More specifically, the present embodiment provides a method for implementing a cloud gateway to share a DHCP (Dynamic Host Configuration Protocol ) address pool in a home in different places, and some technical terms related to this embodiment are explained as follows:

Dynamic host configuration protocol DHCP is a standard protocol that allows servers to dynamically allocate IP (Internet Protocol ) addresses and configuration information to clients, DHCP is an important network protocol for local area networks, operating using UDP (User Datagram Protocol ) protocols, and is mainly used for automatically allocating IP addresses to internal networks or network service providers, as a means of central management for all computers for users or internal network administrators, and accepting IP leases for internal network users.

In a conventional home network, home ONU (Optical Network Unit ) devices of a telecom operator or home router devices purchased by users provide DHCP services for home mobile phone terminals, computer terminals, internet of things terminals, and the like. In the cloud broadband network architecture, the DHCP capability of the ONU device is moved up to a cloud gateway, the cloud gateway uniformly provides the DHCP service of the home terminal of a certain zone, and in the cloud gateway, QINQ (a technology of adding a layer of 802.1Q tag on the basis of the original 802.1Q message) is used to distinguish different families.

In the prior art, when the address allocation of the home terminal in different places is realized, the CIDR technology is mostly adopted, the fixed division mode of traditional class A, class B and class C IP addresses is broken through by introducing the concept of variable-length subnet masks, and a 'diagonal notation' is used, for example, a mask bit is 24 bits, the existing home terminal mostly adopts a method of acquiring a class C address, one class C address is a network number in four sections of numbers of the IP address, the first three sections of numbers are numbers of a local computer, the remaining section of numbers are numbers of a local computer, and the class C address comprises class A addresses of 1.0.0.1-126.255.255.254, and class B addresses of 128.0.0.0.255.255.254, class D addresses of 224.0.1-239.255.255.254, and class E addresses of 240.0.0.1-255.255.254.

In the cloud gateway scene, the embodiment realizes the sharing of the address pool by the home DHCP in different places, so that the home terminals in different places still keep the use mode of the class C address, the incompatibility condition of the terminals is avoided, the original gateway address is adopted by different families, the problem of network interruption is avoided, and the use cognition of users is kept.

the second cloud gateway obtains local network addresses which are distributed for the terminals under the local sharing account number and the remote sharing account number according to local network address sharing distribution definition;

And the second cloud gateway excludes the allocated local area network address and allocates a new local area network address according to the local area network address sharing allocation definition for the terminal which allocates the address for the new request under the local sharing account and the remote sharing account.

In this embodiment, the method may be applied to two or more cloud gateways to provide DHCP services for terminals of multiple households of two or more slices, where a scene of sharing a local area network for two or more households of the two or more slices is required, at this time, in each cloud gateway, an account is created for each household of the slice where the cloud gateway is located, the account is marked as a shared account for the household needing to share the local area network, and a local area network address sharing allocation definition of two or more shared accounts is defined, sharing allocation of local area network addresses is achieved through interaction of two cloud gateways, one cloud gateway is responsible for address allocation, and the other cloud gateways receive the allocated addresses.

In one embodiment, the method specifically includes:

the method comprises the steps that a fourth cloud gateway obtains a local sharing account number of a local area network address which is to be shared with a fifth cloud gateway and uses the same gateway address, and a remote sharing account number of the local area network address which is to be shared with the fourth cloud gateway and uses the same gateway address;

The fourth cloud gateway obtains a local area network address which is self-assigned according to local area network address sharing assignment definition for the terminal under the local sharing account, and the fifth cloud gateway defines an assigned remote local area network address according to local area network address sharing assignment definition for the terminal under the remote sharing account;

and the fourth cloud gateway eliminates the allocated local area network address and the allocated remote local area network address according to the local area network address sharing allocation definition for the terminal which has a new request for allocating the address under the own local sharing account number, and allocates the new local area network address.

In this embodiment, the scenario of application of the method is the same as that of the previous embodiment, except that each cloud gateway is responsible for address allocation of the shared account under its own patch, and informs other cloud gateways of the process or result of its own address allocation, and the actions of each cloud gateway are corresponding to each other.

In an embodiment, the fourth cloud gateway establishes the same local area network address sharing allocation definition using the same gateway address as the fifth cloud gateway, and specifically includes:

Establishing an interconnection tunnel between a fourth virtual switch vswitch of the fourth cloud gateway and a fifth vswitch of the fifth cloud gateway;

the local area network address sharing allocation definition comprises a terminal available address range network, a subnet mask, a gateway address gateway and a release time release, and the local area network address is a class-C address.

