Definitions

  • the present invention relates to the field of data transmission technologies, and in particular, to a data transmission method, device and system.
  • ICN Information-centric networking
  • the ICN network has two core data packets, namely an interest package and a content data packet responding to the interest package, referred to as a data package, which contains the data content requested by the interest package.
  • Each ICN node in the information center network stores a Forwarding Information Base (FIB) and a Pending Interest Table (PIT).
  • the FIB is used to query the next forwarding node of the interest packet, and the PIT is used to query.
  • the next transit node of the data packet (the principle is to record the port that receives the interest packet, record the port to the PIT, and the data packet is returned to the data request end according to the original path sent by the interest packet through the port.
  • Each ICN node further includes a Content Store (CS) module.
  • CS Content Store
  • Figure 1 is used as an example to describe the data transmission process in ICN:
  • Step 1 ICN Node 1 sends an interest packet request for the required content.
  • Step 2 After receiving the interest packet, the ICN node 2 cannot provide the required content because the node does not have the requested content, and the ICN node 2 determines to query the FIB table to forward the interest packet to the next node ICN node 3, and In the ICN node 2, the original path, that is, the port on which the ICN node 2 receives the interest packet, is recorded in the PIT table.
  • Step 3 After receiving the interest packet, the ICN node 3 also records the original path into the PIT table. Since the ICN node 3 itself stores the requested content, the PIT table is queried to find the original path as the ICN node 2, and the content is returned to the ICN node 2 in the form of a data packet.
  • Step 4 After receiving the data packet, the ICN node 2 caches the received content, that is, stores it into its own CS module. Then ICN node 2 will query its own PIT table to find the original The path is ICN node 1, and finally the data packet is sent to ICN node 1. This completes a data transfer process.

Description

一种数据传输的方法、设备及*** 技术领域
本发明涉及数据传输技术领域，具体涉及一种数据传输的方法、设备及***。
背景技术
信息中心网络(Information-centric networking，ICN)是以获取信息为核心目的网络。ICN网络有两种核心数据包，分别是兴趣(interest)包和响应该兴趣包的内容数据包，简称data包，该data包中包含兴趣包所请求的数据内容。
信息中心网络中的每个ICN节点都存储有转发信息表(Forwarding information base，FIB)和转发请求表(Pending interest Table，PIT)，FIB用于查询兴趣包的下一个转发节点，PIT用于查询data包的下一个传输节点(其原理是记录接收到interest包的端口，将此端口记录到PIT中，data包就通过此端口按照interest包发送的原路径返回给数据请求端。
每个ICN节点还包括内容存储(Content Store，CS)模块，在data包经过该ICN节点时，ICN节点会自动将此data包存储到CS模块中。
以图1为例描述ICN中的数据传输过程：
步骤1：ICN节点1发送一个interest包请求所需内容。
步骤2：ICN节点2收到interest包后，由于本节点没有所请求的内容，因而无法提供所需内容，ICN节点2将查询FIB表确定将此interest包转发给下一个节点ICN节点3，并且在ICN节点2中将原路径，也就是ICN节点2接收到interest包的端口记录到PIT表中。
步骤3：ICN节点3接收到interest包后，同样记录原路径到PIT表中。由于ICN节点3中本身存储有所请求的内容，则查询PIT表找到原路径为ICN节点2，并把该内容以data包的形式返回给ICN节点2。
步骤4：ICN节点2接收到该data包之后，会把接收到的内容缓存起来，也就是存储到自身的CS模块中。然后ICN节点2会查询自身的PIT表找到原 路径为ICN节点1，最后把data包发送给ICN节点1。由此完成一次数据传输过程。
由此可见，在现有机制中，一个interest包只能请求一个data数据包，这样当interest包很多时，就会浪费大量的传输资源。

