Current implementations of GMPLS protocol suite are unaware of optical signal physical impairments and quality of transmission. In this paper, we present an overview of different approaches for implementing QoT estimation and QoT measurements in transparent networks and for encompassing sparse regeneration information in translucent networks.

Circuit-switched networks are emerging as an attractive alternative to conventional packetswitched ones for some types of application, particularly ones involving transferring a large volume of data. The ESLEA Project will use the UKLight circuit-switched network, and its analogues overseas, to demonstrate the usefulness of circuit-switched networks in several applications disciplines. A circui...

Abstract This document discusses the applicability of various tests for measuring single router control plane convergence, specifically in regard to the Open Shortest First (OSPF) protocol. There are two general sections in this document, the f...

Different kinds of malware like the botnets and the worms are a main threat on Internet for the current and future. Their efficiency to control systems is proved and we are investigating the malware mechanism that can be adapted to get an efficient and scalable management plane. Our work consists in modelling malware based network management and assessing its performance.

The advent of the cooperating IP-enabled heterogeneous radio networks will offer, under the “Beyond 3G” vision, ubiquitous services. In this new challenging context, a novel architecture has been designed within the control plane to avoid modification of existing networks. Therefore, a new entity in the network, a complementary middleware in the terminal, and enhanced signaling protocols were i...

Identifying the network-wide forwarding behaviors of a packet is essential for many network management applications. We present AP Classifier, a control plane tool for packet behavior identification. Experiments show that the processing speed of AP Classifier is faster than existing tools by at least an order of magnitude. Furthermore, AP Classifier uses very small memory and is able to support...

To guarantee network availability and security, operators must ensure that their reachability policies (e.g., A can or cannot talk to B) are correctly implemented. This is a difficult task due to the complexity of network configuration and the constant churn in a network’s environment, e.g., new route announcements arrive and links fail. Current network reachability analysis techniques are limi...

In a transport network scenario, Data Plane connections controlled by either a Generalized Multiprotocol Label Switching (GMPLS) Control Plane (Soft Permanent Connections SPC) or a Management System (Permanent Connections PC) may independently coexist. The ability of transforming an existing PC into an SPC and vice versa -without actually affecting Data Plane traffic being carried over it -is a...

This work presents the design and implementation of an optical transparent IP/WDM network testbed. The implemented software allows the characterization of the transport, control and management planes of the network. Furthermore, it was developed a graphic user network interface for the client/management relation in the optical network. We adopted a centralized the control and management planes,...

Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Abstract This document specifies an ATM-based protocol for communication between ST2+ agents. The ST2+ over ATM protocol supports the matching of one hop in an ST2+ tree-structure stream with one ATM connection. In this docu...
