摘要： A computer-implemented method classifies a packet received from a network. The method comprises receiving the packet having header information and a rule-set that indicates a plurality of actions to perform on the packet. A geometric representation of the rule-set is constructed having a plurality of dimensions and rule boundaries. At least one rule boundary and dimension of the geometric representation is split to form a search structure having a plurality of nodes. Each node in the plurality of nodes is constrained to a predetermined memory threshold. The search structure is searched using the header information to obtain a rule in the rule-set that indicates an action to take on the packet.

摘要： In an example implementation, a method is provided. The method includes receiving at a switch a packet having a tuple, wherein the tuple comprises a plurality of fields, wherein the switch operates using a protocol that compares each one of the plurality of fields to a table of a plurality of tables in series. The switch compares the plurality of fields of the tuple to a single cache table instead of the plurality of tables in series. When a match is found, a plurality of actions associated with the plurality of fields of the tuple is accumulated. The plurality of actions is applied to the packet.

摘要： Methods, systems, and apparatus for selective MAC address learning are disclosed. In one aspect, multiple different packets are received by a telecommunications device. The multiple different packets include different source MAC addresses. For each of the multiple different packets, a distribution type is determined. The distribution type is one of a one-to-one distribution type or a one-to-many distribution type. Based on the determined distribution type of the particular packet, a forwarding table of the telecommunications device is selectively updated. When the particular packet has the one-to-many distribution type, a source MAC address that is included in the particular packet is not stored in the forwarding table. When the particular packet has the one-to-one distribution type, the source MAC address that is included in the particular packet is stored in the forwarding table.

摘要： Embodiments provide a TCAM-based access control list that supports disjunction operations in rules. A network frame is received. Embodiments determine set TCP flags of the network frame. Upon determining that the set TCP flags match a first entry in a numeric range table, bits of a search key corresponding to the first entry are updated. The search key accesses a second entry stored in a TCAM. The first entry further comprises an encode field to scan a TCP header of the network frame for set TCP flags, a first mask field to a condition corresponding to unset TCP flags to identify in the network frame, a second mask field to a condition corresponding to set TCP flags to identify in the network frame, and an operation field specifying a disjunction operation for comparing the set TCP flags with the first mask field and the second mask field.

摘要： Examples include a network device to filter a packet for a packet type. The network device includes a filter to receive the packet and to determine whether the packet is a defined packet type. The network device also includes a Bloom filter to receive the packet from the filter based on the determination that the packet is a defined packet type and to determine whether the packet is a matched packet or an unmatched packet. A processing resource of the network device may receive the packet from the Bloom filter based on the determination that the packet is a matched packet and to determine whether the packet is an exact match.

摘要： A method and apparatus for reducing dynamic power consumption in a multi-thread content-addressable memory is described. The apparatus includes a first input configured to receive a first virtual address corresponding to a first thread, a second input configured to receive a second virtual address corresponding to a second thread, a register bank including a plurality of registers each configured to store a binary word mapped to one of a plurality of physical addresses, a first comparator bank including a first plurality of comparators each coupled to an associated register of the plurality of registers in a fully-associative configuration, and a second comparator bank including a second plurality of comparators each coupled to an associated register of the plurality of registers in a fully-associative configuration. An input virtual address to each comparator bank maintains its previous value for when a corresponding thread is not selected.

摘要： A method, apparatus and computer program product for providing Virtual Routing and Forwarding (VRF) and gateway Media Access Controller (MAC) distribution is presented. At least one subnet associated with a Layer 2 Virtual Switching Network (L2VSN) is provided on a network device. A message is propagated to a distributed Datapath. Network devices install the message as a routable MAC address on the L2VSN for the Layer 3 Virtual Switching Network/Virtual Routing and Forwarding (L3VSN/VRF) associated with the message. Edge devices route packets on the L2VSN addressed to the gateway MAC address.

摘要： One embodiment provides a system that facilitates dynamic adjustment of forwarding information in a CCN. During operation, the system receives, by forwarding circuitry, an interest with a name that is a hierarchically structured variable length identifier which comprises contiguous name components ordered from a most general level to a most specific level. The system identifies in a first data structure an entry for one or more name components of the name, wherein the entry includes a list of outgoing interfaces associated with the one or more name components. The system determines network properties in response to forwarding the interest to a first interface of the list. The system reorders the list in order of priority based on the network properties, thereby facilitating the forwarding circuitry to dynamically adjust a likelihood of using a respective interface for forwarding interests associated with the one or more name components.