具体实施方式
本发明实施例提供一种数据传输的方法，可以通过一个兴趣包请求多个数据内容，提高了资源利用率。以下分别进行详细说明。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图2为本发明实施例中ICN架构的简图。
ICN可以包括多个ICN节点设备，如图2所示，ICN节点根据兴趣包的流向可以作为源设备100、中转设备300和目的设备200。源设备100可以是手机、个人计算机等终端设备，中转设备300可以是路由器、交换机等网络设备，目的设备200可以是服务器，当然，中转设备300也可以是服务器、终端等设备，只要能提供中转功能的设备都可以成为中转设备，目的设备200也可以是手机、 个人计算机等终端设备，只要是能提供数据内容的设备都可以成为目的设备，源设备100、目的设备200、中转设备300的角色可以互换，只要是其自身具有兴趣包发送功能、数据包转发功能和提供数据内容的能力，都可以在不同的场景中成为源设备、中转设备或目的设备。所述源设备与所述目的设备直接通信连接，或者，所述源设备与所述目的设备通过所述中转设备间接通信连接。
所述源设备响应于用户输入的兴趣请求，生成帧格式的兴趣包，所述兴趣包包括兴趣标识集合，所述兴趣标识集合用于指示获取用户感兴趣的至少两个数据内容；
所述源设备发送所述兴趣包，所述兴趣包直接到达所述目的设备或经由所述中转设备到达所述目的设备，所述兴趣标识集合用于指示所述目的设备向所述源设备返回所述至少两个数据内容中的部分或全部；
所述源设备接收所述至少两个数据内容。
所述兴趣标识集合包括至少两个兴趣标识，所述至少两个兴趣标识与所述至少两个数据内容一一对应；
所述至少两个兴趣标识用于指示所述目的设备向所述源设备返回与每个兴趣标识对应的数据内容。
所述兴趣标识集合包括兴趣标识和所述与兴趣标识对应的数据内容的开始位置标识和结束位置标识；
所述兴趣标识、所述开始位置标识和所述结束位置标识，用于指示所述目的设备向所述源设备返回从所述开始位置标识所指示的位置开始到所述结束位置标识所指示的位置结束的与所述兴趣标识对应的至少两个数据内容。
本发明实施例中，兴趣标识可以是用户感兴趣的文件名称，文件编号，内容名称等。
本发明实施例中，兴趣包的帧格式可以参阅表1进行理解：
表1：兴趣包的帧格式
Figure PCTCN2015086729-appb-000001
如表1所示，Name表示所请求内容的名称，Selectors选择标识位，Nonce： 随机值，用于唯一标识一个兴趣包，Scope：控制兴趣包的传播范围，也就是跳数限制；Interes Life time：传播生命周期。
本发明实施例中在兴趣包中添加多个平行的Name，那么目的设备在接收到兴趣包后将根据兴趣包的多个Name设置返回与每个Name对应的多个数据内容。
本发明实施例中，兴趣包所请求的多个数据内容可以在同一个目的设备上，也可以在不同的目的设备上，参阅图3，本发明实施例中以兴趣包所请求的多个数据内容在同一个目的设备上为例说明本发明实施例中数据传输的过程：
S105、源设备生成兴趣包。
假设兴趣包的帧格式中有三个Name标识位，每个标识位的文件名分别为：Name1、Name2和Name3。
例如：三个文件名分别为：/sport/football/book/section1，/sport/football/book/section2和/sport/football/book/section3。分别表示与足球相关的书籍的第一章、第二章和第三章。
当然，兴趣包中也可以包含两个或更多的Name标识位，只要根据用户需求平行扩展即可。
S110、源设备向目的设备发送生成的兴趣包。
S115、目的设备根据兴趣包中的三个文件名，分别查找三个文件名各自对应的数据内容。
实际上，接收到数据包后，目的设备先确定三个数据内容是否都在本节点上有存储，本发明实施例是以三个数据内容都存储在本节点上为例进行说明的，所以，目的设备直接查找到了三个数据内容。
S120、目的设备向源设备返回三个数据内容。
数据内容的返回可以是以数据包的形式返回的，可以分多个包持续传输。
本发明实施例中，源设备与目的设备之间可能有多个转发设备，图3中没有画出，但并不代表源设备与目的设备一定是直接通信的，当然，源设备与目的设备之间可以直接通信。
而且，兴趣包在传输时在所经历的各个ICN节点是有记录原始路径的，数据内容返回时也按照原路径返回，具体的记录过程可以参阅图1现有技术的描述中FIB表和PIT表的方式进行理解。
实际上，兴趣包所请求的多个数据内容可能不在同一个目的设备上，参阅图4，下面以兴趣包所请求的三个数据内容在两个目的设备上为例进行说明：
