With the development of the information age, network connection technology and TCP/IP protocol are widely popularized, and the network set top box gradually replaces the traditional set top box with better user experience. The use of network set-top boxes requires equipping the network set-top boxes with an IP network environment, and in recent years, IP networks have gradually transited from the mainstream IPv4 protocol to the IPv6, and from the aspect of network protocol design, the network set-top boxes are more likely to be required to preferentially use the IPv6 to connect servers.

When the existing dual-stack network connection method is abnormal in the IPv6 environment, the IPv4 connection is automatically switched, but the subsequent connection still tries the IPv6 connection, and the dual-stack network connection method always tries the IPv4 and the IPv6 connection according to a fixed sequence consumes a large amount of time for each connection.

Detailed Description
In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
As shown in fig. 1, fig. 1 is a flowchart of a network dual stack connection method according to an embodiment of the present invention.
The network dual-stack connection method in the embodiment comprises the following steps:
s101, judging whether the priority connection weight of the IPv4 and the priority connection weight of the IPv6 in the dual-stack network environment are larger than or equal to a preset weight value, wherein the preset weight value is set by considering the following steps: if the stability of the local network is high, or the priority set by the user is required to be considered preferentially, but not the network connection efficiency, X can be set to be a large value, and the network is connected according to the priority preset by the user in most cases; if the stability of the network is low or the network connection efficiency is prioritized, instead of the priority set by the user, X may be set to a small value, and a network protocol with higher efficiency is selected according to the actual connection success rate in most cases.

S103, selecting IPv4 to attempt connection, if the connection is successful, increasing a set value for the priority connection weight of IPv4, and if the connection is failed, selecting IPv6 to attempt connection.
S104, according to the judgment result of the step S101, if the priority connection weight of the IPv6 is greater than or equal to the preset weight value, executing a step S105.
And S105, selecting IPv6 to attempt connection, if the connection is successful, increasing a set value for the priority connection weight of IPv6, and if the connection is failed, selecting IPv4 to attempt connection.
The technical scheme of the embodiment of the invention solves the problem that when the existing double-stack network connection method faces a double-stack network environment, the IPv4 and the IPv6 are always tried to be connected according to a fixed sequence, so that when a certain network connection is abnormal for a long time, each connection consumes a large amount of time, and the user experience is influenced. When one of the IPv4 and the IPv6 network connection is abnormal under the dual-stack network, the network dual-stack connection scheme provided by the invention is adopted, the variable (the priority connection weight of the IPv4 and the priority connection weight of the IPv 6) is added to judge the abnormal IP network, and the normal IP network is preferentially selected in the subsequent connection, so that the time consumption of connection failure is avoided, and the network connection speed is improved.
Example two
As shown in fig. 2, fig. 2 is a flowchart of a network dual stack connection method according to a second embodiment of the present invention.
The network dual-stack connection method in the embodiment specifically comprises the following steps:
s201, determining whether the priority connection weight of IPv4 and the priority connection weight of IPv6 in the dual stack network environment are greater than or equal to a preset weight value (X in fig. 2), where the preset weight value X is set in consideration of the following: if the stability of the local network is high, or the priority set by the user is required to be considered preferentially, but not the network connection efficiency, X can be set to be a large value, and the network is connected according to the priority preset by the user in most cases; if the stability of the network is low or the network connection efficiency is prioritized, instead of the priority set by the user, X may be set to a small value, and a network protocol with higher efficiency is selected according to the actual connection success rate in most cases.
S202, according to the judgment result of the step S201, if the priority connection weight of the IPv4 is greater than or equal to the preset weight value, the step S203 is executed.
S203, selecting IPv4 to try connection, if the connection is successful, increasing a set value for the priority connection weight of IPv4, and if the connection is failed, selecting IPv6 to try connection.
And S204, according to the judgment result in the step S201, if the priority connection weight of the IPv6 is greater than or equal to the preset weight value, executing a step S205.
