“…Traffic processing in residential gateways has been proposed also in the context of Network Function Virtualization (NFV) [31,32]. An existing NFV infrastructure can employ residential gateways to deploy lightweight Native Network Functions [33] or eBPF data plane programs [34], in order to provide delaysensitive services to the user, while computation intensive services are hosted in the data center of the service operator. This solution offers flexibility in the type and number of network services that can be provided and represents an interesting target platform for the deployment of U-Filter.…”

Given that nowadays users access content mostly through mobile apps and web services, both based on HTTP, several filtering applications, such as parental control, malware detection, and corporate policy enforcement, require inspecting Universal Resource Locators (URLs) contained in HTTP requests. Currently, such filtering is most commonly performed in end devices or in middleboxes. Filtering applications running on end devices are less resource intensive because they operate only on traffic from a single user and possibly leverage a hook at the HTTP level to access protocol data, but it is left to the user whether to execute them. On the other hand, middleboxes present the challenge of ensuring that they lay on the path of all the traffic from any relevant device. Residential gateways seem to be the ideal place where to implement traffic filtering because they forward all traffic generated by the hosts on home(-office) networks. However, these devices usually have very limited computation and memory resources, while URL-based filtering is quite demanding. In fact existing approaches rely on a large database of rules coupled with either deep packet inspection or transparent proxying for URL extraction. This paper introduces U-Filter, a URL filtering solution based on a distributed architecture where a lightweight, efficient URL extraction and policy enforcement component runs on residential gateways, delegating to a remote

“…Even if the proposed modeling approach has been defined with NFV in mind, it can be applied to nonvirtualized network functions (NFs), whether implemented in software or hardware, provided that the implementation and characteristics of the underlying hardware are known. The availability of a unified modeling approach for VNF and NF is instrumental in the integration of middleboxes in an NFV infrastructure [2], which is important in a transition phase and for specific applications where a dedicated or specialized hardware platform is necessary for a specific NF to satisfy performance requirements.…”

<p>This work introduces a methodology for the modelization of network functions focused on the identification of recurring execution patterns as basic building blocks and aimed at providing a platform independent representation. By mapping each modeling building block on specific hardware, the performance of the network function can be estimated in termsof maximum throughput that the network function can achieve on the specific execution platform. The approach is such that once the basic modeling building blocks have been mapped, the estimate can be computed automatically for any modeled network function. Experimental results on several sample network functions show that although our approach cannot be very accurate without taking in consideration traffic characteristics, it is very valuable for those application where even loose estimates are key. One such example is orchestration in network functions virtualization (NFV) platforms, as well as in general virtualization platforms where virtual machine placement is based also on the performance<br />of network services offered to them. Being able to automatically estimate the performance of a virtualized network function (VNF) on different execution hardware, enables optimal placement of VNFs themselves as well as the virtual hosts they serve, while efficiently utilizing available resources.</p>
