Implementations generally relate to network services. In some implementations, a method includes providing a network service having a service mode and a service type. The method further includes generating a network service advertisement message including a service identifier, a service mode portion, and a service type portion. The method further includes-forwarding the network service advertisement message from a first system to one or more other systems via a network. The method further includes-incrementing a counter corresponding to a service mode and a service type pair of each network service advertisement message having a same service identifier. The method further includes, when the counter corresponding to a service mode and a service type pair reaches a predetermined value, blocking configuration of another service having the same service identifier value, service mode and service type as that corresponding to the counter that reached the predetermined value.

Providing network services based on service mode and service type

Systems, methods and computer readable media for network loop detection and prevention are described. Some implementations can include a computerized method comprising detecting, at a first switch, a loop condition in a network, and generating, at the first switch, a localize loop message having an instance count and a path list. The method can also include setting, at the first switch, the instance count of the localize loop message to a first value, and transmitting, from the first switch, the localize loop message to a second switch. The method can further include detecting, at the second switch, a loop in the network; and sending, from the second switch, a localize loop response message to the first switch.

Network loop prevention

Some implementations provide a capability of limiting or blocking configuration of network services based on network service mode and type advertisements. An example method can include providing a network service having a service mode and a service type, and generating a network service advertisement message including a service identifier, a service mode portion and a service type portion. The method can also include populating the service mode portion with a first value corresponding to a service mode of the network service and populating the service type portion with a second value corresponding to a service type of the network service. The method can further include forwarding the network service advertisement message from a first system to one or more other systems via a network.

Limiting network service configuration based on network service type and mode advertisements

A method, system and computer readable medium for security key generation in link aggregation group topologies. The method can include performing, using one or more processors, authentication on each port of a plurality of ports in a link aggregation group. The method can also include deriving, using the one or more processors, a connectivity association key for the link aggregation group. The method can further include computing, using the one or more processors, a security association key for each port in the plurality of ports, the security association key being based on the connectivity association key for the link aggregation group.
