Description

确定信息的传输路径的方法和节点
本申请要求于2015年1月14日提交中国专利局、申请号为201510017300.5、发明名称为“确定信息的传输路径的方法和节点”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明实施例涉及通信领域，并且更具体地，涉及确定信息的传输路径的方法和节点。
背景技术
片上互联网络(network-on-chip，简称为“NoC”)成为当前众核系统的发展趋势。网格Mesh结构和平面的硅片几何结构可以很好的匹配，并且提供比一维的总线或者是单环结构更好的可测量性和更高的带宽。目前NoC系统一般采用2D-mesh结构，比如Teraflop80核和Tilera64核。
当节点的数量增多，有些节点在芯片的生产过程中可能会坏死，而且在实际使用中有些节点会成为热点，寿命也会小于其他节点。当前提出针对NoC上节点分区域(partition或者region)的概念，即把其中的一部分节点组成一个小区域系统独立完成某一任务，此时临近节点需要经过分区域进行通信时，是不被允许的。
针对上述问题，相关技术根据待传输的信息的类型设定信息的传输路径。位于故障环(fault ring)和故障链(fault chain)上的节点需要记录其参考(reference)节点的坐标信息。当传输信息遇到故障环和故障链时，根据故障环和故障链的类型(是否为s-chain)、参考节点的坐标信息以及信息的类型设定沿故障环和故障链顺时针或者是逆时针进行信息传输。在通信过程中节点通过该方法确定信息的传输路径时，会造成链路资源的浪费，降低通 信的实时有效性。

具体实施方式
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描述。
应理解，本发明实施例的技术方案可以应用于基于网格mesh结构的网络通信系统，例如可以是片上互联网络(Network-on-Chip，简称为“NoC”)，也可以应用于其他基于网格结构的网络，但为描述方便，本发明实施例将以NoC为例进行说明，但本发明并不限于此。
图1是根据本发明实施例的片上互联网络的架构实例的示意图。如图1所示，片上互联网络中可以包括几种不同的节点，分别为正常(active)节点、非正常(deactivated)节点、不安全(unsafe)节点和故障(faulty)节点。其中，非正常节点是指连接到两个或多个故障节点或非正常节点的正常节点；不安全节点是指连接到至少一个正常节点的非正常节点。相连接的非正常节点和故障节点组成的矩形区域称为故障区域(faulty region)，包围环绕该故障区域的正常节点组成故障环(faulty ring)。
图2示出了根据本发明实施例的确定信息的传输路径的方法的示意性流程图。如图2所示，该方法100包括：
S110，根据当前节点与故障环的位置关系确定该当前节点的类型；
S120，根据该类型，确定传输该信息的下一跳节点；
S130，将该信息传输给该下一跳节点。
具体而言，在信息传输的过程中，当信息传递到一个节点时，该节点即成为当前节点，该当前节点根据自身与故障环的位置关系确定该当前节点的类型；根据该类型，确定传输该信息的下一跳节点；并将该信息传输给该下一跳节点。
因此，本发明实施例的确定信息的传输路径的方法，节点根据当前节点与故障环的位置关系确定该当前节点的类型；根据该类型，确定传输该信息的下一跳节点；将该信息传输给该下一跳节点。由此，在通信过程中能够确定出优化的容错传输路径，从而能够节省链路资源，确保通信的实时有效性。
应理解，在本发明实施例中，当前节点与故障环的位置关系是指当前节点是否位于故障环上。下一跳节点是指直接接收当前节点传输的信息的节点，当前节点的上一跳节点指直接向该当前节点传输信息的节点。
还应理解，在本发明实施例中，可以采用现有技术中已有的生成算法生成故障环。其中，每个节点都有自我检测功能，并能将自身的状态信息发送给相连接的相邻节点，由此可以生成形状为矩形的故障环。例如可以根据程 序(1)和表1生成故障环，但本发明并不限于此。本发明实施例中生成故障环的方法的程序(1)为：
Procedure Form-Ring/*current node is X*/
if(E_X or W_X is faulty,unsafe,or deactivated)
Send status information to S_X and N_X)；

