Methods and apparatus for enhancing Mobile IP signaling and to support use of disparate addressing plans and dynamic Home Agent allocation in Mobile IP Regional Tunneling are described. The side members are folded along bend zones located between each of the first and second side members and the cross member such that, once folded, the first and second side members extend outward from the cross member forming a three-sided frame. The polymer backbone may be poly. At least one of a range of addressable data blocks described by at least one map entry of the map and a number of map elements copied per establish command is specified. In the process of reducing the remaining monomer, the dispersion of the colored polymer particles is treated by stripping in the presence of a specific antifoaming agent. It includes a coil assembly having an inlet and an outlet.
