Examples
example 1
[0049] Example 1: Both SS1 and SS2 are type 2 synchronization sources and neither has data transfer
[0050] In this case, both sync sources will use the configured first maximum backoff value
[0051] Such as Figure 3A As shown, at time t0, SS1 and SS2 are far away from each other, and they serve as independent synchronization sources respectively.
[0052] As SS1 and SS2 gradually approach, at time t1, the distance between the two is close enough to start simultaneously or substantially simultaneously such as figure 2 The coordination process among synchronization sources shown in .
[0053] For example, SS1 and SS2 each produce a Random integer values within w1 and w2. Here, without loss of generality, it is assumed that w1 is smaller than w2.
[0054] Next, SS1 operates normally for w1 cycles. At time t2 at the end of w1 cycles, SS1 determines that SS2 has not adjusted its synchronization to SS1 (eg Figure 3A As shown in , SS2 is still during w2 cycles of it...

[0057] Example 2: Both SS1 and SS2 are type 2 sync sources and both have data transfers
[0058] In this case, both sync sources will use the configured second largest backoff value
[0059] and Figure 3A similar in, such as Figure 3B As shown, at time t0, SS1 and SS2 are far away from each other, and they serve as independent synchronization sources respectively.
[0060] As SS1 and SS2 gradually approach, at time t1, the distance between the two is close enough to start simultaneously or substantially simultaneously such as figure 2 The coordination process among synchronization sources shown in .
[0061] For example, SS1 and SS2 each produce a Random integer values within w1 and w2. Here, it is still assumed that w1 is smaller than w2 without loss of generality.
[0062] Next, SS1 operates normally for w1 cycles. At time t2 at the end of w1 cycles, SS1 determines that SS2 has not adjusted its synchronization to SS1 (eg Figure 3B As shown in , SS2 is still ...
example 3
[0066] Example 3: Both SS1 and SS2 are type 2 sync sources, where one sync source (eg SS1) has no data transfer and the other sync source (eg SS2) has data transfer
[0067] In this case, SS1 will use the configured first maximum fallback value while SS2 uses the configured second largest fallback value
[0068] Such as Figure 3C As shown, at time t0, SS1 and SS2 are far away from each other, and they serve as independent synchronization sources respectively.
[0069] As SS1 and SS2 gradually approach, at time t1, the distance between the two is close enough to start simultaneously or substantially simultaneously such as figure 2 The coordination process among synchronization sources shown in .
[0070] For example, SS1 and SS2 each produce a and range Random integer values within w1 and w2. Here, it is still assumed that w1 is smaller than w2 without loss of generality.
[0071] Next, SS1 operates normally for w1 cycles. At time t2 at the end of w1 cycles, SS...
