“…In spite of not requiring significant changes in network elements, overlay mechanisms add complexity to the system and are not scalable. Such overlay deployments add excessive signaling load, energy consumption and CPU/memory overhead with control functions, most of them in a centralized way [1]. Moreover, the heterogeneity of current scenarios require cross-layering, where information can be potentially exchanged by non adjacent layers [2].…”

“…Thus, QoS support is of paramount importance for routing, and network resources must be provisioned so that sessions can experience low rates of propagation delay, jitter and packet loss end-to-end (E2E). The literature shows that current QoS-routing solutions (e.g., [2][3]) are inefficient, mainly in terms scalability, where per-flow approach place excessive signaling load, energy consumption and CPU/memory with control functions, most of them in a centralized way [4].…”

Abstract. The FP7 4WARD clean-slate Project envisions overcoming the limitations of current Internet by redefining it to efficiently support complex value-added sessions and services, such as location-based, health-care, criticalmission, and geo processing. The list of networking innovations from 4WARD's Future Internet (FI) proposal includes a new connectivity paradigm called Generic Path (GP), a common representation for all communications. From the networking point of view, a GP is mapped to a communication path for data propagation. For that, GP architecture relies on routing mechanism for selecting best communication paths. In order to assure reliable communications, the routing mechanism must efficiently provision QoS-aware multi-party capable paths, with robustness functions, while keeping network performance. Therefore, this paper proposes the QoS-Routing and Resource Control (QoS-RRC) mechanism to deal with the hereinabove requirements by means of an over provisioning-centric (bandwidth and paths) approach. QoS-RRC achieves scalability by avoiding per-flow operations (e.g., signaling, state storage, etc.). Initial QoS-RRC performance evaluation was carried out in Network Simulator v.2 (NS-2), enabling drastic reduction of overall signaling exchanges compared to per-flow solutions.

“…The IETF is currently developing the Next Steps in Signalling(NSIS) protocol suite, which consists of the Quality of Service NSIS Signalling Layer Protocol (QoS-NSLP) [1], the NAT/Firewall NSIS Signalling Layer Protocol (NAT-FW NSLP) [2] and the NSIS Transport Layer Protocol(NTLP) [3]. QoS-NSLP along with NTLP is expected to succeed the Resource reSerVation Protocol(RSVP) [4] to overcome its shortcomings [5] and also provide support for the use of transport layer security(TLS), sender and receiver initiation, QoS Models other than IntServ and DiffServ, incremental deployment, mobility among other things.…”
