Hi, I am a bit lost on ideas for answering the following question Hamming's method of error correction can only detect and correct single bit errors. However, we saw that it requires 4 additional (redundant) bits to support the 7 data bits of each A...

Would discussing the use of concurrent servers, iterative servers and the use of inetd be sufficient?

The Network File System (NFS) employs Remote Procedure Calls (RPCs) over the User Datagram Protocol (UDP). With reference to traditional file-system semantics, what problems does this choice of interprocess communication scheme introduce? What solutions ...

For this point in lecture 11 The smurf attack has 3 types of victims the single destination victim of the attack, a network abused (temporarily) to amplify the attack, and (always) the host harboring the attacker. Could you please explain why the host ...

Develop an implementation in pseudo-code, with a syntax similar to C, Python, or Java, that simulates the behaviour of the 1-persistent CSMA CD protocol over 100Mbps Ethernet. The simulation should support N identical nodes, each wishing to transmit ...

Is storing the sequence of ports used only in the udp packet allowed? and then at each node sending it to the next neighbour in the journey, as opposed to flooding the network again?

I'm flooding the network with a udp packet that contains the original udp port it was sent from. Once a route has been found somewhere in the network, it can access this port and send it directly back. Is this allowed? or must it be forwarded back al...

My current implementation blocks new udp connections while waiting for acknowledgements from neighbouring hosts to come back for a specific frame. this will slow down response time, will this get marked down?

Are threads allowed within a station server process, ie to handle receiving and sending datagrams?

Hi, is there a maximum length of a station name? Thank you

no station server should ever contain all knowledge about the whole network, timetabling data, or network connections. Each station's timetabling data, recorded in one textfile for each station, may change at any time (for example, if a bus breaks do...

Hi Chris, hoping for clarification on the following dot point Ideally, the returned result will be the fastest journey - even if it leaves later or includes more segments (hops) than other journeys (but firstly, just report any any valid journey ) S...

Are CRCs and polynomial codes assessable topics for the mid-sem? Thank you
