Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for arranging a service chain, a storage medium, and an electronic apparatus.
Background
Due to the development of the Overlay network, the virtual network and the physical network are layered, and the network control of the data center becomes more flexible and has higher expansibility. However, Network communication includes various Network Service functions, such as firewall, NAT (Network Address Translation), QoS (Quality of Service), load balancer, etc., i.e., Service Function, and these middleware provides necessary Service processing functions. The traffic is flexibly, conveniently, efficiently and safely allocated to the Service Function to be processed, so as to form an SFC (Service Function Chaining), which is a problem to be solved by the Service chain.
The service chain and the network topology of the traditional network are closely coupled and complex in deployment, and when the service chain is changed and expanded, the network topology needs to be changed, and the configuration of network equipment is carried out again. The emergence of SDN (Software Defined Network) makes the service chain take place in a glowing way, and it makes the service chain have the characteristics of dynamic property, high mobility, easy change of scale, multi-tenancy, and the like. Based on the configuration of the SDN, service nodes on a linked list can be dynamically added or deleted, so that the use is convenient, and the association between network devices is decoupled. The SFC also supports context information sharing between classifiers and services, and between services, as data traffic traverses a linked list. In a conventional data service chain, data packets are often classified many times, i.e. many unpacking and packing processes. In SFC, the process is greatly reduced, and generally only one-time classification is needed, so that the whole process is more convenient and efficient.
At present, common business chain arrangement methods are roughly divided into the compiling of complex instructions and the construction of visual models, and most of data configuration processes are relatively complicated and have poor usability. The complex instruction compiling threshold is high, the efficiency is low, and the complex instruction compiling is not intuitive enough. The construction of the visualization model mostly supports the simultaneous arrangement of a single service chain, a user needs to configure network nodes strictly according to the position appointed by the model, the requirement that the user carries out multiple arrangements simultaneously and issues the network nodes at one time cannot be met, and particularly when the data volume is large, the efficiency of the arrangement of the service chain is influenced to a certain extent. In addition, the validity check of the service chain data is usually performed in the final deployment process, and if the deployment fails after a large number of arrangement operations, a user needs to perform a large number of modification operations, even before the completion of the deployment.
In view of the above problems in the related art, no effective solution exists at present.

After all the service chain data are successfully verified, the next service chain data can be updated, so that large-scale modification operation possibly caused by deployment after a large number of service chains are arranged at the same time is avoided.
The present application is exemplified below with reference to alternative embodiments thereof;
this optional embodiment provides a visual service chain arrangement method, fig. 2 is a flowchart of the visual service chain arrangement method according to the embodiment of the present invention, and as shown in fig. 2, the method includes the steps of:
step S201: initializing a service topology component and a tenant table, and loading tenant information;
the initialized service chain arranging interface is a topological component constructed by AngularJS. The topology component supports functions of displaying, arranging, exporting and the like of network topology, and the upper left corner of the topology component comprises a tenant search box. And clicking a tenant search box, and popping up a tenant table at the lower part of the search box to display all tenant information acquired from the server, wherein the tenant information comprises the number of the currently searched tenants, the tenant ID and the tenant name.
Step S202, selecting routing data under a certain tenant and loading service topology;
the user selects a certain tenant in the tenant table, the route data corresponding to the current tenant is obtained from the server, and the tenant table displays the current tenant and the corresponding route information instead. The routing information table comprises the number of routes searched currently, a routing ID and a routing name, the top of the table displays the tenant ID and the tenant name of the current tenant, and the current tenant can be returned to the tenant table after clicking.
The user selects a certain route, corresponding service chain data are obtained from the server side according to the current route ID, and the topology component constructs service topology according to the obtained service chain data. All service topologies are arranged on the topology component from top to bottom, and each service topology represents a service chain which is configured and completed. The service topology extends from left to right, and the leftmost node of the drainage source topology represents all drainage sources of the current service chain. The middle is the intermediate equipment node passing through in sequence, and the direction of the drainage and the equipment and the port passing through in sequence can be seen clearly. The right-most side is the destination topology node of the drainage, which represents all drainage end points of the current traffic chain. Clicking any node in the service topology, popping up a detail table on the right side of the topology component to show detailed information of the current service chain, wherein the detailed information mainly comprises service chain IDs, drainage types, quintuple information of all drainage sources and destinations, intermediate equipment, port information and the like.
Step S203, starting service chain arrangement, initializing a service chain topology interface and loading service chain topology;
and clicking a service chain arrangement button or a service chain arrangement button in a service topology node right-click menu, popping up a modal frame on a page, and displaying a service chain topology component. All the service chain topologies are arranged on the topology component from top to bottom, and each service chain topology represents a service chain which is configured or is being configured. The service chain topology mainly comprises a classifier and a port, and a drainage object and a drainage intermediate device port are sequentially represented. Each service chain topology contains at least one classfier and at least one port. The leftmost side of the service chain topology, i.e. the starting point of the topology graph, is one or more classsizers, all of which point to the first port. All ports are arranged in a form similar to a singly linked list, and mark a drainage route for configuring a service chain, and the drainage route corresponds to an intermediate node of a service topology. And clicking the topology node, popping up a detail table on the right side of the topology component, and displaying specific configuration information of the current service chain, wherein the specific configuration information mainly comprises a service chain ID, a classfier, a port and the like. In addition, the topology in the service topology component corresponds to the topology in the service chain topology component one to one, skipping and highlight display can be carried out through a right-click menu button of the node, and a user can quickly find corresponding data in a plurality of service chains.
The service chain topology component maintains a cache data structure for recording all service chain data of the current configuration, and for related calculation and final deployment updating in the orchestration operation. The cache mainly records node position information, node configuration data, node link information and the like of all service link topologies.
