To remedy this problem, many proposals, such as window-based mechanisms (HSTCP and STCP), rate-based ones (Fast TCP) and router-assistant ones (XCP), have been suggested. The recent researches show that the buffer size in routers heavily affects the performances of HSTCP, especially network efficiency. This paper studies the performances of general window-based mechanisms, such as buffer occupancy, network efficiency and packet loss. The study of buffer occupancy shows that large increment function and small buffer size will result in pseudo-congestion, from which HSTCP and slow start of TCP suffer, under-utilizing the capacity of bottleneck link. We propose asymptotic square increase (ASI) mechanism, whose increment function is an increase additive function. Not to cause pseudo-congestion, a design principle of the buffer size of routers is given for the increment function of additive increase (AI), Multiplicative Increase (MI) and ASI. In this paper, the study of network efficiency shows that the concave increase mechanisms can obtain more network efficiency at smaller cost of packet loss than additive and convex ones","PeriodicalId":425107,"journal":{"name":"4th Annual Communication Networks and Services Research Conference (CNSR'06)","volume":"57 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124395699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zeadally","doi":"10.1109/CNSR.2006.12","DOIUrl":"https://doi.org/10.1109/CNSR.2006.12","url":null,"abstract":"Recently, there has been increasing interest in applying MPLS (multi-protocol label switching) to IP-based wireless access networks. During a handover on a mobile MPLS-based network a registration update message is sent from the foreign agent (FA) to the home agent (HA) which results in a handover delay. There have been proposals for handover processing mechanisms over MPLS-based networks using micro-mobility to decrease the amount of signaling delay between the HA and the FA. Unfortunately, network delays still occur when the demand on the network exceeds its capacity. This makes it difficult to guarantee QoS. In this paper we propose to isolate multimedia traffic from the other traffic flows as in dynamic-class based threshold (D-CBT). Non-multimedia traffic will be forwarded to the active queue management (AQM) system. We implemented load balancing on AQM for multimedia traffic. In this paper, we propose an approach that dynamically adjusts the threshold on multimedia traffic and Drop/Mark probability based on queue length, output rate, and media access delay on a micro-mobility on a MPLS-based network. Our simulation results show that our proposed technique provides maximum resource utilization, and decreases the number of packets dropped. In addition, our proposed method also yields lower average queue length","PeriodicalId":425107,"journal":{"name":"4th Annual Communication Networks and Services Research Conference (CNSR'06)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125704662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analytical modeling is the method of choice for fast and cost effective evaluation of a network protocol. One of the most efficient high level formalisms used for analytical modeling of network protocols is stochastic Petri nets (SPN's). Yet, complexity of nowadays network protocols, which results in the state space explosion of the underlying Markov Chains (MC) model, has hindered the wide use of SPN's in the analysis of these protocols. Decomposition techniques are considered one of the main methodologies used for the approximate solution of the state explosion problem. Unfortunately, most of these techniques either require special form of the model or give insufficient accuracy of the solution. Moreover, small rates of communication protocols have caused additional overhead on any proposed technique for approximate evaluation of these protocols. This paper presents a novel decomposition technique called behavior and delay equivalent block (BDEB) technique. This technique overcomes most of drawbacks of other techniques proposed in the literature. It introduces a new aggregation method that depends on using a new type of transitions called intelligent transition. The proposed technique adopts delay equivalent criteria but in a new philosophy different from other techniques using the same criteria. The new technique is explained by applying it to a scalable model of the courier protocol","PeriodicalId":425107,"journal":{"name":"4th Annual Communication Networks and Services Research Conference (CNSR'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129481676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This form of LSP is needed for establishing uni-directional multicast shared trees. Such trees are required for information distribution in applications such as video conferencing. The presented architecture is intended for multicast applications within a single autonomous domain and can be extended to cover inter-domain multicast sessions. We propose the use of one (or more) control points in the network called Rendez-vous points (RP) in a simple extention may utilize more than one RP to implement RP failure the PIM-SM protocol to implement multicast in MPLS networks. This architecture has the advantage of using existing MPLS techniques and existing routing protocols and requires only the addition of more management capabilities at the RPs. The experiments we carried out show that while retaining the advantages of using MPLS over traditional multicast routine, the performance of the new architecture is comparable to that of IP multicast in terms of the volume of control messages and label and memory consumption. Also the architecture scales well with the increase of the number of senders within a multicast group and with the increase of the number of multicast groups","PeriodicalId":425107,"journal":{"name":"4th Annual Communication Networks and Services Research Conference (CNSR'06)","volume":"208 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122619209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
