Abstract: The solution of the present invention provides systems and methods for encoding information into an Internet Protocol identification field (IPID) of an IP layer header of a network packet in a manner acceptable to many or all of the network devices that encounter the encoded packet. In one embodiment, the solution described herein encodes the IP identification field of the IPID header with information to be communicated between devices. Appliances may use the encoded IP field as a signal or a means for a low-bandwidth subcarrier of data between the appliances that is transparent to any intervening network equipment. For example, the encoded field may be used to announce or probe the presence of a device, a functionality or capability of device or to indicate a type or speed of a network connection of a port on a device.

Abstract: A plurality of memory devices of mixed type (e.g., DRAMs, SRAMs, MRAMs, and NAND-, NOR- and AND-type Flash memories) are serially interconnected. Each device has device type information on its device type. A specific device type (DT) and a device identifier (ID) contained in a serial input (SI) as a packet are fed to one device of the serial interconnection. The device determines whether the fed DT matches the DT of the device. In a case of match, a calculator included in the device performs calculation to generate an ID for another device and the fed ID is latched in a register of the device. In a case of no-match, the ID generation is skipped and no ID is generated for another device. The DT is combined with the generated or the received ID depending on the device type match determination. The combined DT and ID is as a packet transferred to a next device. Such a device type match determination and ID generation or skip are performed in all devices of the several interconnection.

A second UDP packet is sent to the port with an Internet Protocol (IP) timestamp option set in an IP header and a response evoked by the second sent UDP packet is monitored. The operating system is identified at least partially based on the responses to the first and second sent UDP packets.

Abstract: Systems and methods are provided for an optimized mobile-IPv6 encapsulation. A mobile node sends packets to a correspondent node by encapsulating a packet using an IPv6 routing extension header, and reverse tunneling the packet to a home agent. The home agent modifies the packet and forwards it to the correspondent node. When the correspondent node sends packets to the mobile node's home address, the home agent intercepts the packet, encapsulates the packet with an IPv6 routing extension header, and tunnels the packet to the mobile node. Consequently, because packets are tunneled using IPv6 routing extension headers, the amount of overhead in each encapsulated packet is reduced, thus increasing the available bandwidth in a network.

Abstract: A technique is disclosed for controlling data packet transmissions from a server to a client having a client buffer in accordance with a waiting mode and a dynamic mode. The waiting mode is performed before packets containing data encoded subject to a current bit rate have reached the client buffer; the dynamic mode is performed otherwise. In the waiting mode, down-switches to lower bit rates are allowed but up-switches to higher bit rates are disabled. In the dynamic mode, up-switches and down-switches are both allowed, with adjustments in the bit rate of packets controlled based, in part, on the amount of data contained within the client buffer when packets containing data encoded subject to the current bit rate first reached the client buffer. The two modes help avoid unnecessary rate switches.

Abstract: Sequences of items may be maintained using ordered locks. These items may correspond to anything, but using ordered locks to maintain sequences of packets, especially for maintaining requisite packet orderings when distributing packets to be processed to different packet processing engines, may be particularly useful. For example, in response to a particular packet processing engine completing processing of a particular packet, a gather instruction is attached to the particular identifier of a particular ordered lock associated with the particular packet. If no longer needed for further processing, the packet processing engine is immediately released to be able to process another packet or perform another function. The gather instruction is typically performed in response to the particular ordered lock being acquired by the particular identifier, with the gather instruction causing the processed particular packet to be sent.

Abstract: A method and system for accessing a remote real communication port (“COM port”) from a server blade in a server blade chassis by creating a virtual COM port in the server blade. A basic input/output system (BIOS) controller monitors an internal COM port in the server blade for communication traffic.

The virtual USB COM port directs the communication traffic to an internal universal serial bus (USB) device in the server blade. The USB device then forwards the traffic to an Ethernet media access controller (MAC) input/output (I/O) on a sideband channel to a remote system, which passes the communication traffic to a real COM port in the remote system.
