Traffic Engineering (TE) in Cisco Crosswork Network Controller optimizes and directs network traffic to meet operational goals like guaranteed bandwidth for prioritized services. It improves network performance by steering traffic along predetermined routes and efficiently using resources. Crosswork Network Controller simplifies management by visualizing SR-TE policies and RSVP-TE tunnels on a topology map, simplifying provisioning and monitoring.
SR-MPLS and SRv6
SR-MPLS and SRv6 are segment routing technologies where the source node encodes the path as a list of Segment IDs (SIDs) in packet headers—MPLS labels for SR-MPLS and IPv6 headers for SRv6. These SIDs guide packets through the network along paths computed by the IGP. Using Cisco Crosswork Network Controller (CNC), users can visualize and manage SR-MPLS and SRv6 policies, including creating, modifying, and monitoring traffic engineering paths, simplifying network operations and enhancing traffic engineering control.
Resource Reservation Protocol (RSVP)
Resource Reservation Protocol (RSVP) is a signaling protocol that reserves network resources and establishes explicit data paths to ensure bandwidth and Quality of Service (QoS) for critical applications. RSVP-TE manages these reservations and tunnels. Crosswork Network Controller supports RSVP-TE by visualizing tunnels, enabling creation of explicit or dynamic paths optimized for metrics like IGP, TE, or delay, and allowing tunnel modification.
Flexible Algorithm
A flexible algorithm is a customizable IGP routing method that defines path constraints using specific metrics and link attributes, enabling routing within logical planes in multi-plane networks. It filters the IGP topology to meet transport policies beyond default shortest paths. Crosswork Network Controller visualizes these topologies to help verify routing behaviors like disjointness, improving service availability and network resiliency.
Tree Segment Identifier Multicast Traffic Engineering
The Tree Segment Identifier (Tree-SID) enables tree-like multicast flows over a segment routing network by assigning a single SID label to represent all segments and devices within a multicast tree.
Deterministic Demand Matrix
The Deterministic Demand Matrix (DDM) provides near real-time visibility into SRv6 traffic demands within IGP domains, showing traffic patterns and potential bottlenecks. It collects detailed traffic data from devices and uses topology and policy information to compute and visualize demands. DDM helps with network monitoring, planning, and troubleshooting by enabling filtering and detailed views per domain and link.
Path analytics service assurance
Cisco Crosswork Path Analytics is a powerful network visibility and automation tool designed to provide real-time computation of Interior Gateway Protocol (IGP) paths. By establishing a live model of network topology via BGP-LS feeds, it enables operators to validate, troubleshoot, and monitor network services with high precision.
