Description
Technical Field
The present invention relates to the field of computers, and in particular, to a method and an apparatus for controlling aging of a time domain session, a storage medium, and an electronic apparatus.
Background
The Security Transport Layer Protocol (TLS) handshake is a link with very high performance overhead, and generally, when a server switches from a hypertext Transfer Protocol (HTTP) to a network Protocol (HTTP), the performance may be reduced by more than ten times. In order to effectively reduce this performance overhead, the TLS protocol develops a Session multiplexing mechanism. That is, the Session context is cached at the server of the TLS for a period of time, and when the symmetric encryption channel can be multiplexed next time, the negotiated symmetric encryption channel can be directly searched and selected for communication without going through the most performance-consuming asymmetric handshake part.
Then the cached Session must have an aging algorithm to ensure that the internally stored Session does not grow all the time, thereby exploding the memory. The index used by the client query is called Session identification Session ID. However, in OpenSSL, an open condom level protocol, or in Nginx, the Session ages completely in time.
That is, the majority of TLS sessions are completely time-out of multiplex throughout the world. At time, the Session will expire regardless of its frequency of use, and a re-handshake is periodically triggered. Namely, the problem that the service experience is influenced by the centralized aging of the online TLS Session in the prior art exists.
In view of the above problems, no effective solution has been proposed.

Fig. 2 is a flowchart illustrating a method for controlling aging of a time domain session according to an embodiment of the present invention, as shown in fig. 2, the method includes the following steps:
step S202, determining the initial aging time length of the session, wherein the initial aging time length is set by a time aggregator, and the time aggregator is a global variable taking time as a unit;
step S204, when the residual time length of the initial aging time length is within a first preset time range, determining the multiplexing condition of the session, wherein the residual time length is a time period before the session is aged;
and step S206, controlling the aging of the session according to the multiplexing condition of the session.
Through the steps, the time concentrator is adopted to determine the initial aging time length of the session, when the remaining time length of the initial aging time length is within a first preset time range, the multiplexing situation of the session is determined, and the aging of the session is controlled based on the multiplexing situation of the session. The purpose of determining the aging time of the session according to the using frequency of the session is achieved, so that the effect of effectively setting the aging time of the session is achieved, and the technical problem that the setting of the aging time of the session influences service experience in the related technology is solved.
It should be noted that, in this embodiment, the aging time of the session is scattered in the time domain. The scattering mode is a global deviation representing the time speed, and a decision system for delaying aging close to the aging time.
First, when a large number of TLS requests arrive, it is the conventional practice to set an aging time point with the same expiration time for each newly generated Session, and then to age the Session at that time point. This causes a problem of concentrated aging. This example sets a global variable, called time aggregator, in seconds, to increment by 1 each time a Session is newly generated.
Optionally, the initial aging length of time for the session is determined by a time aggregator by:
1) and determining the time point when the session is generated and the value of the time encryptor, namely adding 1 to the value of the global variable when the session is generated and determining the value of the time encryptor when the session is generated.
2) Determining the aging time length configured for the Session, that is, when a TLS request arrives, the user may directly set an aging time point of an expiration time, which may be 10s, for the newly generated Session through the configuration file of Nginx;
3) the value of the time point, the time aggregator and the sum of the aging time lengths configured for the session are determined as the initial aging time length. The time point is the current time point, and the time stamp time point of the system can be directly obtained. And the time of Session aging is the current time point + the configured aging time length + the time aggregator. Such a setting may achieve that at most one Session will age in one second. Since Nginx is multiprocess, but multiple processes share a Session Cache, each process maintains a time cipher, so that the number of sessions equivalent to Worker, which has Nginx at most, per second is aged. The idea is that the larger the number of Worker number turns on at Nginx, the larger the expected on-line traffic, the faster the corresponding Session creation speed will be, so the larger the number of Session instances allowed to age per second will be.
Optionally, when the remaining time length of the initial aging time length is within the first preset time range, determining the reuse condition of the session by the following method:
1) setting a counter in a second preset time range, wherein the time length of the second preset time range is less than or equal to the initial aging time length, and the time length of the first preset time range is less than the initial aging time length; in this embodiment, when the aging time of a Session is about to arrive, it is used to decide whether to age according to the aging time set before. It is necessary to distinguish between different aging times for sessions with a high and low frequency of use. Specifically, if a Session is expected to continue to be used in the near future, the Session aging time is postponed. If a Session is expected not to continue to be used for a considerable period of time, the aging continues as intended by the intended aging time.
