Carry out overall identification transmission net slice example, establishes E2E network slice example and transmission net in E2E network slice management function
It is sliced example and the incidence relation of other sub- slices, an E2E network slice can transmit net by one or more and cut
Piece is serviced.
It is illustrated below with reference to specific implement scene,
Firstly, a kind of transmission net slice management framework provided in an embodiment of the present invention is introduced.
Transmission net is sliced management framework as shown in Figure 1, is configured with different Client Context on SDN controller
(user situation), SDN controller can will transmit network money by the process of virtualization according to different Client Context
Source virtual abstraction is used at different virtual networks to user corresponding to Client Contex, for example, Client
Context1, Client Context 2, Client Context 3 may be respectively used for virtual abstraction go out virtual network VN1,
VN2, VN3, different virtual networks can be used for carrying different types of mobile network E2E slice.Transmit net slice management
Function establishes transmission net slice information library, all transmission net slices in the management domain for storing the management function
Information.Transmission net need the type that is sliced according to E2E network established in corresponding virtual network different service connections come to
The different instances of the type E2E network slice provide connection service.It is adopted between transmission net slice management function and SDN controller
With existing SDN controller api interface.Following embodiment is based on framework shown in Fig. 1 and is described.
Embodiment one:
As shown in Fig. 2, establishing the stream of incidence relation using existing transmission net slice example and with E2E network slice example
Journey is as follows:
(1) E2E network slice management function sends request message instruction distribution transmission to transmission net slice management function
Net slice carries the ID of E2E network slice, the E2E network slice type of service of required support, E2E network is needed to be sliced
Access-in point information and required connection the information such as QoS demand.
(2) transmission net slice management function is selected in transmission slice information library according to the demand that E2E network is sliced example
The transmission net slice example of meet demand is selected, slice selection course includes:
A. it is selected to support the E2E network slice type in transmission net slice information library according to E2E network slice type
Transmission net be sliced example
B. the service in comparison E2E network slice example demand in all Service Access Points and transmission net slice information connects
Enter point list, guarantees that the service of selected transmission net slice example and access point list contain E2E network slice example
All Service Access Points in demand
C. the qos parameter of the QoS demand of comparison transmission net E2E network slice example and transmission net slice example, including
Whether bandwidth is enough, and whether delay meets, and determines the qos parameter meet demand of selected transmission net slice example.
D. the protection plan that service is connected in Preservation tactics required for E2E network is sliced and transmission net slice example is determined
It is slightly consistent.
(1) transmission net slice management function is to SDN control belonging to virtual network used in transmission net slice example
Device processed sends the request for updating connection service, carries the information such as the information for needing increased Service Access Point and required connection performance.
(2) the corresponding network edge node of the corresponding SDN controller instruction virtual network of virtual network updates connection, including
The relevant information of newly-increased Service Access Point is configured to corresponding network edge node, and is connected and bound with this.The process
When under the network structure of the multi-layer multi-domain of transmission net, further realized by multilayer director.
(3) transmission net slice management function increases in the corresponding E2E network slice example of transmission net slice example
The information such as the new ID of E2E network slice example.
(4) transmission net slice management function will transmit net slice example ID and be sent to E2E network slice management system.
Embodiment two:
As shown in figure 3, newly-increased transmission net is sliced example and establishes the process of incidence relation such as with E2E network slice example
Under:
(1) E2E network slice management function sends request message instruction distribution transmission to transmission net slice management function
Network slice, carry E2E network slice ID, required support type of service, need E2E network access-in point information and
The information such as the QoS demand of required connection.
(2) transmission net slice management function does not have in transmission slice information library according to the demand that E2E network is sliced example
There is the transmission net slice example for choosing meet demand, wherein selection course and embodiment one are identical.
(3) transmission net slice management function transmission net slice management function is unique to transmission net slice example allocation
ID, and corresponding virtual network is selected according to the type of service for the E2E network slice supported, and to belonging to the virtual network
SDN controller sends creation connection service request, the information such as Service Access Point and connection performance for connecting needed for carrying.
(4) the corresponding SDN controller of virtual network establishes new connection on the corresponding Internet resources of virtual network, and will
Connection ID and connection relevant information feed back to transmission net slice management function.Network of the process in the multi-layer multi-domain of transmission net
Under structure, further realized by multilayer director.
(5) letter of transmission net slice management function creation transmission net slice example in transmission net slice information library
Breath, the incidence relation including transmission net slice example and E2E network slice example, specifying information have: transmission net slice is real
Example ID, E2E network slice example ID, the ID of used VN and the ID of connection service for being included etc..
(6) transmission net slice management function will transmit net slice example ID and be sent to E2E network slice management system.
