Computing in the network

Description of the research topic:

Computing in the network is a new research area that has emerged over the past few years. In-network computing refers to the execution of programs typically running on end-hosts within network devices. The computation in this model is done within the network, using devices that have already been deployed and are already used to forward network traffic. In contrast to traditional network computing where the computation is done by computers deplyoed in a network, the computations are performed by programmable switches. The two key benefits of in-network computing are high throughput and low latency. Nowadays, switch ASICs process up to ten billion packets per second, supporting billions of operations per second per offloaded application. These switches are designed as pipelines, working on streams of packets without stalls. In general, they support sub-microsecond latency with low variance in non-overloaded situations. In in-network computing transactions are terminated within their network path rather than reaching an end-host (e.g. a server). In this way, the latency introduced by the end-host can be saved, significantly reducing the response time. It has recently been demonstrated by existing applications that in many scenarios 10 000 times higher performance can be reached with performing computation in the network compared to their server-based counterparts. During the course of this PhD work we will investigate open questions of this novel paradigm called in-network computing, with special focus on aspects like real-time control, traffic management, reliability and security, and energy efficiency.
