Description
节点注册方法及系统、 节点解析方法及系统、 网关 技术领域
本发明涉及异构网络通信技术, 尤其涉及一种节点注册方法及系统、 节点解析方法及系统、 网关。 背景技术
从网络中节点的标识角度看, 现在的以太网和将来的网络是不同的。 当前的以太网,所有的节点都被分配基于 TCP/IP协议的 IP地址,这就意味 着网络中所有的设备都使用相同格式的标识 (ID )和位置符(Loc )。 然后 对于将来的网络, 例如物联网 (IoT ), 与现有网络有所不同, 其中的各个 节点可能是基于不同标识架构的, 并且这些异构标识的设备需要互相通讯。
当异构的标识被集成到一个开放的网络时, 即使两个标识来自不同的 标识模式, 仍然可能会出现标识重复的可能。 这种情况下, 就没有办法区 分两个节点。 如图 1所示, 网络域 Α中的四个节点 ID分别为 00、 01、 02、 03 , 网络域 B中的四个节点 ID分别为 00、 0a、 0b、 0c, 那么, 对于由网络 A和网络 B组成的集成网络域, 其中将会出现两个 ID为 00的节点, 难以 区分。
基于对象标识(OID ) 的异构网络架构可以解决这种标识沖突的问题, 如图 2所示。 图中所有的节点都有各自的标识和位置符, 且分别属于接入 网络 A、 B、 C。 接入网络与核心网相连, 每个接入网络都有不同的标识, 网络 A和网络 B的节点可以直接通讯。 网络 C中的节点通过一个网关间接 接入到核心网。
基于图 2所示的网络架构, 每个网络可以有其自身的标识模式, 并且 每个网络确保自己网络内部节点标识的唯一性, 而不同网络的两个标识是
可能相同的。 图 2 中关键的组件包括 OID 解析服务器 (OID Resolution Server, ORS ), ID注册服务器(ID registry ), 其中, ORS管理所有的 ID 注册服务器, ID注册服务器管理一个接入网络中各节点的标识和位置符。
在提供解析框架服务之前, OID、 标识和位置符需要注册到 ORS和 ID 注册服务器。 图 3提供了两级注册过程, 包括节点注册到 ID注册服务器和 ID注册服务器注册到 ORS, 如图 3所示, 最初, 所有节点的标识和位置符 需要被注册到他们的注册服务器,包括网关也要注册。当节点(如 ID为 001、 Loc为 0x0a2的节点 )直接连到 ID注册服务器( OID为 1.2、 Loc为 0xa05 ) 时,该 ID注册服务器注册节点的标识和位置符对( ID( 001 )- Loc( 0x0a2 ) ); 如果节点(如 ID为 001、 Loc为 0x001的节点)通过网关(ID为 101、 Loc 为 0xa04 )连接到 ID注册服务器( OID为 1.1、 Loc为 OxaOl ) 时, 该节点 的标识和位置符对( ID ( 001 ) - Loc ( 0x001 ) )注册到该网关, 然后该网关 的标识和位置符对( ID ( 101 ) - Loc ( 0xa04 ) ) 注册到该 ID注册月良务器, 并且所有节点的标识和网关的位置符对(如 ID ( 001 ) - Loc ( 0xa04 ) )注册 到该 ID注册服务器。 下一阶段, 每个 ID注册服务器注册他们的位置符和 相应的 OID对(如 OID ( 1.1 ) - Loc ( OxaOl )、 OID ( 1.2 ) - Loc ( 0xa05 ) ) 到 ORS。 然后 ORS可以查找到目标节点属于的 ID注册服务器的位置符。
当完成这些注册后 , 源终端节点便可 居目标标识和目标标识所在的 接入网的 OID来找到目标终端节点, 并与之通信, 图 4为基于 OID的异构 网络的一解析流程的示意图, 如同 4所示, 该流程包括:
步骤①: 源终端节点需要发起与 OID为 1.1的网络中 ID为 001的目标 终端节点的通信。
步骤②: 源终端节点向 ORS查询 OID为 1.1对应的位置符。
步骤③: ORS向源终端节点返回响应消息, 携带 OID为 1.1对应的位 置符为 OxaOl。
步骤④: 源终端节点向位置符为 OxaOl的节点查询目标终端节点 ID对 应的位置符。
步骤⑤: 位置符为 OxaOl的 ID注册服务器向源终端节点返回目标终端 节点 ID对应的位置符 0xa04。
步骤⑥: 源终端节点向位置符为 0xa04 的网关发送用户面消息, 携带 目标终端节点 ID。
步骤⑦:位置符为 0xa04的网关判断目标终端节点 ID是否与自身的 ID 一致, 如果不一致, 通过查询自身存储的注册信息, 将该用户面消息转发 至目标终端节点。
然而, 如果某个接入网 (子网) 中的节点就是采用 OID来标识的, 那 么此时可以理解为一种特殊的异构网络。 如果 I巴此时的 OID标识来当成普 通的标识, 采用现有流程进行节点注册及节点解析, 那么, 将会增加网络 解析的负担, 带来没有必要的注册和查找步骤。 发明内容

下面通过具体实施例对本发明的技术方案作进一步详细说明。 实施例 1
图 11为本发明实施例 1所述的注册流程示意图, 如图 11所示, 本实 施例相比于现有技术减少了注册流程步骤, 即网关不需要注册到 ID注册服 务器, 而是直接注册到 ORS。 具体的:
对于不经过网关直接连接到 ORS 的终端节点 (OID 为 3.1、 Loc 为 0x0a2 ), 该终端节点的标识和位置符(OID ( 3.1 ) -Loc ( 0x0a2 ) )直接注册 到 ORSo
对于通过网关( OID为 2.1、 Loc为 0xa04 )连接到 ORS的终端节点( OID 为 2.2、 Loc为 0x001 ), 首先, 该终端节点的标识和位置符 ( OID ( 2.2 ) -Loc
( 0x001 ) ) 注册到该网关, 该终端节点的标识由 OID标识, 另外, 该网关 的节点标识和位置符(OID ( 2.1 ) -Loc ( 0xa04 ) ) 注册到 ORS, 网关下所 有传感终端节点的标识和网关的位置符注册到 ORS, 包括( OID ( 2.2 ) -Loc
( 0xa04 ) )。 实施例 2
该实施例示出了基于 OID的异构网络的改进的解析流程, 主要体现着 解析的信令流程中不在经过 ID注册服务器。 图 12为本发明实施例 2所述 的解析流程示意图, 如图 12所示, 该流程包括:
步骤①: 源终端节点想发起与 OID为 2.2的目标终端节点的通信。 步骤②: 源终端节点向 ORS发送查询消息, 以查询该 OID为 2.2对应
的位置符。
步骤③: ORS向源终端节点返回该 OID所对应的位置符为 0xa04。 步骤④: 源终端节点向位置 0xa04发送用户面消息, 目标地址的 OID 标识是 2.2;
步骤⑤: 本实施例中, 0xa04是网关的地址, 相应的, 网关收到该消息 后, 判断目标地址的 OID是否等于自己的 OID; 结果不相等, 则通过查询 自己的注册信息, 找到目标 OID ( 2.2 ) 的位置符 0x001。
步骤⑥: 网关向位置 0x001转发该用户面消息。 完成该通信过程。 可以看出, 基于本发明实施例所述的方案, 终端节点的 OID直接注册 到 ORS中, 不需要给子网再分配 OID, 也不再需要 ID解析服务器, 从而 能够节省 ID注册服务器, 并且, 终端节点注册流程和解析流程也简化了部 分步骤, 从而能够减轻网络注册及解析负担。
