The objective of this project is the evaluation and improvement of new routing and forwarding architectures for the Internet. We consider three major challenges: fast protection (1), scalable multicast forwarding (2), and forwarding flexibility (3). These issues are also addressed in various working groups (WGs) of the standardization body of the Internet, the Internet Engineering Task Force (IETF). Fast reroute (FRR) methods are developed in RTGWG (1), scalable multicast is designed in the BIER WG (2), and protocols for flexible forwarding based on locator/identifier (Loc/ID) split are defined in the WGs LISP and IDEAS (3).In this project, we will develop and investigate FRR methods with only little overhead for software-defined networking (SDN) by leveraging and extending methods that have been proposed for IP networks (1). We will design FRR methods for scalable multicast (BIER) by leveraging IP-FRR approaches, advance the SDN-like BIER-TE including a prototype,and evaluate and improve the scalability of both resilient BIER and BIER-TE (2). Furthermore, we intend to make Loc/ID split more applicable. This comprises adding more privacy and accountability to forwarding protocols based on Loc/ID split (e.g., LISP, HIP or ILNP). Moreover, we will give a survey on typical use cases for Loc/ID split and categorize them, and we will advance DNS-AS, a novel indirection-based traffic engineering method for IP-based networks, and investigate its potential.
