具体实施方式
为了能够更加详尽地了解本发明实施例的特点和技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
在对本发明实施例提供的通信方法进行详细说明之前，先对无线通信网络进行简要说明。
无线通信网络经历了从1G到5G的发展阶段。在无线通信网络发展过程中，整体网络架构基本可以分为三层，包括：核心网、接入网与终端三个层次，层与层之间通过接口进行连接。
在3G网络中，如图1所示，3G网络中的接入网部分叫做UMTS陆地无线接入网(UMTS Terrestrial Radio Access Network，UTRAN)，UTRAN包括一个或多个无线网络子系统(Radio Network Subsystem，RNS)。RNS中的网元包括无线网络控制器(Radio Network Controller，RNC)和节点B(Node B，NB)。核心网(Core Network，CN)中的网元包括移动交换中心(Mobile Switching Center，MSC)、服务支持节点(Serving GPRS Support Node，SGSN)、网关支持节点(Gateway GPRS Support Node，GGSN)。MSC负责语音、短信等电路域业务。SGSN/GGSN负责数据传输等分组域业务。3G网络中的各个网元之间通过Iu接口、Iub接口、Iur接口等固定接口连接。其中，CN和RNC之间通过Iu接口连接，RNC和Node B之间通过Iub接口连接。不同的RNC之间通过Iur接口连接。
在4G网络中，如图2所示，4G网络对3G网络进行了极大的简化，例如去掉了电路域网络架构，合并了部分网元(如RNC和NB)。4G网络中的接入网部分叫做演进的UMTS陆地无线接入网(Evolved UMTS Terrestrial Radio Access Network，E-UTRAN)。 其中，CN中的网元包括移动管理功能(Mobility Management Entity，MME)网元、服务网关(Serving GateWay，S-GW)等。E-UTRAN中的网元包括演进的节点B(evolved Node B，eNB)。4G网络中的各个网元之间通过X2接口、S1接口等固定接口连接。其中，不同的eNB之间通过X2接口连接，eNB和MME/SGW通过S1接口连接。
在5G网络中，如图3所示，5G网络相比4G网络在接入网方面并未有太大变化，但是在核心网方面由于垂直业务和虚拟化的需要，将核心网网元进行了进一步细化，从而形成了新的架构。5G网络中的接入网部分叫做下一代无线接入网(Next Generation Radio Access Networking，NG-RAN)，5G网络中的核心网部分叫做5G核心网(5G Core Networking，5GC)。其中，5GC中的网元包括移动管理功能(Mobility Management Function，AMF)网元、用户平面功能(User plane Function，UPF)网元等。NG-RAN中的网元包括gNB和ng-eNB。5G网络中的各个网元之间通过固定接口连接。其中，gNB(ng-eNB)与AMF/UPF通过NG接口连接，gNB与ng-eNB通过Xn接口连接。
从图1到图3可以看出，网络架构从传统网络架构演进至今，主要由核心网、接入网、终端三部分组成。其中终端对接某一个或者多个相同类型的接入网网元；而接入网在控制面与用户面分别对接一个或者多个相同类型的核心网网元。
然而在未来无线网络中，除了典型的基站作为接入网网元(也称为接入节点)之外，其他类型的接入节点也会被应用起来为用户提供服务，包括可以移动的接入节点和无法移动的接入节点。其中，可以移动的接入节点包括：卫星、飞行器、汽车、移动终端等；不能移动的接入节点包括：基站、固定终端(如路由器、电视机等)，如图4所示。