S205, selecting IPv6 to try connection, if the connection is successful, increasing a set value for the priority connection weight of IPv6, and if the connection is failed, selecting IPv4 to try connection.
Illustratively, in this embodiment, the network dual-stack connection method further includes the following steps:
s206, according to the judgment result of the step S201, if the priority connection weight of the IPv4 and the priority connection weight of the IPv6 are smaller than the preset weight value, executing a step S203 when the connection priority set by the user is that the IPv4 is preferentially selected to attempt connection; when the connection priority set by the user is to preferentially select IPv6 for attempting connection, step S205 is performed.
For example, in this embodiment, the increasing of the priority connection weight setting value of IPv4 in step S203 specifically includes: the priority connection weight of IPv4 is increased by 1, and it should be noted that the setting value is not limited to 1, and its size may be specifically determined according to the actual application.
For example, in this embodiment, the increasing of the priority connection weight by the IPv6 in step S205 specifically includes: the priority connection weight of IPv6 is increased by 1, and it should be noted that the setting value is not limited to 1, and its size may be specifically determined according to the actual application.
For example, in this embodiment, if the connection fails in step S203, selecting IPv6 to attempt connection, specifically including: if the connection fails, the priority connection weight of IPv4 is set to zero, IPv6 is selected to attempt connection, it should be noted that "if the connection fails, the priority connection weight of IPv4 is set to zero" is only a preferable mode, as long as the problems in the prior art can be solved, the scheme without being set to zero is also applicable to the present invention, for example, the connection weight of IPv4 may be subtracted by 1 (also not limited to 1) in case of connection failure, and this mode can obtain a more optimized network priority, but needs more connection times.
For example, in this embodiment, if the connection fails in step S205, selecting IPv4 to attempt connection includes: if the connection fails, the priority connection weight of IPv6 is set to zero, IPv4 is selected to attempt connection, it should be noted that "if the connection fails, the priority connection weight of IPv6 is set to zero" is only a preferable mode, as long as the problems in the prior art can be solved, the scheme without being set to zero is also applicable to the present invention, for example, the connection weight of IPv6 may be subtracted by 1 (also not limited to 1) in case of connection failure, and this mode can obtain a more optimized network priority, but needs more connection times.
Specifically, when the scheme of this embodiment is applied to a network set-top box, the set-top box uses a domain name address to connect a server, and firstly needs DNS domain name resolution to obtain an IP address, and if the domain name corresponds to a plurality of servers, the set-top box will obtain a plurality of IP addresses, and determine whether there are IPv4 and IPv6 addresses at the same time. If the IPv4 and IPv6 addresses exist at the same time, the network set top box belongs to a dual-stack network environment, and the network set top box uses the scheme of this embodiment: in an initial state, the priority connection weight of the IPv4 and the priority connection weight of the IPv6 are both zero, the IPv4 is preferentially selected to attempt connection, or the IPv6 is preferentially selected to attempt connection, which preference is initially set by a user is used for determining, 1 is added to the corresponding IP protocol priority connection weight after connection is successful each time, and the priority connection weight of the IP protocol is cleared when connection is failed; and when the weight is greater than the preset weight value, the IP protocol is preferentially selected for connection, and the priority of protocol connection does not depend on the setting of the user any more. For example: the current environment does not have an IPv6 connection environment, but a user sets that the set-top box preferentially uses IPv6 for connection, the set-top box preferentially tries to connect with an IPv6 address and fails to try to connect with IPv4, the preferential connection weight of IPv4 rises after connection succeeds, when the preferential connection weight of IPv4 rises to a preset weight value, the current environment is considered to not have an IPv6 environment, the network set-top box preferentially uses IPv4 for connection in subsequent network connection, the IPv6 connection cannot be tried, time consumed by connection failure is avoided, and network connection speed is improved.
