IEEE International Conference on Cloud Networking
7–10 November 2022 // Paris, France


Keynote 1:
Tackling “the identity problem”

Radia Perlman

Dell, USA




People mostly assume that “the identity problem” is well-understood, and that, given how long Internet authentication has been deployed, the world must have solved how to do that securely. This talk describes various facets of “the identity problem”; for instance, how does a website get a name, how does a website get a certificate, how does a browser know what to trust to sign certificates, how a human finds a website, how a user acquires a unique name, and how users prove they own their names. Surprisingly, there are unsolved issues with all of these aspects. As with most security problems, some people propose “blockchain” as being able to solve everything.

This talk will describe what aspects of identity and authentication blockchain might address, and compare a blockchain approach with what is deployed today. (Hint: I will argue that blockchain will not be an improvement). If the talk spurs spirited debate throughout the conference, all the better.


Radia Perlman is a Fellow at Dell Technologies.  She is known for inventing much of the routing and bridging technology deployed in today’s networks.  She has also made contributions in network security and cryptography. She is the author of the textbook “Interconnections” (about network layers 2 and 3) and coauthor of “Network Security: Private Communication in a Public world”.

Keynote 2:
Issues in Cloud Security

Charlie Kaufman

Dell, USA




What does it mean for a public cloud to be secure? There’s the traditional concern of protecting services from bad actors on the Internet, but there is also protecting customers from other customers, protecting the cloud infrastructure from malicious customers, and even protecting the Internet from malicious customers. There is also protecting customers from the operator of the cloud infrastructure.

Historically, network security was treated differently on the Internet, where you had to assume there were lots of hostile actors, and on an Intranet, where people (sometimes foolishly) assumed there were none. In recent years, the trend has been to treat all networks as hostile and to design for the worst case. But a cloud network truly is different. By a cloud network, I mean one where all routing components – including the hypervisors hosting untrusted guest software – are under the control of a single administration. In a cloud, the network can filter both what comes into endnodes and what goes out of them. Public clouds, where both other customers and the Internet at large have to be protected from bad actors on the inside, present some unique challenges. This talk looks at some of the challenges and the opportunities in this rapidly evolving space.

Keynote 3:
Cloud deployments of 5G core networks: unleashing the power of private 5G

Nicola di Pietro
Athonet, Italy




5G networks have been conceived to address the needs and requirements of very heterogeneous verticals, proposing mobile networks as a controllable and tunable infrastructural asset for companies, industries, and governmental entities, even when they do not have a telecommunication-oriented vocation or deep expertise. To fully realize such an ambition, private 5G networks should be easily instantiated, operated, managed, and scaled. Cloud environments are a perfect domain to deploy virtualized network functions that support such goals.

This presentation focuses on mobile core network virtualized solutions that allow users to deploy the most advanced and sophisticated 5G networks with Wi-Fi-like simplicity while using any 5G-radio from any vendor. We will present a core network solution that can be deployed on private or public cloud environments and resources to serve the needs of different verticals, lighten and facilitate the network deployment and management, and increase the network’s robustness. On-cloud 5G core network deployments make private 5G affordable, practical, and accessible to all kinds of users, without sacrificing latency, resilience, or control, and with reduced management complexity.

In this keynote speech, we will discuss:

  • The network architecture and the cloud networking technologies that underlie on-cloud solutions.
  • From cloud to edge: distributed 5G core network solutions and cloud-supported “edge connectivity bubbles.”
  • The use cases addressed by these solutions: are take-away lessons and experiences from real-life deployments.

Keynote 4:
Building the Responsible Internet

Paola Grosso
University of Amsterdam,

The Netherlands




In the last years, we are witnessing growing concerns from private citizens as well as governments regarding the trustworthiness of the Internet.  One way to address these questions is to look at the current Internet architecture, and the protocols that govern the data transmission, and change them so that we can have additional transparency, accountability, and controllability.

These three aspects are what we call the TAC triad of a Responsible Internet, an extension of the current Internet that we are currently investigating.

In my presentation I will cover the current research effort in this direction,  and show how moving towards more trustable infrastructures enables data sharing applications and services that comply with the desired security levels of the data owners.

DiSC: Datacenter Neworking Optimization With Distributed Shared Connection

Alain Tchana
Ecole Normale Supérieure de Lyon, France




Due to modularity and scalability considerations, most server applications deployed in a datacenter are based on a multi-tier architecture, which comprises multiple software components running on distinct machines (e.g., a load balancer, the core business logic, and a storage backend). While all of the tiers are typically involved in the processing of external client requests, a significant ratio of the bytes within a response payload are actually emanating from a handful of backend tiers — the remaining upstream tiers are only forwarding and encapsulating/encoding them. This results in suboptimal resource usage on the servers and the network fabric of the datacenter. In this talk, I will introduce Distributed Shared Connection (DiSC), a protocol allowing several tiers within a datacenter to jointly act as endpoints of the same TCP connection. This enables the selective bypass of one or several tiers on the response path, leading to reduced resource consumption. Unlike existing optimizations,
DiSC is (1) flexible — it accommodates arbitrary multi-tier topologies and heterogeneous application-level protocols, (2) fine-grained — it allows multiple tiers to be involved in the generation and emission of a given response message (e.g., to decouple the network path of the response headers and footers from the path of the response body, so that the intermediate tiers can remain aware of both the inbound and the outbound traffic), (3) and non-intrusive — it requires only minor and localized/modular modifications to the code base of legacy applications and is fully transparent for external clients.

IP and Telco Slicing: Challenges and Forthcoming Convergence

Barbara Orlandi
Nokia Bell Labs, France




Telco slicing has been said to be the future of connectivity. It has been much talked about and the object of many research papers advancing the State of the Art on architecture, algorithms, resource optimisation, scheduling, orchestration, scaling, machine-learning based automation, reliability. In this talk, we look at concrete impacts of Telco slicing in an IP world. In particular, we will address the following questions:
– What will change in the IP configuration of your device?
– Can slices be planned dynamically everywhere? How will slice numbers grow?
– Will every entreprise small or big be able to benefit of its own private logical 5G network (Non-Public Network: NPN), its own set of slices?
– Is slicing the answer to every 5G service need?

We will also discuss Slicing versus QoS technologies, as they are frequently intermixed or confused, and how they relates to a Service Level Agreement (SLA).
