State-of-the-art hardware based techniques achieve high performance and maximize efficiency of packet classification applications. The predominant example these, ternary content addressable memory (TCAM) systems can much higher throughput than software-based techniques. However, they suffer from power consumption due to the highly parallel architecture lack high-throughput range encoding In this paper, we propose a novel SRAM-based with packet-side search key units, significantly reducing...
Packet classification has become an important problem to solve in modern network processors used networking embedded systems such as routers. Algorithms for matching incoming packets from the pre-defined rules, have been proposed by a number of researchers. Current software-based packet techniques low performance, prompting many researchers move their focus new architectures encompassing both software and hardware components. Some newer exclusively utilize Ternary Content Addressable Memory...
Due to the expensive hardware and complex management of traditional middlebox, a concerted effort toward virtualized middlebox has been launched in both academia industry. In this paper, we propose unified model, MBBrick, which is composed three operation modules (classifier, rewriter, forwarder) control module. We then design language, describe MBBrick process. By concatenating different modules, can achieve functions middleboxes or service chains one single super middlebox. framework for...
The state-of-the-art language models (LMs) are n-gram models, which, for Chinese, word-based n-grams. To construct Chinese LMs, we need to have a lexicon and word segmentation (CWS) step. However, there is no standard definition of in it always possible new words by combining multiple characters, which causes out-of-vocabulary (OOV) problems. These make CWS being difficult ill-defined, deteriorates the quality LMs. Recently, conditional random fields (CRFs) been shown ability perform robust...
Due to the complexity of network structure and high growth transmission speed, measurement management are facing serious challenges. The traditional bottom-up telemetry methods no longer applicable complex scenarios. To bridge this gap, we propose IntStream, an intent-driven streaming framework allow operators measure analyze traffic. However, there three key challenges building intent-based system: (1) diversity data sources. (2) tasks. (3) low overhead requirements system. IntStream...
Due to the complexity of network structure and high growth transmission speed, measurement management are facing serious challenges. The traditional bottom-up telemetry methods no longer applicable complex scenarios. To bridge this gap, we propose IntStream, a flexible, expressive scalable framework allow operators measure analyze through passive stream processing active probing. However, there three key challenges building an intent-based system: (1) diversity data sources. (2) tasks. (3)...

Due to the expensive hardware and complex management of traditional middlebox, a concerted effort towards virtualized middlebox has been launched in both academia industry. In this paper, we propose unified model, MBBrick, which is composed three operation modules (classifier, rewriter, forwarder) control module (the mcontroller). We then design language, MG, describe MBBrick process. By concatenating different modules, can achieve functions middleboxes or service chains one single super...
Packet classification is an important aspect of modern network systems. systems have traditionally been built utilizing Ternary Content Addressable Memory (TCAM) due to the high throughput needed. However, TCAMs are expensive in terms area and power consumption. An alternative TCAM based using SRAM a novel rule encoding method has proposed match multiple packets simultaneously (using store_compare_units). This achieves similar or better than traditional approach while occupying smaller space...
Unmanned surface vehicles (USVs) are performing a variety of tasks today. Catamarans kind widely used USVs. A well-designed path planning is basis for USVs' safe navigation. However, some methods proposed may generate wrong results due to incomplete state records, and as far we know, few researchers have emphasized analyzed this question. This paper also proposes bidirectional A*-FMM method close-to-optimal paths catamarans in known environments, considering their kinematic constraints....
