System and methods are provided for providing modular control of network data packet handling and configurations. In one aspect, a storage-to-network mapping data structure is provided that can translate network connection parameters into high level, searchable concepts. In turn, these searchable concepts can be used by one or more modular software-defined storage applications to provide rules for network traffic handling that can then be merged into a dataplane forwarding data structure for implementation by a dataplane forwarder.

Systems and methods for defining storage

A network appliance is virtually inserted in a data path within a network. Packet data that matches a criteria is intercepted at a logical point within the data path. The intercepted packet data is forwarded to an application running on the virtually inserted network appliance.

Virtual insertion into a network

Methods and systems for optimizing data structures to efficiently control network data transfers are provided. For example, the method includes determining common key type sets from a plurality of network processing rules; creating one or more hash data structures using the most common key type sets; programming network processing rules that use the most common key type sets into the one or more hash data structures; programming remaining network processing rules into a content addressable memory (CAM); and using the one or more hash data structures and the CAM to find an appropriate network processing rule to process a network packet.

Methods and systems for network devices and associated network transmissions

Systems, devices, and methods for traffic management are provided. An example of a method for traffic management includes receiving a number of policies for data traffic redirectionin a data networkand authorizing a subset of the number of policies based upon matching a plurality of authorization rulessaved in the data network, for example, in a management tooland/or a network device

Systems, devices, and methods for traffic management

A method of transmitting an upstream communication packet from a distributed trunk (DT) switch is described. The method comprises receiving a packet from a device connected to a DT port of the DT switch; and transmitting the received packet via a non-DT port of the DT switch if the DT switch is the owner of the device and transmitting the received packet via a DT interconnect (DTI) port of the DT switch if the DT switch is not the owner of the device.

Transmitting a packet from a distributed trunk switch

A method of selective direct memory access (DMA) in a computer system having a network interface card (NIC), a processor subsystem, and a memory accessible to the subsystem, including the steps of the NIC receiving a plurality of packets from an external source; the NIC decoding a portion of each packet and determining whether the packet should be accepted by the computer system based on a predefined rule; and if the packet is accepted, selectively truncating the packet based on the predefined rule, and storing the truncated packet in the memory.

System and method for selective direct memory access

In one embodiment of the invention, a method for prioritizing network packets, includes: comparing a packet with at least one copy rule; and if the packet matches the copy rule, then buffering the packet in a queue. The method further includes: processing the packet after buffering the packet in the queue.

Prioritization of network traffic sent to a processor by using packet importance

A method and system for initiating selective flow control within a network multiplexer. Each port of a network multiplexer is associated with high and low threshold values, as well as a list of indications of ports that have requested the port to initiate flow control and a list of indications of ports which the port has requested to initiate flow control. A port that, by queuing a message descriptor to the transmit queue of a destination port, causes the number of message descriptors queued to the transmit queue of a destination port to equal or exceed its high threshold, is flow controlled by the destination port. When the number of message descriptors queued to the transmit queue of a destination port that previously equaled or exceeded the high threshold falls below the low threshold, all ports flow controlled by the destination ports are released from flow control.

Automatic load-balancing provides a decision-making process that includes intelligent automatic detection of when a given load-balancing activation currently would not be beneficial, thereby keeping the user's network from being unnecessarily disturbed when no real benefit would be gained; a process to undo a prior load-balancing that can be activated when users have accidentally selected a feature which could substantially change their network configurations; and an extensive intelligent distribution algorithm that improves the network load by moving the right nodes to new segments.

Method and apparatus for automatic load-balancing on a multi-segment network

In an embodiment of the invention, a method and apparatus for hardware throttling of network traffic, includes: receiving a packet; and preventing the packet from being copied, based on a rate field value associated with a new address in the packet information in the packet. The packet is not copied even if a copy rule is triggered.

Hardware throttling of network traffic sent to a processor based on new address rates

A method controls access of a user to a network including a plurality of hosts coupled together through a network switch. The method includes storing in the network switch an enhanced access control list containing data related to at least one of user names, DNS names, domain names, and physical addresses. A dynamic access control list is generated from the enhanced access control list, with the dynamic access control list containing a plurality of IP addresses that restrict access of the user to the network.