The invention solves the problem that when the existing dual-stack network connection method faces the dual-stack network environment, the IPv4 and the IPv6 are always tried to be connected according to a fixed sequence, so that when a certain network connection is abnormal for a long time, each connection consumes a large amount of time, and the user experience is influenced. When one of the IPv4 and the IPv6 network connection is abnormal under the dual-stack network, the network dual-stack connection scheme provided by the invention is adopted, the variable (the priority connection weight of the IPv4 and the priority connection weight of the IPv 6) is added to judge the abnormal IP network, and the normal IP network is preferentially selected in the subsequent connection, so that the time consumption of connection failure is avoided, and the network connection speed is improved.
EXAMPLE III
As shown in fig. 3, fig. 3 is a block diagram of a network dual-stack connection device 300 according to a third embodiment of the present invention.
The network dual-stack connection apparatus 300 in this embodiment includes:
a priority connection weight determining unit 301, configured to determine whether a priority connection weight of IPv4 and a priority connection weight of IPv6 in the dual stack network environment are greater than or equal to a preset weight value, if the determination result is that the priority connection weight of IPv4 is greater than or equal to the preset weight value, the IPv4 connection selecting unit 302 is started, and if the determination result is that the priority connection weight of IPv6 is greater than or equal to the preset weight value, the IPv6 connection selecting unit 303 is started. Wherein, the setting of the preset weight value is considered as follows: if the stability of the local network is high, or the priority set by the user is required to be considered preferentially, but not the network connection efficiency, X can be set to be a large value, and the network is connected according to the priority preset by the user in most cases; if the network stability is low or the network connection efficiency is prioritized, but the user-set priority is not, X can be set to a small value, and a network protocol with higher efficiency is selected according to the actual connection success rate in most cases
An IPv4 connection selecting unit 302, configured to select IPv4 to attempt connection, where if the connection is successful, the priority connection weight of IPv4 is increased by a set value, and if the connection is failed, the IPv6 connection selecting unit 303 selects IPv6 to attempt connection.
An IPv6 connection selecting unit 303, configured to select IPv6 to attempt connection, where if the connection is successful, the priority connection weight of IPv6 is increased by a set value, and if the connection is failed, the IPv4 connection selecting unit 302 selects IPv4 to attempt connection.
The invention solves the problem that when the existing dual-stack network connection method faces the dual-stack network environment, the IPv4 and the IPv6 are always tried to be connected according to a fixed sequence, so that when a certain network connection is abnormal for a long time, each connection consumes a large amount of time, and the user experience is influenced. When one of the IPv4 and the IPv6 network connection is abnormal under the dual-stack network, the network dual-stack connection scheme provided by the invention is adopted, the variable (the priority connection weight of the IPv4 and the priority connection weight of the IPv 6) is added to judge the abnormal IP network, and the normal IP network is preferentially selected in the subsequent connection, so that the time consumption of connection failure is avoided, and the network connection speed is improved.
Example four
As shown in fig. 4, fig. 4 is a block diagram of a network dual-stack connection device 400 according to a fourth embodiment of the present invention.
The network dual-stack connection device 400 in this embodiment specifically includes:
a priority connection weight determining unit 401, configured to determine whether a priority connection weight of IPv4 and a priority connection weight of IPv6 in the dual stack network environment are greater than or equal to a preset weight value, if the determination result is that the priority connection weight of IPv4 is greater than or equal to the preset weight value, the IPv4 connection selecting unit 402 is started, and if the determination result is that the priority connection weight of IPv6 is greater than or equal to the preset weight value, the IPv6 connection selecting unit 403 is started. Wherein, the setting of the preset weight value is considered as follows: if the stability of the local network is high, or the priority set by the user is required to be considered preferentially, but not the network connection efficiency, X can be set to be a large value, and the network is connected according to the priority preset by the user in most cases; if the stability of the network is low or the network connection efficiency is prioritized, instead of the priority set by the user, X may be set to a small value, and a network protocol with higher efficiency is selected according to the actual connection success rate in most cases.
