CACHE ALLOCATION SYSTEM

Abstract:

Examples described herein relate to a network interface device comprising: a host interface, a direct memory access (DMA) engine, and circuitry to allocate a region in a cache to store a context of a connection. In some examples, the circuitry is to allocate a region in a cache to store a context of a connection based on connection reliability and wherein connection reliability comprises use of a reliable transport protocol or non-use of a reliable transport protocol. In some examples, the circuitry is to allocate a region in a cache to store a context of a connection based on expected length of runtime of the connection and the expected length of runtime of the connection is based on a historic average amount of time the context for the connection was stored in the cache. In some examples, the circuitry is to allocate a region in a cache to store a context of a connection based on content transmitted and the content transmitted comprises congestion messaging payload or acknowledgement. In some examples, the circuitry is to allocate a region in a cache to store a context of a connection based on application-specified priority level and the application-specified priority level comprises an application-specified traffic class level or class of service level.
