SASE services for private mobile network
Some embodiments provide a method for implementing a software-defined private mobile network (SD-PMN) for an entity. At a physical location of the entity, the method deploys a first set of control plane components for the SD-PMN, the first set of control plane components including a security gateway, a user-plane function (UPF), an AMF (access and mobility management function), and an SMF (session management function). At an SD-WAN (software-defined wide area network) PoP (point of presence) belonging to a provider of the SD-PMN, the method deploys a second set of control plane components for the SD-PMN that includes a subscriber database that stores data associated with users of the SD-PMN. The method uses an SD-WAN edge router located at the physical location of the entity and a SD-WAN gateway located at the SD-WAN PoP to establish a connection from the physical location of the entity to the SD-WAN PoP.
1. A method of providing access to a plurality of cloud-delivered services for a multi-tenant SD-PMN (software-defined private mobile network), the SD-PMN spanning at least a first site belonging to a first entity and a PMN-provider second site, the first entity's first site comprising a first portion of the SD-PMN that includes one or more physical access points for connecting a plurality of user devices at the first entity's first site to the SD-PMN and one or more data plane components of the SD-PMN, the method comprising:
at a gateway router deployed in the PMN-provider second site:
receiving a data message from a source located at the first entity's first site;
determining that the received data message should be processed by a service chain that performs a set of one or more cloud-delivered services before the data message is forwarded to a destination of the data message;
forwarding the data message to the service chain that performs the set of one or more cloud-delivered services for processing; and
upon receiving the processed data message from the service chain, forwarding the processed data message to the destination of the data message.
2. The method of claim 1 , wherein:
the PMN-provider second site comprises a SASE (secure access service edge) PoP (point of presence);
the service chain comprises a SASE service chain located in the SASE PoP; and
forwarding the data message to the service chain comprises forwarding the data message to the SASE service chain in the SASE PoP.
3. The method of claim 1 , wherein forwarding the data message to the service chain comprises forwarding the data message to a third site that hosts the service chain.
4. The method of claim 1 , wherein the source of the data message comprises a user device from the plurality of user devices at the first entity's first site.
5. The method of claim 4 , wherein receiving the data message from the source located at the first entity's first site comprises receiving the data message from an edge router deployed to the first entity's first site to perform data message forwarding within the first entity's first site and between the first entity's first site and a plurality of destinations external to the first entity's first site.
6. The method of claim 5 , wherein the data message traverses a set of elements between the user device and the edge router deployed to the first entity's first set, the set of elements comprising at least one physical access point deployed at the first entity's first site and a user plane function (UPF) deployed at the first entity's first site.
7. The method of claim 1 , wherein the SD-PMN is a multi-tenant SD-PMN, wherein the first entity is one of a plurality of entities serviced by the SD-PMN.
8. The method of claim 7 , wherein the first entity's first site is one of a plurality of sites belonging to the first entity.
9. The method of claim 8 , wherein each entity in the plurality of entities serviced by the SD-PMN has at least one site.
10. The method of claim 1 , wherein the set of one or more cloud-delivered services comprises a firewall, a secure web gateway, a zero-trust network access service, and a threat detection service.
11. A non-transitory machine readable medium storing a program for execution by a set of processing units, the program for a gateway router that provides access to a plurality of cloud-delivered services for a multi-tenant SD-PMN (software-defined private mobile network), the SD-PMN spanning at least a first site belonging to a first entity and a PMN-provider second site to which the gateway router is deployed, the first entity's first site comprising a first portion of the SD-PMN that includes one or more physical access points for connecting a plurality of user devices at the first entity's first site to the SD-PMN and one or more data plane components of the SD-PMN, the program comprising sets of instructions for:
receiving a data message from a source located at the first entity's first site;
determining that the received data message should be processed by a service chain that performs a set of one or more cloud-delivered services before the data message is forwarded to a destination of the data message;
forwarding the data message to the service chain that performs the set of one or more cloud-delivered services for processing; and
upon receiving the processed data message from the service chain, forwarding the processed data message to the destination of the data message.
12. The non-transitory machine readable medium of claim 11 , wherein:
the PMN-provider second site comprises a SASE (secure access service edge) PoP (point of presence);
the service chain comprises a SASE service chain located in the SASE PoP; and
the set of instructions forwarding the data message to the service chain comprises a set of instructions forwarding the data message to the SASE service chain in the SASE PoP.
13. The non-transitory machine readable medium of claim 11 , wherein the set of instructions forwarding the data message to the service chain comprises a set of instructions forwarding the data message to a third site that hosts the service chain.
14. The non-transitory machine readable medium of claim 11 , wherein the source of the data message comprises a user device from the plurality of user devices at the first entity's first site.
15. The non-transitory machine readable medium of claim 14 , wherein the set of instructions for receiving the data message from the source located at the first entity's first site comprises a set of instructions for receiving the data message from an edge router deployed to the first entity's first site to perform data message forwarding within the first entity's first site and between the first entity's first site and a plurality of destinations external to the first entity's first site.
16. The non-transitory machine readable medium of claim 15 , wherein the data message traverses a set of elements between the user device and the edge router deployed to the first entity's first set, the set of elements comprising at least one physical access point deployed at the first entity's first site and a user plane function (UPF) deployed at the first entity's first site.
17. The non-transitory machine readable medium of claim 11 , wherein the SD-PMN is a multi-tenant SD-PMN, wherein the first entity is one of a plurality of entities serviced by the SD-PMN.
18. The non-transitory machine readable medium of claim 17 , wherein the first entity's first site is one of a plurality of sites belonging to the first entity.
19. The non-transitory machine readable medium of claim 18 , wherein each entity in the plurality of entities serviced by the SD-PMN has at least one site.
20. The non-transitory machine readable medium of claim 11 , wherein the set of one or more cloud-delivered services comprises a firewall, a secure web gateway, a zero-trust network access service, and a threat detection service.
