Description
Technical field
The present invention relates to network technology, relate in particular to a kind of remote assistance retransmission method and system.
Background technology
The rise of cloud computing is little by little changing the academic boundary of whole computer and industrial circle, and the virtual core element that becomes data center of future generation that just developing rapidly, and this variation also brings new challenge to network.Cost has been saved in early stage server 20 virtual deployment greatly, and has strengthened simultaneously deployment flexibility and adaptability.Along with virtualization software is ripe gradually, simple server 20 is integrated to begin to tend to relate to the strategy that server 20 environment is carried out fully again framework.Next Generation Telecom Service device 20 hardware are with the virtual support machine, and most of software has just been considered virtual when design.Some challenges that bring to network are: to the requirement of bandwidth and exchange capacity, greatly improved Topological Complexity, and made complex management, because virtual difference of having blured between physics and virtual, network and server 20 and data and the storage networking.
Virtual machine is more prone to dispose than legacy operating system or application program, and enterprise can also be by coming Cost reduction at a plurality of virtual machines of individual server 20 operations.But virtual also have a shortcoming, in network facet, although the virtual quantity that reduces physical server 20, the virtual quantity that has also increased virtual unit and the network equipment.From the angle of switch, there are some differences in virtual network port and physical network port.In addition, the increase of virtual machine makes the network traffics surge, no matter is at network core or edge, causes potential network bottleneck problem and management problems.
The simplicity of server 20 will cause the complicated of network, and at first, the network complexity of increase can affect performance.Except increasing the network equipment, the virtual level that increases switching fabric has increased retardance, function loss and management complexity.Most of data centers use three-decker: edge switch, convergence switch and frame topcross are changed planes (TOR) or wire laying mode switch EOR.Hypervisor has increased by one to be had software switch annex layer and comes managing internal hypervisor flow.Some server 20 may use has the virtualized intelligent NIC of hardware port, and blade chassis often has switch module, and each module can increase another exchange layer.Secondly, the integrated of the virtual machine on the physical server 20 can impact exchange extensibility and performance.In addition, because virtual switch is the 2nd layer of operation, the increase of virtual machine will change the local area network (LAN) topology, allows it become larger.This also makes a lot of problems that design of local area network teacher meets with before edge switch occurs reappear problems such as broadcast traffic expense and address table blast.The integrated rate of virtual machine has also limited the validity of VLAN subregion.Because virtual switch more similarly is the bridge that is connected to external network the 2nd layer of operation, and because the VLAN label is based on port, any application-specific VLAN is visible for the virtual machine in the system.Therefore, if more multi-dummy machine is shared identical ethernet port, and the different application program on these virtual machines is derived from different VLAN, and then each port will need the access rights of multi-VLAN more, and this has limited validity greatly.Again, software switch makes management and complicated safely.Network monitoring, management, flow report and security tool Application standard agreement are moved at physical port, but along with increasing flow exchanges between hypervisor, these instruments have lost the visuality to a large amount of network activitys.Some suppliers allow its monitoring and analysis software make to regain visuality at virtual machine, but these all are proprietary solutions, usually can only support one or two hypervisor supplier, and usually need extra certificate cost.
For solving the above virtual problem of bringing to network, the various solutions of the numerous and confused proposition of each manufacturer, the most traditional is virtual switch, its advantage is purely to realize by software, do not need extra hardware device, but performance and problem of management can't be avoided, a kind of alternative method is exactly virtual ether bridge (VEB), it moves to an intelligent NIC (network interface card with bridging functionality, Network Interface Card) on, this NIC supports so-called single I/O virtual (SR-IOV).SR-IOV is divided into a plurality of virtual NIC with intelligent NIC, and each virtual machine distributes a NIC, and independently memory headroom, interruption and DMA stream are realized by providing for each virtual machine for it.This allows bridge joint to occur in hardware, rather than in hypervisor.But because relatively poor interoperability between the NIC, and the scalability problem that brings along with the virtual machine quantity increase of every station server 20 carryings, the favor that this solution is not won the market.Another solution is to abandon virtual switch fully, and function of exchange is moved back into edge device.Thereby two ieee standard: 802.1Qbg and 802.1Qbh have been produced.After Hewlett-Packard released its correlation technique, this standard was also sometimes referred to as virtual ethernet port trunking (VEPA), although in fact the VEPA of Hewlett-Packard comprises extra proprietary feature.
The purpose of EVB (Edge Virtual Bridging, the virtual bridge in edge) is to allow a plurality of virtual machines to share a common port, and obtains service from outside bridge simultaneously.Generally, ethernet frame can't go back to that interface that they are come in, and this action can cause the network port to form loop.EVB provides a standard method to solve this problem.As a relatively simple protocol extension, EVB is more attractive, because it can be deployed on the existing hardware, and only needs the software of switch and hypervisor is upgraded.But, EVB also is the starting stage, it can not solve the policy management problem, and can bring the more burden of multicast and flux of multicast to switch, 802.1Qbh solves this problem by the bridge port expansion just, although 802.1Qbg can not revise the bottom ethernet packet, but 802.1Qbh ports-Extending standard has increased a label, similarly be standard VLAN label, allow network traffics to be mapped to particular virtual machine, and when virtual machine tracking virtual machine during at Network Mobility.
As mentioned above, although virtual switch is suitable for small-scale data center, from the point of long-term development, have still that retardance, function loss, complex management, broadcast traffic expense are large, the problems such as address table blast, poor expandability and poor performance.The problems such as 802.1Qbg and 802.1Qbh can solve performance and problem of management to a certain extent, but needs special hardware device support, and cost is higher, and autgmentability is poor.
