A strategy to manage time sensitive traffic in infiniband

A strategy to compute the InfiniBand arbitration tables

“…As 11 VLs are not allowed, 15 data VLs should be implemented. If the ports do not have enough VLs implemented for this classification, we can map several SLs to a single VL [2].…”

“…For the sake of clarity, we will assume that the network only has DB traffic and we will see how to fill in the table of low priority when the table of high priority is empty. In [2] we extend this proposal for DBTS traffic.…”

“…Although the results for BE and CH traffic are not the focus of this paper, we have reserved slots for these traffic classes in the tables. In this first approach, we have not considered DBTS traffic, but in [2] we present results for DBTS traffic when several mixtures of DBTS and DB traffic are used. Those results show that both kinds of traffic are able to achieve their expected performance.…”

Improving the performance of real-time communication services on high-speed LANs under topology changes

“…This is because the primary and the secondary channels must not share resources in order to maximize fault tolerance. 2 Once both the primary and the secondary channels have been successfully established, the real-time channel establishment process has finished. Otherwise, resources for both the primary and the secondary channels are released, and the real-time channel is rejected.…”

“…To compute the maximum delay, we must consider the maximum delay in each switch times the number of switches crossed by the channel [2]. Figure 1.…”
