Modern networking environments’ dynamic and unpredictable nature poses significant challenges for traditional design approaches and off-the-shelf machine learning methods. As networked systems adapt to changing conditions, such as topology shifts, complex constraints, and unforeseen scenarios, they often outpace the capabilities of conventional solutions. In this panel, we will advocate for a cross-disciplinary approach that integrates insights and techniques from both networking and machine learning and will showcase two recent approaches that exemplify this ethos.

Seminar Topic:
Discrete optimization in queueing systems by reinforcement learning vs random search method.

Speaker: Dmitry Efrosinin, Doctor of Sci. Math., Professor, Acting Head of the Institute for Stochastics of the Johannes Kepler University Linz, Austria.

Abstract:

The topic of the paper is to discuss the application of reinforcement learning algorithms to discrete optimization problems in queueing theory. As a concrete example, we consider the problem of optimal allocation of customers between servers in a multichannel queueing system with a finite population, a common queue, and heterogeneous servers with the aim of minimizing the average cost per unit of time. To verify the experimental results of optimal control obtained, a dynamic programming algorithm is used. Moreover, we have additionally applied an alternative numerical random search method based on the simulated annealing algorithm. A discussion of the advantages and disadvantages of the methods used as well as the peculiarities of their use for controlled queueing systems is carried out.

Moreover, the following problems are discussed in brief:

1. Formulation of the optimization problem as a Markov or semi-Markovian controlled process
2. Reinforcement learning algorithms based on state action value function Q
3. Reinforcement learning algorithms based on the policy gradient.
4. Principles of the simulated annealing.

Аннотация:
В последние годы активно развиваются приложения, требующие гарантированно низких задержек и высокой надежности при доставке данных. Многие современные технологии связи предлагают специализированные механизмы для обслуживания трафика таких приложений. Для настройки этих механизмов и работы алгоритмов управления ресурсами необходимо быстро и точно оценивать эффективную емкость системы -- максимальный объем трафика, обслуживаемого при условии удовлетворения строгим требованиям к качеству обслуживания.
Доклад будет посвящен разработке искомой приближенной формулы для оценки эффективной ёмкости системы многосерверной системы массового обслуживания в условиях, характерных для сценариев сверхнадежной связи с малыми задержками. Будут обсуждаться точность, асимптотическое поведение и применимость полученных соотношений.

Title:System programming and technologies for creating trusted systems (including artificial intelligence)

Abstract:

The widespread adoption of information technologies (including artificial intelligence) is accompanied by a growing number of challenges in the field of cybersecurity. To respond to them, it is necessary to develop appropriate methods and technologies of system programming. The report examines emerging threats and emphasizes the need to create end-to-end technologies that ensure the entire life cycle of development and operation of systems with a given level of trust. Attention is also paid to organizational models for the development of relevant technologies ‒ using the examples of the Center for System Software Security Research and the Research Center for Trusted Artificial Intelligence, created at the ISP RAS. The results of the work of these centers and proposals for the further development of the scientific and technological basis of the IT industry are also presented.

The single most important new fact about the human condition is that we are now all suddenly connected. Since October 29, 1969 the Internet has reached more than five billion people. This wave of connectivity has had its pathologies, but it has also reversed the growth of extreme poverty. And now the megabit Internet is being upgraded to offer gigabit connectivity. All this happened in just 50 years. Buckle up!

Vint Cerf (Internet evangelist at Google and co-inventor of the Internet, Turing award laureate) and Bob Metcalfe (Internet pioneer, Ethernet inventor, 3Com founder, Turing award laureate) will discuss their vision about Internet architecture and services evolutions, such as (but not limited to) the Digital Object Architecture, Knowledge Robots (in the context of current AI Agents), the Interplanetary Internet, and the general concept of National and International Information Infrastructure. This discussion will conclude with a Q&A session with Bob and Vint.

The report is based on a recently published brochure with the same title (V.M. Fomichev, M.: Prometheus, 2020, 66 p.).
Historical material on cryptography is presented, summarizing the dynamics of cryptography development from ancient times to the present day. The tasks of information protection, solved with the help of cryptography, including in the financial and banking sphere, are indicated. The connection of cryptography with other sciences: mathematics, physics, linguistics is shown.
In addition, some urgent tasks of modern cryptography are outlined
1. Multiplication of key material.
2. Standardization of cryptographic protocols in the Russian Federation.

The main goal of the author is to present the role of cryptographic methods of information protection in countering the attacks of intruders in cyberspace.
