摘要： A method is disclosed for implementing and reporting network measurements between a source of probe packets and an element, such as a router. The invention exploits commonly implemented features on commercial elements. By exploiting these features, the expense of deploying special purpose measurement devices can be avoided. In one aspect of the invention, a plurality of probe packets is transmitted in a packet network with each of the probe packets having the same key and the same aggregation characteristic. A report is then received from an instructionless element regarding the plurality of probe packets, thereby enabling measurement of a parameter of the packet network.

摘要： A method for balancing traffic across paths connecting a network to the Internet using a fractional allocation strategy for distributing the traffic from a congested selected path. The strategy includes: (a) associating the paths j with a counter i; (b) calculating the total initial selected path overload; (c) calculating the selected path load, wherein the load is equal to the initial selected path overload less the sum of the low capacity boundary for i path(s); (d) calculating the portion of the traffic on the selected path to be distributed using a bi-sectional search strategy; (e) distributing a portion of the traffic on the selected path to the other paths; and (f) stopping if there are no more paths (i=j), otherwise increasing the numerical value of the counter by one (1) and go to step (c).

摘要： A facility for impersonating a number of iSCSI initiators within a IP-based Storage Area Network (SAN) is provided. In some embodiments, the facility receives iSCSI PDUs from a plurality of iSCSI devices. Each iSCSI PDU includes a SCSI command, an IP address of the initiator from which it was received, and an indication of a target storage device to which the iSCSI PDU is addressed. The facility maps IP address of the initiator from which the iSCSI PDU was received to a globally unique IP address and sends the iSCSI PDU to the indicated target storage device. When a response to the iSCSI PDU is received, the facility maps the globally unique IP address to the IP address of the initiator from which the iSCSI PDU was received and forwards the response to the initiator. In some embodiments, the facility is transparent to the iSCSI initiators.
