20120002679 | PACKET FILTERING - Ingress and egress port packets for a connection between a first node and second node are mirrored to a mirroring port on a network switch. A count of ingress and egress port packets associated with a handshake process is determined. Duplicate mirrored packets associated with the connection are filtered based at least in part on the count. | 01-05-2012 |
20120084605 | REPLAYING CAPTURED NETWORK TRAFFIC - Systems, methods, and machine readable and executable instructions are provided for replaying captured network traffic. A method for replaying captured network traffic can include replaying multiple captured network traffic files simultaneously on the same network device, the captured network traffic files including original network traffic captured from N original connections between C original clients and S original servers. During replaying, rewriting IF addresses and/or port number information of data packets comprising the original network traffic to reflect test network traffic from M test connections between X test clients and Y test servers, where at least X is different than C or Y is different than S. The method further includes modifying checksums, during replaying, to correct values corresponding to the rewritten IF addresses and port number information. N, C, S, M, X, and Y are positive integers. | 04-05-2012 |
20120198047 | METHOD AND SYSTEM FOR DETERMINING RESPONSE TIME OF A SERVER - A method for determining a response time of a server may include monitoring communications to and from the server to detect a client request to the server. The method may also include detecting in the monitored communications at least one trigger signal associated with the client request. The method may further include determining a response time of the server to be the time difference between a time at which said at least one trigger signal was fully received and a beginning time of transmission of a final server response from the server, disregarding transmission periods and periods during which the client request is not processed by the server. A computer readable medium and system for determining a response time of a server are also disclosed. | 08-02-2012 |
20120198048 | IDENTIFYING REMOTE MACHINE OPERATING SYSTEM - A method for discovering an operating system of a remote machine includes monitoring network communications to detect a plurality of data packets that were generated by the remote machine. The contents of each detected data packet are read so as to extract a packet signature of each detected data packet. Each packet signature is compared with at least one signature of a database of signatures in order to determine a similarity between each packet signature and the signature from the database. A confidence level for at least one candidate operating system is calculated based on the determined similarities. A candidate operating system is selected based on the confidence level for that operating system. Relating computer program product and data processing system are also disclosed. | 08-02-2012 |
20120311129 | IDENTIFYING A DIFFERENCE IN APPLICATIOIN PERFORMANCE - A method for identifying a difference in application performance includes identifying first recorded statistics pertaining to traffic of an application sniffed during a first period prior to an application change. Subsequent to the application change, causing a collection, at the node, of the application's traffic during a second period and recording second statistics pertaining to that traffic. An evaluation is generated from a comparison of the first statistics with the second statistics. The evaluation indicates a difference in application performance following the change. | 12-06-2012 |
20130272301 | DETERMINING A MAXIMAL SIZE OF PACKETS - Packets from a first network entity to a second network entity are received. A maximal size of packets from the second network entity to the first network entity is determined based on information in the received packets. | 10-17-2013 |
20140059202 | DETERMINING THE TYPE OF A NETWORK TIER - Examples disclosed herein relate to determining the type of a network tier. Examples include determining that a target network tier is a forwarding type network tier if a protocol of communications between the target network tier and a source network resource is the same as a protocol of communications between the target network tier and a backend network tier. Examples further include comparing select content of communications between the target and backend network tiers to select content of communications between the target network tier and the source networking resource, if the protocols are the same. | 02-27-2014 |
20140207935 | SIMULATING REAL USER ISSUES IN SUPPORT ENVIRONMENTS - Methods, systems, and computer-readable and executable instructions are provided for simulating real user issues in support environments. Simulating real user issues in support environments can include providing stored data related to a real user issue associated with an application to a support device having the ability to modify the application, the stored data can include network traffic associated with a user device in a live environment and inputs provided via the user device. Simulating real user issues in support environments can include causing the support device to simulate the real user issue using the stored data. | 07-24-2014 |
