Abstract: Techniques are disclosed for service-based tunnel selection for forwarding network traffic. In one example, a network device obtains, based on service parameters associated with a network service, a service-specific tunnel selection scheme. The tunnel selection scheme identifies a primary mapping mode for mapping the network service to a primary transport tunnel and fallback mapping modes for mapping the network service to fallback transport tunnels. The primary mapping mode is categorized according to a first type comprising tunnel colorization, while the fallback mapping modes are categorized according to types other than tunnel colorization. In response to determining that the network service cannot be mapped to the primary transport tunnel according to the primary mapping mode, the network device, maps, based on the fallback mapping modes, the network service to the fallback transport tunnels.

Abstract: Systems and methods for supporting inter subnet partitions in a high performance computing environment. In accordance with an embodiment, a fabric manager can define a range of P_Key values, among a plurality of P_Key values, as a inter subnet partition (ISP) P_Key range. The fabric manager can communicate this defined range of P_Key values to a number of subnets, via their subnet managers. The subnet managers in each subnet retain management over their subnets. As there is no central management that configures each side of inter subnet communication, subnet managers on within participating subnets can set up ISP membership, and then exchange information with the other subnet.
