—Network Functions Virtualization can enable each user (tenant) to define his desired set of network services, called (network) service graph. For instance, a User1 may want his traffic to traverse a firewall before reaching his terminal, while a User2 may be interested in a different type of firewall and in a network monitor as well. This paper presents a(More)
—Packet filtering is a technology at the foundation of many traffic analysis tasks. While languages and tools for packet filtering have been available for many years, none of them supports filters operating on the encapsulation relationships found in each packet. This represents a problem as the number of possible encapsulations used to transport traffic is(More)
—Some recent works propose to extend network devices (e.g., routers) with the possibility to execute additional user-provisioned software operating on the data-plane. This enables network devices to be enriched with new functionalities, potentially decided at run-time directly by the end users. This paper focuses on one of such programmable routing platform(More)
This paper presents a software architecture that can dynamically and transparently establish direct communication paths between DPDK-based virtual network functions executed in virtual machines, by recognizing new point-to-point connections in traffic steering rules. We demonstrate the huge advantages of this architecture in terms of performance and the(More)