2) Calculating the number of times the session is multiplexed by using a counter; each time the Session is queried and reused, the counter is increased;
3) and judging whether the session is multiplexed within a first preset time range. It may be within the last 10s of Session-fast aging.
Optionally, the aging of the session is controlled by: postponing the aging time of the session under the condition that the session is multiplexed within a first preset time range; the deferred aging time may determine a product of the number of times the session is multiplexed and a time length of a second preset time range as the deferred aging time of the session. The method specifically comprises the following steps: if there is any multiplexing of the Session, the aging time deferral counter number for the Session is multiplied by a constant fixed unit of seconds (e.g., 10). That is, when a Session is in the last ten seconds, if multiplexing occurs, the number of multiplexing before 10s is postponed. After the aging is postponed, the counter of the number of multiplexing is cleared. And each Session has a maximum accumulated delay, which may be three times the configured aging time.
And in the case that the conversation is not multiplexed within a first preset time range, aging the conversation according to the initial aging time.
Optionally, after deferring the aging time of the session, the counter is cleared to facilitate the next count.
Optionally, the time to defer is limited, and beyond the maximum aging time, forced aging of the session will occur. The method specifically comprises the following steps:
1) determining a number of times a session is deferred for aging; the number of times is counted using a counter.
2) Calculating the time length of each time the session is delayed from aging;
3) calculating the accumulated delay time of the delayed aging of the conversation according to the times and the time length of each time of the delayed aging;
4) and when the accumulated deferral time is greater than a preset time length, forcing the aging session, wherein the preset time length is a multiple of the initial aging time length. The expiration may be marked directly rather than calculating an expiration time as in previous expiration calculations. Those marked expired are automatically aged by Nginx. Sessions of different importance can be distinguished significantly in their aging time, which is the result of a prediction of the frequency of use of future sessions.
As can be seen from the above, the multiplexing efficiency of TLS Session is significantly improved. Important sessions cannot be easily aged, and traffic congestion caused by intensive aging cannot be caused by traffic emergency.
The invention will now be described in detail with reference to a preferred embodiment:
in the related art, when TLS traffic is bursty, for example, a certain product organizes an activity, the traffic suddenly increases. At this time a large number of TLS sessions are created and these newly created TLS sessions are almost the same time that is aged. Traffic may be stuck at the beginning of the activity because the server is carrying a tremendous TLS handshake pressure, but after the early entry phase is spent, the traffic is smoother due to the reuse of TLS sessions. However, due to the existence of timing aging, the sessions will be aged at the same time point in a large amount, which means that the server of the service will enter the first stuck period. And at this time, the normal activities are still in progress, which greatly affects the quality of the business activities. The Session aging time on the line is in a knife-cut manner according to the practice of Nginx and OpenSSL. The same aging time is used for all sessions. But obviously the frequency of use of different sessions is completely different. The aging time for the on-line configuration is generally not too long because of security concerns, but not too short, otherwise it is not as different as without the TLS Session mechanism. It is very difficult to find an intermediate value of the aging time in all clients that use different frequencies of sessions. This value is usually not optimal.
The problem to be solved by this embodiment is the aging time of the above middle on-line TLS Session. The method has two main purposes, namely solving the problem that the service experience is influenced by centralized aging and solving the problem that different aging times of different sessions are determined according to the Session importance degree.
The core of this embodiment is that the aging time is broken up in the time domain by the Nginx program. This break-up is by a global time rate shift, and by a deferred aging decision-making system that approximates the aging time.
First, when a large number of TLS requests arrive, it is the conventional practice to set an aging time point with the same expiration time for each newly generated Session, and then to age at that time point. This causes a problem of concentrated aging. The device sets a global variable, and adds 1 every time a Session is newly generated, wherein the global variable is called a time aggregator and has the unit of second.
The setting of the aging time of the current Session is not set solely according to the expiration time but is set simultaneously according to the sum of the expiration time and this time aggregator. That is, the time for Session aging is current time + configured aging time length + time aggregator. This arrangement makes it possible to have at most one Session aged in one second. Since Nginx is multiprocess, but multiple processes share a Session Cache, each process maintains a time cipher, so that the number of sessions equivalent to Worker, which has Nginx at most, per second is aged. The idea is that the larger the number of Worker number turns on at Nginx, the larger the expected on-line traffic, the faster the corresponding Session creation speed will be, so the larger the number of Session instances allowed to age per second will be.
