Abstract: A memory cell having a memory cell state is disclosed. The memory cell state includes a memory unit configured to store a bit of data wherein the bit of data determines whether the memory cell state is a first state or a second state and a common state indicator line configured to indicate a common state associated with a group of memory cells. The memory cell state further comprises a logic circuit configured to compare the memory cell state to the common state and an output line is configured to indicate the result of the comparison. A method of identifying one or more minimum value elements in a set of elements is also disclosed. The method includes storing the values in a memory cell array having a plurality of sets of memory cells, each value being stored in a set of memory cells. The stored values are compared to a set of common state indicator lines configured to indicate the minimum value stored in the memory cell array.
Abstract: A system and method are disclosed for redirecting a connection from a first server having a first server IP address. Incoming SYN packets sent from a client are intercepted. The SYN packets have a destination IP address corresponding to the connection and the SYN packets are sent from the client for the purpose of establishing the connection, which is supported by the first server. The number of incoming SYN packets sent from the client to the first server is monitored and it is determined whether the number of unanswered SYN packets sent by the client to the first server exceeds a ditched connection threshold number of unanswered SYN packets. The destination IP address of intercepted incoming SYN packets is changed for the connection received after determining that the number of unanswered SYN requests sent by the client to the first server exceeds a ditched connection threshold number of unanswered SYN requests to the destination IP address of a second server.
