Nowadays, many Broadband Service Providers are both L2-Wholesale Access Network Sellers and Buyers, while Wholesale-Only, and Virtual-Only Operators are growing both in number and relevance.
Furthermore, Wholesale Access Technologies, previously restricted to copper lines, now include optical cables and Fixed-Wireless-Access with all their permutations.
While offering substantial business opportunities for every Provider in the game, such a wide variety becomes a complex challenge at the Delivery Points.
A Wholesale Buyer has limited choices: Syncing its VLAN Mapping with those of its Sellers; Dedicating some BNGs and hardware resources to each of its Sellers; ReMapping the Sellers VLANs to its own.
The VLAN ReMapping is the choice that offers the most flexibility at the most competitive cost since it allows decoupling the VLAN Mappings without the need for dedicated expensive BNGs and devices.
While the Buyer is the one who requires the VLAN ReMapping, it can also be a relevant value-added service for the Seller.
All the Router/Switch Vendors have implemented VLAN ReMapping, sometimes called Translation or ReTag, feature into their devices.
Those implementations have some common troublesome limitations: their deployment and management are overcomplicated, and there could be at most 128K combinations.
OutSys RescribOS overcomes those limitations with straightforward, flexible deployment, integrated management, and a Full-Matrix Q-in-Q S/C-VLAN ReMapping with 16M combinations.
