Mobility First : Multihoming Extension

---

Introduction

​MobilityFirst (MF) is an emerging proposal for the new standard of the 5G networking! Mobility first takes a new approach to the Internet by focusing on increasingly dominating communications of mobile devices. The new architecture will pave the ground for a variety of new features including improved scalability, robust wireless signals, enhanced security, a context-sensitive network among other goodies. More information about MobilityFirst can be found on their website (​link). A brief introduction of the relevant concepts are summarized below.

The old TCP/IP model worked great with servers and desktops that staid put for most of the time. A deskptop computers' identity is closely attached to its network address. With MF, identities of machines (ID) are separated from their network address (NA). Instead of using static IPs to identify machines, all devices now have Dynamic Name Address Bindings. These bindings are called Global Unique Identifiers (GUID). Hence, all machines must go through a Global Name Resoltion Service (GNRS) which indicates the routing needed to reach said address. The GNRS uses a Distribtued Hash Table (DHT) to store routing information in a loosely decentralized way. But unlike the DNS, the GNRS applies to all GUIDs.

Multihoming is a concept that allows for a single device to use multiple interfaces at once. Our goal is to implement multihoming in the MF framework and create improvements to the the efficient division of work between hosts as well as proper lead balancing throughout the network said data is routed through.