在以上所有的接入节点中，有的接入节点属于稳定节点，例如基站或者固定终端；有的接入节点属于不稳定节点，例如飞行器、汽车或者移动终端等。终端在进行数据传输时可以通过Uu/侧行链路(Side Link，SL)接口直接与目的网络或者目的终端进行通信，也可以通过两跳甚至多跳与目的网络或者目的终端进行通信。当终端需要进行数据传输时，无论终端数据的目标节点是网络服务器还是其他终端，源终端也会面临着多重路径的选择以及反馈等问题，而终端如何根据业务需求和/或网络配置，选择不同的网络路径进行数据传输尚未定义。例如，在图5所示的未来无线网络中，对于源节点和目标节点，接入节点包括：移动终端、汽车、基站卫星等，在这些接入点之间如何选择源节点与目标节点之间进行数据传输的路径目前尚未定义。
基于上述问题，本发明实施例的技术方案提出了一种通信方法，本发明实施例的通信方法可以应用于未来无线网络。
这里，未来无线网络中进行通信的设备可称为通信设备，其中，发送数据包的通信设备为源节点，源节点发送的数据包的目标通信设备为目标节点，源节点和目标节点之间进行数据传输的路径所经过的通信设备为转发节点。其中，未来无线网络中的接入点可作为为源节点，可作为目标节点，也可作为转发节点。
示例性的，本发明实施例应用的未来无线网络系统可如图4所示，接入点包括：可以移动的接入节点和不能移动的接入节点，可以移动的接入节点包括：卫星、飞行器、汽车、移动终端等；不能移动的接入节点包括：基站、固定终端(如路由器、电视机等)。
其中，图4所示的未来无线网络的核心网采用以下通信系统的核心网长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)通信系统、5G系统或未来的通信系统等。
这里，将未来无线系统中为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信的通信设备称为网络设备。网络设备可以是LTE系统中的eNB，还可以是NR/5G系统中的gNB，或者是云无线接入网络(Cloud Radio Access  Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、通信卫星、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
在一示例中，本发明实施例提供的未来无线网络中的通信设备除了图4所示的接入点之外，还可包括网络控制器、移动管理实体等其他网络实体，本发明实施例对此不作限定。

本发明实施例中的源节点可为终端设备或基站，本发明实施例中的目标节点可为终端设备或基站。

在本发明实施例中，数据包的业务质量要求通过数据无线承载(Data Radio Bearer，DBR)体现，也可以通过业务数据流(Data flow)体现。可选地，不同的DRB ID或者Flow ID对应不同的业务质量要求。其中，DBR是无线侧分配的对应不同业务的数据承载；业务数据流是无线侧对应不同业务的承载方式。
以业务参数为数据包对应的切片为例，根据数据包所属的业务对应的切片即数据包对应的切片选取目标路径。
切片(Slicing)是指网络根据承载业务的自有特征和需求，对端到端的网络资源(网络功能、物理硬件及接口管道资源等)进行逻辑划分和封装，以满足不同业务对网络带宽、时延、可靠性等网络性能的服务质量需求。
可选地，切片的划分可基于业务场景进行划分。例如，增强移动宽带(Enhance Mobile Broadband，eMBB)业务对应的切片为eMBB切片，物联网(Internet of Things，IoT)业务对应的切片为IoT切片，超可靠低延迟通信(Ultra Reliable Low Latency Communications，uRLLC)业务对应的切片为uRLLC切片。
可选地，切片的划分可基于业务类型进行划分。例如，游戏业务对应的切片为切片1，小包业务对应的切片为切片2，打包业务对应的切片为切片3。其中，小包业务指数据包的数量小的业务，比如：即时通信的文本信息；打包业务数据包的数量大的业务，比如：视频流。可选地，数据包的数据量的大小可依据指定阈值来判定，当数据包的数据量大于指定阈值，该数据包属于大包业务，当数据包的数据量小于指定阈值，该数据包属于小包业务。
