International Classification:

H04L 12/26

US Classification:

370230

Abstract:

A method for configuring admission control of service instances in a network element may include: (i) reading a pre-determined maximum service-idle utilization of a processor approximately equal to maximum utilization of the processor in the absence of services executing on the processor; (ii) reading, for each particular service instance of a desired configuration of service instances, a pre-determined maximum utilization of the processor associated with the particular service instance; (iii) calculating an aggregate maximum utilization for the desired configuration, based on the pre-determined maximum service-idle utilization and the pre-determined maximum utilizations for each of the particular service instances; (iv) determining whether the aggregate maximum utilization is greater than a threshold maximum utilization for the processor; (v) allowing or denying the desired configuration based on the determination.

International Classification:

H04L 12/26

US Classification:

370235

Abstract:

According to one embodiment, a method may include receiving a frame via an ingress port of a network element. The method may also include assigning a virtual destination address to the frame of the traffic. The method may further include internally switching the frame within the network element based on the virtual destination address. The method may additionally include modifying the virtual destination address one or more times such that the virtual destination address is translated to an actual destination address identifying an actual egress port of the network element. Moreover, the method may include routing the frame to an egress port of the network element based on the actual destination address.

International Classification:

H04L 12/26

US Classification:

370235

Abstract:

According to one embodiment, a method may include assigning a virtual local area network (VLAN) ingress connection identifier (iXid) to a frame upon ingress. The method may also include classifying a traffic flow for which the frame is a part through ingress engines of the network element based on the iXid. The method may further include swapping the iXid for an egress connection identifier (eXid) in the frame. The method may additionally include policing or shaping the traffic flow based on at least one of the iXid and the eXid. Moreover, the method may include classifying the traffic flow through egress engines of the network element based on the eXid.

International Classification:

H04L 12/26

US Classification:

370235

Abstract:

According to one embodiment, methods and systems may be configured to support client-to-network, network-to-client, and network-to-network flows in a network element including multiple plug-in units. Such support may include policing and shaping flows as aggregates across plug-in units, combining outputs of two upstream traffic managers to network ports on two plug-in units, combining network flows that ingress two plug-in units, and shaping traffic to client ports.

International Classification:

H04L 12/56

US Classification:

3702301

Abstract:

A method may include monitoring available aggregate bandwidth of a network element and determining if the available aggregate bandwidth is sufficient to communicate traffic at a rate equal to an aggregate sum of committed information rates for a plurality of classes of traffic. If the available aggregate bandwidth is sufficient to communicate traffic at the rate equal to the aggregate sum of committed information rates for a plurality of classes of traffic, traffic may be communicated for each of the plurality of classes in accordance with the respective committed information rate for each class. Otherwise, traffic may be communicated for each of the plurality of classes in an amount proportional to the respective committed information rate for a particular class and the available aggregate bandwidth.

US Classification:

398 2, 370217

Abstract:

A method may include: (i) provisioning a first network-side interface of a first plug-in unit and a second network-side interface of a second plug-in unit as members of a network-side protection group, the first plug-in unit and the second plug-in unit integral to an adaptation layer network element; (ii) provisioning a first client-side interface of the first plug-in unit and a second client-side interface of the second plug-in unit as members of a client-side protection group; (iii) designating one of the first and second network-side interface as an active network-side interface of the network-side protection group; and (iv) designating one of the first second client-side interface as an active client-side interface of the client-side protection group, such that traffic ingressing on the active network-side interface may egress on the active client-side interface and traffic ingressing on the active client-side interface may egress on the active network-side interface.
