The basic function of the Internet is to delivery data (what) serve needs all applications. IP names attachment points (where) facilitate ubiquitous interconnectivity as current way deliver data. fundamental mismatch between and naming leads a lot challenges, e.g., mapping from name address, handling dynamics underlying topology, scaling up distribution, securing communication, etc. Information-centric networking (ICN) proposed shift focus communication paradigm where what, by making named...

Information-Centric Networking is (ICN) [1] gaining increasingly concerns, as an important direction of the Future Internet Architecture research. Although In-network caching considered one most significant properties ICN, cache policy for ICN still little explored. In this paper, we formulate in-network problem into Mixed-Integer Linear Programming problem. We also propose a novel named LB (Least Benefit) with taking account distance factor and new forwarding scheme shallow flooding (FSF...

In this paper, we proposal an content provider mobility solution of Named Data Networking (NDN) [1]. Here means the host NDN network which provide originally. We add a Locator are to Interest packet [2]. Mapping System also introduced into network, maps identifier locator. The original name is used as identifier. Thus, matching lookup in Content Store (CS) and Pending Table (PIT) employs identifier, while forwarding Forwarding Information Base (FIB) reality, should be DNS-like distributed...

We propose compressed PIT structure based on Bloom Filter. And we argue that United Filter is better than Counting in the compression.

Cloud gateways are fundamental components of a cloud platform, where various network functions (e.g., L4/L7 load balancing, address translation, stateful firewall, and SYN proxy) deployed to process millions connections billions packets. Providing high-performance failure-resilient packet processing with scalable traffic management mechanism is crucial ensuring the quality service provider, hence great importance. Many nowadays implemented in software commodity servers for low cost high...

There have been many load balancing solutions for datacenter networks. Almost all of them require modifications to the network fabric or/and virtual machines. Recently, switch layer becomes an ideal location operators deal with problem. In this paper, we propose Virtual Multi-channel Scatter (VMS), a packet-level design in layer. VMS scatters packets one TCP flow several different forwarding paths (channels). has noteworthy properties. First, is low cost and transparent tenants. It can be...

While extending network programmability to a larger degree, P4 also raises the risks of incurring runtime bugs after deployment programs. These bugs, if not handled promptly and properly, can ruin functionality performance networks. Unfortunately, absence debuggers makes troubleshooting program challenging intricate for operators. This paper is devoted on-the-fly debugging in P4-enabled We propose P4DB, general platform that empowers operators debug programs three levels visibility by...

As a design of information-centric network architecture, Named Data Networking (NDN) provides content-based security. The signature binding the name with content is key point security in NDN. However, signing will introduce significant computation overhead, especially for dynamically generated content. Adversaries can take advantages such overhead to deplete resources provider. In this paper, we propose Interest Cash, an application-based countermeasure against Flooding dynamic Cash requires...

CCN is one of the future Internet architecture. However, lack real traffic becomes an obstacle to advanced researches. HTTP, as content-oriented application-layer protocol working over current Internet, similar in many aspects. In this demo, we try convert HTTP into with HTTP-CCN gateway. Although not equivalent CCN, can design carefully make conversion correct most situations. The gateway will introduce testbed support Our demonstration show how use

This paper explores resource allocation strategy in the Baidu Over The Edge system to enable mobile edge computing (MEC) datacenters effectively support cloud-native services downstream network edge. There are many challenges this issue. First, MEC resource-constrained fully meet demands. Second, previous works regard requirements of each service as an indivisible unit, resulting idle resources, even if resources can demands some microservices decoupled by service. Third, they confined...

While extending network programmability to a more considerable extent, P4 raises the difficulty of detecting and locating bugs, e.g., program bugs missed table rules, in runtime. These runtime without prompt disposal, can ruin functionality performance networks. Unfortunately, absence efficient debugging tools makes bug troubleshooting intricate for operators. This paper is devoted on-the-fly programmable data planes. We propose P4DB, general platform that empowers operators debug programs...

There have been many traffic balancing solutions for datacenter networks. All of them require modifications to the network fabric or/and virtual machines. In this paper, we propose Virtual Multi-channel Scatter (VMS), a new solution in VMS works switches between and It can be deployed by operators at relatively low cost without extra restrictions machine users. scatters packets one TCP flow several different forwarding paths. employs an adaptive path selection based on window size We...

This paper presents an easy matrix computation based simulator of NDN network architecture. is just like Newtonian mechanics in some way, once given the system initial state, routing table, content distribution, data requesting information network, can figure out all subsequent state on operation. turns packet process event, such as interest generating, forwarding, hitting and transmitting, to scale. much easier use than NS3 CCNx, but it provide similar simulation result more details. And...

Coflow scheduling without prior knowledge has been proposed recently. However, the previous solution, Aalo, two problems: it does not explicitly control flow rate; assumes network is ideally non-blocking (with perfect traffic balancing and no oversubscription). In this paper, we show performance loss caused by above problems. We propose EAalo to cope with It three enhancements Aalo: per-flow bandwidth enforcement, centralized oversubscription adaption. evaluate simulations. The simulation...

Accurate per-flow counting is beyond the capability of network switches due to sheer flow number. The conventional divide-and-conquer method by distributing traffic multiple servers for software processing costly. solution therefore quests a combination hardware and where with limited resources aims undertake part job reduce workload software, achieving desirable balance cost performance. To this end we design FASTeller be deployed on SmartNICs. It tuned maximize aggregation level in...
