Fast Firewall Implementations for Software and Hardware-Based Routers
Routers must perform packet classification at high speeds to efficiently implement functions such as firewalls and diffserv. Classification can be based on an arbitrary number of fields in the packet header. Performing classification quickly on an arbitrary number of fields is known to be difficult, and has poor worst-case complexity. In this paper, we re-examine two basic mechanisms that have ...
متن کاملFast Firewall Implementations for Software-based Routers
Routers must perform packet classi cation at high speeds to e ciently implement functions such as rewalls. The classi cation can be based on an arbitrary number of pre x and range elds in the packet header. The classi cation required for rewalls is beyond the capabilities o ered by standard Operating System classi ers such as BPF [12], DPF [7], PathFinder [1] and others. In fact, there are theo...
متن کاملSoftware and Hardware Implementations of Stereo Matching
Stereo matching is one of the key technologies in stereo vision system due to its ultra high data bandwidth requirement, heavy memory accessing and algorithm complexity. To speed up stereo matching, various algorithms are implemented by different software and hardware processing methods. This paper presents a survey of stereo matching software and hardware implementation research status based o...
متن کاملHardware-Assisted Design for Fast Packet Forwarding in Parallel Routers
A hardware-assisted design, dubbed cache-oriented multistage structure (COMS), is proposed for fast packet forwarding. COMS incorporates small on-chip cache memory in its constituent switching elements (SE’s) for a parallel router to interconnect its line cards (LC’s) and forwarding engines (FE’s, where table lookups are performed). Each lookup result in COMS is cached in a series of SE’s betwe...
متن کاملFast Software Implementations of SC2000
The block cipher SC2000 was recently proposed by a research group of Fujitsu Laboratories as a candidate cipher for the CRYPTREC and NESSIE projects. The cipher was designed so that it would be highly flexible and fast on many platforms. In this paper we show that the cipher is really fast on the Pentium III and AMD platforms: Our C implementation of SC2000 on Pentium III is only second to the ...