An IPv4 connection selecting unit 402, configured to select IPv4 to attempt connection, if the connection is successful, the priority connection weight of IPv4 is increased by a set value, and if the connection is failed, the IPv6 connection selecting unit 403 selects IPv6 to attempt connection.
An IPv6 connection selecting unit 403, configured to select IPv6 for attempting connection, where if the connection is successful, the priority connection weight of IPv6 is increased by a set value, and if the connection is failed, the IPv4 connection selecting unit 402 selects IPv4 for attempting connection.
Illustratively, in this embodiment, the network dual-stack connection apparatus 400 further includes: a connection priority setting unit 404; the connection priority setting unit 404 is used for setting connection priorities of IPv4 and IPv6 for a user; when the priority connection weight judgment unit 401 determines that the priority connection weight of the IPv4 and the priority connection weight of the IPv6 are smaller than the preset weight value, the IPv4 connection selection unit 402 or the IPv6 connection selection unit 403 is determined to be started according to the connection priority set by the user through the connection priority setting unit 404.
Illustratively, in this embodiment, the setting value for increasing the priority connection weight of IPv4 specifically includes: the priority connection weight of IPv4 is increased by 1, and it should be noted that the setting value is not limited to 1, and its size may be specifically determined according to the actual application. The setting value for increasing the priority connection weight of the IPv6 specifically includes: the priority connection weight of IPv6 is increased by 1, and it should be noted that the setting value is not limited to 1, and its size may be specifically determined according to the actual application.
For example, in this embodiment, if the connection fails, the IPv6 connection selecting unit 403 selects IPv6 to attempt connection, which specifically includes: if the connection fails, the priority connection weight of IPv4 is set to zero, and the IPv6 connection selecting unit 403 selects IPv6 to attempt connection. It should be noted that "if the connection fails, the priority connection weight of IPv4 is reset to zero" is only a preferable mode, and a scheme not reset to zero is also applicable to the present invention as long as the problems in the prior art can be solved, and for example, in the case of a connection failure, the connection weight of IPv4 may be subtracted by 1 (similarly, not limited to 1), which can obtain a more optimized network priority, but requires a larger number of connections. If the connection fails, the IPv4 connection selecting unit 402 selects IPv4 to attempt connection, which specifically includes: if the connection fails, the priority connection weight of IPv6 is set to zero, and the IPv4 connection selecting unit 402 selects IPv4 to attempt connection. It should be noted that "if the connection fails, the priority connection weight of IPv6 is reset to zero" is only a preferable mode, and a scheme not reset to zero is also applicable to the present invention as long as the problems in the prior art can be solved, and for example, in the case of a connection failure, the connection weight of IPv6 may be subtracted by 1 (similarly, not limited to 1), which can obtain a more optimized network priority, but requires a larger number of connections.
When the scheme of the embodiment is applied to a network set top box, the set top box uses a domain name address to connect a server, firstly, DNS domain name resolution is needed to obtain IP addresses, if the domain name corresponds to a plurality of servers, the set top box can obtain a plurality of IP addresses, and whether IPv4 and IPv6 addresses exist simultaneously or not is judged. If the IPv4 and IPv6 addresses exist at the same time, the network set top box belongs to a dual-stack network environment, and the network set top box uses the scheme of this embodiment: in an initial state, the priority connection weight of the IPv4 and the priority connection weight of the IPv6 are both zero, the IPv4 is preferentially selected to attempt connection, or the IPv6 is preferentially selected to attempt connection, which preference is initially set by a user is used for determining, 1 is added to the corresponding IP protocol priority connection weight after connection is successful each time, and the priority connection weight of the IP protocol is cleared when connection is failed; and when the weight is greater than the preset weight value, the IP protocol is preferentially selected for connection, and the priority of protocol connection does not depend on the setting of the user any more. For example: the current environment does not have an IPv6 connection environment, but a user sets that the set-top box preferentially uses IPv6 for connection, the set-top box preferentially tries to connect with an IPv6 address and fails to try to connect with IPv4, the preferential connection weight of IPv4 rises after connection succeeds, when the preferential connection weight of IPv4 rises to a preset weight value, the current environment is considered to not have an IPv6 environment, the network set-top box preferentially uses IPv4 for connection in subsequent network connection, the IPv6 connection cannot be tried, time consumed by connection failure is avoided, and network connection speed is improved.
