摘要: Quality of Service (QoS) has become a very important issue in networking, covering many performance aspects and numerous measures. The deployment next generation wireless system includes 2.5G General Packet Radio (Gprs), which is the packet-switched extension Global System for Mobile communications (Gsm), Third-Generation (3G) Universal Telecommunications (Umts) to meet needs larger capacity higher bit rates. AnUmts packet core network an IP-based network. Internet Engineering Task Force (Ietf) Forum developed several IP QoS related mechanisms available transport networks. Management (Sqm), one component Telecommunication Network (Tun), will enable providers manage against objectives set out customer Level Agreements (Slas) customers compare service offerings different providers.