S205、源设备生成兴趣包。
假设兴趣包的帧格式中有三个Name标识位，每个标识位的文件名分别为：名称1、名称2和名称3(Name1、Name2和Name3)。
例如：三个文件名分别为：/sport/football/book/section1，/sport/football/book/section2和/sport/football/book/section3。分别表示与足球相关的书籍的第一章、第二章和第三章。
当然，兴趣包中也可以包含两个或更多的Name标识位，只要根据用户需求平行扩展即可。
S210、源设备向第一目的设备发送兴趣包。
S215、第一目的设备确定本节点只存储有名称1对应的数据内容，则查找到名称1对应的数据内容。
S220、第一目的设备向源设备返回名称1对应的数据内容。
S225、第一目的设备生成新的兴趣包，新的兴趣包中包含名称2和名称3。
S230、第一目的设备向第二目的设备发送新的兴趣包。
S235、第二目的设备查找名称2和名称3对应的数据内容。
本发明实施例中，以名称2和名称3对应的数据内容都在第二目的设备上为例进行说明，当名称2或名称3对应的数据内容不在第二目的设备上时，第二目的设备可以继续生成，并向其他目的设备发送兴趣包，直到所有的数据内容都查找到。
S240、第二目的设备向第一目的设备返回名称2和名称3对应的数据内容，第一目的设备再向源设备转发名称2和名称3对应的数据内容。
本发明实施例中，源设备与第一目的设备之间、第一目的设备与第二目的设备之间可能有多个转发设备，图4中没有画出，但并不代表源设备与第一目 的设备、第一目的设备与第二目的设备一定是直接通信的，当然，源设备与第一目的设备、第一目的设备与第二目的设备之间可以直接通信。
而且，每个兴趣包在传输时在所经历的各个ICN节点是有记录原始路径的，数据内容返回时也按照原路径返回，具体的记录过程可以参阅图1现有技术的描述中FIB表和PIT表的方式进行理解。
本发明实施例中通过增强兴趣包的帧结构，扩展兴趣包中Name的数量，从而使得一个兴趣包能够请求多个数据内容，降低了兴趣包的传输量，提高了网络资源的利用率。
上述通过平行扩展名称标识位的方式来实现兴趣包的增强，本发明的另一实施例中，还可以改进兴趣包的Name的格式，使得Name能够包含多个内容的请求。例如：改进后的Name可以为：Name:/HUAWEI/SN/File/％M％content1％content2％content3。
该Name以％M为标志表明后续字符串表示多个内容请求，％content1，％content2，％content3则表示此Name同时请求content1，content2和content3。注意，此处命名的格式只是一个举例，实际的命名格式不受此处举例的限制。
对于这种帧格式的改进，数据传输过程与图3和图4对应的场景实施例基本相同，只是在图4对应的场景下，新的兴趣包中的名称修改为/HUAWEI/SN/File/％M％content2％content3，因为第一目的设备已经返回了content1的相应data包。
本发明实施例通过增强兴趣包的帧结构，扩展Name的含义，从而使得Name域可以包含多个请求内容的名称。因而一个兴趣包能够请求多个data包，降低了兴趣包的传输数量，提高了网络资源的利用率。
本发明的另一实施例中，还可以通过另一种方式改进兴趣包的帧结构，如表2所示，
表1：兴趣包的帧格式
Figure PCTCN2015086729-appb-000002
如表2所示，Range-start和Range-end域表示请求内容的范围，如Name： /sport/football/book/section；Range-start为1；Range-end为10。这种结构表示请求“体育足球书籍章节1到章节10”。注意，此处命名的格式只是一个举例，实际的命名格式不受此处举例的限制。
对于这种帧格式的改进，数据传输过程与图3和图4对应的场景实施例基本相同，只是图4对应的场景实施例中，生成新的interest兴趣包的格式应与此处实施例三的方案一致，即修改此处的Range-start和Range-end的范围，如初始Range-start为1，Range-end为10，在中间节点获取了内容1-3之后，重新生成的interest兴趣包的Range-start为4，Range-end为10。
本发明实施例通过在兴趣包的帧结构，添加Range-start和Range-end域用于补充Name域的信息，从而使得一个兴趣包可以包含多个data包的请求信息，并且请求多个data包。因而一个兴趣包能够请求多个data包，减少了兴趣包的传输量。提高了网络资源的利用率。