The technical scheme of the embodiment of the invention solves the problem that when the existing double-stack network connection method faces a double-stack network environment, the IPv4 and the IPv6 are always tried to be connected according to a fixed sequence, so that when a certain network connection is abnormal for a long time, each connection consumes a large amount of time, and the user experience is influenced. When one of the IPv4 and the IPv6 network connection is abnormal under the dual-stack network, the network dual-stack connection scheme provided by the invention is adopted, the variable (the priority connection weight of the IPv4 and the priority connection weight of the IPv 6) is added to judge the abnormal IP network, and the normal IP network is preferentially selected in the subsequent connection, so that the time consumption of connection failure is avoided, and the network connection speed is improved.
EXAMPLE five
The embodiment of the invention further provides a network set top box, which comprises the double-stack network connecting device in any one of the third embodiment and the fourth embodiment.
When the network set-top box works, the domain name address is used for connecting the servers, firstly, DNS domain name resolution is carried out to obtain IP addresses, if the domain name corresponds to a plurality of servers, the network set-top box can obtain a plurality of IP addresses, and whether IPv4 and IPv6 addresses exist simultaneously or not is judged. If there are IPv4 and IPv6 addresses at the same time, the network device belongs to a dual-stack network environment, and for example, in this embodiment, the network set-top box uses the scheme of the fourth embodiment as an example: in an initial state, the priority connection weight of the IPv4 and the priority connection weight of the IPv6 are both zero, and the IPv4 is preferentially selected to attempt connection or the IPv6 is preferentially selected to attempt connection, which preference is initially set by a user is determined, the priority connection weight of the corresponding IP protocol is increased by 1 after connection is successful each time, and the priority connection weight of the IP protocol is cleared when connection is failed, but not limited thereto, for example, the priority connection weight of the protocol may be subtracted by 1 (but not limited to 1) in the case of connection failure, which can obtain a more optimized network priority but requires more connection times; when the weight is greater than a preset weight value, the IP protocol is preferentially selected for connection, the priority of protocol connection does not depend on the setting of a user any more, wherein the preset weight value is set by considering the following steps: if the stability of the local network is high, or the priority set by the user is required to be considered preferentially, but not the network connection efficiency, X can be set to be a large value, and the network is connected according to the priority preset by the user in most cases; if the stability of the network is low or the network connection efficiency is prioritized, instead of the priority set by the user, X may be set to a small value, and a network protocol with higher efficiency is selected according to the actual connection success rate in most cases. For example: the current environment does not have an IPv6 connection environment, but a user sets that the set-top box preferentially uses IPv6 for connection, the set-top box preferentially tries to connect with an IPv6 address and fails to try to connect with IPv4, the preferential connection weight of IPv4 rises after connection succeeds, when the preferential connection weight of IPv4 rises to a preset weight value, the current environment is considered to not have an IPv6 environment, the network set-top box preferentially uses IPv4 for connection in subsequent network connection, the IPv6 connection cannot be tried, time consumed by connection failure is avoided, and network connection speed is improved.
The network set-top box provided by the embodiment of the invention solves the problem that when the existing set-top box faces a dual-stack network environment, the connection of IPv4 and IPv6 is always tried according to a fixed sequence, so that when a certain network connection is abnormal for a long time, each connection consumes a large amount of time, and the user experience is influenced. When the invention is adopted to judge the abnormal IP network by increasing the variables (the priority connection weight of IPv4 and the priority connection weight of IPv 6) when one of the IPv4 and IPv6 network connection is abnormal under the double-stack network, the normal IP network is preferentially selected in the subsequent connection, the time consumption of connection failure is avoided, and the network connection speed is improved.
