International Classification:

G06F 15/16

US Classification:

709230, 709227, 709238, 370352, 714 4

Abstract:

A system for connection failover using redirection includes a primary server comprising a primary connection failover driver (CFD), a shadow server comprising a shadow CFD, and a client. The primary and shadow servers and the client are coupled via a network. The primary server and the client are configured to cooperate to establish a network connection. The primary CFD is configured to redirect a first message packet, targeted for transmission to the client over the network connection, to the shadow server. The shadow CFD is configured to copy contents of the first message packet into a log, and forward the first message packet to the client after the contents have been copied.

G06F 11/00
G06F 12/00

US Classification:

718106, 714 15, 707202

Abstract:

A computer accessible medium may be encoded with instructions which, when executed: replicate a checkpoint segment from a first local storage of a first node to at least one other node; and load a copy of the checkpoint segment from the other node to a second local storage of a second node. The checkpoint segment is stored into the first local storage by an application, and comprises a state of the application. The copy of the checkpoint segment is loaded into a second local storage responsive to a request from the second node to load the copy. The second node is to execute the application. In some embodiments, the copy of the checkpoint segment may also be loaded into a global storage.

Abstract:

Various methods and systems for maintaining a communication protocol connection during a failover are disclosed. One method involves obtaining a first value of a parameter associated with a communication protocol connection between a primary node and a client and sending a flow control message to the client, in response to detecting that the primary node is failed. The flow control message includes the parameter.

US Classification:

709217, 709227

Abstract:

Various methods and systems for ending a communication protocol connection in response to detecting the failure of a cluster node are disclosed. One method involves detecting a failed node within a cluster. The failed node communicates with a client via a communication protocol connection. In response to detecting the failed node, a communication protocol message is sent to the client. Receipt of the communication protocol message causes the client to terminate the communication protocol connection.

Abstract:

Analyzing data on a network. A method of analyzing data on a network is disclosed. The method includes capturing network traffic on the network during a period of time where the network traffic is captured as raw data into data blocks. The data blocks are streamed to a mass storage. The data blocks are organized into logical blocks on the mass storage. A set of data points are compiled. The data points are useful for defining information about the logical blocks. The data points include an offset defining a number of bytes into the captured data and datum headers including the number of frames into a logical block, number of bytes contained in the logical block and clock ticks since the initiation of capturing.
