I am trying to replicate part of the EuropeanOptionExample using my date. I have a data.frame containing all my inputs atm.vols<-subset(data.vols,moneyness==min); #Some days have the abs(moneyness) exactly between two strike prices, #Traders will alway price an option at the higher vol when selling it, so we will too.

Hi, I use the patch (http://ace-host.stuart.id.au/russell/files/tc/tc-atm/) for accurate the packet scheduling on ATM/ADSL link and i think I''ve found a bug. I tried to write to the author but he didn''t answer me. I work on a Linux 2.6.17 with the iproute2-2.6.18-061002 package. I change the type of the cell_align char to short of the struct tc_ratespec in the file pkt_sched.h

I have been trying to optimise my ADSL connections for VOIP. Funny things were happening - for example increasing the ping packet size by 50% had no effect, but then adding one byte had a major effect. It took me a while to figure out that I was seeing the effects of the fixed ATM cell size. This is probably obvious to some of you. For the rest: ADSL uses ATM as its transport. An ATM

I have a situation where this is fine: > if (length(x)>15) { clever <- rr.ATM(x, maxtrim=7) } else { clever <- rr.ATM(x) } > clever $ATM [1] 1848.929 $sigma [1] 1.613415 $trim [1] 0 $lo [1] 1845.714 $hi [1] 1852.143 But this variant, using ifelse(), breaks: > clever <- ifelse(length(x)>15, rr.ATM(x, maxtrim=7), rr.ATM(x))

I had originally mentioned this only to 2 people, which was Jordan K. Hubbard and Paul Henning-Kemp, but since I have received a lot of queries on this, I thought I might as well post it on the FreeBSD announce groups. Included below is a posting done on the Linux-atm mailing group, by Pragnesh Sampat. I have just adapted for FreeBSD. RV -------------------------- Announcement

Does anyone here have experience with an ATM connection from their ISP running into a linux based router? We have a DS3 circuit for which we we thought we could use an SBE wanpci-1t3 card. The isp verified the card would work with their network, but apparantly didn''t cross check the particular circuit they were providing us. Is it possible to do the IP packet <-> ATM cell

Hi all, I patch my kernel (2.6.17) and my tc (iproute2-2.6.18-061002) utilitie for an accurate packet scheduling on an ATM link. I configure my HTB hierarchy on the upload of the link and try with differents flows. It works correctly but in some of case I lose about 50% of my bandwith. I use the overhead (42) configuration for my link (PPPoE, VC/LLC) indicate in the documentation. My question

I know there is that handy patch available to very efficiently use ATM bandwidth, but I was wondering what the best values to use with a non-patched iproute2 would be. Anyone here care to check my logic in coming up with these numbers and perhaps suggest better values? My transmit speed is 768kbps per ADSL line (I have two). This is the HTB shaping I do on the interface (logic used for this

The Applied Research Lab (ARL) of Washington University and the ATOMIC-2 Project at USC/ISI are pleased to announce the availability of a BSD device driver for the Adaptec 590x series of PCI ATM host adaptors (eg ANA-5940) Written by Chuck Cranor of Washington University's ARL (chuck@ccrc.wustl.edu), the "MIDWAY" ATM device driver originally supported Efficient Network's

Hi all, we have a very large customer (90'000 PCs) worldwide that has problems with a Samba server. Here are the details : platform : IBM 4-cpu server runing AIX 4.3 Samba : 2.2.7a compiled with gcc 2.95.3 clients : about 100-200, worldwide network : ATM, at least for the server (I don't have more details, sorry) samba config : pretty straightforward, security=server (might be

Hi there.I''m Brenda from the Australia,I wanna work on a project relating to VOIP QoS.I wanna evaluate IP over ATM against IP over Ethernet on the following parameters relating to voice and video traffic; bandwidth consumption packet loss packet delay(latency) jitter traffic thoroughput Is this project feasible?Can I use NS to simulate the models?I hope you reply.Thanks. Best regards.

Hi, I am trying to plot multiple lines on a graph. The function is particularly simple: sigma<-function(lambda) atm-2*rr*(lambda-0.5)+16*str*(lambda-0.5)^2 which uses the variables atm, rr and str... I define these as such: atm<-0.4 rr<-0.2 str<-0.1 and this plots fine: plot(seq(0.01,0.99,0.01),sigma(seq(0.01,0.99,0.01)),ylim=c(0,1)) Now, I want to plot the same function for

Is it possible to dynamically do bandwidh reservation? That is, I want to limit the traffic to 50% for upload and download, but if there aren''t onbound traffic, who is doing a download will get 100% of bandwidh and if there aren''t inbound traffic, who is doing a upload will get 100%, but if there are both inbound and outbount traffic, each one get limited to 50%. I think this

It seems Andreas Klauer''s fairnat has experimental support for using HTB''s MPU and overhead options. fairnat.config: # Use MPU for HTB. From the LARTC Howto on MPU: # "A zero-sized packet does not use zero bandwidth. For ethernet, no packet # uses less than 64 bytes. The Minimum Packet Unit determines the minimal # token usage for a packet." HTB_MPU=0 # HTB_MPU=64

I have read the thread at http://mailman.ds9a.nl/pipermail/lartc/2006q1/018287.html and still don''t know how to fix this problem. It appears alot of work has gone into it but the HOWTO is so out of date it doesn''t even begin to addresses this method. So here are my questions 1. what is the current state of these patches? are they in a specific version? do i have to patch myself?

Hello, I'm having problems using SAMBA servers within an IP over ATM network. I'm using experimental IP addresses (net 192.168.28.0), Linux servers with the 2.2.1 kernel version and RedHat 5.2, Win95 and WinNt 4.0 client machines. The problem is, through Ethernet everything works the way it should. Using ATM and keeping the Ethernet cables connected somehow the data flows through the ATM