以业务参数为数据包的业务质量要求和对应的切片为例，根据数据包的业务质量 要求和数据包所属的业务对应的切片即数据包对应的切片选取目标路径。在一示例中，数据包对应的切片为切片1，根据数据包要求的时延和切片1选取目标路径。在一示例中，数据包对应的切片为切片2，根据数据包要求的速率和切片2选取目标路径。在一示例中，数据包对应的切片为切片2，根据切片1和数据包要求的可靠性选取目标路径。在一示例中，根据数据包要求的时延和速率选取目标路径。在一示例中，数据包对应的切片为切片3，根据切片3和数据包要求的时延、速率和可靠性选取目标路径。
可选地，如图7所示，S601可以执行为S6011：基于路径选择规则确定所述目标业务参数对应的目标路径。
可选地，所述路径选择规则包括：业务参数和路径的对应关系，所述业务参数包括以下信息至少之一：业务质量要求或切片。
本发明实施例中，源节点包括有业务质量要求和路径的对应关系或切片和路径的对应关系。

在以业务质量要求为时延，且根据业务质量要求和路径的对应关系确定目标路径为例，时延1对应路径A、时延2对应的路径B、时延3对应路径C；当待传输的数据包要求的时延为时延2，则目标路径为路径B。其中，路径A包括：路径1一条路径，路径B包括：路径2和路径3一条路径，路径C包括：路径4一条路径。
在以业务质量要求为可靠性，，且根据业务质量要求和路径的对应关系确定目标路径为例，可靠性1对应路径A、可靠性2对应的路径B、可靠性3对应路径D；当待传输的数据包要求的可靠性为可靠性2，则目标路径为路径B。
在以业务质量要求包括速率和可靠性，且根据业务质量要求和路径的对应关系确定目标路径为例，速率1和可靠性1对应路径A、速率1和可靠性2对应的路径C、速率2和可靠性1对应路径D、速率2和可靠性2对应的路径E；当待传输的数据包要求的速率为速率1且可靠性为可靠性2，则目标路径为路径C。
以根据切片和路径的对应关系确定目标路径为例，切片1对应路径A、切片2对应路径E、切片3对应路径F，当待传输的数据包对应的切片为切片2，则目标路径为路径E。
本发明实施例中，通过路径选择规则判断通过待传输的数据包的业务参数的类型，以指示待传输的数据包的业务参数为业务质量要求还是切片。
本发明实施例中，不同的业务参数对应不同的路径选择规则。
基于业务参数的类型不同，路径选择规则包括：
路径选择规则1、业务质量要求和路径的对应关系，以根据业务质量要求选取传输待传输的数据包的目标路径；
路径选择规则2，切片和路径的对应关系，以根据切片选取传输待传输的数据包的目标路径。
路径选择规则3，业务质量要求、切片和路径的对应关系，以根据业务质量要求和切片选取传输待传输的数据包的目标路径
当路径选择规则为路径选择规则1，则根据业务质量要求和路径的对应关系，确定待传输的数据包的业务质量要求对应的目标路径。
当路径选择规则为路径选择规则2，则根据切片和路径的对应关系，确定待传输 的数据包对应的切片对应的目标路径。
当路径选择规则为路径选择规则3，则根据业务质量要求、切片和路径的对应关系，确定待传输的数据包的业务质量要求和对应的切片所对应的目标路径。

在一示例中，指示信息为路径选择规则1：业务质量要求和路径之间的对应关系，以指示根据业务质量要求选取传输待传输的数据包的目标路径。
在一示例中，指示信息为路径选择规则2：切片和路径之间的对应关系，以指示根据切片选取传输待传输的数据包的目标路径。

在一示例中，指示信息指示配置的路径选择规则为路径选择规则1，且业务质量要求为时延和速率。在一示例中，指示信息指示配置的路径选择规则为路径选择规则1，且业务质量要求为时延和可靠性。

可选地，所述专用信令包括以下消息之一：无线资源控制(Radio Resource Control，RRC)层信令、媒体接入控制(Media Access Control，MAC)层信令或物理层控制信令。
本发明实施例中，所述路径的传输方式包括：基于连接的传输方式；或基于无连接的传输方式。
对于传输方式为基于连接的传输方式的路径，也可称为基于连接的路径。基于连接的路径是指在进行通信时，源节点和目标节点之间需要建立对应该路径的连接，为该路径分配资源。当建立连接之后，源节点采用为该路径分配的资源进行数据传输。
对于传输方式为基于无连接的传输方式的路径，也可称为基于无连接的路径。基于无连接的路径是指在进行通信时，源节点和目标节点之间无需建立连接即可通信，例如，采用随机发送的方式。
