Embodiment 1
[0085] figure 1 A flowchart showing a method for accessing a space network according to an embodiment of the present invention. Such as figure 1 As shown, the method mainly includes:
[0086] Step S11, the core routing node of the space network obtains the ToS field of the IP data packet;
[0087] Step S12, parsing the ToS field to obtain the user priority in the ToS field; and
[0088] Step S13. Determine the access mode for the terminal to access the space network according to the user priority.
[0089] Specifically, the first three digits of the ToS can be defined as a user priority field, which indicates the service level of the user. Wherein, when the first three digits of the ToS are "000", it means that the corresponding user is the user of the lowest service level, and it is determined to use the GEO access mode to access the space network. When the first three digits of ToS are "001", "010", "011" or "100", it means that the corresponding user is a user of mediu...
Embodiment 2
[0092] figure 2 A flowchart showing a method for accessing a space network according to another embodiment of the present invention. Such as figure 2 As shown, the main difference between this method and the previous method is that: the service class is also defined in the ToS field in advance, and the access mode for the terminal to access the space network is selected based on the two factors of user priority and service class. The methods specifically include:
[0093] Step S21, obtaining the QoS field of the IP data packet;
[0094] Step S22, analyze the ToS field, determine the user priority field, if the user priority field is the third level, perform step S26; if the user priority field is the second level, perform step S23; if the user priority field is the first grade, execute step S28;
[0095] Step S23, judging whether the user priority field in the ToS field is low or high in the second level, if it is judged to be low in the second level, perform step S24; i...
Embodiment 3
[0112] Figure 5 A flowchart showing a method for accessing a space network according to another embodiment of the present invention; in this embodiment, queue scheduling is also performed based on user priority, such as Figure 5 As shown, the method includes:
[0113] Step S41, implementing queue scheduling based on the user priority field in the ToS field. Such as Figure 6 shown, including:
[0114] Step S411, assigning weights to each user queue;
[0115] For example, you can assign values "101" to "000" to each user queue, and the user priority indicated by the value decreases in turn, and the assigned weight corresponds to the priority field in the ToS field, so that the user gets the same priority as the priority field. scheduling opportunities.
[0116] Step S412, initializing the counter value of each user queue as the priority field in the corresponding ToS field;
[0117] Step S413, judging whether all queues are empty, if yes, end, otherwise enter step S41...
