RSVP is a Layer 3 signaling protocol that allows reservation of bandwidth for a flow in packet- based networks. However, when the RSVP messages need to travel the Layer 2 devices in the LANs, no bandwidth reservation is made in the Layer 2 devices because these devices (switches, bri[r]
To maintain PSTN-grade quality of voice transmission and call setup in multiservice IP networks supporting both real-time voice transmission and non- real-time data services, real-time tra‰c (such as voice packets) must be identi- fied and marked right from the source. This guarantees t[r]
You can define high-speed transport as any interface higher than T1 speed. Although most people refer to digital signal level 3 (DS-3) interfaces and above as high-speed networks, just as with microprocessors what is considered high speed today will be outdated in the future. It i[r]

Network traffic can be classified by Internet service, source or destination IP address, Internet resource (for example, specific URL designators), user or traffic direction (inbound or outbound). A QoS Policy consists of rules that specify the weights, limits and guarantees t[r]
