A distributed routing system is provided for use in a communication network, wherein the distributed routing system includes at least one cluster comprising a plurality of cluster elements and characterized in that the cluster elements that are used for forwarding communication traffic from among the plurality of cluster elements are synchronized there-between to a single clock and then synchronized to an external communication element, such as a client clock. Optionally, all the cluster elements that are used for forward communication traffic, are configured to implement IEEE 1588 standard and/or Synchronous Ethernet (Sync-E).

Synchronization in distributed communication systems

A distributed routing system is provided for use in a communication network. The distributed routing system comprises a plurality of forwarding modules and a plurality of fabric modules. At least one counter located at at least one respective fabric module is configured to receive data relating to the number of packets being forwarded via physical and/or logical interfaces associated with at least two of the plurality of forwarding modules.

Processing data in a distributed routing system

A network cloud software is provided which is configured to enable operation of multiple hardware network elements as a single routing or switching entity. The network cloud software is used in a distributed manner and provides layers of synchronization and management to allow creation of a network cloud cluster that can start with a single white-box that acts as a stand-alone network device and then scale it to a cluster of tens of hardware elements that would still appear to the external user as a single entity. The network cloud software may also implement mediation layer (HAL) that allows the use of a multi-vendor hardware types by the same network cloud software that is capable of running on a number of different hardware types, while to the external user they will all be seen as devices that have the same functionality and the same network behavior.

System and a method for using a network cloud software

A disaggregated routing system is provided for use in a communication network comprising a plurality of white boxes, wherein at least four of the plurality of white boxes are each configured to carry out a functionality different from the functionalities which the other three of the at least four of the plurality of white boxes are configured to carry out, and wherein each of the at least four of the plurality of white boxes is identified based on its functionality.

Identification of nodes included in a disaggregated system

A network processing element and method for using it, are provided for use in a cluster comprising a plurality of network processing elements, wherein the network processing element is configured to enable provisioning of a plurality of different services, wherein the network processing element is configured to store state data associated with one or more functions required for carrying out each of the plurality of different services, and wherein the network processing element is further configured to provide a service or part thereof, based on the state data associated the network processing element's processing resources required for carrying out one or more functions in the provisioning of the requested service.

Virtualization of multiple network functions in high-scale routing

A communication router, adapted for use in an Open Shortest Path First (OSPF) protocol compliant communication network, is provided. The communication router comprises processing means configured to automatically adjust the communication router's cost metrics set for forwarding communication traffic via at least one link that extends between that communication router and a respective adjacent neighboring router. The cost metrics is adjusted in compliance with costs determined by the respective adjacent neighboring router for forwarding traffic from the respective adjacent neighboring router along that link.

Device and a system for OSPF cost metrics mirroring

A physical network element is provided which is configured to operate as a plurality of separated routing entities, each functioning independently of the others, wherein the physical network element is characterized in that: a) each of the plurality of routing entities is provided with its own control, management and data planes, as well as with a dedicated routing information base table and a forwarding information base table; and b) all of the plurality of routing entities are configured to operate while sharing at least one member of a group that consists of: (i) one or more packet processors comprised in the physical network element; (ii) one or more central processing units (CPUs) comprised in the physical network element; (iii) one or more fabrics comprised in the physical network element; and (iv) one or more network interfaces comprised in the physical network element.

Platform comprising a plurality of routing entities

A method for use in a communication network is provided. The method comprises the steps of: (i) providing a plurality of network processing units (NPU's) comprised in the communication network; (ii) establishing a replication of at least one of the NPU's; (iii) virtually arranging the NPU's and the replication(s) in a ring configuration; (iv) associating a unique primary virtual identification and a corresponding unique backup virtual identification with each active and available entity selected from among the plurality of NPU's and replication(s); (v) establishing a list of hash values, each associated with the primary virtual identification or the backup virtual identification of a corresponding active and available entity; (vi) implementing a ring consistent hashing algorithm for carrying out a search resolution for a consistent hashing; and (vii) in a case of a change in an active and available entity having a certain primary virtual identification, using the corresponding backup virtual identification to maintain the ring continuity.
