Designing and Implementing IP/MPLS-Based Ethernet Layer 2 VPN Services. An Advanced Guide for VPLS and VLL Designing and Implementing IP/MPLS-Based Ethernet Layer 2 VPN Services. An Advanced Guide for VPLS and VLL

Автор: Zhuo Xu

Год издания: 

A guide to designing and implementing VPLS services over an IP/MPLS switched service provider backbone Today's communication providers are looking for convenience, simplicity, and flexible bandwidth across wide area networks-but with the quality of service and control that is critical for business networking applications like video, voice and data. Carrier Ethernet VPN services based on VPLS makes this a reality. Virtual Private LAN Service (VPLS) is a pseudowire (PW) based, multipoint-to-multipoint layer 2 Ethernet VPN service provided by services providers By deploying a VPLS service to customers, the operator can focus on providing high throughput, highly available Ethernet bridging services and leave the layer 3 routing decision up to the customer. Virtual Private LAN Services (VPLS) is quickly becoming the number one choice for many enterprises and service providers to deploy data communication networks. Alcatel-Lucent VPLS solution enables service providers to offer enterprise customers the operational cost benefits of Ethernet with the predictable QoS characteristics of MPLS. Items Covered: Building Converged Service Networks with IP/MPLS VPN Technology IP/MPLS VPN Multi-Service Network Overview Using MPLS Label Switched Paths as Service Transport Tunnels Routing Protocol Traffi c Engineering and CSPF RSVP-TE Protocol MPLS Resiliency – Secondary LSP MPLS Resiliency – RSVP-TE LSP Fast Reroute Label Distribution Protocol IP/MPLS VPN Service Routing Architecture Virtual Leased Line Services Virtual Private LAN Service Hierarchical VPLS High Availability in an IP/MPLS VPN Network VLL Service Resiliency VPLS Service Resiliency VPLS BGP Auto-Discovery PBB-VPLS OAM in a VPLS Service Network


IP, Ethernet and MPLS Networks. Resource and Fault Management IP, Ethernet and MPLS Networks. Resource and Fault Management

Автор: Andre Perez

Год издания: 

This book summarizes the key Quality of Service technologies deployed in telecommunications networks: Ethernet, IP, and MPLS. The QoS of the network is made up of two parts: fault and resource management. Network operation quality is among the functions to be fulfilled in order to offer QoS to the end user. It is characterized by four parameters: packet loss, delay, jitter or the variation of delay over time, and availability. Resource management employs mechanisms that enable the first three parameters to be guaranteed or optimized. Fault management aims to ensure continuity of service.


Synchronous Ethernet and IEEE 1588 in Telecoms Synchronous Ethernet and IEEE 1588 in Telecoms

Год издания: 

This book addresses the multiple technical aspects of the distribution of synchronization in new generation telecommunication networks, focusing in particular on synchronous Ethernet and IEEE1588 technologies. Many packet network engineers struggle with understanding the challenges that precise synchronization distribution can impose on networks. The usual “why”, “when” and particularly “how” can cause problems for many engineers. In parallel to this, some other markets have identical synchronization requirements, but with their own design requirements, generating further questions. This book attempts to respond to the different questions by providing background technical information. Invaluable information on state of-the-art packet network synchronization and timing architectures is provided, as well as an unbiased view on the synchronization technologies that have been internationally standardized over recent years, with the aim of providing the average reader (who is not skilled in the art) with a better understanding of this topic. The book focuses specifically on synchronous Ethernet and IEEE 1588 PTP-based technologies, both key developments in the world of synchronization over the last 10 years. The authors address the needs of engineers and technical managers who are struggling with the subject of synchronization and provide an engineering reference for those that need to consider synchronization in NGN. The market applications that are driving the development of packet network synchronization and timing architectures are also discussed. This book provides a wide audience with everything they need to know when researching, implementing, buying and deploying packet synchronization architectures in telecommunication networks. Contents 1. Network Evolutions, Applications and Their Synchronization Requirements. 2. Synchronization Technologies. 3. Synchronization Network Architectures in Packet Networks. 4. Synchronization Design and Deployments. 5. Management and Monitoring of Synchronization Networks. 6. Security Aspects Impacting Synchronization. 7. Test and Measurement Aspects of Packet Synchronization Networks. Appendix 1.Standards in Telecom Packet Networks Using Synchronous Ethernet and/or IEEE 1588. Appendix 2. Jitter Estimation by Statistical Study (JESS) Metric Definition.

Год издания: 

Industrial Ethernet ist schon heute fester Bestandteil eines industriellen Netzwerkes. Durch die Echtzeitfahigkeit von PROFINET wird Ethernet nun auch der Standard fur die Anbindung von Feldkomponenten und Antriebstechnik. Damit das von Buroanwendungen gepragte Ethernet auch industrietauglich wird, mussen industrielle Anforderungen wie Verfugbarkeit, Echtzeitfahigkeit und Robustheit erfullt werden. Dieses Buch vermittelt Anlagenplanern und -betreibern, Programmierern und Inbetriebsetzern die Grundlagen und Begriffe fur den Einsatz von Ethernet-LAN-Techniken in der Industrieautomatisierung mit SIMATIC. Die Autoren beschreiben neben Grundlagen und Projektierung auch die Diagnose eines TCP/IP basierten Netzwerkes sowie die Fokusthemen wie IT Security und Wireless-Anwendungen. Au?erdem wird auf die aktuellen Komponenten und Ubertragungsmedien in der SIMATIC eingegangen. So erhalt der Leser einen schnellen und praxisnahen Einstieg in das Thema. 2. Auflage, (Titel der 1.
