提出了一种基于云存储的F-HMIPv6切换协议,引入云存储服务商为可接入路由和移动锚点管理转交地址列表,维护列表中转交地址的唯一性与可用性,可接入路由与移动锚点直接向云存储服务商申请获取转交地址,避免了重复地址检测操作和可接入路由与移动锚点自己维护转交地址列表的负担。该协议还可缩短切换发起消息和快速确认消息的消息长度。分析表明,与标准F-HMIPv6切换协议相比,该协议能有效缩短切换时延,节省网络带宽资源和增加协议实用性。
An efficient F-HMIPv6 protocol based on the cloud storage is proposed in this paper. Cloud storage servicer is introduced to manage care-of address(CoA) list for access router (AR) and mobile anchor point (MAP), and maintain the uniqueness and usability of addresses listed in it. CoA is applied for directly to the cloud storage servicer by AR and MAP, so the address detection operation is avoided, and AR and MAP do not need to maintain the addresses list. The protocol could reduce the length of message handover initiate(HI) and handover acknowledge(HACK). Compared with the standard F-HMIPv6 protocol, the protocol has the significant advantages of reducing the handover latency, saving the network’s bandwidth, and increasing the protocol’s practicability.