Send status information to E_X and W_X)；
Receive from all active neighbors their status information；
Determine whether X is corner nodes of fault rings according to Table 1；
表1
Figure PCTCN2016070824-appb-000001
可选地，在S110中，在该当前节点不在故障环上时，确定该当前节点的类型为第一类型；或，在该当前节点在故障环上时，根据该当前节点的上一跳节点与故障环的位置关系确定该当前节点的类型。
具体而言，在该当前节点在故障环上且该当前节点的上一跳节点不在故障环上时，确定该当前节点的类型为第二类型；或，在该当前节点在故障环上且该当前节点的上一跳节点在与该当前节点所在的故障环不相同的故障环上时，确定该当前节点的类型为第二类型；或，在该当前节点在故障环上且该当前节点的上一跳节点在该当前节点所在的故障环上时，确定该当前节点的类型为第三类型。
可选地，在S120中，在该当前节点的类型为第一类型时，确定预设传输规则；根据该预设传输规则，确定该下一跳节点。例如，可以预先设定正常节点上的路由传输规则为XY路由，当信息传输到当前节点时，当前节点判断自身的水平坐标与目的节点的水平坐标之间的关系，如果两者不相等，则当前节点沿着水平方向继续传输信息，下一跳节点即为沿原水平方向的下一个节点，若两者水平方向相同，则下一跳节点即为沿竖直方向并且在该当前节点和目的节点之间的下一个节点。但本发明并不限于此。
可选地，在S120中，在该当前节点的类型为第一类型时，当前节点也可以根据目的节点相对于当前节点的相对位置，确定下一跳节点，还可以根据其他的方式确定下一跳节点，本发明对此不作限定。
可选地，在S120中，在该当前节点的类型为第三类型时，当前节点根据该当前节点的位置信息、目的节点的位置信息和该当前节点的上一跳节点的位置信息，确定该下一跳节点。
具体而言，当信息传输到第三类型的节点时，该节点通过比较自身的坐标与目的节点的坐标，确定两者是否存在相等的水平坐标或竖直坐标，如果两者的水平坐标相等，则下一跳节点即为与当前坐标在同一竖直方向上且在该节点和目的节点之间的下一个节点，如果两者的竖直坐标相等，则下一跳节点即为与该节点在同一水平方向上且在该节点和目的节点之间的下一个节点。如果两者的水平坐标和竖直方向均不相等，则下一跳节点即为沿着该节点的上一跳节点与该节点确定的方向(顺时针或逆时针)上的下一个节点。
可选地，如图3所示，在根据本发明实施例的确定信息的传输路径的方法100中的S120可以如下所述。
S121，在该当前节点的类型为第二类型时，确定目的节点相对于该当前节点的相对位置；
S122，根据该相对位置，确定该下一跳节点。
可选地，在S121中，节点可以根据相对位置关系表确定目的节点相对于当前节点的相对位置，该相对位置关系表可以是预先生成并存储在节点内部的表格。节点还可以根据当前节点的坐标信息和目的节点的坐标信息，通过计算确定出目的节点相对于当前节点的相对位置，但本发明并不限于此。
可选地，在S122中，当前节点可以根据相对位置与路由规则的对应关系表确定传输信息的下一跳节点，该相对位置与路由规则的对应关系表可以是预先生成并存储在节点内部的表格，但本发明并不限于此。
可选地，在S122中，当前节点可以确定其所在的故障环的类型，根据该故障环的类型和目的节点相对于当前节点的相对位置确定下一跳节点。可选地，可以预先设置当前节点所在的故障环的类型、目的节点相对于当前节点的相对位置和路由规则之间的关系表，并存储在节点中，当前节点根据该关系表即可确定下一跳节点，但本发明并不限于此。
在本发明实施例中，可选地，节点可以根据故障环包括的所有节点的坐标信息，确定该故障环的类型。优选地，节点可以通过确定故障环上的至少两个节点的坐标信息，确定该故障环的类型，其中，该至少两个节点中的第一节点和第二节点的连线为该故障环的对角线。例如，可以根据该故障环的东北角节点的坐标信息和西南角节点的坐标信息，确定该故障环的类型；或，根据该故障环的西北角节点的坐标信息和东南角节点的坐标信息，确定该故障环的类型。
在本发明实施例中，可选的，可以将网络中任意节点所在的位置确定为坐标原点，与该任意节点相关联的东、西、南、北四个方向中任意两个不在 同一水平线上的两个方向作为水平方向X和竖直方向Y。优选的，可以将该网络中的西南角节点、东北角节点、西北角节点和东南角节点中的任一节点所在的位置确定为坐标原点，与该节点相关联的两个边界分别作为水平方向和竖直方向。例如，可以将该网络的西南角节点的位置确定为坐标原点；将该网络的南边界确定为水平方向X，水平向右为X的正方向；将该网络的西边界确定为竖直方向Y，竖直向上为Y的正方向。则此时可以根据故障环的东北角节点的坐标(x1,y1)和故障环的西南角节点的坐标(x2,y2)，确定该故障环的类型。但本发明并不限于此。
具体而言，假设一个片上互联网络包括M×N个节点，其中，网络的水平方向有M个节点，竖直方向有N个节点，如图4所示，若0≤x1≤(M-1)，0≤y1≤(N-1)，0≤x2≤(M-1)，0≤y2≤(N-1)，则该故障环为正常环；若x1＝M，0≤y1≤(N-1)，0≤x2≤(M-1)，0≤y2≤(N-1)，则该故障环为东环；若x1＝M，y1＝N，0≤x2≤(M-1)，0≤y2≤(N-1)，则该故障环为东北环；若0≤x1≤(M-1)，y1＝N，0≤x2≤(M-1)，0≤y2≤(N-1)，则该故障环为北环；若0≤x1≤(M-1)，y1＝N，x2＝-1，0≤y2≤(N-1)，则该故障环为西北环；若0≤x1≤(M-1)，0≤y1≤(N-1)，x2＝-1，0≤y2≤(N-1)，则该故障环为西环；若0≤x1≤(M-1)，0≤y1≤(N-1)，x2＝-1，y2＝-1，则该故障环为西南环；若0≤x1≤(M-1)，0≤y1≤(N-1)，0≤x2≤(M-1)，y2＝-1，则该故障环为南环；若x1＝M，0≤y1≤(N-1)，0≤x2≤(M-1)，y2＝-1，则该故障环为东南环。
也就是说，正常环的四条边界均位于网络的内部；东环的东边界为网络的东边界，其他边界均位于网络的内部；东北环的东边界为网络的东边界且北边界为网络的北边界，其他边界均位于网络的内部；北环的北边界为网络的北边界，其他边界均位于网络的内部；西北环的北边界为网络的北边界且西边界为网络的西边界，其他边界均位于网络的内部；西环的西边界为网络的西边界，其他边界均位于网络内部，西南环的西边界为网络的西边界且南 边界为网络的南边界，其他边界均位于网络的内部；南环的南边界为网络的南边界，其他边界均位于网络的内部，东南环的南边界为网络的南边界且东边界为网络的东边界，其他边界均位于网络的内部。
优选地，在S122中，当前节点根据该当前节点的坐标信息、该目的节点的坐标信息和该当前节点所在的故障环上的第一节点的坐标信息和第二节点的坐标信息，确定该下一跳节点，其中，该第一节点和该第二节点的连线为该当前节点所在的故障环的对角线。例如该第一节点可以为故障环的东北角节点，相应地，该第二节点可以为故障环的西南角节点；该第一节点还可以为故障环的西北角节点，相应地，该第二节点还可以为故障环的东南角节点。
具体而言，假设当前节点位于故障环的南边界上，目的节点位于当前节点的北方或东北方或西北方，此时可以通过判断当前节点到该故障环的东北角节点及该东北角节点到该目的节点在水平方向上需要经过的总路径的长度和当前节点到该故障环的西南角节点及该西南角节点该到目的节点在水平方向上需要经过的总路径的长度，确定下一跳节点是在当前节点的逆时针方向还是顺时针方向。若前者大于后者，则下一跳节点为在该当前节点的顺时针方向上的第一个节点，否则，该下一跳节点为在该当前节点的逆时针方向上的第一个节点。
优选地，在本发明实施例中，在当前节点的类型为第一类型时，当前节点可以根据下列伪代码确定信息的传输路径，但本发明并不限于此。本发明实施例的确定传输信息的路径的方法的伪代码为：

