A survey of programmable networks

In this paper we present a programmable networking model that provides a common framework for understanding the state-of-the-art in programmable networks. A number of projects are reviewed and discussed against a set of programmable network characteristics. We believe that a number of important innovations are creating a paradigm shift in networking leading to higher levels of network programmability. These innovations include the separation between transmission hardware and control software, availability of open programmable network interfaces, accelerated virtualization of networking infrastructure, rapid creation and deployment of new network services and environments for resource partitioning and coexistence of multiple distinct network architectures. We present a simple qualitative comparison of the surveyed work and make a number of observations about the direction of the field.

Designing Interfaces for Open Programmable Routers

The ability to rapidly create and deploy new network services and architectures in response to new user demands is a driving force behind the emergence of programmable networks. The goal of open network control is being addressed in the IEEE P1520 Working Group (http://www.ieee-pin.org/) through the definition of a set of open network programming interfaces for networks. These interfaces would allow service providers to manipulate the state of the network through high-level languages and abstractions in order to construct and manage new network services with quality of service support. In this paper, we provide an overview of the IEEE P1520 reference model and a detailed framework for the development of low-level, open programmable interfaces for IP-based router and switch networks.

A usage parameter control for multi-service ATM networks

Discusses a usage parameter control (UPC) mechanism for policing multiple traffic parameters. The authors discuss the requirements for UPC on multi-service ATM networks and propose a data flow diagram that specifies UPC control flow with a function box called UPC templates. A tandem connection of UPC templates is used for specifying multiple-parameter policing. Some examples of UPC actions are given. Applying the proposed data flow diagram, a UPC circuit policing three traffic parameters can be implemented on one LSI and used for subscriber interfaces of up to 155 Mb/s.
