| 20120036279 | DISTRIBUTED CONNECTIVITY VERIFICATION PROTOCOL REDUNDANCY - In one embodiment, a connectivity verification protocol (CVP) session for a particular virtual interface (VI) may operate on a particular group of two or more line cards (LCs) on a network device. The group of LCs may then transmit CVP session packets, at a reduced rate that is sufficient to maintain the CVP session based on a negotiated CVP full rate, onto the particular VI through ingress path processing on the network device. Ingress path processing, in particular, takes transmitted CVP session packets and egresses them onto an appropriate LC of the network device currently responsible for the VI egress. Also, in response to receiving CVP session packets for the VI on an LC of the network device currently responsible for the VI ingress, the receiving LC may forward the received CVP session packets to the particular corresponding group of LCs, which may then process the received CVP session packets. | 02-09-2012 |

| 20110154477 | DYNAMIC CONTENT-BASED ROUTING - Systems and methods for redirecting network traffic include a policy server configured to be in communication with a policy database and a client disposed on a remote device. The policy server is configured to receive an inquiry from the client regarding a universal resource locator (URL) request and, based on a policy obtained from the policy database, cause the client to control the remote device such that network traffic associated with the URL request is routed (tunneled) via a particular interface, e.g., a virtual private network (VPN) connection, when so required by the policy, and network traffic associated with the URL request is routed over a different VPN connection or a non-VPN connection when so required by the policy. | 06-23-2011 |
| 20110153862 | Sender-Specific Counter-Based Anti-Replay for Multicast Traffic - Techniques are provided for more robust counter-based anti-replay protection with respect to packets sent between network devices. A network device receives packets sent over a network from another network device. Each packet contains a source identifier that identifies a device that is the source of the packet, a destination identifier that identifies a device that is the intended destination of the packet, a sender identifier that identifies a network device that encrypted and sent the packet and a sequence number associated with the packet. The network device stores data indicating source identifier, destination identifier, sender identifier and sequence number for packets received over time. The network device rejects a newly received packet when it is determined that the sequence number of the newly received packet is less than the last sequence number stored for a matching packet flow (same source identifier, destination identifier and sender identifier) and falls outside of the counter-based window with respect to the last sequence number stored for the matching packet flow. | 06-23-2011 |
| 20110153780 | APPARATUS AND METHODS FOR HANDLING NETWORK FILE OPERATIONS OVER A FIBRE CHANNEL NETWORK - Disclosed are methods and apparatus for facilitating transmission of file access type messages over a Fibre Channel (FC) network. In one embodiment, at a file interposed access protocol layer of a file access client, a file access type operation is received from a file access type layer at the client device. The interposed layer may be interposed between an upper file access layer and an FC layer. The file access type operation specifies a request pertaining to file access. At the interposed file access protocol layer of the client, the file access type operation is modified into one or more sequence of operations so that the operations can be transmitted over an FC network. A sequence of operations are transmitted to an file access server over the FC network. | 06-23-2011 |
| 20110150466 | ENCAPSULATION SCHEME FOR OPTICAL OVER ETHERNET - According to one general aspect, a method may include receiving, from an optical transmitter, an optical signal that includes information. In some embodiments, the method may include encapsulating at least a portion of the received information into an Ethernet packet. In various embodiments, the method may include associating a control word with the Ethernet packet. In such an embodiment, the control word may include a status portion that indicates a status of at least a portion of the network including the networking apparatus, and an ordinal number configured to facilitate the re-construction of the information included by the optical signal. In various embodiments, the method may include transmitting the Ethernet packet to a networking apparatus. | 06-23-2011 |
| 20110145854 | SYSTEMS AND METHODS FOR DIGITAL PROGRAM INSERTION WITHIN SCRAMBLED CONTENT - Systems and methods for digital program insertion. Entitlement control messages (ECMs) may be sent over an out-of-band communication channel to a client device such that the ECMs are received proximate in time to splice points where, e.g., advertising is inserted into a scrambled program or when the scrambled program is to resume at the end of the ad or program insertion. The ECMs may be communicated over the out-of-band channel having a timing such that the client device can process the ECMs, extract a control word and begin descrambling of the scrambled program to provide near seamless splices. In some implementations, out-of-band bandwidth is conserved as the ECMs are sent a splice time, rather than continuously. | 06-16-2011 |
| 20110145832 | TECHNIQUES FOR ALLOCATING COMPUTING RESOURCES TO APPLICATIONS IN AN EMBEDDED SYSTEM - Techniques for allocating computing resources to tasks include receiving first data and second data. The first data indicates a limit for unblocked execution by a processor of a set of at least one task that includes instructions for the processor. The second data indicates a maximum use of the processor by the set. It is determined whether a particular set of at least one task has exceeded the limit for unblocked execution based on the first data. If it is determined that the particular set has exceeded the limit, then execution of the particular set by the processor is blocked for a yield time interval based on the second data. These techniques can guarantee that no time-critical tasks of an embedded system on a specific-purpose device are starved for processor time by tasks of foreign applications also executed by the processor. | 06-16-2011 |
