Using select and poll and SIGIO and which is faster and timeouts select and/or poll and/or SIGIO vs forking SIGIO The two types of sigio (one argument and three argument) Multiple sigio's are combined (ick!) sigio and the relationship to threading Threads The thread calls (fork, wait, etc) Locking when howto Thread-safety which calls are or not How to get thread safety in your code Threads compared to forking IPv6 (see http://euclid.nmu.edu/~randy/Classes/CS442/Notes/IPv6/Test_Review.html) NFS statelessness and idempotency NFS cookies NFS and getting a file (which commands are needed) caching in NFS permission checking Handling failures SMB SMB and getting a file (which commands are needed) caching in SMB permission checking Handling failures Transport Schemes Ping Pong Go Back N Selective Repeat Use of NACKs Routing Djikstra Ford BGP Autonimous Systems Cheating to force others to not send traffic down a link Which are perfect Which count to infinity How to stop counting to infinity How many rounds to stableize PCAP The library Filtering Reading those dang header charts Peer-2-Peer Computing checksums Structured networks like Kazaa Supernodes Amorphous networks like Gnutella Networks that hide identity RMI Stubs and skels Serializablity Callbacks rmiregistry speed compared to networking with writes/reads flexibility comared to networing with writes and reads.
