....in the most efficient way. Uppgjord (ven faktaansvarig om annan) Prepared (also subject responsible if other) Nr No. This deliverable is organised as follows. Section 2 describes the network topology. Section 3 gives a brief summary of the framework for IP QoS and mobility presented in [KaRe00]. Furthermore, it as example, it emphasises the QoS architectures used in UMTS and Bluetooth. Section 4 presents various solutions on the QoS and mobility between various IP subnetworks that are using different wireless technologies. The protocols used to support the mobility solutions are the ....

....section presents the IP QoS schemes used in the UMTS and Bluetooth technologies. Moreover, the IP mobility scheme based on Mobile IP is briefly presented. 3. 1 Framework for IP QoS and mobility The framework for IP QoS and mobility used in this investigation is based on the framework presented in [KaRe00]. Applying this framework to the network architecture depicted in Figure 2 9 a QoS functional decomposition, see Figure 3 1, is obtained. The architecture depicted in Figure 3 1 consists of three major building blocks: Hosts, local Access Networks, and a Diffserv Core Network. Hosts represents the ....

....of the framework, its entities, and protocols is given in Section 3. Section 4 describes an example of the Framework architecture operation. Finally the conclusions are given in Section 5. Note that the details of the framework and related issues presented in this paper can be found in [20]. 2. IP QOS AND MOBILITY The framework we propose relies on interworking between the current IP QoS architectures, i.e. Integrated Services (Intserv) and Differentiated Services (Diffserv) and the protocols supporting IP mobility. In this section we give an overview of the IP QoS architectures ....

....requires that the Internet next generation architecture will have to be very flexible and open, capable of supporting all these different types of networks, terminals and applications. Furthermore, it can be seen that existing QoS management architectures (such as OSI QoS, QoS A, OMEGA, etc. see [20] for a description of these architectures) are optimized to operate efficiently in small access networks. It is therefore reasonable to consider that a framework should provide the opportunity to support efficient local access QoS management architectures. Furthermore, regarding the QoS solutions ....

....and RESV messages. PATH and RESV messages carry out the basic operation of RSVP. The rest of the RSVP messages are used to either provide information about the QoS state or to explicitly delete the QoS states along the communication session path. The RSVP messages and their functions as given in [KaRe00] are listed in Table 2.2.1 1. All RSVP messages are sent through the network as raw IP datagrams with the protocol number 46, and PATH, PATH Tear and RESV Conf should be sent with the router alert option set [RFC2113] Open REPORT 11 (97) Uppgjord ( ven faktaansvarig om annan) Prepared (also ....
