Embodiment 3
[0176] It should be noted that, in the third embodiment, the cache processing method compares the stay time of a certain data content on the local node, the stay time of the data content on the next-hop node, and the data content prefix corresponding to the data content The residence time of the last hop node is used to judge whether the data content can be cached in the cache area of this node. The third implementation will be described below.
[0177] exist figure 2 based on, further, for figure 2 In step 103, the interest packet also includes: the stay time of the previous hop node.
[0178] exist figure 2 Based on the provided cache processing method, step 106 specifically includes:
[0179] Query whether there is an entry corresponding to the data content prefix information in the PIT, and if so, add the sending interface identifier corresponding to the data content prefix information and the stay time of the previous hop node corresponding to the data content pr...
Embodiment 4
[0214] It should be noted that, in the fourth embodiment, the cache processing method judges whether the data content can be cached in the in the cache of this node. The fourth implementation will be described below.
[0215] exist figure 2 Based on the provided cache processing method, step 106 specifically includes:
[0216] The node inquires whether there is an entry corresponding to the data content prefix information in the PIT, and if so, adds the sending interface identifier corresponding to the data content prefix information to the entry.
[0217] If not, a new entry is created, and the sending interface identifier corresponding to the data content prefix information is added to the new entry.
[0218] Query the forwarding information base FIB, and forward the Interest packet to the next hop node.
[0219] Specifically, as shown in Table 2 below, the node queries the PIT. If there is an entry of data content prefix information j in the PIT, it will add the sendin...
Embodiment 5
[0251] It should be noted that, in the fourth embodiment, the cache processing method judges the data content by comparing the stay time of a certain data content on this node with the stay time of the previous hop node corresponding to the data content prefix of the data content Whether it can be cached in the cache area of this node. The third implementation will be described below.
[0252] exist figure 2 based on, further, for figure 2 In step 103, the interest packet also includes: the stay time of the previous hop node.
[0253] exist figure 2 Based on the provided cache processing method, step 106 specifically includes:
[0254] Query whether there is an entry corresponding to the data content prefix information in the PIT, and if so, add the sending interface identifier corresponding to the data content prefix information and the stay time of the previous hop node corresponding to the data content prefix information to the entry;
[0255] If not, create a new...
