Although the fact that VPN provide a safe and reliable transfer of customers’ data, but the basic configurations on which they depend VPN and transport networks of asynchronous (ATM) and Frame Relay networks (FR).Link, that depend on them these techniques are relatively slow and cause a delay in time With the rapid growth of the Internet and increase the load on the network in terms of users and providers of service to look for ways of effective and fast routing packets of data while ensuring quality of service began(QoS)and class of service(Cos)and secure management and engineering movement(traffic) on the network and appeared the multiswitch tags of the Protocol(MPLS)standard modern technique verify the previous requirement safter she was initially way to improve the transmission speed routers. This paper presents an analytical study on improving the performance of virtual private networks using multi-protocol label switching( MPLS_VPN), by improving routing operations on the third level, minimizing the delays and complexity resulting from the routing on full internal routers in the traditional technical protocols settings and limited to Edge routers in networks MPLS_VPN. OPNET was used simulation software to get the results of the analysis and simulation of new technology and compare it with the old technology.

Research summary
تناقش الورقة البحثية تحسين أداء الشبكات الافتراضية الخاصة (VPN) باستخدام تقنية التبديل متعدد الوسوم للبروتوكول (MPLS). بالرغم من أن الشبكات الافتراضية الخاصة توفر نقلًا آمنًا وموثوقًا للبيانات، إلا أن التقنيات التقليدية مثل شبكات النقل غير المتزامن (ATM) وشبكات ترحيل الأطر (Frame Relay) تعتبر بطيئة نسبيًا وتسبب تأخيرًا زمنيًا. مع النمو السريع للإنترنت وزيادة الحمل على الشبكة، ظهرت الحاجة إلى طرق توجيه فعالة وسريعة لرزم البيانات مع ضمان جودة الخدمة وإدارة الحركة على الشبكة. تقنية MPLS توفر هذه المتطلبات من خلال تحسين عمليات التوجيه على مستوى الطبقة الثالثة وتقليل التأخير والتعقيد الناتج عن إعدادات بروتوكولات التوجيه التقليدية. تم استخدام برنامج المحاكاة OPNET للحصول على النتائج التحليلية للتقنية الجديدة ومقارنتها مع التقنية القديمة. أظهرت النتائج أن تقنية MPLS_VPN تقدم أداءً أفضل من الشبكات الافتراضية التقليدية من حيث سرعة التوجيه وتقليل كمية البيانات المهملة.

Nowadays, wireless networks are spreading more and more. The majority of installed networks have become wireless due to the simplicity of installation; where they do not need an infrastructure. This does not mean that the role of the wired networks i s being eliminated. Instead, the wireless networks are considered as a complementary of the wired networks. With all types of networks from personal and local area networks (PAN and LAN) to wide area networks (WAN) especially the Internet, research has become oriented to focus on the quality of service (QoS) and the integration among all these networks taking into account the Internet which is considered as the backbone for each network that wants to exchange the information with any other network all over the world. In our research, we take into account the quality of service in the broadband networks such as the WiMax network (Worldwide Interoperability for Microwave Access) with IEEE 802.16e standard which covers cities and supports the mobility. This network can be used to interconnect the rural zones with the center of cities, this kind is called point-to-point, or it can be used to cover the cities and is called point-tomultipoint, The last one is used to interconnect different wireless networks especially the local one which has infrastructure (Wi-fi: Wireless Fidelity) and networks which have many users and called hotspots. However, the cells of Wi Max in the cities are called hotzones. We propose a system model that performs the load balancing process between the base stations of WiMax network. This means, the proposed load balancing algorithm exchanges the terminals between the adjacent base stations in order to make the throughput in each base station equals to the throughput in the others. This will improve the performance of the overall network and increase the available bandwidth for each terminal; in addition, this will increase the number of terminals which can be served. On one side, these advantages return to the subscribers, they also return to the operator on the other side, not to mention the good renown that the operator will get from subscribers that will make more subscribers join to this network. The proposed load balancing system can be centralized; implemented in a centralized server connected to all base stations or distributed system implemented in each base station. The load balancing algorithm which consists of several steps is placed in a controller that achieves it. The load balancing process and the handover procedure have to be fast enough in order to prevent the adverse effect on the quality of service especially for the real-time applications users.
ASON\GMPLS based optical network technology has shown high reliability recently, but the issue of unified control of optical networks has become an urgent necessity to cover problems caused by separate control between different optical network layers . The attempt to implement GMPLS-based standardized control of Internet Protocol / Dense Wavelength Division Multiplexing (IP/DWDM) networks has yielded satisfactory results but reflected significant complexity when operating in real time. On the other hand, the OpenFlow control level is offered as a promising solution to be a uniform control level for such networks, but it is not yet effective enough to control optical switch nodes. Therefore, as an intermediate step towards a unified UCP level entirely based on the OpenFlow protocol, the logical thinking for the time being is to introduce an OpenFlow/GMPLS interoperability control level that uses GMPLS to control the optical layer and the dynamic coordination between the IP layer and the optical layers. This research presents a practical application of interoperability solutions (parallel, overlapping, and integrated) for GMPLS and OpenFlow control levels applied to the ASON optical network installed in the southern region of Syria. The results have shown that the integrated solution for uniform control is superior to parallel and overlapping solutions in terms of the overall path provision latency (OPPL), at the expense of the high complexity of the design and processing of the load within the controller.
Network coding isone of the important researches in multi-hop wireless networks domain and it widely participates in improving the performance of these networks, since it benefits from the broadcasting nature of transmission processes to transmit m ore than single packet in one broadcasting transmission. So it achieves double use of the available bandwidth, which can increase the throughput of the network and reduce the congestion.Our aim in this research is to verify the improvement that network coding presents to theperformance of multi-hops wireless Ad-hoc networks, and to study the accelerating of research process for coding chances through constructing a virtual queues according to the packets flows that pass the node, and applying affective manner to manage this queues.
Multi hop wireless networks face many challenges basically the limitation of bandwidth, loss of packets because of many problems in wireless medium also loss of paths because of the random and unpredictable movement of wireless nodes, which reduce the performance of these networks. Recently, Network coding has been used as promising technology that achieves the reliable transfer of data in wireless networks with high throughput. Considering the efficiency of this technology and with benefiting from both the same cost paths and the broadcasting property of wireless medium, a multi transmission mechanism for random linear network coding has been proposed in multi hop wireless networks, which depends on multicasting of coded packets on the same cost paths.
We use Hypergraph Attention Networks (HyperGAT) to recognize multiple labels of Chinese humor texts. We firstly represent a joke as a hypergraph. The sequential hyperedge and semantic hyperedge structures are used to construct hyperedges. Then, atten tion mechanisms are adopted to aggregate context information embedded in nodes and hyperedges. Finally, we use trained HyperGAT to complete the multi-label classification task. Experimental results on the Chinese humor multi-label dataset showed that HyperGAT model outperforms previous sequence-based (CNN, BiLSTM, FastText) and graph-based (Graph-CNN, TextGCN, Text Level GNN) deep learning models.
