Vijay You have got it wrong. Let me explain.
r 40.639943 _1_ AGT --- 1569 tcp 1032 [a2 1 2 800] ------ *[0:1 1:0 32 1] *[35 0] 2 0. Here above, r = received 40.639943 = time it was received _1_= receivind node number(means the packet was received at node 1) AGT = means transport layer(I think) 1569 = unique packet id(each packet has a unique id) tcp = Transmission Control Protocol 1032 = packet size a2 = packet lifetime(I think) 1 = MAC address of sender 2 = MAC address of receiver 800 = 802.11 wireless 0:1 = means node 0 (i.e. address is 0) and port is 1 of sender 1:0 = means node 1 (i.e. address is 1) and port is 0 of receiver 32 = TTL There are lot of books online, download them, they are free and look up 'Trace Format' Maruf ----- Original Message ----- From: Vijay Kumar c <[EMAIL PROTECTED]> Date: Wednesday, March 14, 2007 10:24 pm Subject: [ns] Urgent Help Needed:Wireless Trace Format To: [email protected] > Hi ns users, > > I am facing a problem in analysing the Wireless trace file format.I have > given the exanmple below and tried to explain my problem for which i > have > used *Bold Font* > > Example: > > r 40.639943 _1_ AGT --- 1569 tcp 1032 [a2 1 2 800] ------ *[0:1 1:0 > 32 1] *[35 > 0] 2 0. > > My problem is explained using the above trace line which i got as output > here the second square brackets which is shown in bold format which concern > the IP addresses of the source and destination , then the number 32 > in the > second square brackets which represent the ttl(Time to live) of the packet. > > I am not able to understand the IP addresses of source and destination > i.e0:1 and 1:0 wheather this denotes the mobile node id of the source > that is > 0:1 represents the source mobile id when the packet is transmitted from > mobile node 0 to mobile node1 and when the packet is recieved at the > destination the packet it is denoted as 1:0 which says that the > packet was > sent and recieved at the destination by mobile node1 which was sent from > mobile node 0. > > This is my observation and analysis .Kindly give your valuble suggestions > and comments so that i can correct myself if the observation is wrong. > > suggesstions and comments are most welcome > Reg: > Vijay