本发明实施例中，在业务参数和路径的对应关系中，还可包括路径对应的传输方式。同一路径的传输方式不同的情况下，对应的业务质量要求可不同。
在一示例中，以业务质量要求为时延为例，时延1对应的路径为路径1，且路径1的传输方式为基于连接的传输方式，时延2对应的路径为路径1，且路径1的传输方式为基于无连接传输方式，且时延1大于时延2。

这里，本发明实施例提供的通信方法，如图8所示，包括：
S603，目标节点基于目标路径接收源节点发送的数据包。
所述目标路径是所述源节点根据所述数据包的目标业务参数所确定的，所述目标业务参数包括以下信息至少之一：所述数据包的业务质量要求、所述数据包对应的切片。
本发明实施例中，目标节点在接收到源节点基于目标路径发送的数据包之后，所述目标节点评估所述目标路径传输所述数据包的传输反馈；所述目标节点将所述目标路径传输所述数据包的传输反馈发送至所述源节点。
这里，在目标节点向源节点发送目标路径传输所述数据包的传输反馈的情况下，如图9所示，所述方法还包括：
S901，所述源节点接收所述目标节点发送的所述目标路径传输所述数据包的传输反馈。
可选地，所述目标路径传输所述数据包的传输反馈包括：所述目标路径传输所述数据包的传输结果。
可选地，当所述目标路径的传输方式为基于无连接的传输方式，所述目标路径传输所述数据包的传输反馈，包括：所述目标路径传输所述数据包的业务质量要求。
以传输反馈包括传输结果为例，在目标路径包括一条或多条路径的情况下，目标路径统计目标路径中各路径对应的表征数据包是否传输成功的传输结果，并将各路径的传输结果反馈至源节点。
在一示例中，目标路径包括：路径1和路径2，则传输结果可传输结果指示信息：I1I2，其中，I1为对应路径1的传输结果，I2为对应路径2的传输结果，在I1I2为10为情况下，表征路径1传输成功且路径2传输失败。
本发明实施例中，对传输反馈的指示方式不进行任何限定。
以传输反馈包括业务质量要求为例，目标节点评估目标路径的业务质量要求，并将评估的业务质量要求反馈至源节点，使得源节点基于接收的业务质量要求对业务质量要求和路径的对应关系中该目标路径对应的业务质量要求进行更新。
本发明实施例中，当所述路径的传输方式为基于无连接的传输方式，且所述业务参数为业务质量要求，如图10所示，包括：
S1001，所述源节点对所述目标路径对应的业务质量要求进行更新。
本发明实施例中，在S1001之前，所述目标节点评估所述目标路径的业务质量要求；所述目标节点将所评估的业务质量要求发送至所述源节点。
源节点接收到目标节点发送的评估的业务质量要求后，基于接收的评估的业务质量要求对目标路径对应的业务质量要求进行更新。
基于评估业务质量要求所使用的数据不同，目标节点评估传输方式为基于无连接的传输方式的路径的业务质量要求的评估方式包括：
评估方式A1、评估所述目标路径最近一次传输数据包的业务质量要求。
评估方式A2、基于目标路径接收所述源节点发送的心跳包，并评估所述目标路径传输所述心跳包的业务质量要求。
在评估方式为评估方式A1的情况，源节点将接收的所述目标节点发送的所述目标路径最近一次传输数据包的业务质量要求作为所述目标路径对应的业务质量要求。
当源节点上一次基于无连接的目标路径向目标节点发送数据包，目标节点根据数据包的接收情况评估该目标路径的传输方式为基于无连接的传输方式的情况下的业务质量要求，并将评估的业务质量要求反馈给源节点，源节点基于目标节点反馈的业务质量要求对路径关系中该目标路径的传输方式为基于无连接的传输方式的情况下对应的业务质量要求进行更新，更新为从目标节点接收到的业务质量要求。
在一示例中，待传输的数据包为数据包1，最近一次即上一次传输的数据包为数据包2，源节点基于传输方式为基于无连接的传输方式的路径X向目标节点发送数据包2后，目标节点基于接收的数据包2评估路径X的传输方式为基于无连接的传输方式时的业务质量要求，并将评估的业务质量要求发送至源节点，源节点对路径X 的传输方式为基于无连接的传输方式的情况下的业务质量要求进行更新。
在评估方式为评估方式A2的情况下，源节点对所述路径对应的业务质量要求进行更新，包括：源节点基于所述目标路径向所述目标节点发送心跳包；将所述目标节点发送的所述路径传输所述心跳包的业务质量要求作为所述目标路径对应的业务质量要求。
