Description

传输网络信息的方法及装置技术领域 Method and device for transmitting network information

本发明涉及云计算技术领域，尤其涉及一种传输网络信息的方法及装置。 The present invention relates to the field of cloud computing technologies, and in particular, to a method and device for transmitting network information.

背景技术 Background technique

随着电子信息技术的发展，许多物理网络都需要生成虚拟机来构建虚拟网络，以满足各种各样业务的需求。 With the development of electronic information technology, many physical networks need to generate virtual machines to build virtual networks to meet the needs of various businesses.

现有技术中，常用的虚拟网络技术有虚拟扩展局域网（ Virtual extensible Local Area Network, 筒称 VXLAN ) , 即在现有的物理三层网络上构建跨越多个服务器的虚拟化二层网络。在实际应用中， VXLAN需要通过占用物理交换机的密集模式协议无关组播（PIM Dense Mode, 筒称 PIM-DM ) 来进行虚拟机的介质访问控制（Media Access Control , 筒称 MAC ) 地址学习和隧道端点网络之间互连的协议（ Internet Protocol , 筒称 IP ) 地址的学习。 In the prior art, a commonly used virtual network technology is a virtual extensible local area network (VXLAN), that is, a virtualized layer 2 network spanning multiple servers on an existing physical layer 3 network. In practical applications, VXLAN needs to use the dense mode protocol-independent multicast (PIM-DM) of the physical switch to perform media access control (Media Access Control, MAC address) address learning and tunneling of the virtual machine. The learning of the protocol (Internet Protocol, IP address) of the interconnection between the endpoint networks.

目前，物理交换机所容纳的 PIM-DM都比较少，普遍在 500-2000个组左右。而在物理交换机上运行的虚拟网络的规模越大，需要占用的 PIM-DM越多，并且在同一个物理交换机上可能同时运行多个虚拟网络，从而在实际应用中常常造成物理交换机中的 PIM-DM 不够用，使得物理交换机难以支持更大规模虚拟网络。而若要增加 PIM-DM 以使物理交换机能够支持更大规模虚拟网络，则需要增加很多成本来给物理交换机增设额外的运算设备和存储设备，或是使用具有更多 PIM-DM 的大容量物理交换机，但是这类大容量物理交换机的价格普遍较高，从而使得现有技术中构建大规模虚拟网络的成本较高，限制了虚拟网络技术的应用。 At present, physical switches accommodate relatively few PIM-DMs, generally around 500-2000 groups. The larger the size of the virtual network running on the physical switch, the more PIM-DMs need to be occupied, and the multiple virtual networks may be running on the same physical switch. In practice, the PIM in the physical switch is often caused. -DM is not enough, making it difficult for physical switches to support larger virtual networks. If you want to increase PIM-DM to enable physical switches to support larger virtual networks, you will need to add a lot of cost to add additional computing devices and storage devices to physical switches, or use large-capacity physics with more PIM-DMs. Switches, but the price of such large-capacity physical switches is generally higher, which makes the cost of building large-scale virtual networks in the prior art higher, which limits the application of virtual network technologies.

具体实施方式 detailed description

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，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。 The technical solutions in the embodiments of the present invention are clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

本发明实施例提供一种传输网络信息的方法，如图 1所示，包括以下步骤： An embodiment of the present invention provides a method for transmitting network information. As shown in FIG. 1, the method includes the following steps:

