My organisation will soon be implementing video and voice over IP. <br />
I have done some research on QOS and seem to have the layer aspect of it sorted out with CBWFQ and a priority LLQ queue. <br />
<br />
My question is, The core of the network is made up off Cisco 3750 switches. Each subnet has a layer 3 SVI interface on the switch.<br />
<br />
Can I apply the CBWFQ LLQ type configuration on the SVI's and If I did that would I need to worry about any layer 2 QOS configuration?<br />
<br />
Also, any hints and suggestions if using layer 3 qos on the svi's is going about this the wrong way. <br />

Windows Vista is an operating system created by Microsoft as the successor to Windows XP. It was intended for PCs, workstations and laptops, and shares the same code base as its successor, Windows 7. New features included an updated graphical user interface (GUI) and visual style dubbed Aero, a new search component called Windows Search, redesigned networking, audio, print and display subsystems, and new multimedia tools. Vista aimed to increase the level of communication between machines on a home network, using peer-to-peer technology to simplify sharing files and media between computers and devices. Windows Vista included version 3.0 of the .NET Framework, allowing software developers to write applications without traditional Windows APIs.

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.