301、源设备响应于用户输入的兴趣请求，生成帧格式的兴趣包，所述兴趣包包括兴趣标识集合，所述兴趣标识集合用于指示获取用户感兴趣的至少两个数据内容，其中，所述源设备应用于信息中心网络ICN，所述ICN还包括中转设备和目的设备，所述源设备与所述目的设备直接通信连接，或者，所述源设备与所述目的设备通过所述中转设备间接通信连接。

在上述信息中心网络中的设备的多个实施例中，应当理解的是，在一种实现方式下，发送模块、接收模块可以是由输入/输出I/O设备(比如网卡)来实现，生成模块、查找模块可以由处理器执行存储器中的程序或指令来实现的(换言之，即由处理器以及与所述处理器耦合的存储器中的特殊指令相互配合来实现)；在另一种实现方式下发送模块、接收模块可以是由输入/输出I/O设备(比如网卡)来实现，生成模块、查找模块也可以分别通过专有电路来实现，具体实现方式参见现有技术，这里不再赘述；在再一种实现方式下，发送模块、接收模块可以是由输入/输出I/O设备(比如网卡)来实现，生成模块、查找模块也可以通过现场可编程门阵列(FPGA，Field－Programmable Gate Array)来实现，具体实现方式参见现有技术，这里不再赘述，本发明包括但不限于前述实现方式，应当理解的是，只要按照本发明的思想实现的方案，都落入本发明实施例所保护的范围。
本实施例提供了一种信息中心网络中的设备的硬件结构，参见图10所示，一种信息中心网络中的设备的硬件结构可以包括：
收发器件、软件器件以及硬件器件三部分；
收发器件为用于完成包收发的硬件电路；
硬件器件也可称“硬件处理模块”，或者更简单的，也可简称为“硬件”，硬件器件主要包括基于FPGA、ASIC之类专用硬件电路(也会配合其他配套器件，如存储器)来实现某些特定功能的硬件电路，其处理速度相比通用处理器往往要快很多，但功能一经定制，便很难更改，因此，实现起来并不灵活，通常用来处理一些固定的功能。需要说明的是，硬件器件在实际应用中，也可以包括MCU(微处理器，如单片机)、或者CPU等处理器，但这些处理器的主要 功能并不是完成大数据的处理，而主要用于进行一些控制，在这种应用场景下，由这些器件搭配的***为硬件器件。
软件器件(或者也简单“软件”)主要包括通用的处理器(例如CPU)及其一些配套的器件(如内存、硬盘等存储设备)，可以通过编程来让处理器具备相应的处理功能，用软件来实现时，可以根据业务灵活配置，但往往速度相比硬件器件来说要慢。软件处理完后，可以通过硬件器件将处理完的数据通过收发器件进行发送，也可以通过一个与收发器件相连的接口向收发器件发送处理完的数据。
本实施例中，收发器件用于发送兴趣包和接收数据内容。
硬件器件及软件器件的其他功能在前述实施例中已经详细论述，这里不再赘述。
下面结合附图就发送模块、接收模块可以是由输入/输出I/O设备(比如网卡)来实现，生成模块、查找模块可以是可以由处理器执行存储器中的程序或指令来实现的技术方案来做详细的介绍：

通过I/O设备730接收所述至少两个数据内容。
与现有技术中一个兴趣包只能请求一个数据内容相比，本发明实施例提供的ICN中的设备，可以通过一个兴趣包请求多个数据内容，提高了资源利用率。
处理器710控制信息中心网络中的设备70的操作，处理器710还可以称为CPU(Central Processing Unit，中央处理单元)。存储器750可以包括只读存储器和随机存取存储器，并向处理器710提供指令和数据。存储器750的一部分还可以包括非易失性随机存取存储器(NVRAM)。具体的应用中信息中心网络中的设备70的各个组件通过总线***720耦合在一起，其中总线***720除包括数据总线之外，还可以包括电源总线、控制总线和状态信号总线等。但是为了清楚说明起见，在图中将各种总线都标为总线***720。
上述本发明实施例揭示的方法可以应用于处理器710中，或者由处理器710实现。处理器710可能是一种集成电路芯片，具有信号的处理能力。在实现过程中，上述方法的各步骤可以通过处理器710中的硬件的集成逻辑电路或者软件形式的指令完成。上述的处理器710可以是通用处理器、数字信号处理器(DSP)、专用集成电路(ASIC)、现成可编程门阵列(FPGA)或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件。可以实现或者执行本发明实施例中的公开的各方法、步骤及逻辑框图。通用处理器可以是微处理器或者该处理器也可以是任何常规的处理器等。结合本发明实施例所公开的方法的步骤可以直接体现为硬件译码处理器执行完成，或者用译码处理器中的硬件及软件模块组合执行完成。软件模块可以位于随机存储器，闪存、只读存储器，可编程只读存储器或者电可擦写可编程存储器、寄存器等本领域成熟的存储介质中。该存储介质位于存储器750，处理器710读取存储器750中的信息， 结合其硬件完成上述方法的步骤。
