 Maximum Flow problem can be solved in polynomial time using a number of algorithms, for example the Ford-Fulkerson method or Push-relabel algorithms, both of which are described in \cite{intro}.
 
-This paper will introduce a generalization of this problem known as \define{Oblivious Routing} and proof the existence of an $\Oh(\log n)$ approximation scheme based on \cite{racke2008optimal} and described in \cite{approx}.

 After giving a definition of the problem, it is formulated as a linear problem and rewritten to yield the desired algorithm using a theorem giving an $\Oh(\log n)$ approximation of arbitrary metrics using tree metrics.
 Finally, the result is applied to give an $\Oh(\log n)$ approximation of the \define{Minimum Bisection} problem.
