Techniques are provided for allocating hardware resources for an equal-cost multi-path (ECMP) group based on information about the network architecture. A table in memory may include a plurality of entries. Each entry may include interface set and a number of interfaces. Each interface set may represent a list of interfaces for the network device for a given network connection. The network device may receive a list of interfaces for allocating resource for an EMCP group. The network device may select an entry from the table by identifying an interface set that includes all of the interfaces for the ECMP group. The network device may determine a size of the ECMP group using a number of interfaces for the identified interface set from the entry from the table and allocate hardware resources (e.g., memory) for the ECMP group based on the determined size of the ECMP group.

A first switch in a MPLS network receives a plurality of packets that are part of a pair of flows. The first switch performs a packet prediction learning algorithm on the first plurality of packets and generates packet prediction information that is communicated to a second switch within the MPLS network utilizing an Operations, Administration, and Maintenance (OAM) packet (message). In a first example, the first switch communicates a packet prediction information notification to a Network Operations Center (NOC) that in response communicates a packet prediction control signal to the second switch. In a second example, the first switch does not communicate a packet prediction information notification. In the first example, the second switch utilizes the packet prediction control signal to determine if the packet prediction information is to be utilized. In the second example, second switch independently determines if the packet prediction information is to be used.

A network device includes (i) a software forwarding engine, and (ii) a hardware forwarding engine, wherein the software forwarding engine is implemented using a processor executing machine readable instructions. The network device analyzes a header of a received packet to determine i) whether the received packet belongs to any flows of packets already known to the network device, and ii) a packet type of the received packet. The network device selects one of the software forwarding engine or the hardware forwarding engine to process the received packet based on i) whether the received packet belongs to any flows of packets already known to the network device, and ii) the determined packet type, including selecting the software forwarding engine when it is determined that the received packet does not belong to any flow of packets already known to the network device.

A system provisions global logical entities that facilitate the operation of logical networks that span two or more datacenters. These global logical entities include global logical switches that provide L2 switching as well as global routers that provide L3 routing among network nodes in multiple datacenters. The global logical entities operate along side local logical entities that are for operating logical networks that are local within a datacenter.

A computer-implemented method of generating an integrated circuit design comprises: using a computer, detecting communication paths between data handling nodes, the data handling nodes comprising data source nodes, data sink nodes and data routing nodes operating according to respective power domains, clock domains and data traffic parameters, in a network of the data handling nodes; using the computer, for a given communication path in a direction of data flow from a data source node to a data sink node, for each given data routing node in the given communication path to which data is communicated in the direction of data flow by a set of one or more other data handling nodes, to perform the following steps: (i) detecting a power domain and data traffic parameters of each data handling node of the set of one or more other data handling nodes communicating data to said each given data routing node; (ii) assigning a power domain to said each given data routing node in dependence upon the detected power domains and the detected data traffic parameters of the set of one or more other data handling nodes; and (iii) assigning a clock domain to said each given data routing node, from a set of one or more candidate clock domains applicable to the assigned power domain, so that said each given data routing node, operating in the assigned clock domain, provides data routing according to the detected data traffic parameters of at least those of the set of one or more other data handling nodes operating according to the assigned power domain of said each given data routing node.

Systems, methods, and computer-readable media for managing service calls over a network may include a signal routing engine with a maintained forwarding table for various network functions and micro-services in a services back end for the network. The signal routing engine can include a call conversion service for converting REST API calls to an internal network call protocol for increasing network function processing speeds, decreasing bandwidth usage, and improving network responsiveness and manageability.

The embodiments described herein provide a data transmission system comprising a plurality of video routers, a supervisory system for transmitting one or more router configuration signals to one or more video routers, and a control communication network for coupling the plurality of video routers and the supervisory system. Each router in the system comprises a backplane including a plurality of backplane connections, at least one line card and at least one fabric card. Each line card comprises a plurality of input ports and output ports where each input and output port is coupled to a respective external signal through the backplane. Each line card further comprises a line card cross-point switch having a plurality of input switch terminals and a plurality of output switch terminals. Each fabric card comprises a fabric card cross-point switch having a plurality of input switch terminal and a plurality of output switch terminals. Furthermore, each line card and each fabric card comprises a card controller where the card controller selectively couples one or more input switch terminals of a cross-point switch to the output switch terminals of that cross-point switch. The cross-point switches being manipulated by the card controller may belong to one or more different cards within the same video router.

A method for scheduling a meeting using an email client that is part of an email system includes receiving a request at the email client to schedule the meeting. The request may include an indication of the resources that are to be provided by a conferencing system for the meeting. The method also includes communicating the request to a conference bridge that is part of the conferencing system and receiving from the conference bridge an access code associated with the meeting. The method also includes appending the access code to a meeting invitation associated with the meeting and providing the meeting invitation to an email server that is part of the email system. The method also includes sending the meeting invitation to users invited to participate in the meeting.

In one embodiment, a first router determines whether an interface coupling the first router to one or more second routers is transit-only. When the interface is transit-only, the first router generates an Open Shortest Path First (OSPF) Link State Advertisement (LSA) that includes an address for the interface and a designated network mask. The designated network mask operates as a transit-only identification that indicates the address should not be installed in a Routing Information Base (RIB) upon receipt of the OSPF LSA at the one or more second routers. When the network is not transit-only, the first router generates an OSPF LSA that includes the address for the interface but does not include the designated network mask, to permit installation of the address in a RIB upon receipt of the OSPF LSA at the one or more second routers.
