I need to share my views in this discussion. Upto my search, the number of links whether odd or even does not make any difference in performance. The SLS or Signaling Link Selection field with 4 bit length is declared in start of every signaling transaction. This load sharing is also dependent on the algorithm that governs the process. anyhow this is a healthy discussion and i would try to bring some details. as for as my experience, i have seen about 99% of even number of links. Even it could be due to the fact that one additional sharing link for other one. Always 1+1 will be like redundant.
