Abstract:
A method for routing content, comprising receiving an interest packet from a first face, wherein the interest packet comprises a content name field populated with a first content name, a destination field, and a broadcast flag field set to broadcast, wherein the broadcast field indicates whether the first face has previously received a request having the first content name, and receiving a data packet from a second face, wherein the data packet comprises a content name field populated with a second content name, a source field populated with the identity of a source of data associated with the second content name, and a data field populated with the data associated with the second content name.
Abstract:
In general, this disclosure describes a high-level forwarding path description language (FPDL) for describing internal forwarding paths within a network device. The FPDL enables developers to create a template that describes a section of an internal forwarding path within the forwarding plane of a network device. The FPDL provides syntactical elements for specifying the allocation of forwarding path structures as well as enabling the run-time construction of internal forwarding paths to interconnect the forwarding path structures in a manner specific to packet, packet flow, and/or interface properties, for example. In conjunction with late binding techniques, whereby the control plane of the network device provides arguments to template parameters that drive allocation by the packet forwarding engines of forwarding path structures specified by the FPDL, the techniques provide control plane processes a unified interface with which to manage the operation of the packet forwarding engines.
Abstract:
Provided are computer program product, system, and method for determining whether a short or long message format is used to communicate zone information in a network. One large zone is implemented for end devices coupled to ports of data forwarders. A first formatted zoning distribution message is generated for the data forwarders identifying the data forwarder and ports on the data forwarders in the one large zone in response to determining that the data forwarder supports the short message format. A second formatted zoning distribution message is generated identifying the data forwarder, the ports on the data forwarders, and additional fields of information on the ports not included in the first formatted zoning distribution message in response to determining that the data forwarder does not support the short message format; and sending the generated first formatted or second formatted zoning distribution message to the data forwarder.
Abstract:
A method for communication between nodes (UR1; UR2; UC1-UC16) of a network, interconnected by a transmission channel and each identified by a node identification number in which at least one transmitter node emits at least one message to at least one message recipient node. The message comprises a description of a path (PH) between the transmitter node which emits the message and the message recipient node. The path is defined by the node that emits the message via a sequence of node identification numbers along the path itself.
Abstract:
Techniques are provided for packet routing in a distributed network switch. The distributed network switch includes multiple switch modules operatively connected to one another, and each switch module includes multiple bridge elements and a management controller. In one embodiment, a shared interface routing (SIR) framework is provided that includes an analysis and bifurcation layer and at least one packet interface. A packet is received over a first logical network and via a physical port, the packet being destined for at least a first application executing on the management controller. The analysis and bifurcation layer analyzes the packet and sends the packet to the packet interface, which then routes the packet to the first application.
Abstract:
A system and method for routing communication in a communication platform that includes generating edge cost scores in the communication network; assigning distribution values within the network; setting a score tolerance; receiving a communication directive; performing network graph search to identify a selected route through a route selection process including considering cost score within the score tolerance and distributing selection of a route associated with the communication directive in accordance to the distribution values; and establishing a media route specified by the selected route.
Abstract:
To partition a distributed fabric system, at least one system port is allocated to each switching domain of multiple non-overlapping switching domains in a distributed fabric system. Multiple different look-up tables are produced, wherein each look-up table corresponds to a different switching domain of the multiple non-overlapping switching domains in the distributed fabric system. Each system port is associated with the look-up table of the multiple look-up tables that corresponds to the switching domain to which that system port is allocated. The look-up table associated with each system port has at least one table entry for each other system port allocated to the same switching domain as that system port.
Abstract:
MPLS segment routing is disclosed. In one embodiment, a first core router generates a first data structure that maps first portcodes to respective identities of first neighbor routers or respective first links, wherein the first portcodes identify respective first ports of the first core router, and wherein the first ports are coupled to the first neighbor routers, respectively, via the first links, respectively. The first core router generates and transmits a first link-state packet, wherein the first link-state packet comprises an identity of the first core router and the first data structure.
Abstract:
Techniques are described for implementing one or more logical routers within a single physical routing device. These logical routers, as referred to herein, are logically isolated in the sense that they achieve operational and organizational isolation within the routing device without requiring the use of additional or redundant hardware, e.g., additional hardware-based routing controllers. The routing device may, for example, include a computing platform, and a plurality of software process executing within the computing platform, wherein the software processes operate as logical routers. The routing device may include a forwarding component shared by the logical routers to forward network packets received from a network in accordance with the forwarding tables.
Abstract:
In an exemplary embodiment, a computer-implemented method includes providing a mapping between a set of two or more IP addresses and a set of two more servers. A weight recommendation for the servers is received, based at least in part on server data related to current states of the servers, where the weight recommendation represents a goal for distributing a plurality of transactions among the servers. The mapping is modified based at least in part on the weight recommendation. A transaction is received, directed toward a first IP address of the two or more IP addresses. The transaction is routed to a first server, of the two or more servers, associated with the first IP address according to the modified mapping.
