a) for BuST. In the following, we compare the schemes performance under the token passing protocols considered in this chapter.…”
