consider a client and server using an rpc mechanism that includes chana give a scenario involving server reboot in
suppose blast is used over a link with a 10 per-packet loss rate losses are independent events fragments that do arrive
both the blast and chan protocols have a mid fielda under what circumstances can these be equal for several packets in
suppose we were to implement remote file system mounting using an unreliable rpc protocol that offers zero-or-more
the tcp header does not have a bid field like chan does how does tcp protect itself against the crash-and-reboot

suppose a tcp message that contains 2048 bytes of data and 20 bytes of tcp header is passed to ip for delivery across
some signalling errors can cause entire ranges of bits in a packet to be overwritten by all 0s or all 1s suppose all

consult request for comments 793 to find out how tcp is supposed to respond if a fin or an rst arrives with a sequence
suppose that tcp is measuring rtts of 10 second with a mean deviation of 01 second suddenly the rtt jumps to 50 seconds
what is the justification for the exponential increase in timeout value proposed by karn and partridge why specifically
explain why time wait is a somewhat more serious problem if the server initiates the close than if the client does
suppose a client c repeatedly connects via tcp to a given port on a server s and that each time it is c that initiates
