“…In addition to the above detailed layer 1 implementation, it can also be implemented at layer 1 using Next Generation SONET (NGS) protocols [37], and in particular the Generic Framing Protocol (GFP). Since data units from different higher layer protocols are encapsulated in the payload field of GFP frames, the payload field can be used to accommodate the encoded (added) data units.…”

This paper serves as a tutorial lecture on the use of network coding to provide resource efficient, and agile proactive protection. Network coding, which was introduced in [1], allows intermediate network nodes to form linear combinations of packets received on different input links. The use of network coding results in capacity enhancement. This capacity enhancement is used to provide protection channels which are used to carry combinations of redundant data, and are solved by the receivers in order to recover data lost due to network failures.The paper starts by addressing network coding-based protection of bidirectional unicast connections, and explains the use p-Cycles to carry linear combinations of the redundant data units. The paper also discusses an earlier protection strategy which is based on diversity coding, in which the linear combinations are formed at special nodes, including sources, and is used to protect unidirectional connections. A generalized network coding-based protection which uses a tree to carry the linear combinations will be presented. Protection of multicast connections using network coding is also explained

“…Legacy telephone networks and SONET/SDH networks, in particular, impose a rigid hierarchy of rates that are multiples of a voice channel (i.e., 64 Kbps), hence, there is a proliferation of data services with rates ranging from DS-1 (1.5 Mbps) and DS-3 (45 Mbps) to STS-3 (155 Mbps) and STS-48 (2.5 Gbps) and beyond. These services are implemented by mapping a user's payload directly onto specific time slots of the transport system, e.g., using the generic framing procedure (GFP) [8], [21], [24].…”

Abstract-Many network operators offer some type of tiered service, in which users may select only from a small set of service levels (tiers). Such a service has the potential to simplify a wide range of core network functions, allowing the providers to scale their operations efficiently. In this work, we study a number of problem variants related to service tier selection. Our contributions include: 1) a faster algorithm for obtaining optimal service tiers; 2) a new formulation and optimal algorithm to optimize jointly the number and magnitude of each service tier; and 3) the concept of "TDM emulation" in which all service tiers are multiples of the same (software-configurable) bandwidth unit, and a suite of algorithms to select jointly the basic unit and service tiers. Our work provides a systematic framework for reasoning about and tackling algorithmically the general problem of service tier selection, and has applications to a number of networking contexts, including access networks (e.g., determining the tiers for ADSL, cable modem networks or PONs) and core networks (e.g., LSP sizing for MPLS networks).

“…Generic framing procedure: Generic Framing Procedure (GFP) [11][12][13] is a new standard that has been developed to overcome data transport inefficiencies and deficiencies inherent in the existing ATM and PoS protocols. HDLC protocols like PoS need nearly twice the genuine data bandwidth to transmit the packet.…”

This study presented a new data link layer design for the virtual bus architecture. The virtual bus is a hierarchical access network offered a broadcast capability for data and signaling. The proposed of the study is to support Quality of Service (QoS) in network. During study, the most promising technology capable of delivering full service access at high data rates is Synchronous Digital Hierarchy (SDH)/Synchronous Optical Networking (SONET). For that reason, we develop SDH/SONET as a physical layer for the virtual bus network. The main goal of this investigation was to study the performance of transmission medium and the overall performance of the network. We exemplify a Multiple Access Protocol (MAP) with Generic Frame Procedure (GFP) for transmitting IP network protocol datagram over SDH/SONET. This is a novel method for transmitting MAP with GFP. The protocol adds multi-terminal access capability to an inherently point-to-point link. It enabled the design of seamless networking environments using SDH/SONET as the transmission medium for Metropolitan Area Network (MAN). The new frame mapping protocol is known as Virtual Bus Transport (VBT). The performance of multiple traffic generators in a virtual bus network is of major interest for mobile network provider. We used OMNeT simulation tool to evaluate the result. Through the simulation it proved that the VBT scheduling technique offers better treatment mainly to the higher Qos requirement traffic.
