    Abstract: In an embodiment, a method is provided for enabling in-band data exchange between networks. The method can comprise receiving, by a first enveloping proxy located in the first network, at least one regular secure sockets layer (SSL) record for a SSL session established between a client and a server; receiving the data from a network element located in the first network; encoding the data into at least one custom SSL record; and transmitting the at least one regular SSL record and the at least one custom SSL record to an enveloping proxy. In another embodiment, a method can comprise receiving at least one regular secure sockets layer (SSL) record and at least one custom SSL record for a SSL session established between a client and a server; extracting the data from the at least one custom SSL; transmitting the at least one regular SSL record.

    Abstract: An example method is provided in one example embodiment and includes receiving a packet of a session from a previous hop router at a service zone of a service chain; recording the previous hop router for the session; determining an appliance to service the packet in the service zone using load balancing; recording an appliance identity for servicing the session in the service zone; determining a next hop router in the service chain for the packet using load balancing; and recording the next hop router for the session.

    Abstract: Presented herein are techniques to reduce the number of redirected subscriber packet flows while performing sticky hierarchical load balancing. An Nth head end network element may be activated such that a plurality of N head end network elements are active and capable of receiving and processing one or more packet flows. A primary load balancer may then be directed to overwrite a portion of pointers of a hash table in an evenly distributed manner with pointers to the Nth head end network element such that packet flows are forwarded to the Nth head end network element, wherein the hash table retains a static number of entries as the number of head end network elements is modified.
