Network protocols generally implement integrity protection, encryption and authentication as separate validation steps. Since each validation step contributes encoding and processing overhead associated with individual packet transfers over the network, such network protocols can make inefficient use of limited packet space. Systems and methods according to the present disclosure combine integrity protection, encryption and authentication into a single validation step thereby making efficient use of limited packet space.

Combined integrity protection, encryption and authentication

System utilization related to memory usage can be monitored by storing host memory usage information in the corresponding host physical memory. However, retrieving this information can be a high overhead operation because it involves engaging with the operating system of each host. Moreover, storing memory usage information in the host physical memories can pose a security risk if they also store privileged data. Network interfaces according to the present disclosure provide unobtrusive and secure support for monitoring of network and other system resources such as regions of memory within host physical memories. Implementations according to the present disclosure include a plurality of memory region counters stored on a network interface. Each memory region counter corresponds to one of the memory regions located in a physical memory of a host coupled to the network interface. Each of the counters includes a system utilization metric associated with its corresponding memory region.
