High (double-digit) revenue growth in North America and CALA was diminished by declines in Europe, Middle East and Africa (EMEA), and Asia Pacific (APAC).

Market growth was strong in the SP Edge Router and Aggregation Switch segment, while the Core Router segment trended flat.

Supply chain constraints eased somewhat in the quarter, improving access to components and enabling SP Router vendors to work through some of their order backlogs.

Among the top five SP Router Suppliers, Cisco and Juniper recorded solid revenue growth, while Huawei and ZTE declined. Nokia had a strong quarter based on revenue reported in Euros (EUR), but the adverse exchange rate from EUR to U.S. dollars (USD) resulted in a revenue decline in USD.