The contents of the second core are used to decide whether to age according to the previously set aging time when the aging time of a Session is about to arrive. The aim is to distinguish between different aging times for sessions with high and low frequency of use, and specifically to postpone the aging time for a Session if it is expected to continue to be used in the near future. If a Session is expected not to continue to be used for a considerable period of time, the aging continues as intended by the intended aging time.
The method for judging whether to postpone aging is to maintain a counter within the time range that the Session is not aged, and the counter is increased when the Session is repeatedly inquired each time. Within the last 10s of the Session's immediate aging, if there is any multiplexing of the Session, the Session's aging time delay counter number is multiplied by a constant fixed unit of seconds (this value is 10 in our use). That is, when a Session is in the last ten seconds, if multiplexing occurs, the number of multiplexing before 10s is postponed. After the aging is postponed, the counter of the number of multiplexing is cleared. And each Session has a maximum accumulated delay that exceeds three times the configured aging time, and if the Session has not been aged, aging is not postponed. Thus the Session is forced to age regardless of frequency.
The key point in this is two points, one is the last 10s decision and one is the cumulative number of multiplexes of preambles. The last 10s decision means that short term high frequency TLS connections can be circumvented. If a TLS connection is being reused for the next five minutes at the time of creation, the cumulative number of reuses will be large, and if the deferred aging is determined only according to the cumulative number of reuses, an incorrect aging decision will result, since the connection is no longer in use. The last 10s decisions can solve the TLS Session multiplexing situation with dense creation period, which is very high in practical applications.
The time for postponing aging is defined as the cumulative number of multiplexes multiplied by 10 seconds and cannot be larger than the maximum aging time, and the design can obviously distinguish the aging time of sessions with different degrees of importance, namely a result of prediction of the use frequency of the future sessions.
Through the preferred embodiment, the following technical effects can be obtained: the multiplexing efficiency of the TLS Session is obviously improved. Important sessions cannot be easily aged, and traffic congestion caused by intensive aging cannot be caused by traffic emergency.
It should be noted that the main body for executing the above steps may be the terminal shown in fig. 1, but is not limited thereto.
An embodiment of the present invention further provides a device for controlling aging of a time domain session, and fig. 3 is a schematic structural diagram of the device for controlling aging of a time domain session, provided in the embodiment of the present invention, as shown in fig. 3, the device includes:
a first determining module 32, configured to determine an initial aging time length of the session, where the initial aging time length is set by a time aggregator, and the time aggregator is a global variable in units of time;

and the control module 36 is used for controlling the aging of the session according to the multiplexing condition of the session.
Through the steps, the time concentrator is adopted to determine the initial aging time length of the session, when the remaining time length of the initial aging time length is within a first preset time range, the multiplexing situation of the session is determined, and the aging of the session is controlled based on the multiplexing situation of the session. The purpose of determining the aging time of the session according to the using frequency of the session is achieved, so that the effect of effectively setting the aging time of the session is achieved, and the technical problem that the setting of the aging time of the session influences service experience in the related technology is solved.
It should be noted that, in this embodiment, the aging time of the session is scattered in the time domain. The scattering mode is a global deviation representing the time speed, and a decision system for delaying aging close to the aging time.
First, when a large number of TLS requests arrive, it is the conventional practice to set an aging time point with the same expiration time for each newly generated Session, and then to age the Session at that time point. This causes a problem of concentrated aging. This embodiment sets a global variable, which is called time aggregator and is given in seconds, to be added with 1 each time a Session is newly generated.

Optionally, the initial aging length of time for the session is determined by a time aggregator by:
1) and determining the time point when the session is generated and the value of the time encryptor, namely adding 1 to the value of the global variable when the session is generated and determining the value of the time encryptor when the session is generated.

The time point is the current time point, and the time stamp time point of the system can be directly obtained. And the time of Session aging is the current time point + the configured aging time length + the time aggregator. Such a setting may achieve that at most one Session will age in one second. Since Nginx is multiprocess, but multiple processes share a Session Cache, each process maintains a time cipher, so that the number of sessions equivalent to Worker, which has Nginx at most, per second is aged.
