This demonstration shows the hardware prototype of the IPclip (IP calling line identification presentation) mechanism for IPv6 networks. IPclip is a mechanism, which provides Trust-by-Wire in IP-based networks by adding trustworthy location information to IP packets. It is implemented on an FPGA development board and configurable at runtime via a graphical configuration tool. We show IPclip's basic...
Hash functions have a space complexity of O(n) and a possible time complexity of 0(1). Thus, packet classifiers exploit hashing to achieve packet classification in wire speed. Especially evolvable hash functions can adapt to a changing classification data base. But hash functions do have an important flaw. Some of the hashed keys may result in a large number of collisions. If those keys occur frequently,...
During the last decades, the Internet has steadily developed into a mass medium. The target group radically changed compared to, e.g., the 90s. Because virtually everyone has access to the Internet, threats due to insecurity and anonymity reach critical levels and have to be tackled by both carriers and Internet Service Providers. Regaining trust-by-wire, comparable to classic fixed line telephones,...
The capabilities of passive optical networks (PONs) are strongly influenced by the quality of the used dynamic bandwidth allocation (DBA) algorithm. DBA algorithms control the assignment of available upstream bandwidth to the users connected to the PON. In an oversubscribed environment, that poses a challenge regarding the selection of an appropriate DBA algorithm. Therefore, DBA algorithms are subject...
During the last decades, the Internet has steadily developed into a mass medium with millions of users. On the one hand, newfangled services replace traditional ones. Naturally, these are thereby expected to offer at least the same features as their classical pendants, e.g., when VoIP replaces traditional fixed line telephone networks. On the other hand, the requirements on network infrastructures...
During the last years, the Internet has grown into a mass-medium for communication and information exchange. Millions of people are using the Internet for business and in social life. Users can be reached easily and cost-effectively. Unfortunately the Internet's open structure is the reason for its frequent misuse for illegal and criminal actions such as dissembling phishing attacks. Thus, anti-phishing...
In modern network applications and especially in Access Networks, the demands towards functionality and throughput are rising permanently. Furthermore, telecommunication carriers have different and changing requirements towards Access Network equipment. They are thus demanding a great deal of flexibility in IP-DSLAMS. To satisfy these various needs, highly flexible and particularly high performing...
In modern networks, the requirements towards network equipment rise together with the bandwidth. Customers and Internet service providers ask for more and more services like Voice-over-IP, IP-TV, and data services with a dependable quality. To satisfy these demands, the requirements towards packet classification as key functionality in network equipment, e.g., routers become overwhelming. We developed...
Today, an increasing number of customers subscribes for a high bandwidth Internet access. But not only communication speed is demanded. Quality-of-service moves more and more into the customers' focus. Both carriers and Internet Service Providers (ISPs) have increasing requirements derived from new services they want to offer to their customers. We present a new hardware solution is presented, which...
