具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
在通信技术中，IP是网络之间信息传送的协议，可将IP数据包从源设备，传送到目的设备。在将IP数据包从源设备传送到目的设备的过程中，通常基于目的设备的IP地址和路由器的网络传输机制进行IP数据包的传输。
在一方面中，IP规定互联网网络上所有的设备(例如，上述源设备和目的设备)都必须有一个唯一的IP地址。换言之，IP地址与设备存在一一对应关系。IP数据包中都必须包含有目的设备的IP地址，根据数据包中的IP地址将数据包传输至目的设备。其中，互联网网络上的每个设备可以有多个IP地址，但是，每个设备至少有一个唯一的IP地址。
另一方面中，互联网是由许多个网络连接形成的大型网络，如果要在互联网之间传输IP数据包，除了上述的目的设备的IP地址以外还必须有路由器的网络传输机制。通过路由器的网络传输机制可将IP数据包通过多个路由器传输到目的设备。其中，路由器的网络传输机制还可以称为是IP路由传输机制。
图1是根据一示例性实施例示出的一种传输IP数据包的系统架构图。本公开提供的通信方法可以应用于图1所示的通信系统架构图中。如图1所示，源设备(即图中来源计算机)可以基于图1所示的架构发送IP数据包，通过多个路由器将IP数据包传输至目的设备(即，图1中目的计算机)。
图2是根据一示例性实施例示出的一种IP数据包的格式示意图。在相关技术中，IP数据包包含源地址和目的地址，格式如图2所示。包括固定部分，固定部分包括版本，首部长度，区分服务，总长度，标识，标志，片偏移，生存时间，协议，首部检查和，源地址以及目的地址。还包括长度可变的可选字段等。
由此可知，IP数据包在由源设备发送之后，在传输IP数据包的过程中，由路由器对IP数据包进行转发，对于源设备而言，不可知IP数据包的传输路径，且IP数据包在每个路由器上的处理时间无法确定。因此，源设备在发送IP数据包之后，并不能确定IP数据包到达目的设备的时间。
基于此，相关技术中提出，由源设备确定传输IP数据包经过的路由器，并确定，每个路由器处理该IP数据包的相对时间(即具体时间)，进而确定每个路由器发送该IP数据包的时间。
示例性的，IP数据包包括源设备IP地址、目的设备IP地址、用于传输所述IP数据包 的路由器标识以及与路由器标识对应的处理时间。其中可以将用于传输所述IP数据包的路由器标识以路由流表的形式置于IP数据包中。其中在路由流表中包括传输IP数据包的多个路由器地址。如上述，每个路由器地址对应有处理时间，例如，路由流表中包括传输IP数据包的N个路由器地址，则N个路由器地址分别对应有处理时间。路由器地址A，对应第一时间A；路由器地址B，对应第一时间B；……；路由器地址N，对应处理时间N。
在本公开实施例中，IP数据包在源设备发出，根据路由流表中的路由器地址的顺序传输该IP数据包。一种实施方式中，以路由器地址B为例。响应于路由器地址B接收到IP数据包，确定IP数据包中路由器地址B对应的处理时间B，以及下一个路由器地址C。路由器地址B在处理IP数据包后，在处理时间B，发送IP数据包至路由流表中的下一跳(即，下一个路由器地址C)。直到将IP数据包传输至目的地址。
但是，相关技术中，需要严格按照时间要求，在数据包中定义的具体时间发送该IP数据包，对于路由器而言，要求路由器的能力很高。一般情况下，路由器会并行处理很多来自不同设备、不同源地址的数据包，这些数据包也被发向不同设备、不同目的地址。当这个路由器需要同一时刻发送的数据包很多时，这将对路由器的并行处理能力挑战很大。
基于此，本公开提供一种数据包传输方法，通过为转发IP数据包的路由器增加发送IP数据包的时间误差，使得路由器基于发送时间在时间误差的时间范围内发送该IP数据包即可，从而保证IP数据包到达目的设备的精准时间，并且减少了路由器对于处理数据包的压力。
可以理解的是，图1所示的一种传输IP数据包的系统架构图仅是进行示意性说明，无线通信系统中还可包括其它网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括的网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例的无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信 网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。当为车联网(V2X)通信系统时，网络设备还可以是车载设备。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。
