Marginal Cost of Computation as a Collaborative Strategy for Resource Management at the Edge

This paper explores an extended applications' cost function to model the willingness of Edge data centres to accommodate additional users in decentralized edge computing environments. By enhancing the Marginal Computing Cost per User (MCU) concept, …

Towards a Comprehensive Approach to Resource and Conflict Management in Cloud-Edge Settings

As the Internet of Things (IoT) gains popularity, the multitude of connected devices accessing computing facilities along the Cloud-IoT continuum has risen rapidly. This growth has prompted an increase in IoT-based applications and the data they …

Towards declarative traffic engineering for guaranteed latency-based forwarding

Cloud-edge applications often require data flows to meet stringent latency requirements, ensuring punctual IP packet delivery within specific time windows. To this end, the guaranteed Latency Based Forwarding (gLBF) approach features per-hop bounded …

dgLBF

The guaranteed Latency Based Forwarding approach features per-hop bounded delays to meet the target latency requirements of data flows based on end-to-end application needs. **dGLBF** introduces a Prolog-based specification of [gLBF](https://link.springer.com/article/10.1007/s10922-022-09718-9) for path selection and delay configuration. The prototype determines paths and delays to meet data flow latency targets, offering a concise and extendable solution to the considered problem.

A declarative reasoning approach to conflict management in Intent-Based Networking

Intent-Based Networking aims to automate network management by allowing users to express desired outcomes rather than manually configuring network resources. For its fulfilment, a user intent should be translated into machine-executable actions, …

Sustainable placement of VNF chains in Intent-based Networking

Intent-based networking (IBN) aims at automatically driving network configurations and operations to fulfil high-level intents specified by infrastructure providers and application operators. Deploying Virtual Network Function (VNF) chains onto the …

Towards declarative intent processing and conflict resolution in IBN

Intent-based networking aims at achieving automated network management by allowing users to express desired outcomes rather than manually configure network resources. In this poster paper, by means of an example, we illustrate our proposal for a …

MultiDIPS

**MultiDIPS** is an extension of [DIPS](https://github.com/di-unipi-socc/dips) that allows to model and process **_multiple_** VNF-based service provisioning intents.

Declarative and Linear Programming Approaches to Service Placement, Reconciled

This article proposes an approach to the data-aware multi-service application placement problem in Cloud-Edge settings. We propose both declarative programming and a Mixed-Integer Linear Programming (MILP) approach to determine eligible placements …

EdgeWise

**EdgeWise** shows a declarative programming and a Mixed-Integer Linear Programming (MILP) approach to determine eligible placements that minimise operational costs and reduce the number of used nodes to contain the amount of data transfers. After assessing the performance of both approaches, it reconcile them into a methodology that combines the best of the two worlds by exploiting a declarative pre-processing step to boost the MILP solver while determining optimal solutions.