In this embodiment, the detailed implementation steps of the method may be as shown in fig. 3-8 or fig. 9, where vswitch and vcpe are both components of a cloud gateway, and the device for allocating an address is on the cloud gateway. As shown in fig. 3, first, the definition of the lan address sharing allocation is performed in the cloud gateway, that is, the contents in the table homecpe dhcp pool in fig. 3. homecpe is a home CPE (Customer Premise Equipment), a wireless terminal access device for use in a home or small business environment, and vcpe in fig. 3 is a virtual cpe in a cloud gateway. In order to implement communication connection in the plurality of cloud gateways, an interconnection tunnel is also established through a vSwitch (Virtual Switch), and the access tunnel in fig. 3 is used to access the home terminal. In fig. 3, the network represents a usable address range of a terminal, the mask represents a subnet mask, the gateway represents a gateway address, the release represents a release time in s units, and the same network, mask, gateway and the same release are defined in the shared cloud gateway under the scenario that the cloud gateway allocates addresses for the terminals of the present patch.

In an embodiment, the fourth cloud gateway obtains a local sharing account number of a local area network address to be shared with the fifth cloud gateway using the same gateway address and a remote sharing account number of the fifth cloud gateway to be shared with the fourth cloud gateway using the same gateway address, and specifically includes:

Fourth vcpe establishes a local account for each physical lan accessed to itself, identifies each local account as the same local outer layer virtual lan pvlan and different local inner layer virtual lans cvlan, obtains a local shared account from the local accounts, and if there is a local non-shared account, allocates to use different gateway addresses for each local non-shared account;

Fourth vcpe obtains the remote shared account number and the remote pvlan and the remote cvlan thereof established by the fifth cloud gateway through the interconnection tunnel, and establishes a shared group to record the local shared account number and the local pvlan and the local cvlan thereof and the remote shared account number and the remote pvlan and the remote cvlan thereof.

In this embodiment, as shown in fig. 3, one account (account) in the homecpe account table provides DHCP service for a family, and uses QINQ to identify each account, and each account uses the same DHCP address pool and gateway address. In fig. 3, each account records its own pvlan and cvlan, pvlan outer VLAN (Virtual Local Area Network ), cvlan inner VLAN, outer VLAN distinguishes cloud gateway, inner VLAN distinguishes different families, if there is also a non-shared family, i.e. a normal family, the segments of the shared family and the normal family are different. As shown in fig. 4, a sharing group is created on vcpe where the accounts needing to implement the intercommunication need are located, the accounts needing to implement the family intercommunication all join the sharing group, the local accounts vcpe are identified by the identification accounts in the sharing group, the remote vcpe accounts are identified by remote, pvlan and cvlan are carried in the account attributes in the sharing group, and the process obtains the shared account information of the opposite end through the interconnection tunnel.

In an embodiment, the fourth cloud gateway obtains a local lan address which is already allocated for the terminal under the local shared account according to the lan address sharing allocation definition, and the fifth cloud gateway defines a remote lan address which is already allocated for the terminal under the remote shared account according to the lan address sharing allocation definition, which specifically includes:

A terminal under a fourth vcpe and a local shared account number completes local area network address allocation according to local area network address sharing allocation definition through a local dynamic Host Configuration Protocol (HCP) discover message, a HCP offer message, a HCP request message and a HCP ack message, records the allocated local area network address, copies the local HCP discover message, the HCP offer message, the HCP request message and the HCP ack message to a remote shared account number in a shared group, encapsulates a remote end pvlan and a remote end cvlan and then sends the remote end cvlan to a fifth vcpe through an interconnection tunnel;

Fourth vcpe receives remote dhcp discover message, dhcp offer message, dhcp request message and dhcp ack message sent by fifth vcpe and encapsulating local pvlan and local cvlan, and obtains fifth vcpe as a terminal under the remote shared account number, which defines the allocated remote local area network address according to the local area network address sharing allocation.

In this embodiment, as shown in fig. 5-8, after the found message of one home terminal reaches vcpe, vcpe copies the found message of the terminal to each remote type account in the shared group, encapsulates pvlan and cvlan of each remote account, and forwards the messages to the shared group of other vcpe for monitoring by using the interconnection tunnel, and simultaneously, the provided message of the dhcp and the subsequent request message of the dhcp and the confirmed message of the home terminal vcpe are copied to the remote account in this way. As in fig. 5, the left cloud gateway receives the dhcp discover message sent through its own access tunnel, which carries pvlan and cvlan, indicating that it is a terminal under ACCOUNT account number 1, the left side vcpe changes the message to pvlan2 and cvlan4 of ACCOUNT3 under encapsulation, pvlan and cvlan5 of ACCOUNT4, and sends it to the right side vcpe, so that the right side vcpe monitors the message, and the process of fig. 6-8 is similar. After the above steps are completed, the dhcp pool of the local site vcpe normally allocates an IP address to the terminal of the local site, marks the IP address as allocated, copies the complete dhcp flow message to other sites, marks the IP address as allocated in the shared group monitoring table of other sites, the remote site shared group notifies the local vcpe of the monitoring table change message, the dhcp pool mark IP of the local vcpe is used, the vcpe does not reallocate the corresponding IP to its own family members, and the dhcp table and the shared group monitoring table change.