101 , 信息服务器获取虚拟网络中的虚拟机的地址信息。需要说明的是，本实施例所述的方法可以由信息服务器执行，信息服务器为一种具备计算和存储功能的、用于记录虚拟机的地址信息的设备，例如：服务器、移动工作站、终端设备等。进一步的，信息服务器可以是一个专门的硬件设备，例如：在物理层面上，服务器 1和服务器 2分别用于承载虚拟机的运行，而作为信息服务器的服务器 3则用于在服务器 1和服务器 2上的虚拟机进行数据交互时，执行本实施例所述的方法；可选的，信息服务器也可以由一个硬件设备所划分出的部分运算 /存储资源构成，例如：在物理层面上，服务器 1和服务器 2分别用于承载虚拟机的运行，同时服务器 1还分出了一部分的运算 /存储资源来承担本实施例中信息服务器员可以通过时分复用等技术手段实现一个服务器同时承载虚拟机的运行并执行本实施例所述的方法。 101. The information server obtains address information of the virtual machine in the virtual network. It should be noted that the method in this embodiment may be performed by an information server, which is a device for recording address information of a virtual machine, such as a server, a mobile workstation, or a terminal device, having a computing and storage function. Wait. Further, the information server may be a dedicated hardware device, for example: On the physical level, the server 1 and the server 2 are respectively used to carry the operation of the virtual machine, and the server 3 as the information server is used in the server 1 and the server 2 When the virtual machine performs data interaction, the method described in this embodiment is performed. Optionally, the information server may also be composed of a part of computing/storage resources divided by a hardware device, for example: at a physical level, the server 1 And the server 2 is used to carry the operation of the virtual machine, and the server 1 also allocates a part of the operation/storage resources to bear the information server in the embodiment. The server can implement the virtual machine by using a technical means such as time division multiplexing. The method described in this embodiment is run and executed.

进一步的，所述地址信息包括：所述虚拟机的 IP地址和 MAC地址、所述虚拟机所在的物理设备的 IP地址和 MAC地址和所述虚拟机所在的虚拟网络的虚拟网络标识（ Virtual Network Identifier , 筒称 VNI ) 号。在本发明实施例的实际应用中，虚拟机发出的数据包包括了用于表示该虚拟机的 IP地址和 MAC地址，当该虚拟机发出的数据到达了该虚拟机所在的物理设备后，可以由物理设备对该虚拟机发出的数据进行重新封装，并添加该虚拟机所在的物理设备的 IP地址和 MAC地址以及该虚拟机所在的虚拟网络的 VNI号。 Further, the address information includes: an IP address and a MAC address of the virtual machine, an IP address and a MAC address of a physical device where the virtual machine is located, and a virtual network identifier of a virtual network where the virtual machine is located (Virtual Network Identifier, the cylinder is called VNI). In the practical application of the embodiment of the present invention, the data packet sent by the virtual machine includes an IP address and a MAC address for indicating the virtual machine. After the data sent by the virtual machine reaches the physical device where the virtual machine is located, The data sent by the virtual machine is re-encapsulated by the physical device, and the IP address and MAC address of the physical device where the virtual machine is located and the VNI number of the virtual network where the virtual machine is located are added.

在本实施例中，信息服务器可以在虚拟网络中的虚拟机启动时，通过获取的所述虚拟机的 IP地址和 MAC地址、所述物理设备的 IP地址和 MAC 具体的，信息服务器可以通过现有的技术手段获取并储存虚拟网络中的各个虚拟机的 IP地址和 MAC地址、虚拟机所在的诸如服务器等物理设备的 IP地址和 MAC地址，以及虚拟机所在的虚拟网络的 VNI号等地址信息。其中，信息服务器获取地址信息的具体方式可以有多种，例如：虚拟机在启动时可以自动发起动态主机配置协议 ( Dynamic Host Configuration Protocol, 筒称 DHCP )进程，以便于虚拟机所在的物理服务器通过执行该进程，可以截获由 DHCP服务器发送至所述虚拟机的用于给所述虚拟机分配 IP地址和 MAC地址的 DHCP消息，并从中获取所述虚拟机的 IP地址和 MAC地址；然后，所述物理服务器再将自身的 IP地址和 MAC地址，以及所述虚拟机所在的虚拟网络的 V N I号等信息，同所述虚拟机的 I P地址和 MAC地址一起发送至信息服务器。需要说明的是，当虚拟网络运行时，具体实现方式可以是本领域技术人员所熟知的任意方式，在此不再赘述。 In this embodiment, the information server may obtain the IP address and MAC address of the virtual machine, the IP address of the physical device, and the MAC address when the virtual machine in the virtual network is started. Some technical means acquire and store the IP address and MAC address of each virtual machine in the virtual network, the IP address and MAC address of the physical device such as the server where the virtual machine is located, and the address letter such as the VNI number of the virtual network where the virtual machine is located. Interest. The information server can obtain the address information in various ways. For example, the virtual machine can automatically initiate the dynamic host configuration protocol (DHCP) process when the virtual machine starts, so that the physical server where the virtual machine is located can pass. Executing the process, the DHCP message sent by the DHCP server to the virtual machine for allocating an IP address and a MAC address to the virtual machine may be intercepted, and an IP address and a MAC address of the virtual machine are obtained therefrom; The physical server then sends information such as its own IP address and MAC address, and the VNI number of the virtual network where the virtual machine is located, to the information server along with the IP address and MAC address of the virtual machine. It should be noted that, when the virtual network is running, the specific implementation manner may be any manner well known to those skilled in the art, and details are not described herein again.

