Detection, CM when Cable detection means detects upper level link abnormal signal, manually reached the standard grade, wasted time and energy again, or even meeting
Influence CM function.
Based on this, the embodiments of the invention provide CMTS system upper level link guard methods and device, below by implementation
Example is described.
Embodiment 1
Referring to Fig. 1, the annexation of CMTS system upper level link, the CMTS systems include under introducing first：Main CMTS
(i.e. CMTS1), standby CMTS (i.e. CMTS2), Cable line switchers (i.e. Cable Switch), upper level link, second line of a couplet link
And CM, CM are connected by second line of a couplet link with Cable line switchers, main CMTS and standby CMTS with Cable line switchers
It is connected, also, main CMTS and standby CMTS pass through upper level link and Cable networks (the Netwrok provider i.e. in figure)
It is connected.
Referring to Fig. 2, the CMTS system upper level link guard method that the present embodiment proposes is applied to link detecting system, specifically
Comprise the following steps：
Step S101：The status signal of upper level link is detected, wherein, upper level link is used to connect main CMTS and Cable nets
Network, i.e., can be using the preferable CMTS of hardware configuration as main CMTS, so as to drive CM preferably to carry out under normal use scene
Work.Main CMTS is connected by upper level link with Cable networks, to obtain Internet resources etc..Need exist for illustrating,
The link detecting system of status signal for detecting upper level link is typically located at the software systems in main CMTS.Detection
Cycle length according to circumstances can flexibly be set.
Step S102：When status signal occurs abnormal, control Cable line switchers send conversion signal, work as detection
When occurring abnormal to the status signal of upper level link, control Cable line switchers send conversion signal, it is necessary to illustrate
It is that conversion signal is usually RF signals, RF signals are also known as radiofrequency signal, and it represents the electromagnetic frequency that can be radiated space,
For frequency range between 300KHz~300GHz, RF signals are a kind of high-frequency ac change electromagnetic waves, long transmission distance, transmit letter
It is number reliable and stable.
Step S103：According to conversion signal, main CMTS and CM connection is converted into standby CMTS and CM connection.Having
Body implement when, directly triggered by conversion signal Cable line switchers original main CMTS and CM connection are converted into it is standby
CMTS and CM connection.
Referring to Fig. 3, the status signal of upper level link is detected in step S101, wherein, upper level link is used to connect main CMTS
The detection of following situations, i.e. CMTS first line of a couplet port is specifically included with the step of Cable networks：
Step S10101：Whether the upper level link for detecting main CMTS disconnects, i.e., the connection between main CMTS and Cable networks
Whether disconnect.
Step S10102：When detecting that upper level link disconnects, the up channel parameter of upper level link and descending letter are preserved
Road parameter, i.e., when the connection between main CMTS and Cable networks is already off, first to preserve the up channel parameter of upper level link
And down channel parameters, used when recovering again so as to upper level link.
Step S10103：Up channel and down channel are closed, is keeping up channel parameter and down channel parameters
Afterwards, up channel and down channel are closed.
Step S10104：After descending channel off, status signal is arranged to abnormal.Detect that down channel is closed
Afterwards, status signal is arranged to abnormal, to remind Cable that line switcher is changed in time.
Referring to Fig. 4, the status signal of upper level link is detected in step S101, wherein, upper level link is used to connect main CMTS
The step of with Cable networks also, specifically includes following situations, i.e. PING bags detect：
Step S10111：The first line of a couplet for detecting IPv4 and IPv6, IPv4 or the IPv6 configured specifies the IP address of network element,
Needing exist for illustrating, IPv4 is Internet protocol (Internet Protocol, IP) fourth edition, and first
It is individual to be widely used, form the basic agreement of Internet technology now.IPv6 is Internet Protocol Version 6
Abbreviation, wherein Internet Protocol are translated into " Internet protocol ".IPv6 be IETF (Internet Engineering Task group,
Internet Engineering Task Force) that designs is used to substitute the IP of future generation of current edition IP agreement (IPv4)
Agreement.Because the problem of IPv4 maximums is that network address resources are limited, the application and development of internet are seriously constrained.IPv6
Use, can not only solve the problems, such as network address resources quantity, and solve a variety of access devices and be connected into internet
Obstacle.In the present embodiment, described IP includes IPv4 and IPv6, IPv4 or IPv6.
Step S10112：When detecting that upper level link is obstructed corresponding to IP address, and, obstructed number, which is equal to, to be preset
It is maximum when attempting the frequency of failure, close the up channel and down channel of upper level link.For example, when to an IP in IPv6
When corresponding upper level link carries out path detection, it is found that obstructed number reaches the maximum frequency of failure of attempting set in advance and (needed
To be illustrated, the maximum frequency of failure of attempting set in advance is usually an empirical value) when, that is, judge the upper level link
Really it is obstructed, now, closes the up channel and down channel of upper level link.
Step S10113：After descending channel off, status signal is arranged to abnormal.When detect down channel close
Afterwards, status signal is arranged to abnormal, to remind Cable that line switcher is changed in time.
In addition, in order to recover the use of upper level link as early as possible, CMTS system upper level link guard methods also include：
(1) whether detection upper level link connects again, that is, corresponds to the detection process of CMTS first line of a couplet port, detects upper level link
Whether connect again.
(2) when detecting upper level link connection, up channel and down channel is opened, that is, passes through the channel of above-mentioned preservation
Parameter reopens up channel and down channel.
(3) status signal is arranged to upstate.Upper level link is arranged to upstate, so that main CMTS recovers
To the connection with upper level link.
In addition, in order to recover the use of upper level link as early as possible, CMTS system upper level link guard methods also include：
(1) whether upper level link corresponding to detection IP address is path, that is, PING bag detection process is corresponded to, come with detecting IP
Whether upper level link corresponding to location connects again.
(2) when being consecutively detected number of the upper level link for path more than recovery number set in advance, open up
Channel and down channel are, it is necessary to illustrate, and in order to ensure the patency of upper level link, upper level link needs continuously examining
Ensure the number of path during survey, recovery number set in advance is an empirical value here, the big I root of concrete numerical value
Flexibly set according to usage scenario.
(3) status signal is arranged to upstate.Upper level link is arranged to upstate, so that main CMTS recovers
To the connection with upper level link.
In summary, the CMTS system upper level link guard methods that the present embodiment provides include：Firstly the need of the detection first line of a couplet
For the status signal of link, it is necessary to illustrate, upper level link is the communication chain for connecting main CMTS and Cable networks
Road, next to that when detecting that above-mentioned status signal occurs abnormal, control Cable line switchers send conversion signal, also,
According to conversion signal, main CMTS and CM connection is converted into standby CMTS and CM connection, makes CM by connecting with standby CMTS
Access Cable networks after connecing, so as to effectively prevent because the appearance such as main CMTS or upper level link have an impact to CM extremely
Situation occur, further improve the operational efficiency of system, it is convenient and swift.
