This thesis introduces the concept of compact forwarding in the field of content-oriented net-works. The main idea behind this concept is taking a probabilistic approach to the problem of packetforwarding in networks centered on content identifiers rather than traditional host addresses. Thefundamental question explored is where to place the packet forwarding state, in network nodes...

Flecs is a framework for facilitating rapid implementation of packet forwarding protocols. Forwarding functionality of communication protocols can be modeled by a combination of packet processing components called abstract switching elements or Ases. Each Ase is constrained by the axioms of communication which enables us to formally analyze forwarding mechanisms in communication networks. Ases ...

This memo discusses Flow Attribute Notification Protocol (FANP), which is a protocol between neighbor nodes for the management of cut-through packet forwarding functionalities. In cut-through packet forwarding, a router doesn’t have to perform conventional IP packet processing for received packets. FANP indicates mapping information between a datalink connection and a packet flow to the neighbo...

In this paper, we present a novel packet forwarding scheme for wireless ad hoc networks --“Direction” Forwarding (DFR). Popular routing protocols such as DSDV and AODV use “predecessor” based forwarding, namely, the packet is forwarded to the predecessor on the shortest path from the destination, as advertised during the last update. Predecessor forwarding may fail in large scale networks where...

This work introduces a significant improvement for optical packet switching network based on OC processing. The key point of this method is the generalization of the optical label switching concept to forward optical packet without label swapping and O/E/O procedure. Our proposed method simplifies the design of switch devices in optical domain and packet forwarding process which speeds up packe...

Fairness in wireless sensor networks demands event nodes to have an equal share in the overall throughput of the system. Fairness is difficult to achieve in sensor networks due to multiple hop packet forwarding to a single destination that results in congestion. Moreover, greater the density of event region greater is the level of interference and greater is the number of packet drops. In this ...

— In Geographic Routing protocols (e.g. GPSR), a node makes packet forwarding decisions based on the coordinates of its neighbors and the packet’s destination. Geo-routing uses greedy forwarding as a default; if this fails (e.g. the packet is trapped in a dead end caused by holes and/or obstacles), a recovery scheme based on perimeter routing is invoked. This however often leads to degraded per...

Due to increase in the multimedia applications and streaming servers, transport of MPEG compressed video data through a packet switched network has become highly important. It is necessary to transport the video while ensuring appropriate video quality at the receiving end. This paper proposes a new N2N packet forwarding technique that reduces the packet loss and delay jitter of the video traff...
