There are hundreds of billions packets passing through the network, how to analyse these big data is an arduous task. In this paper we proposed a new scheme based on cluster algorithm to explore the backbone network traffic pattern. Two new traffic features are introduced to assist the analysing process. These two novel attributes can represent the flow effectively cooperated with a new flow similarity...
Congestion management is likely to become a critical issue in interconnection networks, as increasing power consumption and cost concerns lead to improvements in the efficiency of network resources. In previous configurations, networks were usually oversized and underutilized. In a smaller network, however, contention is more likely to occur and blocked packets cause head-of-line (HoL) blocking among...
This paper studies the IP network routing algorithm based on mathematical theories and methods. It has analyzed the limitation based on distance vector of routing protocol RIP and based on links the routing protocol OSPF. It proposes an improved Dijkstra algorithm, makes the routers and communication links of the cost (transmission speed and delay) can taken into account. In view of distributed multimedia...
A general billing method of NGN (new generation network) is analyzed and presented on the basis of comprehensively considering business type (data, voice, video, etc.), call type (local, district, long-distance, etc.), billing mode (based on time-period or traffic), QoS (Quality of Service) level, date and time. The method uses the above-mentioned factors as variables, with a group of formulas to...
Defined by the 3GPP, the IP multimedia subsystem (IMS) is an architectural framework that enables the delivery of multimedia services in mobile networks. Based on the session initiation protocol, the IMS offers unified billing, QoS negotiation mechanisms, and the possibility of combining services deployed in different environments like CAMEL and Parlay OSA. With the aim of determining the real limitations...
Service creation by composing existing services and/or network resources is considered by Telecom and Internet industries as the trend for service provisioning in next generation networks. Related research work is being carried out for years, and various service composition approaches have been proposed by different standardization organizations and companies catering to different network requirements...
Multimedia real time applications are rapidly growing across the Internet. The significant growth of such type of traffic indicates the need to provide special treatment across the Internet. Current Internet which is based on IPv4 is unable to provide more than the best effort service. IPv6 as the next generation protocol has the greater capability to fulfill the requirements of newly emerging real...
We envision that future field-programmable gate arrays (FPGAs) will use a hardwired network on chip (HWNoC) as a unified interconnect for functional communications (data and control) as well as configuration (bitstream for soft IPs). In this paper we present a 3-tier reconfiguration model that uses the HWNoC as the underlying platform to realize dynamic loading, starting, and stopping of applications...
Along with the rapid development of network technology, the application of internet is wider. The network service also presents the characteristics of diversification. Thus the traditional real-time services have not already people's need. Immediately what to produce is various multi-media businesses such as, video, audio, the television meeting etc. with high request of real time. The traditional...
We envision that future FPGA will use a hardwired network on chip (HWNoC) as a unified interconnect for functional communications (data and control) as well as configuration (bitstream for soft IPs). In this paper we present a reconfiguration methodology which makes use of such a platform to realize composable inter-application communication and persistent-state intra-application when run-time partial...
Owing to the heterogeneity and high degree of connectivity of various networks, there likely exist multiple available paths between a source and a destination. To be able to simultaneously and efficiently use such parallel paths, it is essential to facilitate high quality network services at high speeds. So, traffic splitting, having a significant impact on quality of services (QoS), is an important...
As more homes are becoming broadband enabled, a huge strain is placed on the underlying IP infrastructure. In being able to predict the types of traffic that nodes might generate, preference can be given to high priority, latency sensitive traffic. Traditionally, a home had a single computer utilizing a link to the Internet. In recent years this single computer was replaced by a multitude of smart...
The policy and charging control function is defined as PCC (policy and charging control) by 3GPP and SBBC (service based bearer control) by 3GPP2. It is valuable to establish an experimental testbed for PCC and SBBC to improve and verify the related performance. At present, we can make use of open source IMS (OSIMS) and UCT PCF to simulate 3GPP PCC, but there is no testbed for the policy control function...
Traditionally, IP Network planning and design is mostly based on average delay or loss constraints which can often be easily calculated. Jitter, on the other hand, is much more difficult to evaluate but this is particularly important to manage the QoS of real-time and interactive services such as VoIP and streaming video. In this paper, we propose a simple model for the delay jitter that is fast enough...
Virtualization, in telecommunication, has been given great interest over the 20 past years. Migrating operating system instances between physical hosts is one of the most important features of this technology. It allows network administrators to resolve serious problem such us hardware failure, lack in server capacity, while facilitates the management and the upgrade of their systems. With the strong...
With the rapid advance of computer and network technology, more and more applications are deployed in the customer-side network. These applications require different quality of service (QoS), but have to share a few bandwidth limited Internet connections. Owing to the IP network's best-effort delivery mechanism, the QoS requirements are hard to be satisfied. There have been plenty of QoS solutions...
Internet is becoming an indispensible infrastructure of essential media, which makes a great burden for ISP's security and traffic management. Especially the situation will be much more serious in NGI (the Next-Generation Internet) because of its innumerable users, mobile device, information appliances (IA) and networked sensors etc with 128-bit IPv6 address. For the reason of lacking scalability,...
Group applications like the audioconference require a minimum level of quality of service for the adequate transmission of voice packets and the improvement of the signaling processes for joining, maintaining and leaving multicast groups. Traditionally, SIP servers have dealed with unicast signaling and have also been supported by IP multicast facilities described within the SDP payload information...
Multicast technology introduces a number of new applications; meanwhile, it reduces the congestion of the network and releases the burden of the server. Those characteristics, such as reducing the occupied bandwidth, reducing server load, improving the quality of data transmission, are especially applicable to the needs of large bandwidth multimedia applications such as audio, video. This new technology...
Future networks are envisioned to satisfy the user needs and improve their quality of experience. This requires the networks to support context-aware information, where context of the user, session, network and environment will greatly influence the way the session is delivered: new approaches are required to deal with the overall context information and network reaction to constantly context changes...
