IP MIB for IP Fast-Reroute draft-ietf-rtgwg-ipfrr-ip-mib-03 This draft defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes managed objects relevant for IP routes using IP Fast-Reroute [RFC5714
Design and Implementation of a Measurement-Based Policy-Driven Resource Management Framework For Converged Networks
This paper presents the design and implementation of a measurement-based QoS
and resource management framework, CNQF (Converged Networks QoS Management
Framework). CNQF is designed to provide unified, scalable QoS control and
resource management through the use of a policy-based network management
paradigm. It achieves this via distributed functional entities that are
deployed to co-ordinate the resources of the transport network through
centralized policy-driven decisions supported by measurement-based control
architecture. We present the CNQF architecture, implementation of the prototype
and validation of various inbuilt QoS control mechanisms using real traffic
flows on a Linux-based experimental test bed.Comment: in Ictact Journal On Communication Technology: Special Issue On Next

The FLUKA Model of IR8
The study of machine induced background (MIB), the radiation environment and beam dynamics of the LHC requires a detailed model of the machine tunnel, elements and electromagnetic fields. In this note, a specially created model of IR8 in FLUKA is described, including the tunnel, vacuum chambers, magnets, collimators, injection elements and shielding. The inclusion of all relevant machine elements in the LSS of IR8 results in a very flexible model suitable for a large variety of calculations and studies. The validation of the model is discussed, and some example applications described
Management of Digital Video Broadcasting Services in Open Delivery Platforms
The future of Digital Video Broadcasting (DVB) is moving towards solutions offering an efficient way of carrying interactive IP multimedia services over digital terrestrial broadcasting networks to handheld terminals. One of the most promising technologies is Digital Video Broadcasting-Handheld (DVB-H), at present under standardisation. Services deployed via this type of DVB technologies should enjoy reliability comparable to TV services and high quality standards. However, the market at present does not provide effective and economical solutions for the deployment of such services over multi-domain IP networks, due to their high level of unreliability. This paper focuses on service management, service level agreement (SLA) and network performance requirements of DVB-H services. Experimental results are presented concerning QoS sensitivity to network performance of DVB-H services delivered over a multi-domain IP network. Moreover, a solution for efficient and cost effective service management via QoS monitoring and control and network SLA design is proposed. The solution gives DVB-H operators the possibility of fully managing service QoS without being tied to third party operators
An Adaptive Flow-Aware Packet Scheduling Algorithm for Multipath Tunnelling
This paper proposes AFMT, a packet scheduling algorithm to achieve adaptive
flow-aware multipath tunnelling. AFMT has two unique properties. Firstly, it
implements robust adaptive traffic splitting for the subtunnels. Secondly, it
detects and schedules bursts of packets cohesively, a scheme that already
enabled traffic splitting for load balancing with little to no packet
reordering.
Several NS-3 experiments over different network topologies show that AFMT
successfully deals with changing path characteristics due to background traffic
while increasing throughput and reliability.Comment: submitted and accepted on IEEE LCN 2019, 4 pages, 5 figure

ALGORITHMIZATION, REQUIREMENTS ANALYSIS AND ARCHITECTURAL CHALLENGES OF TRACONDA
Globally, there are so much information security threats on Internet that even when data is encrypted, there is no guarantee that copy would not be available to third-party, and eventually be decrypted. Thus, trusted routing mechanism that inhibits availability of (encrypted or not) data being transferred to third-party is proposed in this paper. Algorithmization, requirements analysis and architectural challenges for its development are presented
