An apparatus for forwarding packets includes a packet processing pipeline having a processing unit that processes packets compliant with a recognized communication protocol. A first port coupled to the packet processing pipeline is configured to receive a packet that does not comply with the recognized communication protocol and has a header that conforms to a second communication protocol. A data extraction unit extracts first destination information from the header of the packet and, based on the first destination information, generates second destination information that conforms to the recognized communication protocol. The processing unit determines, based on the second destination information, an egress interface to which the packet is to be forwarded.

A server apparatus comprises a plurality of server on a chip (SoC) nodes interconnected to each other through a node interconnect fabric. Each one of the SoC nodes has respective memory resources integral therewith. Each one of the SoC nodes has information computing resources accessible by one or more data processing systems. Each one of the SoC nodes configured with memory access functionality enabling allocation of at least a portion of said memory resources thereof to one or more other ones of the SoC nodes and enabling allocation of at least a portion of said memory resources of one or more other ones of the SoC nodes thereto based on a workload thereof.

Systems, methods, and other embodiments associated with logically partitioned networking devices are described herein. One example method includes receiving a message from a common interface. The message comprises a logical partition header (LPH) and a network segmentation header (NSH). The LPH may be associated with a logical partition of a networking device. The NSH is associated with a grouping (e.g., segmentation) of networking devices. The example method may also include forwarding the message to the grouping of networking devices based, at least in part, on the NSH and a virtual route forwarding (VRF) table. Forwarding the message to the logical partition of the networking device based, at least in part, on the LPH.

A multi-protocol personality module enabling load/store from remote memory, remote Direct memory Access (DMA) transactions, and remote interrupts, which permits enhanced performance, power utilization and functionality. In one form, the module is used as a node in a network fabric and adds a routing header to packets entering the fabric, maintains the routing header for efficient node-to-node transport, and strips the header when the packet leaves the fabric. In particular, a remote bus personality component is described. Several use cases of the Remote Bus Fabric Personality Module are disclosed: 1) memory sharing across a fabric connected set of servers; 2) the ability to access physically remote Input Output (I/O) devices across this fabric of connected servers; and 3) the sharing of such physically remote I/O devices, such as storage peripherals, by multiple fabric connected servers.

Systems and techniques for processing and forwarding packets are described. Some embodiments provide a system (e.g., a switch) which determines an internal virtual network identifier and/or an internal policy identifier for a packet based on a port on which the packet was received and/or one or more fields in the packet. The system can then process and forward the packet based on the internal virtual network identifier and/or internal policy identifier. In some embodiments, the system encapsulates the packet in a TRILL (Transparent Interconnection of Lots of Links) packet by adding a TRILL header to the packet. In some embodiments, the scope of an internal virtual network identifier and/or an internal policy identifier may not extend beyond a switch or a module within a switch.

A network data monitoring device provides for the flexible, programmable port-to-multi-port steering of data packet traffic between network port pairs, with tap data streams being directed to any of a plurality of monitor ports. The network data monitoring device is constructed utilizing one or more switching integrated circuits programmed to disable layer-2 routing and impose port-to-multiport data packet steering. Physical layer protocol encoding/decoding circuits enable connectivity to physical network media connectors though a system of fail-safe relays. A system controller, preferably implemented by a microprocessor, is connected to all switching integrated circuits and relays for configuration, status and control. Hardware-based logic selectively in complement to the switching integrated circuits provides for the programmable filtering, modification and programmable steering of data packets through the device.

Methods, systems, computer-readable media, and devices for aggregating sets of received captured network traffic by a network captured traffic distribution device communicatively coupled to a plurality of network captured network traffic distribution devices arranged in a stacked topology are described. Systems for aggregating captured network traffic may include a source of captured network traffic, a plurality of stacked network captured traffic distribution devices arranged in a stacked topology such that each network captured traffic distribution device is communicatively coupled via a communication link with at least one additional stacked network captured traffic distribution device, and an external device. In some embodiments, one or more of the stacked network captured traffic distribution devices, source, and/or external device may operate at locations that are geographically disperse from one another.

Apparatus and system for aggregating captured network traffic

A network traffic distribution device (e.g., a network tap or similar device) is configured to receive and analyze captured network traffic data packets that include tunneling IDs (e.g., GTP tunneling IDs) and, based on that analysis, to distribute those data packets in such a way that data packets with the same tunneling IDs are distributed to a common egress port of the network traffic distribution device. In some cases, each flow of data packets with a common tunneling ID is sent to a unique external device, while in other cases, two or more traffic flows, each with packets having respective, common tunneling IDs may be provided to the same external device, either via a common egress port of the network traffic monitoring device or via separate egress ports thereof.

Methods, systems, computer-readable media, and devices for automatically configuring a network captured traffic distribution device communicatively coupled to a stacked topology of network captured traffic distribution devices are described. The automatic configuration may include an exchange of configuration information between a first and second network captured traffic distribution device included in a stacked topology. The configuration information of a network captured traffic distribution device may also be automatically updated when, for example, a change is detected in the stacked topology or on a periodic or as needed basis.

Auto-configuration of network captured traffic device

Systems, devices, and methods for finding a captured data packet including a data pattern of interest and data packets associated with the found data packet are herein provided. A traffic flow of captured data packets may be received by a network captured traffic distribution device and may be duplicated. A traffic flow of captured data packets may be scanned for data packets including a data pattern of interest and identifying information may be determined for any found data packets. A duplicate traffic flow of captured data packets may also be scanned for data packets with identifying information that matches a found data packet. An egress port for the found data packet may be determined and both the found data packet and any data packets with identifying information matching found data packet might be transmitted to the determined egress port.
