Description
Technical Field
The invention relates to a cloud computing technology, in particular to a method and a system for distributing a virtualized network address of a data center and a directory server.
Background
With the wide application of cloud computing technology, a cloud computing data center network is greatly different from a traditional data center network, and the scale of the cloud computing data center network is larger than that of the traditional data center network, so that the traditional two-layer technology has the problem of expansibility in the cloud computing data center network.
Fig. 1 is a diagram of a virtualized overlay network of a conventional data center network, in fig. 1, a VM is a virtual machine, an NVE is a network virtual boundary, a dotted line represents data flow, a solid line represents a connection relationship between devices, original data is encapsulated on the NVE, data transmission is performed depending on a Router (Router) of an intermediate overlay network, a mapping relationship between an outer layer address and an inner layer address needs to be stored on the NVE, and a self-learning manner is adopted to establish and update a MAC address table. The overlay network adopts a Layer 2 Over Layer3 mode, the encapsulation message of the inner Layer is an Ethernet message, the outer Layer can be a network Layer message header, in order to realize the identification of the protocol stack, a UDP message header is encapsulated between the outer Layer network Layer and the inner Layer Ethernet Layer, and can also be in the form of encapsulating a TCP message header and the like, the message address of the inner Layer is an MAC address, and the address of the outer Layer is an IP address. Data transmission in an overlay network is routed dependent on IP addresses. The realization of the overlay network solves the problem of expansibility of the traditional two-layer data center network, and the problems of network intercommunication across data centers, rapid migration of VMs and the like.
For the cloud computing data center network with the superimposed layer, the traditional Media Access Control (MAC) address self-learning mode cannot meet the requirement, for the following reasons: (1) under the MAC address self-learning mode, the updating of an MAC address table depends on the aging time of an MAC address, the updating of the MAC address is slow, and the loss of data messages is caused, and in a cloud computing data center network, due to the fact that more VM migration applications exist and the requirement of the data center network on the reliability is high, the slow updating of the MAC address cannot meet the requirement of the cloud computing data center network; (2) the MAC address learning mode adopts a broadcast or multicast mode for the first packet forwarding, and because the network scale of the cloud computing data center is much larger than that of the traditional two-layer data center, the transmission mode of the first packet forwarding can cause a large amount of broadcast or multicast messages to be formed in the cloud computing data center, thereby wasting network bandwidth and reducing the bandwidth utilization rate of the network.
In order to solve the above problem of the cloud computing data center network, the industry provides a Directory Server (Directory Server) mode to store the MAC address and IP address mapping of a user, the Directory Server can work in a Push (Push) mode and a Pull (Pull) mode, the Pull mode is to reply address information required by a request to a network virtual boundary after receiving a request message of the network virtual boundary, and the Push mode is to actively send the address information to one or more network virtual boundaries by the Directory Server.
However, such a method of using the directory server to store the mapping between the MAC address and the IP address of the user cannot perform finer address differentiation, for example, in the Push method, the directory server may send address information to a plurality of network virtual boundaries, and such an address distribution method may generate unnecessary distribution messages and messages, which results in waste of network bandwidth.

17. The distribution system of claim 13, wherein the address distribution module is specifically configured to receive a network address request message that is sent by a network virtual boundary and carries a tenant identifier, search for a corresponding mapping entry according to the tenant identifier carried in the network address request message, and distribute network address information in the mapping entry to the network virtual boundary through a response message, when the address distribution module operates in a Pull mode.
18. A directory server, the directory server comprising: the system comprises an address registration module and an address distribution module; wherein,
the address registration module is used for receiving and storing a network address registration message which is sent by the network virtual boundary and carries the tenant identification and the network address information;
and the address distribution module is used for distributing the network address information to the network virtual boundary related to the tenant identification only when distributing the network address information to the network virtual boundary.
19. The directory server of claim 18, wherein when the directory server is a centralized server, the address registration module is specifically configured to receive a network address registration message that is sent by a network virtual boundary and carries a tenant identifier and network address information, and store the network address information and the tenant identifier in the network address registration message in the form of a mapping entry.
20. The directory server according to claim 18, wherein when the directory server is a distributed server, the address registration module of the directory server that receives the network address registration message is specifically configured to find the directory server that stores the mapping entry corresponding to the tenant identifier according to a distributed algorithm, and send the network address information and the tenant identifier in the network address registration message to the found directory server through a message;
the address registration module of the directory server is specifically configured to store the network address information and the tenant identifier in the form of a mapping entry.
21. The directory server of claim 18, wherein the address distribution module is specifically configured to, when operating in a Push mode, distribute, through an advertisement packet, network address information to a network virtual boundary associated with a tenant identity in a datacenter network after the address registration module stores the network address information and the tenant identity in a network address registration message in the form of a mapping entry.
22. The directory server of claim 18, wherein the address distribution module is specifically configured to receive a network address request message carrying a tenant identifier sent by a network virtual boundary in a Pull manner, find a corresponding mapping entry according to the tenant identifier carried in the network address request message, and distribute network address information in the mapping entry to the network virtual boundary through a response message.
