The document discusses the infrastructure for the FIBRE-BR testbed facility using RNP's backbone network. It proposes using a "virtual backbone" with logical topologies over the physical topology to provide dedicated resources for experiments. This would allow multiple experiments to run simultaneously without interference. Each experiment could select its own resources like servers and interfaces. Physical limitations require using the same equipment but virtualizing resources.

This document discusses IPv6 transition strategies for service providers. It begins by noting that the IANA pool of IPv4 addresses has been exhausted and regional registries will soon run out as well. While existing IPv4 networks will continue to function, many devices and applications only support IPv4, creating an "IPv4 long tail" that will be challenging to transition to IPv6. The document then evaluates options for service providers, including dual-stack, translators, and tunnels. It provides more detail on implementing a dual-stack infrastructure in the core network using protocols like IS-IS, OSPF, and BGP. 6PE and 6VPE are introduced as options to provide IPv6 connectivity over an IPv4 MPLS
The document proposes a solution for scaling LDP-based pseudowire (PW) services across multiple regions. It uses LDP signaling for setting up intra-region PWs and BGP for inter-region stitching and routing. The solution allows PW services to extend across autonomous systems and areas without requiring protocols like BGP on terminating provider edges (T-PEs). Provisioning and signaling are simplified through the use of attachment identifiers and route targets. Existing T-PE capabilities are largely reused through minor extensions to FEC-128/129 signaling over LDP. BGP routing between switching provider edges (S-PEs) avoids a full mesh of LDP sessions to improve scaling as the number of T-

Rafał Szarecki - PIM-tunnels and MPLS P2MP as Multicast data plane in IPTV a...PROIDEA
The document discusses two customer case studies using multicast data plane technologies for IPTV and MVPN applications. For Customer A, plain IP multicast with PIM was used, which allowed for ACTIVE-ACTIVE protection only on specific topologies. Traffic restoration depended on IGP convergence and PIM signaling. For Customer B, MPLS P2MP LSPs were used, allowing for ACTIVE-ACTIVE protection on any topology. MPLS capabilities provided bandwidth reservation and faster ~50ms traffic restoration compared to PIM which relied on full protocol convergence. Both solutions are commercially deployed but MPLS P2MP provided better control and restoration characteristics for the large scale of Customer B's network.

BGP Error Handling - Developing an Operator-Led Approach in the IETF (UKNOF 18)Rob Shakir
This document discusses developing an operator-led approach to improving BGP error handling in the IETF. It outlines a four-point approach: 1) avoiding sending BGP NOTIFICATION messages when possible, 2) recovering routing information base (RIB) consistency after errors, 3) restarting BGP sessions hitlessly to reduce impact, and 4) introducing additional monitoring to improve visibility of error handling. The goal is to define how BGP is used in service provider networks, provide operator requirements, and tie together relevant IETF work items to make BGP more robust. Challenges addressed include protocol inconsistencies caused by error responses, achieving RIB synchronization, and balancing manageability against added complexity.
This document discusses developing an operator-led approach to improving BGP error handling in the IETF. It describes common BGP failures seen by network operators, such as erroneous AS_PATH data and very long AS paths causing session failures.

It discusses the timeline and goals of the FIBRE project, describes the current infrastructure including wireless nodes, virtual machines, and connections to other testbeds. It also outlines usage examples, the growth in users, and next steps to upgrade the architecture and expand partnerships.
The FIBRE project is a testbed for experimenting with future internet technologies funded through an EU-Brazil coordinated call. It consists of multiple research institutions and networks that have deployed local testbeds ("islands") connected through a federated network. A new governance model has been established with steering committees, a network operations center, and technical committees to coordinate development and user support. Future plans include expanding to more institutions, integrating new software frameworks, and using the testbed for educational purposes and computer network classes.
FIBRE (legacy) testbed is an experimental platform for networking research and education built on infrastructure from the FIBRE project and operated as a service by the Brazilian NREN. It aims to be integrated with major worldwide testbeds. Data protection, isolation of data flows between users, and portability of experiment data and results are key requirements to attract industry usage. Future plans include deploying new control software, training materials, and thematic "islands" for wireless, IoT, programmable networks and cloud experimentation.
Using Future Internet testbeds in the classroomFIBRE Testbed
The document discusses using the Future Internet testbed FIBRE to teach networking classes. It provides an overview of FIBRE, including its goals of experimenting with new Internet architectures, worldwide initiatives in teaching with testbeds, and plans to develop exercises and lessons to deploy in FIBRE. The summary highlights that FIBRE allows researchers to validate new proposals for the Future Internet through experimentation in its large-scale facilities, and that developing educational materials for its use can help train the next generation of networking researchers.
The document discusses the evolution and current state of FIBRE, a large-scale Future Internet testbed spanning Brazil and Europe. FIBRE originally aimed to design, implement, and validate a shared testbed for experimentation. It now includes 10 nodes in Brazil and 3 in Europe. The testbed is federating internationally and within Brazil to support more experimental projects. It interconnects to networks in Europe and the US through virtualized slices on production OpenFlow backbones at RNP in Brazil and AmLight in the US. This allows experimental facilities while maintaining production network stability and availability.
Pilot Use Case 3: BoD services over the intercontinental FIBRE infrastructureFIBRE Testbed
The document describes a demonstration of bandwidth on demand services over an intercontinental fibre infrastructure using an enhanced version of the Ofelia Control Framework. Key points:
- The demo uses physical switches and servers from the i2CAT FIBRE island controlled by an enhanced NOX controller to create a dedicated slice.
- An enhanced version of the OSCARS platform runs on this slice to provide bandwidth on demand services by composing circuits across the network topology and setting up flows in the switches using the NOX controller.
- The demo shows how an administrator can allocate a physical slice and how OSCARS abstracts this to allow dynamic circuit composition between hosts while ensuring bandwidth, time, and VLAN constraints are met.
The FIBRE project created a federated experimental infrastructure connecting 10 institutions in Brazil and 3 in Europe for Future Internet research. It designed and implemented a shared research facility between Brazil and Europe to support joint experimentation. The infrastructure included programmable network islands at each location interconnected through a control plane and data plane. Several technology pilots were developed to demonstrate capabilities like seamless mobility, high quality video streaming, and bandwidth on demand services. The project provided valuable experience for both European and Brazilian partners in testbed design, federation, and international collaboration on Future Internet research.