102 , 接收第一虚拟机所在的物理设备根据所述第一虚拟机的请求生成的查询请求消息，根据所述查询请求消息获取第二虚拟机的地址信息。 102. Receive a query request message generated by the physical device where the first virtual machine is located according to the request of the first virtual machine, and obtain address information of the second virtual machine according to the query request message.

其中，所述请求消息中包括用于识别第二虚拟机的信息。例如：当第一虚拟机发出的请求消息为地址解析协议（ Address Resolution Protocol, 筒称 ARP )请求时， ARP请求中包括的用于识别第二虚拟机的信息为第二虚拟机的 IP地址。需要说明的是，第一虚拟机获取第二虚拟机的 IP地址的具体实现方式可以是本领域技术人员所熟知的任意方式，在此不再赘述。 The request message includes information for identifying the second virtual machine. For example, when the request message sent by the first virtual machine is an Address Resolution Protocol (ARP) request, the information included in the ARP request for identifying the second virtual machine is the IP address of the second virtual machine. It should be noted that the specific implementation manner in which the first virtual machine obtains the IP address of the second virtual machine may be any manner known to those skilled in the art, and details are not described herein again.

在实际应用中，作为本地虚拟机的第一虚拟机若要与目的虚拟机实现数据交互，则需要获取作为目的虚拟机的第二虚拟机的 MAC地址。同时，本地虚拟机所在的物理设备需要获取目的虚拟机所在的物理设备的 I P地址和 MAC地址。 In a practical application, if the first virtual machine that is the local virtual machine needs to perform data interaction with the destination virtual machine, the MAC address of the second virtual machine that is the destination virtual machine needs to be obtained. At the same time, the physical device where the local VM resides needs to obtain the IP address and MAC address of the physical device where the destination VM resides.

在本实施例中，信息服务器接收到第一虚拟机发出的请求消息，该请求消息表示第一虚拟机需要与第二虚拟机进行数据交互，信息服务器可以根据所述请求消息中包含的第二虚拟机的 I P地址在已获取的虚拟机的地址信息中查找该第二虚拟机对应的 MAC地址、第二虚拟机所在物理设备的 IP地址和 MAC地址等地址信息，并将查找到的第二虚拟机的 MAC地址、第二虚拟机所在物理设备的 IP地址和 MAC地址等地址信息发送至第一虚拟机，以便第一虚拟机使用所述地址信息与第二虚拟机进行数据交互。In this embodiment, the information server receives the request message sent by the first virtual machine, where the request message indicates that the first virtual machine needs to perform data interaction with the second virtual machine, and the information server may be according to the second part included in the request message. The IP address of the virtual machine searches for the address information of the MAC address corresponding to the second virtual machine, the IP address and the MAC address of the physical device where the second virtual machine is located in the address information of the obtained virtual machine, and finds the second information.

如图 2a所示，为本发明实施例提供的另一种传输网络信息的方法的流程图，包括以下步骤： As shown in FIG. 2a, another flow chart of a method for transmitting network information according to an embodiment of the present invention includes the following steps:

201 , 虚拟网络中的虚拟机启动后，信息服务器获取虚拟机的 MAC地址和 IP地址、所述虚拟机所在的物理设备的 MAC地址和 IP地址以及所述虚拟机所在的虚拟网络的 VNI号。 201. After the virtual machine in the virtual network is started, the information server obtains a MAC address and an IP address of the virtual machine, a MAC address and an IP address of a physical device where the virtual machine is located, and a VNI number of the virtual network where the virtual machine is located.

