Question $193$ pts $4\mathrm{.}5-3.$ The end$-$to$-$end principle. Which of the statements below are true statements regarding the "end$-$to$-$ end principle"? Check all that apply. The end$-$to$-$end argument advocates placing functionality at the network edge to optimize performance, such as end$-$end delay. The end$-$to$-$end argument advocates placing functionality at the network edge because some functionality cannot be completely and correctly implemented in the network, and so needs to be placed at the edge in any case, making in$-$ network implementation redundant. The end$-$to$-$end argument allows that some redundant functionality might be placed both in$-$network and at the network edge in order to enhance performance.
