A YANG Data Model for Intermediate System to intermediate System (ISIS) Topology

Individual IETF Internet-Draft - October 2022
NO LONGER ACTIVE DRAFT - This document defines a YANG data model for representing an abstract view of the provider network topology that contains Intermediate System to intermediate System (ISIS) information. This document augments the 'ietf-network' data model by adding ISIS concepts.

Extensions to the Access Control Lists (ACLs) YANG Model

Individual IETF Internet-Draft - October 2022
NO LONGER ACTIVE DRAFT - RFC 8519 defines a YANG data model for Access Control Lists (ACLs). This document discusses a set of extensions that fix many of the limitations of the ACL model as initially defined in RFC 8519.

Instantiation of IETF Network Slices in Service Providers Networks

Individual IETF Internet-Draft - March 2023
Network Slicing (NS) is an integral part of Service Provider networks. The IETF has produced several YANG data models to support the Software-Defined Networking and network slice architecture and YANG- based service models for network slice (NS) instantiation. This document describes the r

A YANG Network Data Model for Layer 2 VPNs

IETF RFC 9291- September 2022
This document defines an L2VPN Network Model (L2NM) that can be used to manage the provisioning of Layer 2 Virtual Private Network (L2VPN) services within a network (e.g., a service provider network).

A Layer 3 VPN Network YANG Model

IETF RFC 9182 - February 2022
As a complement to the Layer 3 Virtual Private Network Service Model (L3SM), which is used for communication between customers and service providers, this document defines an L3VPN Network Model (L3NM) that can be used for the provisioning of Layer 3 Virtual Private Network (L3VPN) services withi

A Common YANG Data Model for Layer 2 and Layer 3 VPNs

IETF RFC 9181 - February 2022
This document defines a common YANG module that is meant to be reused by various VPN-related modules such as Layer 3 VPN and Layer 2 VPN network models.

Multi-layer Transport Network Slicing with Hard and Soft Isolation

2021 Optical Fiber Communications Conference and Exhibition (OFC2021)
We validate the deployment of isolated transport network slices in IP over DWDM network. To this end, an isolated transport network slice is deployed using multi-layer isolation mechanisms based on OpenConfig and ONF Transport API.

Field Trial of Programmable L3 VPN Service Deployment Using SDN-Based Multi-domain Service Provisioning over IP/Optical Networks

2021 - IEEE Network, Vol. 35, Issue 6, November/December 2021
Network operators cannot change their footprint to upgrade the entire network to support SDN from scratch. Hence, network operators adapted the original SDN concept into a hybrid SDN approach to have a pragmatic, evolutionary, and economically viable solution.

Packet Optical Transport Network Slicing with Hard and Soft Isolation

2021 - Applied Sciences, 11(13), 6219
Network operators have been dealing with the necessity of a dynamic network resources allocation to provide a new generation of customer-tailored applications.