源节点周期性的基于传输方式为基于无连接的传输方式的目标路径向目标节点发送心跳包，目标节点基于传输方式为基于无连接的传输方式的目标路径接收的心跳包，并评估目标路径的传输方式为基于无连接的传输方式时的业务质量要求，将所评估的业务质量要求反馈给源节点，源节点对基于无连接的目标路径的业务质量要求进行更新，更新为从目标节点接收到的业务质量要求
本发明实施例中，源节点周期性的基于包括目标路径的所有或部分可能的基于无连接的路径向目标节点发送心跳包，目标节点基于各基于无连接的路径接收的心跳包评估各基于无连接的路径的业务质量要求，并将各基于无连接的路径的业务质量要求反馈给源节点，源节点对各基于无连接的路径的业务质量要求进行更新，更新为从目标节点接收到的相应路径的业务质量要求。
在本发明实施例中，基于评估业务质量要求所基于的转发节点不同，目标节点评估目标路径的业务质量要求，包括：
评估方式B1、获所述目标路径中每一转发节点的业务质量要求，并基于每一转发节点的业务质量要求得到所述所述目标路径的业务质量要求；
评估方式B2、获取所述目标路径中业务质量要求最差的转发节点的业务质量要求。
在评估方式B1中，目的节点获取的是目标路径中每一跳的业务质量要求，并对每一跳的业务质量要求汇总后获得整个目标路径的业务质量要求。
在一示例中，目标路径中包括2个转发节点：转发节点1和转发节点2，则分别获取转发节点1的时延和转发节点2的时延，并基于转发节点1的时延和转发节点2的时延得到该目标路径的时延。
在评估方式B2中，目的节点将源节点到目的节点之间的最差一跳的业务质量要求作为该目标路径的业务质量要求。
在一示例中，目标路径中包括2个转发节点：转发节点1和转发节点2，则分别获取转发节点1的速率和转发节点2的速率，并将两个速率中较小的速率作为该目标路径的速率。
本发明实施例中，所述评估的业务质量要求的指示方式包括：业务质量要求；或业务质量要求对应的等级信息。
以业务质量要求的指示方式为业务质量要求为例，目标节点向源节点发送所评估的业务质量要求本身。例如，评估的时延为10微秒(μs)，则指示信息为时延10μs。
以业务质量要求的指示方式为业务质量要求对应的等级为例，目标节点向源节点发送所评估的业务质量要求对应的等级。例如，评估的时延为10μs，且10μs的时延对应的时延为一级，则指示信息为表征时延为一级的指示信息。
本发明实施例中，源节点根据待传输的数据包的目标业务参数，确定目标路径；所述目标业务参数包括以下信息至少之一：所述数据包的业务质量要求、所述数据包对应的切片；所述源节点基于所述目标路径将所述数据包发送至目标节点；从而基于数据包的业务质量要求或数据包对应的切片在网络中选择传输数据包的路径，使得传输数据包的路径能够贴合当前数据包的业务需求，在保证数据包的传输的情况下，减少资源的浪费。
下面，通过不同的实例对本发明实施例提供的通信方法进行举例说明。
在未来无线网络中，源节点与目的节点之间可以通过Uu/SL直接单跳连接，也可以通过多跳方式进行连接，从而保证数据传输。而按照数据量的大小，源节点与目的节点之间可以通过基于无连接的方式进行数据传输，也可以通过基于连接的方式进行传输。其中，基于无连接的方式是指在进行通信时，源节点和目标节点之间无需建立连接即可通信，例如，可以采用随机发送的方式；基于连接的方式是指在进行通信时，源节点和目标节点之间需要建立连接，其基于建立的连接进行通信，并采用分配给所建立的连接的资源进行数据传输，而不会发生任何资源碰撞。
实例一、源节点基于路径选择规则选取进行数据传输的路径。
源节点(例如终端或者基站)在进行数据传输中，可能采用单一的转发节点即单跳直接将数据传输到目的节点；也可能通过多个转发节点即多跳的方式将数据传输到目的节点。如图11所示，源节点和目标节点之间进行数据传输的路径包括：路径1、路径2、路径3和路径4这四条路径，其中，路径1包括一个接入节点：移动终端，路径2包括一个接入点：汽车，路径3包括一个接入点：基站，路径4包括两个接入点：卫星1和卫星2，路径1、路径2和路径3为基于单跳的路径，路径4为基于多跳的路径。
源节点可基于路径选择规则选取进行数据传输的路径，路径选择规则可包括：
路径选择规则1：基于业务质量要求选择路径。
路径选择规则2：基于切片选择路径。
