Problems solved by technology

Network growth and the increase in the number of network devices has complex management beyond the imagination of the developers of these protocols
In some cases, these protocols may not be sufficient for large numbers of management groups, which can burden larger network management by limiting how routing is done

Embodiment Construction

[0016] figure 1 is a block diagram illustrating an example network system 10 that implements the extended management group techniques described in this disclosure. exist figure 1 In the example, the network system 10 includes a multiprotocol label switching (MPLS) transport network 12 and customer networks 14A, 14B ("customer networks 14"). MPLS transport network 12 represents a network that transports packets or other units of data between networks such as customer network 14 . MPLS transit network 12 may represent a service that implements one or more MPLS protocols, such as Resource Reservation Protocol (RSVP) or Label Distribution Protocol (LDP), to configure one or more Label Switched Paths (LSPs) through MPLS transit network 12 provider network. These LSPs may be dedicated paths for communication between two or more networks, such as user network 14 .

[0017] User network 14 may represent a private network owned and operated by a merchant, government, organization, ...

Abstract

In general, techniques are described for providing extended administrative groups in networks. A network device comprising an interface and a control unit may implement the techniques. The interface receives a routing protocol message that advertises a link. This message includes a field for storing first data associated with the link in accordance with the routing protocol. The field is defined by the routing protocol as a field having a different function from an administrative group field defined by the same routing protocol. The control unit determines that this field has been repurposed to store second data, wherein this second data specifies an extended administrative group for the link different from those that may be specified by the administrative group field. The control unit then updates routing information to associate the advertised link with the extended administrative group and performs path selection to select paths based on the updated routing information.

Description

technical field [0001] The present invention relates to computer networks, and more particularly, to configuring computer networks. Background technique [0002] Typically, devices responsible for routing data through a computer network, such as routers, implement one or more internal network routing protocols, commonly referred to as Interior Gateway Protocols (IGPs), to exchange so-called "routing information" that describes links or paths within a network domain. Examples of IGPs include the Intermediate System-to-Intermediate System (IS-IS) routing protocol and the Open Shortest Path First (OSPF) routing protocol. Each router may resolve routing information by selecting a path through the network for reaching each available destination within the network and generating forwarding information that may be used to forward data packets through the computer network. [0003] Both IS-IS and OSPF routing protocols belong to a class of routing protocols known as link state prot...
