無線網路技術的蓬勃發展為未來的網路使用帶來了新的契機和服務模式,且隨著技術的進步普及於生活中。而各種不同的應用也逐漸由有線網路移植到無線網路的環境上,在這當中,即時多媒體應用如:線上電影及音樂、線上會議……等更是不可避免的趨勢。
為了有效率地使用無線網路的頻寬並減少不必要的浪費,利用多點傳播(Multicast)和網際網路群組管理IGMP來傳輸頻寬需求較大的多媒體串流,在未來將是不可或缺的技術,然而,如同釵h網路協定一般,欲在無線網路的環境中使用,皆會面臨了使用者之行動管理和網路頻寬控制二大議題。
在本論文中,提出了新的架構和新的M&M(Mobile and Multicast)協定,其整合了802.11f IAPP,並且只需在AP上實作。在新的架構下,使用者可在intra-subnet及inter-subnet的環境下做handoff時,藉由AP間彼此交換訊息,減少多點傳播資料串流的中斷,讓使用者能繼續享有高品質的服務。除此之外,本論文亦利用訊息交換的機制,保留了服務品質保證(Quality of Service, QoS)參數傳遞的空間,讓未來針對QoS議題所提出的相關研究,能利用該參數的傳遞,加速頻寬的管理與控制(如預先頻寬保留、進入野i控制……等),以提供如多媒體串流等服務的品質保證。
最後,本論文所提的架構能和目前網路上的協定如IGMP、Mobile IP及IAPP等共存,而不需要加以更改,以提供一簡單、具有彈性且容易實作的新架構。
With the advent of wireless and mobile technology, wireless communication is becoming more and more popular in human life. Moreover, real-time multimedia services like music and movies will indeed become important applications in wireless network.
In order to achieve higher bandwidth utilization and reduce unnecessary bandwidth waste, using multicast and IGMP to deliver high bandwidth required multimedia stream would be a trend in the future. However, they also face two important issues when used in wireless network: user mobility management and bandwidth control.
We propose a new protocol called M&M (mobile and multicast) protocol to support mobile multicast of multimedia content delivery service in wireless LANs. It is an extension of the IEEE 802.11f Inter-Access Point Protocol (IAPP) protocols and is intended to be implemented in access points. Under the new architecture, users can enjoy multimedia streaming service without interruption when roaming between APs in wireless access networks. The proposed M&M protocol supports both Intra-subnet and Inter-subnet roaming. Moreover, the proposed protocol supports the exchange of the QoS parameters of user’s subscribed service between APs to assure quality of service of the multimedia content delivery. Our protocol interworks with existing IGMP and Mobile IP as well IEEE 802.11 IAPP without modification. It is simple, flexible, and easy to implement.