基于路径选择规则1，源节点可以按照待传的数据包的时延、速率、可靠性等业务质量要求中的一个或多个选择路径。例如，如果待传数据包要求的时延较短，源节点可以采用时延较短的路径即时延较短的一条或者多条路径进行数据包的传输；例如，如果待传数据包要求一定速率，源节点可以采用满足速率要求的路径即满足速率要求的一条或多条路径进行数据包的传输，当采用多条路径，多条路径共同满足一定速率的数据包的传输；例如，如果待传数据包要求一定可靠性，源节点可以采用满足可靠性要求的路径即满足可靠性要求的一条或者多条路径进行数据包的传输。
在实际应用中，业务质量要求还可以包括时延、速率、可靠性以外的其他内容。选择路径的业务质量要求可以是上述一种或者多种业务质量要求的合并。
不同业务质量要求可以通过数据无线承载体现，也可以通过业务数据流体现。其中，无线数据承载是指无线侧分配的对应不同业务的数据承载；而业务数据流也是无线侧对应不同业务的承载方式。业务质量要求可通过DRB ID或者Flow ID确定。
基于路径选择规则2，源节点根据待传数据包所属业务的切片选择路径。例如，如果传输的数据包属于游戏业务，游戏业务的切片x对应的路径为路径X，则源节点通过路径X进行数据传输，路径X可以包括一条路径也可以包括多条路径，路径X可以包括基于连接的路径，可以包括基于无连接的路径；例如，如果待传输的数据包属于小包业务，对应小包业务(例如微信、QQ信息)的切片为切片y，对应切片y的路径为路径Y，路径Y包括一条或多条基于无连接的路径，源节点可以直接通过一个或多个基于无连接的路径进行数据传输，从而避免信令浪费；例如，如果传输的数据包属于需要稳定传输的大包业务(例如视频流)，对应大包业务的切片为切片z，切片z对应的路径为路径Z，且路径Z包括基于连接的路径，源节点可以通过稳定链路建立连接，从而保证业务传输质量。
路径选择规则由网络通过指示信息配置给源节点，所述指示信息可以是系统信息也可以是专用信令，包括专用RRC信令、MAC信令或者物理层控制信令。
当数据包通过一条或者多条路径到达目的节点时，目的节点可以通过信令反馈各个 路径的传输结果。例如数据包通过A、B、C、D这4条路径进行传输，则通过对应4条路径的4个比特进行分别指示各路径的传输结果指示。例如，当比特指示为1010时，表示路径A和C传输成功，B和D传输失败。其中，目标节点反馈传输结果的信令可为确认信令等专用信令或者寻呼等广播信令。
实例二、目标节点向源节点反馈基于无连接的路径的业务质量要求的评估信息。
如实例一中所述，源节点按照路径选择规则选择不同路径进行数据传输，为了适用路径选择规则，尤其是规则1的基于业务质量要求选择不同路径，且路径是无连接的路径时，需要对路径的情况有所评估，包括路径的时延、吞吐量、可靠性等方面的业务质量要求。
这里，可由目标节点评估基于无连接的路径的业务质量要求，并将评估的业务质量要求发送至源节点，源节点将接收的业务质量要求更新为该路径对应的业务质量要求。
评估的业务质量要求的获取方式包括：
方式1、将源节点上次通过基于无连接的路径进行数据发送的情况作为参考。
在一示例中，源节点在上次向目的节点发送数据包时，目的节点侧按照接收数据包的情况给出相应业务质量要求的评估结果，并且将所评估的业务质量要求反馈给源节点。所述评估的方面包括：时延、获得的速率/链路质量、重传次数等业务质量要求。
上述业务(时延、获得的速率/链路质量、重传次数)作为数据包的控制部分由目的节点从转发数据包的转发节点获取，或者作为单独的控制包由目的节点从转发数据包的转发节点获取。在目的节点评估时，可以考虑评估从源节点到目的节点的总路径，也可以考虑评估从源节点到目的节点的最差一跳即业务质量要求最差的转发节点。
方式2、采用心跳包进行无连接路径的路径维护，即源节点在可能进行数据传输的基于无连接的路径上定时周期性发送心跳包值目的节点，目的节点通过接收心跳包的情况评估基于无连接的路径的包括时延、链路质量、重传次数等业务质量要求。目的节点将评估结果反馈给源节点，帮助源节点进行基于无连接的路径的选取。
以上评估结果可以由目的节点通过特定信令反馈给源节点。反馈的评估结果具体的信息，包括时延、链路质量、重传次数，也可以是粗颗粒度的等级信息，例如好、中、差。