图5(a)和图5(b)分别示出了根据现有技术中确定信息的传输路径的方法和根据本发明实施例的确定信息的传输路径的方法确定的传输路径的示意图。
如图5(a)和5(b)所示，S1(9,1)、D1(7,8)、S2(5,9)、D2(9,4)分别代表第一源节点、第一目的节点、第二源节点和第二目的节点。下面将以图5(b)中信息从S1传输到D1为例，描述本发明实施例的确定信息的传输路径的方法。
设定正常节点的路由传输方法为XY路由，节点S1(9,1)的类型为第一类型，因此信息首先沿X轴正常传输，之后遇到故障环上的节点(8,1)，该节点(8,1)的类型为第二类型，并且目的节点在该当前节点(8,1)的西北方，所以信息只能沿该故障环逆时针传输，信息传到坐标为(8,2)的节点，该节点(8,2)的类型为第三类型，并且坐标为(8,2)的节点的水平坐标和竖直坐标均与目的节点不相同，所以继续沿逆时针方向沿该故障环传输信息，传输到坐标为(7,2)的节点，该节点的水平坐标与目的节点相同，所以信息开始沿Y方向继续传输，传到坐标为(7,3)的节点，该节点(7,3)是故障环上的节点，并且目的节点在该节点(7,3)的北方，因此需要根据当前节点的坐标、目的节点的坐标、东北角节点的坐标和西南角节点的坐标确定东西边界距离当前节点和目的节点的距离哪个更小，经过判断故障环的东边界距离当前节点和目的节点的距离更小，所以信息在该故障环上需沿逆时针传输，因此信息传输到节点(8,3)，此时当前节点的水平坐标和竖直坐标均与目的节点不相同，所以继续沿逆时针方向沿该故障环传输信息，传输到节点(8,4)，基于相同的确定下一跳节点的方法，信息传输至节点(7,7)，此时当前节点和目的节点水平方向坐标相同，所以信息沿Y方向进行传输到目的节点D1(7,8)。
通过对比图5(a)和图5(b)可以看出，当节点间有多次跨故障环通信时，采用本发明实施例的方法确定信息的传输路径，可以节省链路资源，确保通信的实时有效性。
因此，本发明实施例的确定信息的传输路径的方法，节点根据当前节点与故障环的位置关系确定该当前节点的类型；根据该类型，确定传输该信息的下一跳节点；将该信息传输给该下一跳节点。由此，在通信过程中能够确定出优化的容错传输路径，从而能够节省链路资源，确保通信的实时有效性。