In an embodiment, the fourth cloud gateway obtains a local lan address which is already allocated for the terminal under the local shared account according to the lan address sharing allocation definition, and the fifth cloud gateway defines a remote lan address which is already allocated for the terminal under the remote shared account according to the lan address sharing allocation definition, which specifically includes:

A fourth vcpe and a terminal under a local shared account number complete local area network address allocation according to local area network address sharing allocation definition through a local dynamic host configuration protocol dhcp discover message, a dhcp offer message, a dhcp request message and a dhcp ack message, record the allocated local area network address, copy the allocated local area network address to a far-end shared account number in a shared group, encapsulate a far-end pvlan and a far-end cvlan, and send to a fifth vcpe through an interconnection tunnel;

Fourth vcpe receives the remote lan address sent by fifth vcpe, encapsulates local pvlan and local cvlan, and records the remote lan address already allocated.

In this embodiment, another example is shown in fig. 9, where ue-IP indicates an IP address already allocated locally, and exposed-IP indicates an IP address already allocated at a remote end, and the process includes:

① . Vcpe of station 1 (left side) allocates 192.168.71.2 address to its own home terminal, and the address pool of the present station dhcp pool records the ip;

② . The vcpe of the site 1 monitors and judges that the flow of the 192.168.71.2 address allocated to the terminal is complete by the sharing group of the remote site 2 (right side), and determines that the ip is effectively allocated;

③ . Site 2 recognizes that the effectively allocated address 192.168.71.2, synchronizes to the dhcp pool address pool of vcpe of the site, and is not allocated subsequently;

④ . Vcpe of the station 2 allocates addresses 192.168.71.3 and 192.168.71.4 for the home terminals of the station, and the address pool of the dhcp pool of the station records the ip;

⑤ . Vcpe of site 2 allocates 192.168.71.3 and 192.168.71.4 addresses for the terminals, monitors and judges that the flow is complete for the shared group of the remote site 1, and determines that the ip is effectively allocated;

⑥ . Site 1 recognizes that addresses 192.168.71.3 and 192.168.71.4, which have been effectively allocated, synchronize to the dhcp pool address pool of the present site vcpe and are not subsequently allocated;

⑦ . Vcpe of the station 1 allocates an address 192.168.71.5 for the home terminal of the station again, and the address pool of the dhcp pool of the station records the ip;

⑧ . The vcpe of the site 1 monitors the flow of the 192.168.71.5 address allocated to the terminal by the sharing group of the remote site 2 and judges that the flow is complete, and determines that the ip is effectively allocated;

⑨ . Site 2 recognizes that the effectively allocated address 192.168.71.5, synchronizes to the dhcp pool address pool of vcpe of the present site, and is not allocated subsequently.

As shown in FIG. 10, the shared group in this embodiment may acquire the allocated address by monitoring the message, and the action flow of Shan Ceyun gateway includes receiving the DHCP message, locating the account, judging whether the account is in the shared group, if not, directly replying to the DHCP message, completing the address allocation, if so, replying to the DHCP message, and copying the message according to the remote account attribute of the shared group, judging whether the message attribute received by the interconnected tunnel is in the shared group, if not, discarding the message, if so, monitoring the DHCP message flow, judging whether the DHCP message flow is complete, if not, not marking the IP, marking the IP and synchronizing to the DHCP address pool, and if so, not allocating the marked IP to the terminal. In theory, after the VCPE allocates the local address, the opposite end VCPE may be directly told that the local end has allocated the address.

According to the embodiment, the DHCP flow of the account is copied to other accounts in the sharing group by controlling the copying mode and range of the DHCP message, and the effect of real-time synchronization of the use condition of the cloud gateway home address pool is achieved by the integrity monitoring and message pushing of the DHCP flow, so that the multi-account home terminal shares the same C-type address pool, multiple households are in the same broadcasting domain, the same gateway address is used, and home users in a home intercommunication scene keep the original use mode and internet surfing experience. Based on the concept of the sharing group, based on the information implementation of intercommunication IP and pvlan/cvlan among cloud gateways, the cloud gateway network among all places is opened, so that the local and remote IP allocation achieves the result of intercommunication sharing in different places based on the same address pool.
