Each SFC is composed of Virtual Network Functions (VNFs), where each VNF performs a specific task. In this work, we tackle two key challenges in deploying SFCs across an LSN. Firstly, we aim to optimize the long-term system performance by minimizing the average end-to-end SFC execution delay, given that each satellite comes with a pre-installed/cached subset of VNFs. To achieve optimal SFC placement, we formulate an offline Dy","authors_text":"Aris Leivadeas, Ioannis Lambadaris, Khai Doan, Marios Avgeris, Wonjae Shin","cross_cats":["cs.SY","eess.SY","math.IT"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.IT","submitted_at":"2024-09-08T08:39:50Z","title":"Cooperative Learning-Based Framework for VNF Caching and Placement Optimization over Low Earth Orbit Satellite Networks"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2409.05025","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:e703d133b7ef98beca244e9af5db625a5844cc18ae869588f14527395262f430","target":"record","created_at":"2026-07-05T09:04:43Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"9213a80aab297a0478dc20b4a1a668244249f2b11d3a1bfa943bfa295225c29c","cross_cats_sorted":["cs.SY","eess.SY","math.IT"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.IT","submitted_at":"2024-09-08T08:39:50Z","title_canon_sha256":"f4faa4a236b725bd77cb57748981fd204158bf2603ebeb1a32bcb2ef272a7b09"},"schema_version":"1.0","source":{"id":"2409.05025","kind":"arxiv","version":1}},"canonical_sha256":"2f6c9d39c2f18230f1265a2a78394796c4e0f90ac3fc1de3db97338193bcc7c1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2f6c9d39c2f18230f1265a2a78394796c4e0f90ac3fc1de3db97338193bcc7c1","first_computed_at":"2026-07-05T09:04:43.085242Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:04:43.085242Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"yYCiCVrVeeUkbHIEtQCv/xFF2xeydNJ66WpCKcO0w4wNevVE7yDGboaOSmFHfvoRpPxP5M5sqNgQ5A+/l3ENDg==","signature_status":"signed_v1","signed_at":"2026-07-05T09:04:43.085649Z","signed_message":"canonical_sha256_bytes"},"source_id":"2409.05025","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e703d133b7ef98beca244e9af5db625a5844cc18ae869588f14527395262f430","sha256:6566c6f5386b90458d4502216b3cd91d83f68b60abe2138a2671b4fb9a619c82"],"state_sha256":"9cde8e1f4f29ec205d29e93ef4a5cf84be136361af48dbe50d33325166cddd90"}
