“…Lee et al [44] propose a routing algorithm for SDN with SR that can meet the bandwidth requirements of routing requests. To conclude, a comprehensive survey of the SRv6 use cases can be found in the survey [45]. Among all works cited in this survey, a considerable number focuses on SRv6 deployment in NFV/SDN scenarios.…”

The Segment Routing (SR) architecture is based on loose source routing. A list of instructions, called segments can be added to the packet headers, to influence the forwarding and the processing of the packets in an SR enabled network. In SRv6 (Segment Routing over IPv6 data plane) the segments are represented with IPv6 addresses, which are 16 bytes long. There are some SRv6 service scenarios that may require to carry a large number of segments in the IPv6 packet headers. Reducing the size of these overheads is useful to minimize the impact on MTU (Maximum Transfer Unit) and to enable SRv6 on legacy hardware devices with limited processing capabilities that could suffer the long headers. In this paper we present the Micro SID solution for the efficient representation of segment identifiers. With this solution, the length of the segment list can be drastically reduced.

“…Software Resolved Networks (SRNs) is a new SDN architecture recently proposed for IPv6 enterprise networks [129] [130]; further details about the implementation are provided in the Section V. The network is managed by a logically centralized controller which interacts with the end-hosts through an extended DNS protocol: applications are allowed to embed traffic and/or path requirements in their requests and the controller is able to return the appropriate path to the applications satisfying their needs. SRv6 is used as data plane technology to steer the traffic on a specific path according to the network policies.…”

“…O kernel do Linux já apresenta suporte a roteamento por segmento sobre IPv6 desde a versão 4.10, porém com apenas poucas opções de processamento, como encaminhamento e envio e recebimento de pacotes rotulados. [Duchene et al 2018] utilizaram o arcabouço eBPF para tornar a criação e especificação de novos segmentos mais genérica e flexível. Por meio da adição de novas funções auxiliares, os autores extenderam o kernel do Linux para permitir a implementação de segmentos na forma de programas eBPF.…”

Extended Berkeley Packet Filter (eBPF) has been rapidly adopted across multiple systems since its introduction in the Linux kernel in 2014. eBPF is used for fast packet processing. The use cases of eBPF have grown rapidly to include network monitoring, network traffic manipulation, load balancing, system monitoring, and so on. Several companies already use eBPF on projects such as Facebook, Netronome, and Cilium. This short-course aims to present eBPF. eBPF allows programming network devices. The developer can write in P4 or C language and then compile for eBPF instructions. The eBPF code can be processed in the Linux kernel or by programmable devices such as NetFPGAs and smart-NICs. This short-course covers the main theoretical and fundamental aspects of eBPF, as well as introducing the reader to simple practical activities that can give insight into the general operation and use of eBPF. ResumoO filtro de pacotes estendido (Extended Berkeley Packet Filter (eBPF)) foi rapidamente adotado em vários sistemas desde sua introdução no kernel do Linux em 2014. O eBPF é utilizado para processamento rápido de pacotes. Os usos do eBPF cresceram rapidamente para incluir monitoramento de rede, manipulação de tráfego de rede, balanceamento de carga, monitoramento do sistema, etc. Várias empresas já utilizam eBPF em projetos como o Facebook, Netronome, Cilium. Este minicurso tem como objetivo apresentar o eBPF. O eBPF permite a programação dos dispositivos de redes. O desenvolvedor pode escrever em linguagem P4 ou C e depois compilar para instruções eBPF.
