Cisco Catalyst QoS: Quality of Service in Campus Networks

End-to-end QoS deployment techniques for Cisco Catalyst series switches Examine various QoS components, including congestion management, congestion avoidance, shaping, policing/admission control, signaling, link efficiency mechanisms, and classification and marking Map specified class of service (CoS) values to various queues and maintain CoS values through the use of 802.1q tagging on the Cisco Catalyst 2900XL, 3500XL and Catalyst 4000 and 2948G/2980G CatOS Family of Switches Learn about classification and rewrite capabilities and queue scheduling on the Cisco Catalyst 5000 Implement ACLs, ACPs, ACEs, and low-latency queuing on the Cisco Catalyst 2950 and 3550 Family of Switches Understand classification, policying, and scheduling capabilities of the Catalyst 4000 and 4500 IOS Family of Switches Configure QoS in both Hybrid and Native mode on the Catalyst 6500 Family of Switches Utilize Layer 3 QoS to classify varying levels of service with the Catalyst 6500 MSFC and Flexwan Understand how to apply QoS in campus network designs by examining end-to-end case studies Quality of service (QoS) is the set of techniques designed to manage network resources. QoS refers to the capability of a network to provide better service to selected network traffic over various LAN and WAN technologies. The primary goal of QoS is to provide flow priority, including dedicated bandwidth, controlled jitter and latency (required by some interactive and delay-sensitive traffic), and improved loss characteristics. While QoS has become an essential technology for those organizations rolling out a new generation of network applications such as real-time voice communications and high-quality video delivery, most of the literature available on this foundation technology for current and future business applications focuses on IP QoS. Equally important is the application of QoS in the campus LAN environment, which is primarily responsible for delivering traffic to the desktop. Cisco Catalyst QoS is the first book to concentrate exclusively on the application of QoS in the campus environment. This practical guide provides you with insight into the operation of QoS on the most popular and widely deployed LAN devices: the Cisco Catalyst family of switches. Leveraging the authors' extensive expertise at Cisco in the support of Cisco Catalyst switches and QoS deployment, the book presents QoS from the campus LAN perspective. It explains why QoS is essential in this environment in order to achieve a more deterministic behavior for traffic when implementing voice, video, or other delay-sensitive applications. Through architectural overviews, configuration examples, real-world deployment case studies, and summaries of common pitfalls, you will understand how QoS operates, the different components involved in making QoS possible, and how QoS can be implemented on the various Cisco Catalyst platforms to enable truly successful end-to-end QoS applications. This book is part of the Networking Technology Series from Cisco Press, which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.

Kann das Pingen von f als Denial-of-Service (DoS) gewertet werden?

Das Pingen von f allein kann normalerweise nicht als Denial-of-Service (DoS) betrachtet werden. Pingen ist eine grundlegende Netzwerkfunktion, die verwendet wird, um die Erreichbarkeit eines Netzwerkgeräts zu überprüfen. Ein DoS-Angriff beinhaltet normalerweise eine große Anzahl von Anfragen, um ein Netzwerkgerät zu überlasten und es unzugänglich zu machen. Das Pingen von f allein ist in der Regel nicht ausreichend, um einen solchen Angriff durchzuführen.

SOA Principles of Service Design

This is the eBook version of the printed book. If the print book includes a CD-ROM, this content is not included within the eBook version.“This book could be described as an encyclopedia of service design–Erl leaves nothing to chance. Indispensable.” –Steve Birkel, Chief IT Technical Architect, Intel Corp.   “An absolute pleasure to read…the best SOA book I’ve read. A book I would recommend to all of my colleagues; it provides much insight to the topics often overlooked by most books in this genre…the visuals were fantastic.” –Brandon Bohling, SOA Architecture and Strategy, Intel Corporation   “This book is a milestone in SOA literature. For the first time we are provided with a practical guide on defining service characteristics and service design principles for SOA from a vendor-agnostic viewpoint. It’s a great reference for SOA discovery, adoptions, and implementation projects.” –Canyang Kevin Liu, Principal Enterprise Architect, SAP Americas, Inc.   “I liked this book. It contains extremely important material for those who need to design services.” –Farzin Yashar, IBM SOA Advanced Technologies   “This book does a great job laying out benefits, key ideas and design principles behind successfully adopting service-oriented computing. At the same time, the book openly addresses challenges, risks and trade-offs that are in the way of adopting SOA in the real-world today. It moves away from ivory-tower views of service orientation, but still lays out a strong vision for SOA and outlines the changes necessary to realize the full potential.” –Christoph Schittko, Senior Architect, Microsoft   “I recommend this book to any SOA practitioner who wishes to empower themselves in making service design real…gives readers the 360º view into service design [and] gives SOA practitioners the depth and understanding needed into the principles of SOA to assist in the design of a mature and successful SOA program.” –Stephen G. Bennett, Americas SOA Practice Lead, BEA Systems   “SOA projects are most successful when they are based on a solid technical foundation. Well accepted and established design principles are part of this foundation. This book takes a very structured approach at defining the core design principles for SOA, thus allowing the reader to immediately applying them to a project. Each principle is formally introduced and explained, and examples are given for how to apply it to a real design problem. A ‘must read’ for any architect, designer or developer of service oriented solutions”. –Andre Tost, Senior Technical Staff Member, IBM Software Group   “There are few references for SOA that give you the nuts and bolts and this one is at the top of the list.