其中，虚拟机的 MAC地址和 IP地址是由虚拟机所在的物理设备通过截获 DHCP服务器发送至虚拟机的 DHCP消息获取的，所述 DHCP消息包括虚拟机的 IP地址和 MAC地址。进而，虚拟机所在的物理设备将所述虚拟机的 MAC地址和 IP地址、虚拟机所在的物理设备的 MAC地址和 IP地址以例中， DHCP消息的具体传输过程可以与现有技术中常用的 DHCP技术的具体实施过程相同。 The MAC address and the IP address of the virtual machine are obtained by intercepting the DHCP message sent by the DHCP server to the virtual machine by the physical device where the virtual machine is located. The DHCP message includes the IP address and MAC address of the virtual machine. Further, the physical device where the virtual machine is located has the MAC address and IP address of the virtual machine, the MAC address and the IP address of the physical device where the virtual machine is located, and the specific transmission process of the DHCP message can be used in the prior art. The specific implementation process of DHCP technology is the same.

例如：在实际应用中，虚拟机是由具体的物理设备承载的，由虚拟机发出 /接收的数据需要通过物理设备进行传输。如图 2b所示，第一虚拟机和第二虚拟机可以分别由不同的物理设备 7 载，在所述虚拟网络中的虚拟机启动后，第一虚拟机和第二虚拟机都可以发起 DHCP流程，并接收 DHCP 服务器发送的 DHCP消息。比如：第二虚拟机启动后发起 DHCP流程，物理设备 2可以截获 DHCP服务器发送给第二虚拟机的 DHCP消息，在所述 DHCP消息中包括 DHCP服务器分配给第二虚拟机的 IP地址和 MAC地址，物理设备 2可以获取 DHCP消息中的 IP地址和 MAC地址，并连同物理设备 2 的 IP地址和 MAC地址，第二虚拟机所在的虚拟网络的 VNI号发送至信息服务器。通过相同的方式，物理设备 1可以获取第一虚拟机的 IP地址和 MAC 地址，并连同物理设备 1的 IP地址和 MAC地址，第一虚拟机所在的虚拟网络的 VNI号发送至信息服务器。从而实现虚拟机在启动时向信息服务器上报地址信息的过程，以使信息服务器能够获取并保存虚拟网络中所有启动的虚拟机的地址信息。 For example, in a practical application, a virtual machine is carried by a specific physical device, and data sent/received by the virtual machine needs to be transmitted through the physical device. As shown in FIG. 2b, the first virtual machine and the second virtual machine may be respectively carried by different physical devices 7, and after the virtual machines in the virtual network are started, the first virtual machine and the second virtual machine may initiate DHCP. Process and receive DHCP messages sent by the DHCP server. For example, after the second virtual machine starts, a DHCP process is initiated, and the physical device 2 can intercept the DHCP message sent by the DHCP server to the second virtual machine, where The DHCP message includes an IP address and a MAC address assigned by the DHCP server to the second virtual machine, and the physical device 2 can obtain the IP address and the MAC address in the DHCP message, and together with the IP address and MAC address of the physical device 2, the second virtual machine The VNI number of the virtual network where it is located is sent to the information server. In the same manner, the physical device 1 can obtain the IP address and MAC address of the first virtual machine, and send the VNI number of the virtual network where the first virtual machine is located to the information server along with the IP address and MAC address of the physical device 1. Thereby, the process of reporting the address information to the information server by the virtual machine at startup is implemented, so that the information server can acquire and save the address information of all the started virtual machines in the virtual network.

202 , 所述第一虚拟机所在的物理设备接收所述第一虚拟机发送的 ARP请求，从所述 ARP请求中提取所述第二虚拟机的 IP地址，根据所述第二虚拟机的 I P地址和所述第一虚拟机所在的虚拟网络的 V NI号生成所述查询请求消息并将所述查询请求消息发送给所述信息服务器。 202.

As shown in FIG. 2c, the first virtual machine may send an ARP request to the second virtual machine, where the specified character segment in the ARP request includes the IP address of the second virtual machine, and the physical device 1 where the first virtual machine is located is After intercepting the ARP request sent by the first virtual machine, the information for identifying the second virtual machine (that is, the IP address of the second virtual machine;) may be extracted from the ARP request, and according to the virtual network where the first virtual machine is located The VNI number generates a query request message, and then sends a query request message to the information server. It should be noted that: only the different virtual machines in the same virtual network can perform data interaction. Therefore, the second virtual machine that can interact with the first virtual machine can only be in the same virtual virtual machine as the first virtual machine. In the network virtual machine.
