Solving Mobility Above the Network Layer ■ Reconfiguration of the host for its new network:Protocols discussed in Chapter 1, “ntroduction to“Mobility”,”such as Dynamic Host Configuration Protocol (DHCP),IP auto-configuration,and router discovery mechanisms,are widely deployed techniques for accomplishing this function. Ensuring reachability for new connections:Protocols discussed in Chapter 2, "Internet "Sessions","such as Dynamic DNS,provide sufficient capabilities for this function. Updating existing connections and rebinding these connections to the new IP address:Numerous protocols can provide this function.Solving Mobility Above the Network Layer
