1. A system comprising:

  • a branch office;

    a Wide Area Network (WAN);

    a head office to serve an enterprise application comprising a collaborative document to be shared with the branch office in accordance with a request therefor, the head office and the branch office being configured to communicate through the WAN, the enterprise application further comprising a computed document generated at runtime and a static document prepared a priori; and

    a network of Point of Presence (POP) locations between the head office and the branch office to communicate at least one of the collaborative document, the computed document and the static document on behalf of the head office from a closest POP location to the head office to a closest POP location to the branch office and then onward to the branch office, each POP location including a switching engine and an edge engine implemented therein to provide WAN optimization and application acceleration during the communication of the at least one of the collaborative document, the computed document and the static document on behalf of the head office, the switching engine and the edge engine enabling multi-tenancy in the each POP location, resource allocation for each of the switching engine and the edge engine being on a per-customer branch basis, the each of the switching engine and the edge engine being scalable with load balancers, the WAN optimization and the application acceleration capabilities of the each POP location enabling distribution of tasks associated therewith across the WAN network, at least one of the head office and the branch office being configured to generate secure transport data to be transmitted over at least one secure tunnel of at least one of the collaborative document, the computed document, and the static document between at least one intervening firewall such that traffic is routed securely through the network of POP locations toward a destination, the network of POP locations being implemented with a multi-segment architecture to enable segments of the WAN network to have different queuing and routing policies therebetween based on at least one of cost and congestion, and each segment of the WAN network being capable of implementing a link utilization algorithm using a standard transport protocol therein, wherein the secure tunnel comprises a private transport of a packet with an unaltered Internet Protocol (IP) address through at least one of a Generic Routing Encapsulation (GRE), an Internet Protocol Security (IPsec), a Multiprotocol Label Switching (MPLS), and a Virtual Local Area Network (VLAN).
