A possible approach to solve this would be a cloud-native network, upon which containerized network functions could be deployed: this is why Kubernetes is gaining attention among network software vendors and service providers. Kubernetes has become the de-facto industry standard for orchestrating containerized resources at real-life scales. However, Kubernetes ’s abilities might seem to be limited. Currently, it lacks the toolset for advanced L2/L3 level networking, which would be essential, for example, in the case of IPv6-based mobility management. Furthermore, many types of software architectures can be envisioned on the top of Kubernetes which may have different impacts on performance. This paper examines different microservice approaches in the context of Mobile IPv6 and Proxy Mobile IPv6, including their service automation capabilities. We evaluate them from functional and performance perspectives and provide statements about their usability in mobile networks.}, year = {2023}, pages = {217-221}, orcid-numbers = {Leiter, Ákos/0000-0003-1323-6541} } @inproceedings{MTMT:34033292, title = {GitOps and Kubernetes Operator-based Network Function Configuration}, url = {https://m2.mtmt.hu/api/publication/34033292}, author = {Leiter, Ákos and Hegyi, Attila and Kispál, István and Böősy, Pál and Galambosi, Nándor and Tar, Gábor Zsolt}, booktitle = {NOMS 2023-2023 IEEE/IFIP Network Operations and Management Symposium}, doi = {10.1109/NOMS56928.2023.10154212}, unique-id = {34033292}, year = {2023}, pages = {1-5}, orcid-numbers = {Leiter, Ákos/0000-0003-1323-6541} } @article{MTMT:33879816, title = {TeleDAL: a regression-based template-less unsupervised method for finding anomalies in log sequences}, url = {https://m2.mtmt.hu/api/publication/33879816}, author = {Horváth, Gábor and Mészáros, András Gergely and Szilágyi, Péter}, doi = {10.1007/s11227-023-05379-w}, journal-iso = {J SUPERCOMPUT}, journal = {JOURNAL OF SUPERCOMPUTING}, volume = {79}, unique-id = {33879816}, issn = {0920-8542}, year = {2023}, eissn = {1573-0484}, pages = {18394-18416}, orcid-numbers = {Horváth, Gábor/0000-0003-3097-1273} } @article{MTMT:33794293, title = {The Sub-Sequence Summary Method for Detecting Anomalies in Logs}, url = {https://m2.mtmt.hu/api/publication/33794293}, author = {Horváth, Gábor and Kádár, Attila and Szilágyi, Péter}, doi = {10.1109/ACCESS.2023.3266990}, journal-iso = {IEEE ACCESS}, journal = {IEEE ACCESS}, volume = {11}, unique-id = {33794293}, issn = {2169-3536}, year = {2023}, eissn = {2169-3536}, pages = {37412-37423}, orcid-numbers = {Horváth, Gábor/0000-0003-3097-1273; Kádár, Attila/0009-0007-8798-950X} } @article{MTMT:33780195, title = {Closed-loop Orchestration for Cloud-native Mobile IPv6}, url = {https://m2.mtmt.hu/api/publication/33780195}, author = {Leiter, Ákos and Lami, Edina and Hegyi, Attila and Varga, József and Bokor, László}, doi = {10.36244/ICJ.2023.1.5}, journal-iso = {INFOCOMM J}, journal = {INFOCOMMUNICATIONS JOURNAL}, volume = {15}, unique-id = {33780195}, issn = {2061-2079}, abstract = {With the advent of Network Function Virtualization (NFV) and Software-Defined Networking (SDN), every network service type faces significant challenges induced by novel requirements.

This allows deploying user plane instances closer to the end-user: traffic serving can be more effortless, and end-to-end latency can be decreased. Mobile IPv6 can also be divided into control and user plane parts. This article will show what this separation presumably will look like in connection with Mobile IPv6. In a dynamic cloud environment, standard Mobile IPv6 must be part of the overall orchestration flow. This is where Cloud-native Mobile IPv6 comes into the picture. This paper presents how ordinary and cloud-native Mobile IPv6 architectures should be refactored with corresponding signaling flows to fit into the CUPS concept. We also show by measurements the latency budget we can gain using localized user-plane instances to connect to a distributed application.}, year = {2022}, pages = {119-122}, orcid-numbers = {Leiter, Ákos/0000-0003-1323-6541} }
