Handling link failures is the fundamental task of routing schemes. Routing protocols based
on link state (eg, OSPF) require a global state advertisement and re-computation when link …

Forwarding decisions in classical IP-based networks are predetermined by routing. This is
necessary to avoid loops, inhibiting opportunities to implement an adaptive and intelligent …

Due to increasing requirements related to quality of service and network dependability,
several IP Fast-Reroute mechanisms have been designed to limit the consequences of one …

We develop approaches for disjoint multipath routing and fast recovery in IP networks that
guarantee recovery from arbitrary two link failures. We achieve this by developing the first …

In order to achieve resilient multipath routing, we introduce the concept of independent
directed acyclic graphs (IDAGs) in this paper. Link-independent (node-independent) DAGs …

The mission critical network infrastructures are facing potential large region threats, both
intentional (like EMP attack, bomb explosion) and natural (like earthquake, flooding). The …

This paper develops novel mechanisms for recovering from failures in IP networks with
proactive backup path calculations and Internet Protocol (IP) tunneling. The primary scheme …

This paper presents Packet Re-cycling (PR), a technique that takes advantage of cellular
graph embeddings to reroute packets that would otherwise be dropped in case of link or …

Bursts, sudden surges in network utilization, are a significant root cause of packet loss and
high latency in datacenters. Packet deflection, re-routing packets that arrive at a local …

In this paper we present techniques and protocols for protecting a network against multiple
link failures. The existing link-based restoration with MPLS Fast Re-route (FRR) is fast, but …