The document discusses SDN for network operators. It describes how SDN can help simplify network management by extracting network functions from individual network devices and centralizing them in an SDN controller. This allows the network to be programmed and automated as a single entity rather than through individual device configurations. The SDN controller would use standard interfaces like OpenFlow to discover network resources, provision requests across multiple vendors and domains, and monitor network performance. This unified approach could help reduce complexity compared to today's system of many proprietary network management systems.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

FIBRE-BR Testbed Service Premises
• Service should be simple to deploy and operate in the environment of PoP
operators, and easy to use by project researchers and end users
• Preferably the complexity should be left on the FIBRE-BR side of the island of
the demarcation point
• Implementation in RNP backbone PoPs should not require tools or
processes that demand significant amount of investment in human
resources for its operation

13. FIBRE-BR Experiments requeriments
The FIBRE-BR should allow
• Perform networking experiments in parallel (how many?)
− (There cannot be any interference or conflicts between
experiments)
• Each experiment should be allowed to choose resources: servers,
interfaces etc.
• Each experiment should be allowed to define the network topology (?)*
• Acess to control of selected resources
• Allow acess to measurements and statistics from the experiment
• Some facility to reproduce each experiment
13
13
14. FIBRE-BR Backbone requeriments and some questions
• Should allow communication in Layer 2 between 10 islands of
resources in geographically dispersed end sites in Brazil
• Some questions:
• How important is the High Availability (HA) for this infrastructure?
• Reminder: backbone links failures do happen.
14
14
15. FIBRE-BR Backbone requeriments and some questions (cont.)
• Some questions (cont.):
• Does the FIBRE-BR should allow to each experiment to “build” its own
topology “mapped over” (strict) the physical RNP backbone paths?
• In other words, is there a need to allow each experiment to define it’s own
logical network topology “in sync” with the physical backbone topology?
15
15
16. Questions About Experiments Topologies
• Actual CMFs do not allow automatic control to create arbitrary network
topologies
• Physical topology (physical backbone) x Logical topology (logical FIBRE
backbone)
• Knowledge of the geographic locations of each island wouldn’t be
enough for each experiment (at least in the initial project phase)?
• Does the presence of OpenFlow switches in RNP PoPs of the "physical
backbone" which does not have connected islands can change any
requerement of the physical or logical topology of FIBRE experiments?
16
16
17. Questions About Experiments Topologies (cont.)
Some facts:
• The offering of automatic definition and configuration of a arbitrary
topology for each experiment will demand efforts in development - make
changes - in some actual CMF
• Up to where was possible to verify, this capacity is not offered in any
testbeds environment in production nowadays (this affirmation can
require a confirmation from experts)
17
17
18. Questions About Experiments Topologies (cont.)
Complexity x Pragmatism
• Is it really necessary for the FIBRE to offer automatic arbitrary topology
configuration geographically in sync with the physical backbone topology
for the experiments since day one?
− What kind of experiments would require this capability?
− To obtain what kind of results?
18

19. Proposal for FIBRE-BR Network Architecture
Proposal: Deploy the FIBRE Backbone in phases
• Phase 1 - Deploy a "full mesh" topology using VPLS interconecting all PoPs
that connect FIBRE-BR islands
• Phase 2 - Extend Phase 1 topology to an “hybrid topology”, with some
circuits with explicitly defined paths over the physical RNP backbone,
allowing some “determinism” in part of the FIBRE-BR topology
• Phase ...
• Phase “N” - Deploy a CMF with capability to control all FIBRE and
experiments topologies automatically.

20. Proposal for the FIBRE-BR Backbone
Proposal for Phase 1
Deploy a "full mesh" topology using VPLS to
interconect all FIBRE-BR islands
20
20
21. FIBRE Testbed Facility (cont.)
Option 1
• 1 or 2 dedicated physical 1GigE downlink interfaces from Juniper’s routers to dedicated box
(router or switch) in the PoPs that connect FIBRE islands
• Interconnection of all interfaces in 1 or 2 L2 networks using VPLS (MPLS Virtual Private LAN
Service)
• The VPLS can be configured in two fashions:
− “Loose”: the interconnections of end nodes using MPLS not necessarily will go through
specific paths over the physical layer backbone and can be rerouted dinamically in case
of a physical layer topology failure (H.A.)
− “Strict”: the interconnections of end nodes using MPLS will go through explicitly defined
paths over the physical layer backbone and can be rerouted dinamically in case of a
physical layer topology failure (H.A.)
Option 2
• Use of Juniper JUNOS Logical Systems feature
• 1 or 2 dedicated VPLS Layer 2 networks between logical systems’ interfaces