具体而言，在信息传输的过程中，当信息传递到一个节点时，该节点即成为当前节点，该当前节点根据自身与故障环的位置关系确定该当前节点的类型；根据该类型，确定传输该信息的下一跳节点；并将该信息传输给该下一跳节点。
因此，本发明实施例的节点，根据当前节点与故障环的位置关系确定该当前节点的类型；根据该类型，确定传输该信息的下一跳节点；将该信息传输给该下一跳节点。由此，在通信过程中能够确定出优化的容错传输路径，从而能够节省链路资源，确保通信的实时有效性。
在本发明实施例中，可选地，该确定模块11具体用于：在该当前节点不在故障环上时，确定该当前节点的类型为第一类型；或，在该当前节点在故障环上时，根据该当前节点的上一跳节点与故障环的位置关系确定该当前节点的类型。

在本发明实施例中，可选地，该确定模块11还具体用于：在该当前节点的类型为第二类型时，确定目的节点相对于该当前节点的相对位置；根据该相对位置，确定该下一跳节点。
在本发明实施例中，可选地，该确定模块11还具体用于：根据该当前节点的坐标信息、该目的节点的坐标信息和该当前节点所在的故障环上的第一节点的坐标信息和第二节点的坐标信息，确定该下一跳节点，其中，该第一节点和该第二节点的连线为该当前节点所在的故障环的对角线。
在本发明实施例中，可选地，该确定模块11还具体用于：在该当前节点的类型为第三类型时，根据该当前节点的位置信息、目的节点的位置信息和该当前节点的上一跳节点的位置信息，确定该下一跳节点。

因此，本发明实施例的节点，根据当前节点与故障环的位置关系确定该当前节点的类型；根据该类型，确定传输该信息的下一跳节点；将该信息传输给该下一跳节点。由此，在通信过程中能够确定出优化的容错传输路径，从而能够节省链路资源，确保通信的实时有效性。
图7示出了根据本发明另一实施例的节点20。如图7所示，该节点20包括处理器21、存储器22、总线系统23和发送器24。其中，处理器21、存储器22、发送器24通过总线系统23相连，该存储器22用于存储指令，该处理器21用于执行该存储器22存储的指令，以控制发送器24发送信号；其中，该处理器21用于根据当前节点与故障环的位置关系确定该当前节点的类型；该处理器21还用于根据该类型，确定传输该信息的下一跳节点；该发送器24用于将该信息传输给该处理器21确定的该下一跳节点。
因此，本发明实施例的节点，根据当前节点与故障环的位置关系确定该当前节点的类型；根据该类型，确定传输该信息的下一跳节点；将该信息传 输给该下一跳节点。由此，在通信过程中能够确定出优化的容错传输路径，从而能够节省链路资源，确保通信的实时有效性。
应理解，在本发明实施例中，该处理器21可以是中央处理单元(Central Processing Unit，简称为“CPU”)，该处理器21还可以是其他通用处理器、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、分立硬件组件等。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。
