Embodiment
The invention will be further described below in conjunction with embodiment.
A kind of method that realizes the VDI Network Load Balance of the present invention comprises user's mobile device and the VDI that supplies the VD access service, and the user adopts the set of remote desktop agreement protocol to insert VD by the teledata net, may further comprise the steps:
Construction step, between user's mobile device and VDI, make up a VSSN, this VSSN comes the SLA index of real-time monitor user ' mobile device and VDI on-premise network by some NLB, NLB is deployed in the VDI infrastructure, NLB realizes 2 layers and above medium Ethernet protocol by the VDE interface, constitute VSSN, form the irrelevant nerve of a covering (Overlay Network) of physical network, VSSN adopts the heartbeat mode to check the SLA index of each VDI Access Network and user's mobile device;
Automatically select step, automatically select to possess the VDI network of excellent SLA deliverability by VSSN, promptly when active user SLA index was not enough, VSSN write down automatically and selects a VDI supply system that meets SLA or best SLA index, forms the candidate of new VDI Access Network;
Migration step, Autonomic Migration Framework VD is to new VDI Access Network, promptly when continuing to keep active user's access service, copy to new VDI Access Network or create a new service VD inserting VD at this VDI Access Network, and the support data of migration current active session and VD, after this VD is ready, active user's remote desktop agreement protocol set is transferred to this VD by virtual distributed Ethernet mechanism, continue the VDI service, when creating a new service VD, adopt the migration mechanism of virtual machine manager.
See also Fig. 2, show framework of the present invention, via the additional VSSN1 that disposes, system selects to satisfy the Access Network 2 of SLA condition automatically.The registration VD31 that the original subscriber registers in the net 3 migrates to Access Network 2 through the VSSN1 control command, move the current active session simultaneously and support data, active user's remote desktop agreement protocol collection is migrated to Ad-hoc VD21 new in the Access Network, continues its VDI access service.Concrete steps comprise:
Step S1, NLB4 realizes 2 layers and above medium Ethernet protocol by the VDE interface, constitutes VSSN1, NLB4 is deployed in the VDI infrastructure 22;
Step S2, VSSN1 adopt heartbeat (Heart Beat) mode to check the SLA index of each VDI Access Network 2 and customer mobile terminal 5;
Step S3, when current service VD can not satisfy SLA, VSSN1 will select (or establishment) service VD at new VDI Access Network 2, form Ad-Hoc VD21;
Step S4, all active session of current VD and support data are moved simultaneously;
Step S5, ready as Ad-Hoc VD21, VSSN1 migrates to Ad-hoc VD21 with Ethernet 2 layer protocols of user's remote desktop agreement protocol collection by VDE, continues the VDI business;
The registration VD31 that step S6, original subscriber register in the net stops service;
Step S7, VSSN1 back up all Ad-Hoc VD21 states;
Step S8 when Ad-Hoc VD21 conversation end, carries out data sync between former registration VD31 and Ad-Hoc VD21;
Step S9 when the user logins the VD business next time, returns step S2.
See also Fig. 3, show the state of VDI Access Network supply service of the present invention, in the figure, the VDI that the user registers the service provider in the net inserts far away apart from portable terminal, therefore, by technical scheme of the present invention, the VDI that creates new service provider at nearer Access Network inserts, among the figure, the user registers NLB4 in the net with the NLB4 of its state transition to Access Network, and data are carried out synchronous migration, and among the figure, the Ad-hoc VD21 in the Access Network is the new VD that creates.
When needs are created a new Ad-hoc VD21, adopt the migration mechanism (Migration) of virtual machine manager (VMM); User's mobile device obtains the support of local disposition VDI network under the support of local GGSN61 of Access Network and SGSN62; User VD inserts and need not to cross over a plurality of networks and register net 3 to the user, then multiplexing local VDI network has alleviated network burden so greatly.
See also Fig. 4, show the schematic diagram of 2 layers of Ethernet protocols realization of VSSN1, among the figure, NLB4 constructs IP redirects mechanism by 2 layers of Ethernet virtual media interface of VDE: promptly MAC and the PORT of user's remote desktop agreement protocol collection by the 2 layers of mechanism IP level that realizes long-range VD is redirected the User IP protocol transparent.This agreement realizes teledata control protocol collection and other agreements, as FTP (file transfer protocol (FTP)), HTTP (HTML (Hypertext Markup Language)), RTP (real time transport protocol), SSH (security protocol) etc., the automatic IP agreement of user's remote desktop agreement protocol collection is redirected.
NLB4 is deployed in one and the VMM of a selection only, in order to realize gateway virtual machine controller (Gateway VMM) function of this VDI Access Network 2.
See also Fig. 5, there is shown in the migration step of the present invention, Autonomic Migration Framework VD is during to new VDI Access Network, schematic diagram when the application layer of its data migration is end-to-end application layer protocol, when the application layer of VD support data migration is end-to-end (Peer-to-Peer) application layer protocol, dynamically obtain VD and support data, promptly new VDI Access Network is directly obtained VD from original VDI network and is supported data.
See also Fig. 6, there is shown in the migration step of the present invention, Autonomic Migration Framework VD is during to new VDI Access Network, schematic diagram when the application layer of its data migration is data replication application layer protocol, the application layer that supports the data migration as VD is that data are when duplicating (Replication) application layer protocol, duplicate VD and support data, the VD that promptly new VDI Access Network duplicates original VDI network supports data.
See also Fig. 7, there is shown in the migration step of the present invention, Autonomic Migration Framework VD is during to new VDI Access Network, schematic diagram when the application layer of its data migration is the layer of structure application layer protocol, when the application layer of VD support data migration is layer of structureization (Hierarchy) application layer protocol, dynamically or static state obtain VD and support data, promptly new VDI Access Network is dynamically or staticly obtain VD from original VDI network and support data.
In sum, the present invention with virtual desktop management system deployment in cordless communication network, in VDI, dispose NLB, but NLB realizes the virtual desktop of dynamic migration, move the current active session simultaneously and support data, realize the gateway control function of virtual desktop management system by VSSN, network sla between realization user's mobile device and the virtual desktop management system gateway is monitored in real time, select and exchange virtual desktop management grid, migrated users remote desktop connection protocol is gathered to virtual desktop, and keeps continuing of all active session.
Below embodiment has been described in detail the present invention in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the present invention according to the above description.Thereby some details among the embodiment should not constitute limitation of the invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
