IP语音系统的位置 影响话音质量的因素 Amount of network delay(300ms round-trip) and jitter (50ms) Sources of delay and jitter include PC endpoints, # of router hops and oversubscription of bandwidth Level of packet loss, especially compressed voice and tones Oversubscription of bandwidth is primary cause Voice compression technology (high compression = lower quality ) QoS strategy and implementation Type of WAN (private or managed IP network typically have better QoS than Internet) Traffic profile: large packets can cause excessive delay for smaller voice packets in converged networks if sent as single units Network Quality of Service Many of IP Telephony’s voice quality issues can be addressed by IP networks that are QoS-enabled QoS-enabled means Switched vs. shared LAN Network devices (switches/routers) can classify traffic types by switch port (802.1p), IP address, TCP/UDP port number, ToS/DiffServ byte Network devices can process different traffic classes differently(typically by placing traffic in queues) Applications (e.g., Definity IP Solutions) can mark packets with indicator (DiffServ, TCP/UDP ports) Network devices can inspect packet, recognize the indicator,and act accordingly Net result is that voice traffic can be handled ahead of other traffic types - reducing or avoiding delay, jitter or packet loss Management Simplification Network is becoming too complex for box-by-box management to be practical Increasingly more integration between applications and infrastructure (e.g., QoS marking and handling) Common store of user, endpoint, application, network information is required More mission-critical (e.g., e-business) applicationsuse network Network behavior needs to be increasingly tied tobusiness policies Drives need for Directory-based policy management systems 毫无顾虑的演进方案 Avaya ECLIPS 新产品线 DEFINITY IP 现已提供的IP应用 业界领先的解决方案： Internet 呼叫中心/CentreVu IP 座席 统一信息系统 Unified Messaging 工作流管理 Workflow Management 客户关系管理 CRM 视频、语音会议系统 C
