net neutrality - not! traffic shaping and traffic policing When someone demands "net neutrality", they usually mean that the network must not discriminate between applications being carried in IP packets; that identical transmission characteristics (throughput, delay, number of errors, etc.) are to be provided for all packets regardless of what is being carried in them. They claim (correctly) that this is not the case at present, that the network service provider is "throttling" certain applications, "slowing down" or "shaping" traffic (the correct term is "policing") and that this, in their opinion, must stop. This video tutorial explains Service Level Agreements, traffic profiles, transmission characteristics, and how Differentiated Services (Diff-Serv) is implemented to be able to provide different transmission characteristics for different kinds of traffic - the EXACT OPPOSITE of net neutrality. It is taken from Teracom's DVD video V9 Understanding Voice over IP 2: Voice Packetization • Voice Quality • Codecs, Jitter and Packet Loss • Diff-Serv • Network QoS with MPLS Tags: net neutrality IP network throughput delay throttling slowing shaping traffic policing Service Level Agreements profiles

Teracom DVD Video V4 Understanding Networking 1 - preview Preview of V4 Understanding Networking 1 from Teracom Training Institute http://www.teracomtraining.com DATE: May 15 2007 TYPE: Tutorial, DVD URL: http://www.teracomtraining.com/teracom-overview-v4.htm RELEASE INFO: This course builds on the basic packet, frame and IP networking concepts of Course V3, Fundamentals of Datacom and Networking, to put in place a solid understanding of protocol stacks, the OSI model and layers and IP addressing including address classes, static vs. dynamic public vs. private and network address translation. In Part 3, we move to the next higher level of knowledge, understanding packet networks and bandwidth on demand services from telecommunication service providers. After understanding the core concepts, including virtual circuits, we use the grand-daddy of packet services, X.25 to explain jargon: connection-oriented vs. connectionless and reliable vs. unreliable packet networks. Then we progress through technologies: Frame Relay, ATM and finish with MPLS. We'll trace the flow of TCP and IP packets from server to client across Frame Relay, then see how the same TCP/IP works over MPLS. IP over MPLS will end up replacing all other services including ISDN, T1s, Frame Relay, native ATM. Understanding the OSI layers, how a protocol stack works and TCP/IP over MPLS is career-enhancing knowledge. Course outline - V4: Understanding Networking 1 Length 127 minutes.