Step S204, dragging the topology node or clicking the right-click menu option of the topology node to perform service chain arrangement;
wherein, the step S204 may further comprise the following method steps:
step S204-11, judging which service chain topology the new node belongs to according to the node position;
step S204-12, determining the specific position of the node according to the type of the node and the cache data of the current service chain;
step S204-13, automatically generating a topological link related to the newly-built node;
step S204-14, popping up a node attribute table, and perfecting the node attribute to complete node configuration;
and step S204-15, judging the integrity of the currently arranged service chain topology and the data legality, and feeding back the result to the user.
That is, for the above steps S204-11 to S204-15, first, the topology node in the left topology node list is dragged to add a new service chain topology node, and after the dragging action is finished, the system will obtain the coordinate data of the new node in the service chain topology component. And then, comparing the coordinate data of the new node with the coordinate ranges of all configured service chain topologies, wherein if the new coordinate is located in the coordinate range of a certain service chain topology, the new node belongs to a newly added node of the service chain topology, and if the new coordinate is not located in the coordinate range of any service chain topology, the new service chain topology is created, and the new node belongs to the node of the new service chain topology. And the coordinate range of each service chain topology is obtained by calculating the range threshold value and the configured node data of the current service chain. Firstly, edge nodes around the current service chain are obtained according to cache data, and then the coordinate range of the current service chain can be obtained by adding the coordinate of the edge node to a range threshold value. The present embodiment does not specifically limit the range threshold of the topology.
Fig. 3 is a schematic diagram of service orchestration according to an embodiment of the present invention, and as shown in fig. 3, a dragged new node1 is located in a coordinate range of a service chain SFC1, and is a new added node of a configured service chain SFC 1. The dragged new node2 is located in the coordinate range of the service chain SFC2 and is the new node of the configured service chain SFC 2. And if the dragged new node3 does not belong to any configured service chain topological range, newly building a service chain SFC3, and taking the node3 as the first topological node of the newly built service chain. When the topology is dragged to be within the coordinate range of a certain service chain topology, the service chain topology node flickers to prompt. And each service chain topology does not have an overlapped coordinate range, so that collision is avoided.
After determining which service chain topology the newly-built service chain topology node belongs to, it is required to calculate the specific position of the new node in the current service chain and automatically generate a topology link. If the new node is a topology node of the new service chain, the new service chain is created at the lowest side of the topology, and the new node is located at the starting position of the topology of the new service chain, such as node3 node in fig. 3. And if the new node is a newly added node of the configured service chain, confirming the link and the position information according to the node type and the cache information of the current service chain. When the node type is classfier, a topology link is automatically generated, so that the node points to a configured first port node, and indicates that the current drainage object uses a pointing intermediate device node, such as a node1 node in fig. 3; and if no port node is built, no link is created, and the current drainage object is represented to have no intermediate device node. All classifier nodes are located at the leftmost side of the current topology, arranged from top to bottom, and the newly created classifier node is located at the lowermost side. Meanwhile, a classifier form is popped up on the right side of the topological component, and a user fills information such as a source IP (Internet protocol), a destination IP (Internet protocol) and a port of drainage to configure and complete a classifier node. When the node type is port, if the node is a first created port node and a newly-built classifier node exists, the link points to the node from all configured classifier nodes, and the node is a first intermediate device node and a drainage object exists; if the node is the first created port node and no newly-created classfier node exists, no link is created, and the node is the first intermediate equipment node and no drainage object exists; if the node is not the first port node created, the link is pointed to by a configured port node on the link, which means that the node is an intermediate device node but is not the first intermediate device node in the flow-directing route, such as node2 node in fig. 3. All port nodes are arranged from left to right in a singly linked list form, and the newly created port node is positioned at the rightmost side. Meanwhile, a port form is popped up on the right side of the topology component, and a user can configure and complete a port node by selecting an intermediate device port through which drainage passes.
When a service chain is newly built, a user can also update the position of a topological node in a dragging mode, the operation flow is basically the same as the flow of the newly built node, and further explanation is not provided here. All the options in the right-click menu of the topological nodes support the attribute modification and deletion operation of a certain node in the service chain, and the modified topological nodes and the newly added topological nodes are presented in different colors, so that the user can distinguish the nodes conveniently.
Step S205, verifying the validity of the data after each editing operation in real time and feeding back the data to the user;
after each editing operation, the system updates the cached service chain data according to the current operation and verifies the integrity of the service chain data, and then sends an Ajax asynchronous request to a background to perform real-time verification and feedback of the configuration data. The editing operation needing to be verified comprises the following steps: dragging the topology node, configuring and updating parameters of the topology node, deleting the topology node of the service chain, deleting the service chain and the like. Taking fig. 3 as an example, the specific verification steps include: judging the integrity of the current service chain topology, namely each service chain topology must contain at least one port and classfier node, and prompting the incomplete service chain; distinguishing the topological nodes without configuration parameters in different colors to prompt a user to perfect the attributes of the topological nodes; and for the service chain with the complete topological structure, the service chain detail data is packaged according to the cached topological data, an asynchronous request is sent to the server, and whether the current service chain data can be normally deployed is checked. And modifying and feeding back the related service chain according to the request return result. And after all the service chain data are successfully verified, updating the service chain data. Therefore, large-scale modification operation which is possibly caused by deployment after a large number of service chains are simultaneously arranged is avoided.
Step S206, a service chain is deployed;
and after the complete service chain information is configured, clicking a deployment button of the service chain topological component, integrating service chain data on the topological component by the front end, sending a service chain updating request to the server side, and performing service chain adding, deleting and modifying operation. And after the deployment is successful, the topology component presents the latest service chain information.
